The AirTAC GFR20008MLF2WK AirTAC Filter Regulator 1/4 in PT, 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 GFR20008MLF2WK is a filter regulator: water and particulate removal plus pressure regulation combined in a single body. This 200-size unit is specified with a PT1/4 (1/4 in) port, the low-pressure regulator type, a fine 5 um filter element (W code), a manual drain on the PC bowl, an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in and thread options PT (standard), G and NPT. Drain, filter grade, gauge scale and check-valve choices vary by code. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| (blank) | PT 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.

Air-prep point for clamping cylinders and swing clamps on a machining or assembly fixture, where clean, regulated air at a low set pressure holds parts consistently through the cycle.
Supply conditioning for test rigs and laboratory benches running pneumatic instruments at reduced pressures, where the low-pressure regulator type and 5 um element protect sensitive gear.
Feeding small actuators and air jets on a packaging conveyor line, with the 5 um grade keeping fine particulates out of compact valves and the square psi gauge giving a clear setpoint readout.
Choose the size and port step (200 through 600, 1/8 in to 1 in) against the air demand of the circuit, then confirm the match with us before ordering - flow is published as curves, not a single rating, so we check the datasheet against your application. For this family the real decode choices are: drain type (manual, as fitted here, versus automatic or differential-pressure), filter grade (5 um as in this code, versus the 40 um standard), gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options), and bracket. The L code makes this the low-pressure regulator type - tell us your working pressure band and we will confirm suitability from the catalogue.
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 this series as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet before you order.
The M code gives a manual drain: condensate collected in the PC bowl is released by hand, which suits attended installations - automatic and differential-pressure drains are available on other codes. The W code is the fine 5 um element, one step below the 40 um standard, for circuits that need cleaner air.
