SMC products are not intended for use as instruments for legal metrology. Measurement instruments that SMC manufactures or sells have not been qualified by type approval tests relevant to the metrology (measurement) laws of each country. Therefore, SMC products cannot be used for business or certification ordained by the metrology (measurement) laws of each country.

Precautions for design

WARNING

1. Consult SMC if no leakage is allowed due to the environment, or operating fluid is not air.
2. External parts including the bowl (Material: polycarbonate) are made of resin. Organic solvents including synthetic fluid, chemicals including acetone, alcohol, ethylene chloride, sulphuric acid, nitrate, hydrochloric acid, cutting oil, kerosene, gasoline, lock material of screw are harmful. Do not use the mist separator where containing those.
3. Effects organic solvents and chemicals, and where these elements are likely to adhere to the equipment.

Chemical data for substances causing degradation (Reference)

Note: Δ: Some effects may occur ×: Effects will occur

When the above factors are present, or there is some doubt, use a metal bowl for safety.

Avoid the application where charge and discharge of pressure to bowl is switched frequently. This may damage the bowl. For this kind of application, the metal bowl is recommended.

Protect from ultra violet ray and radiation heat by shield.

Precautions for design (Continued)

Selection

WARNING

1. Fluorine grease and Mineral grease used on internal surfaces and packing may leak to the outlet. Please contact SMC if this is a problem.
2. N.O. type auto drain should be used under the following requirements to avoid operating failure.
   Output of compressor: 0.75kW or more.
   Discharged flow rate: 100L/min (ANR) or more.
   If multiple auto drains are used, confirm used compressor has capacity over the result of multiplying the above capacity and the number of used auto drains.
   {For example, in case of two auto drain, the compressor need the capacity over 1.5kW [200L/min (ANR)].}
   Operating pressure: 0.1MPa or more at min.
3. N.C. type auto drain should be used under the following requirements to avoid operating failure.
   Operating pressure: 0.1MPa or more at min. for AD27-A, 0.15MPa or more at min. for AD37-A and AD47-A.

CAUTION

1. Do not allow air flow that exceeds the rated flow. If the air flow is allowed outlet side the range of the rated flow even momentarily, drainage and lubricant may splash at the outlet side or cause damage to the component.
2. Do not use in a low pressure application (such as a blower). F.R.L. unit has its own minimum operating pressure and is designed specifically to function with compressed air. If used below the minimum operating pressure, a loss of performance and malfunction can occur.

Installation

CAUTION

1. Do not drop nor apply impact during transportation or installation. This can cause damage to the product.
2. Do not install in areas of high humid or high temperature. It causes damage of the product and malfunction.
3. Connect the mist separator ensuring the direction of "IN" and "OUT" for air direction or an arrow. Wrong connection may cause malfunction.
4. Install vertically so that outlet of drain would turned downward. Use with the outlet of drain turned horizontal or upward causes malfunction.
5. Make a space to provide easy access at the bottom when replacing element or draining bowl. The required space is shown on 「12. Dimensions」 (P24).

Piping

WARNING

1. Blow out or clean piping before piping to eliminate swarf, cutting oil, solid foreign material. Contamination of piping may cause damage or malfunction.
2. When installing piping, avoid chips and sealing materials from piping screws entering the inside of equipment. Or malfunction may occur. When use sealing tapes, leave 1.5~2 threads of the end of thread exposed.

Piping (Continued)

Hold the female screw side and screw in piping with recommended tightening torque. Insufficient tightening torque lead to cause loose piping or sealing failure. Excessive torque may lead to cause screw breakage. Tightening without holding female screw side applies excessive force to the piping bracket which lead to cause breakage.

Recommended torque

*1: First, tighten it by hand, then give it an additional 1/6 turn with a wrench.

Do not apply any torsional moment, or bending moment except the weight of the air filter itself. External piping needs to be supported separately. Hard piping like steel tube is susceptible to excessive moment load or vibration. Insert the flexible tube to cancel the influence.

Before using an SMC fitting and S coupler, please refer to "Tightening the threaded portion of the connection thread" of the Fittings & Tubing Precautions.

Drain guide is not equipped with valve function. Be sure to connect piping for drain. No piping for drain allows the drain and compressed air to exhaust freely. Also, the piping should be performed with drain guide held by spanner to prevent breakage of bowl.

The piping for drain from auto drain should be connected under the following requirements to avoid operating failure.

• AD27-A: I.D. Ф2.5 (Ф3/32") at min., Length 5m (200") at max.
• AD37, 47(N)-A: I.D. Ф4 (Ф3/16") at min., Length 5m (200") at max.
• AD38, 48(N)-A: : I.D. Ф6.5 (Φ1/4") at min., Length 5m (200") at max.

Air Source

WARNING

1. Use clean air. Compressed air containing chemicals, organic solvent, synthetic oil or corrosive gas may lead to cause breakage of parts or malfunction.
2. Air containing too much moisture may cause malfunction. Install the air drier or the aftercooler before the mist separator.

CAUTION

1. Do not install on the inlet side of the dryer as this can cause premature clogging of the element.
2. Install an air filter (Series AF) as a preliminary filter on the inlet side of the mist separator to prevent premature clogging.prevent premature clogging.

Maintenance

WARNING

1. Maintenance and checks should be done by following the procedure in the operation manual. Incorrect handling of the product may cause breakage or malfunction of the equipment or device.
2. Perform periodical check to find cracks, flaws or other deterioration on resin bowl. If any of them is seen, as malfunction is caused, replace with new bowl.
3. Check for dirt in resin bowl periodically. If any dirt is seen, replace with new bowl. And if removing off the dirt by washing instead of using a replacement, never use washing material other than neutral detergent. Otherwise, the bowl is damaged.
4. Open and close drain cock manually. Open and close too much may damage the drain cock.
5. Replace the element before 2 years passed since purchase or pressure drop from initial outlet pressure reaches 0.1MPa. Or the element is broken.

CAUTION

1. Drain the bowl by opening drain cock before the drain level in the bowl reaches element assembly.
2. Rotate the handle counterclockwise (O←direction) to exhaust the condensate of the C2SF(-C)-A. Press the push button to exhaust the condensate of the C3SF(-W)-A and C4SF(-W)-A.
3. Check the element periodically and replace it with a new one if necessary. If it is found that outlet pressure drops or the flow is restricted, check the condition of the element.
4. The manual exhaust for emergency case can be performed by counterclockwise rotation of the handle in AD27-A. (O←direction) For AD37-A, AD38-A, AD47-A and AD48-A, rotate the drain cock counterclockwise in that case. (O-direction)
5. For the N.C. type auto drain, when there is no pressure, condensate which does not operate the auto drain mechanism will remain in the bowl. It is recommended to release the residual condensate manually at the end of the working day.

2. APPLICATION

This instrument aims at, eliminating oil of the air line and solid foreign material of air lines.

3. SPECIFICATIONS

Note1) When the compressor oil mist discharge concentration is 30mg/Nm³(ANR).

Note2) Bowl O ring and other O rings are slightly lubricated.

Note3) Conditions: Inlet pressure: 0.7MPa; The rated flow varies depending on the inlet pressure. Keep the air flow within the rated flow to prevent an outflow of lubricant to the outlet side.
