The AirTAC GFR200-08G 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 GFR200-08G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 200 unit has a G1/4 (BSPP) port, a 40 um standard filter element, a manual drain for hand-bleeding collected condensate, and the low-pressure regulator type. A round external gauge with a psi scale is fitted, a reverse/check valve is built in, and a mounting bracket is included. 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. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application before ordering.

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). |
| 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.

Feeds filtered, regulated air to workholding clamps on a machining centre; the manual drain lets the operator bleed accumulated water from the bowl as part of the start-of-shift routine.
A point-of-use filter regulator ahead of the pick-and-place cylinders on a carton packaging line, keeping the air clean and the working pressure steady at the machine.
The low-pressure regulator type suits bench and pilot-plant air circuits that run at reduced set pressures, with the built-in reverse/check valve preventing backflow through the unit.
The real choices in this series are the size and port step (200 through 600, 1/8 to 1 inch), which you match to the air demand of the circuit; the drain type (manual here, or automatic or differential-pressure); the filter grade (40 um standard, 5 um with code W); the gauge (embedded square as standard, or an external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge); the thread (PT is the standard, G and NPT are order options); and the bracket. The L in the code marks the low-pressure regulator type; its exact adjustment range is not published, so confirm your set point with us. Because flow is published as curves rather than a single rated figure, ask us to check 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 we do not quote a number here. Send us your air demand and line pressure and we will confirm the correct size and the datasheet flow curves for this unit on request.
The M in the code means condensate collected in the bowl is released by hand: you open the drain manually to bleed off accumulated water instead of relying on an automatic or differential-pressure drain. It suits installations where an operator can check the bowl as part of a routine. The bowl on this size 200 unit is polycarbonate.
