The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 in PT, 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 GFR200-08 is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 200 configuration has a 1/4 in PT port, a polycarbonate bowl with manual drain, a 40 um filter element, and the low-pressure regulator type. A round gauge scaled in psi is fitted, no mounting bracket is included, and no reverse/check valve is fitted. 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 family spans sizes 200 to 600 with ports from 1/8 to 1 in, plus drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and thread options, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures for your application 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. |
| 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 low-pressure air to spray guns on a finishing line, where the regulator holds a reduced setting and the 40 um element keeps water and grit out of the finish.
Regulating clamp and actuator circuits on compact assembly fixtures; the 1/4 in PT port suits machine drops and the fitted psi gauge reads the setting directly.
Trimming supply pressure on laboratory or pilot pneumatic test rigs specified for the low-pressure regulator type, with the manual drain cleared between test runs.
Every choice in this code is decodable. Size 200 with a 1/4 in PT port suits compact machine drops; step up through sizes 300, 400 and 600 as your port and flow demand grow. The manual drain here means an operator opens the bowl drain by hand to discharge collected water - choose automatic or differential-pressure drain codes where manual attention is impractical. The 40 um element is the standard grade; specify code W for the 5 um option. Gauge scale can be MPa, psi or bar, and thread can be ordered as G (BSPP) or NPT instead of the PT standard. Brackets are optional on this family. This unit is the low-pressure regulator type, so if your circuit operates at reduced settings, confirm the exact setpoint range with us before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing against the application before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
Flow for G-series units is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the sizing from the AirTAC datasheet on request.
This unit's bowl has a manual drain: an operator opens it by hand to discharge collected water and contaminants. If you would rather not rely on manual attention, the same size is available with automatic or differential-pressure drain codes - just ask when ordering.
