Safety
1.1 Weight and Bulk
The Heated In-line Filter Pump is relatively heavy (around 38 pounds). Use proper heavy lifting technique to avoid injury.
1.2 Temperature
The filter and pump of the Heated In-line Filter and Pump are both temperature controlled, and the possibility for burns does exist. Unplug the Heated In-line Filter Pump Assembly and allow the heated head of the pump and the heated filter to cool before handling or performing any maintenance on it. One could also use insulating gloves when allowing the pump or filter to cool would be impractical. Exercise caution when moving the assembly before cooling and be sure to use the handle to avoid burns.
1.3 Electrical Shock
The Heated In-line Filter and Pump Assembly is powered by a standard 120 VAC line, meaning potentially fatal shocks are possible. The assembly is no more dangerous than many household appliances in this regard; however, care must
be taken to avoid shock. Before performing any maintenance on the assembly, turn off and unplug the apparatus from the 120 VAC line.
1.4 Operation in Ignition Prone Environments
Extreme caution must be taken when using the Heated In-line Filter and Pump Assembly in combustible or electrically charged environments, as the assembly is not intrinsically safe. The apparatus can potentially ignite flammable gasses, starting a fire or causing an explosion. Use extreme care and thoroughly evaluate the operating environment prior to use.
Principles of Operation
Maintaining a steady temperature around 250°F is important to ensure that moisture, acid gas, and other constituents of the gas stream do not condense before the analyzing equipment. This can result in the damage of equipment as well as the loss of important data. The Heated In-line Filter and Pump Assembly helps to ensure the accuracy of gas samples by providing a heated route for the gas before analysis.
2.1 Heated In-line Filter and Pump Assembly Schematic
2.2 System Components
Figure 1 shows the Heated In-line Filter and Pump Assembly. The assembly was designed for manual operation, requiring manual set up before use.
2.2.1 Temperature Controllers
The Heated In-line Filter and Pump Assembly utilizes two temperature controllers, shown in Figure 1. The temperature controllers are capable of maintaining the user-specified temperature of the filter and pump head.
Additionally, a heated blanket maintains the temperature of the airflow path between the filter and pump at 250° F. Maintaining a steady temperature around 250°F is important so that moisture, acid gas, and other constituents of the gas stream do not condense out, introducing bias and corroding equipment.
2.2.2 Sample Filters and Heated Filter Holder
The filter holder and a glass/PTFE fluorocarbon microfiber filter scrub the sample before it enters the pump. These type of filters have a 99.9% efficiency and are effective up to 500° F. The large size of the filter (1” diameter, 7” long) ensures that the heated in-line filter and pump assembly can be used in many different applications, over long periods of time. However, the filter should be periodically changed to ensure accurate and consistent sampling.
2.2.3 Heated Head Pump
The heated head pump drives the fluid flow of the sample from the extraction point to the analyzer. The pump is functional in ambient temperatures of up to 140°F and the heated head is able to heat the sample contained up to 400° F.
2.2.4 Needle Valve
The needle valve controls the flow of sample air through the filter and the supply flow rate to your analyzer. It is recommended that the user sets the flow rate of the sample air through the assembly before sampling begins. This can be done by connecting a flow meter to the inlet of the filter and adjusting to the desired flow rate using the needle valve. Be sure to disconnect the flow meter after setting your sample flow rate and before sampling, as most flow meters cannot withstand temperatures above 250° F.
2.2.5 Power Requirements
The Heated In-line Filter and Pump Assembly requires a 120 VAC line capable of supplying at least 10 Amps. The whole assembly is protected by a 15 Amp breaker.
2.3 System Operation
2.3.1 Pre-sampling
Unscrew the filter handle and visually inspect the filter element. If particulate has built up on the filter element, extract it and install a new clean filter. Connect the outlet of a flow meter to the inlet of the heated filter. Plug in the assembly and adjust the needle valve so that the pump is pulling at the desired flow rate. This flow rate will probably be determined by the analyzer being used and can be found in the analyzer’s manual. When the desired flow rate is reached, turn off the pump and disconnect the flow meter.
2.3.2 Assembly Setup
Connect the inlet of the heated filter to the sample line. Connect the outlet of the pump to the sample analyzer. Ensure that your sample collector is not currently in the sample stream and run a system leak check. Turn on the heater controller displays and set your target temperatures for the heated filter and the heated head of the pump. A video that shows this process can be found here: http://express.cleanair.com/HeatedSampleLine/temperaturecontroller.html.
When temperatures of the heated filter and heated head have reached your target temperatures, you are ready to sample, and can locate your probe in the gas sample stream.
2.3.3 Sampling
Locate your sampler in the gas stream and begin sampling. The flow rate should stay relatively constant unless you are sampling from a gas stream extremely high in particulate.
2.3.4 High Particulate Applications
If you are sampling in an extremely high particulate application, you must plan to routinely pause sampling to replace the filter if necessary so that your flow rate does not deteriorate.
Routine Maintenance and Inspection

- Always pull clean air through the assembly after completed testing to cleanse the sample gas path
- Check the electrical connections for bent, frayed, or damaged wires
- Leak-check the assembly from inlet of the filter to the outlet of the pump, ensuring that it holds both positive and negative pressure
- Inspect the filter housing gaskets for cracks or tears, and replace if necessary
- Verify that the filter and pump head can heat to approximately 250 °F or desired temperature up to 275 °F
- Lastly, general cleanliness promotes good equipment health as well as accurate test results
Troubleshooting
The Heated In-line Filter and Pump Assembly is very reliable. When something is not working, these points often can provide a solution.
- Unable to pull sufficient sample flow rate
If you cannot achieve your desired flow rate, ensure that the needle valve is in the fully open position. Then check to ensure that the filter is not clogged. If it is not, check the sample line; make sure the line is not crimped or clogged. - System cannot pass a leak check
First ensure that all of your connections to and from the assembly are tight, and connected correctly (not cross-threaded). If one of these connections is not the source of the leak, check the filter gasket to ensure that it is not cracked or broken. If no other source of leakage is found, the diaphragm to the pump may be ripped or cracked and if so, should be replaced. - Temperature controller is heating filter and pump head above temperature set points
If this is happening, check all wires and ensure that they are connected properly and not damaged. If they are connected properly and are not damaged, the relay inside of the temperature controller may be faulty, and must be replaced.
