The AirTAC GFR20008MJC2WG AirTAC Filter Regulator G1/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20008MJC2WG is an AirTAC GFR200 filter regulator: a 5 um filter element and a pressure regulator combined in one body, so a single G1/4 (1/4 in) unit removes water and particulate from compressed air and holds a steady downstream pressure. This configuration has a manual drain on the polycarbonate bowl, a round pressure gauge reading in psi, no mounting bracket and no reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is made in sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and with drain type, filter grade, gauge and scale, thread (PT standard; G and NPT orderable) and bracket options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Fixture clamps on a CNC or manual machining cell need air that is dry, clean and held at a set pressure so parts stay gripped consistently. This unit filters the shop air to 5 um and regulates it in one G1/4 drop before the valve manifold, with the psi gauge letting the setter read the clamp circuit at a glance.
Small pick-and-place and carton-forming cylinders on a packaging conveyor run best on clean, regulated air. Mounted at the line drop, this filter regulator removes water and fine particulate before the directional valves and keeps actuator pressure steady through the shift; the manual drain is bled during scheduled line cleaning.
Spray guns and air-assisted applicators are sensitive to water and fine dirt in the air line, which shows up as finish defects. This 5 um filter regulator at the booth drop cleans the supply and holds a stable gun pressure set on the round psi gauge, with the manual drain emptied as part of booth housekeeping.
Size and port step up together: this unit is size 200 with a G1/4 (1/4 in) G-thread port; larger GFR sizes carry bigger ports for higher air demand. Drain type is a real choice: manual drain needs periodic bleeding of condensate, automatic drain handles it unattended, and the differential-pressure default suits steady supply - this code is manual. Filter grade is 5 um here; 40 um is the standard grade where finer filtration is not required. The gauge is round, reading in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is G (BSPP); PT is the standard and NPT is orderable. No mounting bracket is fitted with this code. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a number here. Send us your application details - the air demand and line pressure - and we will confirm the datasheet and check the sizing of this G1/4, 5 um unit for you before you order.
The M in the code means the polycarbonate bowl has a manual drain: condensate collects in the bowl and someone opens the drain periodically to bleed it off. That suits attended cells and lines with scheduled maintenance. If the unit will sit on an unattended supply line, choose the automatic drain option instead; the catalogue default is differential-pressure drain, which suits steady continuous supply.
