WARRANTY pg. 23 2 INTRODUCTION Thank you for purchasing the premium engineered Filtrabox Fume extractor. Its modular construction allows for high performance, easy serviceability and longer life. In addition, the new "slim-line" design reduces the width of the extractor for the most efficient floor layouts. MICRO is designed for the entry level laser user who wants a more economical solution yet still needs excellent performance and extreme space savings. The tiny, yet powerful digital Micro-Blower Module easily extracts dust and fumes from smaller laser applications, circulating the air through the filters and outputting the clean air back into the room. COMPACT X is designed for laser users who need both compact dimensions and high performance for demanding substrates or volume production. Its single Blower Module easily extracts dust and fumes, circulating the air through the filters, outputting the clean air back into the room. EXPAND X-1 is designed for laser users who need more filter capacity as well as greater airflow for demanding substrates and higher volume production. Its single Blower Module easily extracts dust and fumes, circulating the air through the filters, outputting the clean air back into the room. The EXPAND X-1 also has a unique feature, made possible by our PATENT PENDING modular designs, which allows the EXPAND X-1 to be UPGRADED into an EXPANDX-2 simply by adding a Blower Module. The EXPAND X-1 can grow with your business! EXPAND X-2 is designed for laser users who need more filter capacity as well as extreme airflow for demanding substrates and commercial/industrial volume production. With 2 Blower Modules as standard equipment, the EXPANDX-2 can often be set-up to extract from two lasers simultaneously! Its dual Blower Modules easily extracts dust and fumes, circulating the air through the filters, outputting the clean air back into the room. Servicing and maintaining the Filtrabox is a snap. The machine is made up of modular parts, making it easy for you to swap-out and swap-in any module by fastening a few screws and snapping a few cable connections per module. 3 SPECIFICATIONS Voltage Frequency (Hz) Max Current (A) Blower Type Length (mm/inches) Width (mm/inches) Height (mm/inches) Weight (kg/lbs) Max Flow (CFM) Pressure: (in.

MACHINE DIAGRAM MODULES 6 ASSEMBLY INSTRUCTIONS UNPACKING ! Useful Tip: The Filtrabox is shipped in custom packaging for maximum protection during transport. Consider keeping the packaging should you wish to ship the product again. ! Attention: The OXY-Carbon Gas Filter is HEAVY. Each filter weighs approximately 50lbs each. Take appropriate care and precaution when lifting the filter. Remove all the packaging and place all of the parts on the floor. Take inventory of the parts included with your kit: 1. Main Chassis + Blower Module (Pre-Installed) 2. Dust Pre-Filter 3. HEPA Dust Filter 4. OXY-Carbon Gas Filter 5. Lid Module 6. Flex Hose: 4" diameter x 8 feet with hose clamps a. Other hose adapters are optional 7. Power Cord: rated to 15 amps INSTALLATION ! Important Note: The Calibration system will take all the bends and restrictions of the flex hose into account and provide optimal performance. 1. Install the supplied 4" Flex Hose onto the inlet spigot at the top of the machine. Use one of the supplied Hose Clamps to hold it firmly in place. 2. Secure the other end of the supplied 4" Flex Hose to your laser or to any other supplied adapters/fittings with the supplied Hose Clamp. 3. Place the Filtrabox in the final position that it will be regularly used. This is important for Calibration as the system will take all the bends and flow restrictions of the flex hose into account and provide optimal performance. Engage the brakes on the two front wheels to hold the machine in place. 4. Install the supplied power cord onto the back of the Filtrabox and turn it on with the Main Power Switch located on the bottom of the User Interface. 