The AirTAC GFR20008MJC2WGK 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 AirTAC GFR200 series combines water and particulate filtration with pressure regulation in a single body, so one unit both cleans the compressed air and holds your downstream pressure steady. This configuration, GFR20008MJC2WGK, is the size 200 unit with a G1/4 (BSPP) port, a fine 5 um filter element (the W grade, finer than the standard 40 um), a manual drain on the bowl, a round pressure gauge reading in psi, a built-in reverse/check valve, and no mounting bracket. The standard regulator covers 0.05-0.9 MPa (7-130 psi) and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). The polycarbonate bowl lets you see condensate at a glance; with a manual drain you simply open it during checks to empty collected water.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with matching ports, a choice of drain types (manual, automatic or differential-pressure), 40 um or 5 um filtration, gauge style and scale options, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding directional valves and cylinders on a packaging or cartoning line, this filter regulator removes water and fine particles and holds a steady set pressure, with the psi gauge giving operators a visible setpoint at the machine.
At a point of use where analyser enclosures, air bearings or test rigs need cleaner air, the 5 um element and stable regulated output protect sensitive components, and the manual drain suits a station checked each shift.
Supplying impact drivers, nutrunners and air ratchets at a bench or cell, this unit keeps moisture and grit out of the tools while the regulator sets the pressure the job needs, and the check valve holds the downstream circuit if supply dips.
Start with size and port: the GFR200 shown here is the compact step in the range, and larger sizes (300/400/600) carry bigger ports and more flow capacity, so match the size to the air demand of the machine it feeds. Then choose the drain: manual (this unit) suits installations visited during routine checks, while automatic or differential-pressure drains empty the bowl without operator action. Filtration grade is your next choice - 40 um is the standard element for general plant air, while the 5 um W grade fitted here protects more sensitive valves, cylinders and instruments. Gauge style and scale (square embedded or round external; MPa, psi or bar) and the thread (PT is the standard; G and NPT are order options) complete the configuration, with a mounting bracket available where the unit is not wall- or manifold-fixed. Because flow for this series is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the datasheet flow curve and sizing for this G1/4 unit on request before you order.
The M in the code specifies a manual drain: you open the bowl drain during routine checks to release collected condensate. If the installation is unattended, the same GFR200 body is available with an automatic drain (code A) or a differential-pressure drain (the default, blank code) instead.
