The AirTAC GFR200-08 AirTAC Filter Regulator G1/4 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR200-08 is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a G1/4 (BSPP) port, a 40 um standard filter element, a manual drain bowl in polycarbonate, a low-pressure regulator type, an external round gauge with a psi scale, and a built-in reverse/check valve that holds downstream pressure when upstream supply is lost. It is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port sizes from 1/8 to 1 inch and options including automatic or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 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. |
| 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. |
| (blank) | Filtering grade 40 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.

Filter, regulate and hold clamp pressure on a CNC fixture circuit: the 40 um element protects the valve and cylinder seals, the check valve holds the clamp if supply pressure drops, and the psi gauge gives the operator a direct reading at the fixture.
Supply filtered, regulated air at reduced pressure to sorting and diverting cylinders on a packaging line, where the low-pressure regulator type suits circuits that run well below full line pressure and the manual drain fits a supervised shift routine.
Feed a single workbench drop or small cell from a plant air main: the unit filters water and particulate, regulates the working pressure for hand tools and small actuators, and the round psi gauge lets the operator set and verify pressure locally.
Choose the size and port step (200 through 600, 1/8 to 1 inch) against the air demand of your circuit, then confirm the match with us: flow for this series is published as curves, not a single rating, so we will check the datasheet against your application before you order. On this unit the drain is manual, so plan a routine blow-down of the bowl; automatic or differential-pressure drain versions are available in the series if you prefer hands-off condensate removal. The 40 um element is the standard grade - specify the W code for the 5 um option if downstream equipment needs finer filtration. This is the low-pressure regulator type; its exact adjustment range is not published in the catalogue sheet, so confirm it with us. The round psi gauge is fitted; embedded square gauges with MPa, psi or bar scales are the alternatives. Thread here is G (BSPP); PT is the standard thread and G or NPT are order options. Brackets are optional - this unit ships without one.
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 figure, so we do not quote a number. Tell us your line pressure, regulated pressure and air consumption, and we will confirm the sizing against the datasheet before you order.
The manual drain (code M) means condensate collected in the polycarbonate bowl is released by operating the drain by hand as part of a routine, rather than automatically; automatic and differential-pressure drain versions are available in the series. The fitted reverse/check valve (code K) holds the regulated downstream pressure if the upstream supply is interrupted.