7 ATTENTION! FAILURE TO DEACTIVATE BUILT-IN LASER FANS MAY SEVERELY REDUCE FUME EXTRACTION PERFORMANCE. The Filtrabox fume extractor evacuates fumes by applying a suction flow to the laser system. The laser processing enclosure will therefore be under negative pressure. This state prevents the fumes from escaping from the openings in the laser processing enclosure. Some lasers may have built-in fans within the laser system that push ambient air into the laser processing enclosure that will counteract this negative pressure state, allowing the fumes to escape into the work space. Some laser may have built-in fans within the laser system that push air out of the laser processing enclosure and into the Filtrabox that will also interfere with the airflow control system of the Filtrabox. This may create erroneous airflow readings, false filter life assessments and reduced fume extraction performance. Fans that are not in fluid communication with the laser processing enclosure will not affect the fume extraction performance. For example, cooling fans for electronics components which are located in separate enclosures from the main laser processing enclosure will not disturb the airflow because there isn't a way for the air to pass through from one enclosure to the other. Therefore, all fans in the laser that have the potential for pushing air into or out of the laser processing enclosure must be deactivated. Consult your laser manufacturer for instructions for laser fan deactivation. 8 QUICK START INSTRUCTIONS CALIBRATION & AIRFLOW SETTING SAFETY ! Before connecting the device to a power source, ensure that the main power switch at the front of the device is in the off position "0". ! Avoid plugging or unplugging the unit while it is powered ON ( "I" ). CALIBRATION ! Device must be calibrated to your specific laser engraver to function properly. ! Failure to calibrate the device prior to usage may significantly reduce the life of your filters. 1. Hook up the Filtrabox fume extractor to the Laser Engraver, with the supplied hose or with the hose you intend to permanently use for the application. Arrange the laser, Filtrabox and the hoses into their desired locations. This is important because the calibration process takes the restrictions caused by the bends in the hose and positioning of the equipment into account. 2. ! Pressing the "OK" button will trigger the Calibration process which will take approximately one minute. If the calibration process fails, try restarting the system and ensuring that nothing is obstructing the inlet or hose. If the calibration process continues to fail, contact Filtrabox Technical support for help. 3. If you wish to Calibrate Filtrabox to a new application, press the "Menu" button. Press the right arrow key to advance the screen until you reach the "New Application Calibration" section. Press the "OK" button to initiate Calibration. The Calibration process will take approximately one minute. 9 AIRFLOW % SETTING ! USEFUL TIP 1: Use the "4-6 second rule" to determine adequate evacuation of the laser; the "Airflow %" setting should be set to the value where you can observe full evacuation of the fumes from the laser enclosure within 4-6 seconds from the instant that the laser stops engraving/cutting. Check by opening the laser top cover 4-6 seconds after the laser stops. There should NOT be any fumes visible. If you cannot achieve the 4-6 second rule, you can try the 6-8 second rule, which is also acceptable. Set your "Airflow %" to the lowest possible setting that will adequately evacuate the fumes from your laser. This ensures that you are using your filters to their maximum potential which minimizes costs. ! USEFUL TIP 2: Start by setting your Filtrabox at 15% for a small sized laser or 25% for a medium sized laser, or 40% for a large sized laser and incrementally increase up from those starting points, using the 4-6 second rule to determine the minimum adequate evacuation setting. SETTING THE AIRFLOW% SETTING 1. The Status screen is the first screen shown once the device has finished calibrating or finished booting up. The device will display the current flow setting. 2. Turn on the blower by pressing the "Power" button while in the "MANUAL" setting. 3. Set the "Airflow %" to the desired starting point by pressing the "UP" or "Down" buttons. ! USEFUL REMINDER: Start by setting your Filtrabox at 15% for a small sized laser or 25% for a medium sized laser, or 40% for a large sized laser and incrementally increase up from those starting points, using the 4-6 second rule to determine the minimum adequate evacuation setting. 4. Start engraving/cutting on the most smoke/odor generating substrate you will typically use. 5. Adjust the "Airflow %" until you see significant movement of the fumes towards the laser intake vents. 