The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 5 um Square Gauge 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 GFR200-08 is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and reduces pressure to the set point in a single body. This configuration is size 200 with a 1/4 in NPT port, a manual drain you operate by hand, a 5 um filter element (code W instead of the 40 um standard), an embedded square gauge scaled in psi, and a reverse/check valve fitted. It is the low-pressure regulator type, supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing); the bowl is polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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. |
| J | Supplied without bracket. |
| (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. |
| T | NPT 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, reduced-pressure air to the cylinders and grippers on a packaging line, with the 5 um element protecting valve and seal surfaces and the psi gauge giving operators a readable set point.
Suits a lab bench or test rig where air must be cleaned and held at a low, stable pressure, and the manual drain lets an operator purge the bowl as part of the end-of-session routine.
Supplies the air cylinders that divert cartons on a conveyor sorting line, combining water and particle removal with pressure regulation in one body to save panel space.
Size and port step up with flow demand: size 200 with a 1/4 in port is the lightest step below sizes 300, 400 and 600. This unit carries the 5 um element (W) rather than the 40 um standard, a manual drain instead of an automatic or differential-pressure drain, a square gauge scaled in psi (MPa and bar scales are alternatives), and an NPT thread where PT is the standard and G or NPT are order options. The low-pressure regulator type is chosen when the working set point sits below the standard range; we confirm the exact adjustment range on request. Because flow is published as curves, not a single rating, ask us to check the curve against your application before you order.
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 application details and we will confirm the flow curve and correct sizing from the datasheet on request.
The M in the code sets a manual drain, which you open by hand to purge collected water - a fit where the unit is checked as part of a routine. The W sets the 5 um element instead of the 40 um standard, for finer particle removal. Automatic and differential-pressure drains, the 40 um grade and other gauge scales are available within the same GFR family if your duty differs.
