The AirTAC GFR200-08L AirTAC Low-Pressure Filter Regulator 1/4 in 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR200-08L is a low-pressure filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This configuration has a PT1/4 (1/4 in) port, a 5 um filter element (code W), a differential-pressure drain, a round pressure gauge reading in psi, and an integrated reverse (check) valve; it is supplied without a mounting bracket. The polycarbonate bowl suits the 200 size, 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, available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT (standard), G or NPT threads, and manual, automatic or differential-pressure drains. 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. 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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. |
| (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.

Regulating filtered air to clamps and swing cylinders on an assembly fixture, with the built-in check valve guarding the circuit against backflow.
Conditioning low-pressure atomizing air on a paint or coating line, where the 5 um element helps protect nozzles from water and particulate carryover.
Supplying steady low-pressure air to diverters and pushers on a packaging conveyor, with the psi gauge giving operators a local setpoint readout.
Size and port step up together: the 200 size with a 1/4 in PT port suits compact low-pressure circuits, while 300, 400 and 600 carry progressively more flow. Drain type is a real choice in this family - this unit uses the differential-pressure drain, with automatic (A) or manual (M) available. Filter grade is 5 um here (code W); 40 um is the standard alternative. The fitted round gauge reads in psi, and embedded square gauges with MPa, psi or bar scales are options. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is omitted (code J). Flow is published as curves, not a single rating - 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. 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 no one number applies. Tell us your line pressure and air demand and we will confirm the datasheet curve and the correct size for your application on request.
The L code marks the low-pressure regulator variant, intended for circuits that run below standard regulator settings. The exact adjustment range for this variant is not published in our data, so ask us to confirm the range against your setpoint before ordering.