6. Check to see if you have achieved the adequate evacuation flow using the 4-6 second rule or the 6-8 second rule. 7. Continue adjusting your flow until you are satisfied with the performance. The "Airflow %" value will be automatically saved to memory. 10 ! The AUTO-COMPENSATION FLOW CONTROL feature, which is standard on the Filtrabox, will maintain the set-point "Airflow %" by automatically increasing power to the blowers as the filters get obstructed by the dust. You do not have to manually change the "Airflow %" setting again unless you change your laser or use a more fume generating substrate. Note: "Airflow %" represents the Airflow potential of your system. 8. When the laser is not in use, press the "Power" button to turn the blower(s) off. 9. Filtrabox has an EZ-link feature that allows you to turn the blowers ON or OFF remotely from the laser (if this feature is available on your laser). See the EZ-LINK section of the manual. YOUR FILTRABOX LASER EXTRACTOR IS NOW SET-UP FOR OPERATION. 11 FILTER REPLACEMENT INSTRUCTIONS ! When the "Check Filter" warning comes on, increasing the "Airflow %" value WILL NOT increase actual airflow. The "Check Filter" warning indicates that the "Airflow %" set-point can no longer be achieved despite the fact that the power applied to the blower by the "AUTO-COMPENSATION FLOW CONTROL" feature is at maximum value. This is most likely due to airflow blockage in the pre-filter or HEPA filter from normal usage. The Filtrabox Compact and Expand systems have 3 types of filters; Pre-Filter, HEPA filter and OXYCarbon Filter. 1. Pre-Filter FIL-P-CX-427: Collects fine dust 2. HEPA Filter FIL-P-CX-417: Collects ultra-fine dust 3. OXY-Carbon Filter FIL-G-CX-407: Adsorbs and destroys odor causing gases. All three filters will need to be independently replaced at some point in time during the course of normal usage. "CHECK FILTER" WARNING ! Replacement filters can be purchased from: info@filtrabox.com or call 514.840.9696 ext. 102 The "Check Filter" warning will appear on the screen when either Dust filters (Pre-Filter and/or the HEPA) filter need replacement. When the "Check Filter" warning comes on, increasing the "Airflow %" value WILL NOT increase actual airflow. The "Check Filter" warning indicates that the "Airflow %" set-point can no longer be achieved despite the fact that the power applied to the blower by the "Dynamic Flow Control" feature is at maximum value. This is most likely due to airflow blockage in the Pre-filter or HEPA filter from normal usage. 12 "FILTER CHECK" FEATURE ! Useful Tip: Check for obstructions in the hose before ordering a new filter. An obstruction in the hose may cause an erroneous "CHECK FILTER" WARNINGS. ! The Pre-Filter captures the majority of dust generated by the laser. Therefore, it is the most frequently replaced dust filter in the system. ! Replacement filters can be purchased from your dealer or: info@filtrabox.com or call 514.840.9696 ext. 102 1. If the "CHECK FILTER" warning comes on, go to the User Interface and press the "Menu" button. Press the "left or right arrow" button to scroll through the menu functions until you find the "CHECK FILTER" feature. 2. Press the "OK" button to initiate the "CHECK FILTER" process. 3. Filtrabox will assess the status of all the Dust Filters in your systems and then prompt you to remove the Pre-Filter. Follow the instructions on the screen. 4. To remove the Pre-Filter first loosen all four Strap Clamps on the Lid, then unhook the Strap Clamps and pull the lid straight up by the two Handles. 5. Remove the Pre-Filter and set it aside, then put the Lid back onto the HEPA Filter as in the image below. Hook the Strap Clamps back onto to the Lid and ensure that they are tight. 6. Follow the prompt on screen and press the Enter Button to continue. 7. Filtrabox will then advise you to replace either the HEPA or the Pre-Filter depending on their actual conditions. Or, the system will advise you to consider upgrading to a more powerful model if the Airflow% setting is too high, which would cause the filters to be inefficiently used (causing frequent filter changes). 8. When the filter check is complete, replace the Pre-Filter making sure that the Strap Clamps are tightened. 13 REPLACING THE DUST PRE-FILTER FIL-P-CX-427 !

Press the "OK" button to select the setting: OPERATING MODE SETTING There are 3 Modes of Operation. In all three modes, the user always controls the "Airflow %" setting by simply pushing the "UP or Down" buttons at any time. To select the mode, press the "Up or Down" arrows to scroll the options below and press the "OK" button to confirm your selection. 1. Manual Mode (On/Off) This mode allows the user to manually choose the on/off state of the blowers in the Filtrabox. This is the default mode. Toggle "ON/OFF" by pressing the "Power" arrow key. The blower(s) will be engaged to the previously set "Airflow %" 2. Link On/Off This mode uses the DB9 connection at the rear or the Filtrabox. The blowers will be engaged at the previously set "Airflow %" when Laser requests it. (If feature is available on the Laser.) When the Laser does not require any airflow, the system automatically deactivates the blowers. If there is no laser system connected, the blowers will never engage. See the Controller Set-up and Pin-Out example at the end of the manual. 3. Link On/Idle This mode uses the DB9 connection at the rear or the Filtrabox. The blowers will be engaged at the previously set "Airflow %" when Laser requests it. (If feature is available on the Laser.) When the Laser system does not require operating airflow, the system continues idle at a very low setting to contain fumes from the off-gassing of lasered materials, and off-gassing of dust in the Filtrabox or the Laser enclosure. See the Controller Set-up and Pin-Out example at the end of the manual. 18 FILTER CHECK SETTING See the FILTER CHECK Feature in Filter Replacement Instructions. NEW APPLICATION CALIBRATION SETTING ! This will initiate the Calibration sequence. Avoid doing this unnecessarily. This should only be used if you are changing lasers, length of hose, diameter of hose; or anything that would change (reduce or increase) the airflow restrictions in the entire system. Calibration should only be done with a new set of filters otherwise the filter check feature will not function as intended. While in the "New Application Calibration" setting, press the "OK" button to initiate Calibration. The Calibration process will take approximately one minute. SERVICE MENU SETTING This menu is only to be used by Filtrabox Technicians or with the guidance of a Filtrabox Technician. 19 EZ-LINK CONTROLLER SET-UP AND PIN-OUT COMPACT AND EXPAND DB9 PIN-OUT Start Exhaust System Pin 9 Pin 1 Check Filter Figure 1: An example of a D-Sub 9 connector COMPACT AND EXPAND Pins 4 & 5: Normally Open Output from Laser Controller The controller connects these two pins to start the exhaust system. Pins 8 & 9: Normally Open Input to Laser Controller The exhaust system should connect these two pins when the filter check status appears on the extractor. 20 EZ-LINK Electrical Requirements Figure 2 below shows the required circuit for the output on the laser's filter control system. When the laser's filter control unit wishes to turn on the exhaust system, the contacts on the relay are closed, thus connecting the two output pins. These output pins correspond to pins 4 & 5 on the exhaust system. When creating a circuit to detect when these two wires have been connected, no more than 200 mA may pass through these wires. Figure 2: The circuit for the "start exhaust system" signal. When creating the "Check Filter" signal, the two wires for the signal should be shorted together using a relay. This means that the exhaust system will not actively dump any current through these wires. The laser's filter control unit should use approximately 30 mA to detect when those wires have been connected. EZ-LINK Control Operations The filter control operation is very simple. When a user begins to run a laser engraving/cutting job, the filter controller turns on the exhaust system immediately. When the job has been cancelled, paused, or finished, the laser's filter control unit should wait 15 seconds or more before turning off the exhaust system. This allows any extra fumes to be evacuated from the laser engraver. 21 SUPPORT For any and all questions related to our Filtrabox products and accessories, please do contact us anytime.
