The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 NPT Low-Pressure 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 filter regulator: water and particulate removal plus pressure regulation combined in one body. This size 200 unit is threaded 1/4 in NPT and is built as the low-pressure type (code L) for circuits that run at reduced settings; the exact adjustment range is not published, so we confirm it on request. It carries the finer 5 um filter element (code W), a manual-drain polycarbonate bowl, an external round pressure gauge reading in psi, and an integrated reverse/check valve (code K). No mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for drain type, 40 um or 5 um filtration, gauge style and scale, PT/G/NPT threads and brackets. 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). |
| 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. |
| 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.

Set a steady reduced supply pressure for spray guns and air-assisted applicators on a finishing line, with 5 um filtered air and a local psi gauge at the point of use.
Feed bench-top pneumatic fixtures and test rigs that operate at reduced pressure, where the low-pressure type regulator and built-in check valve hold the setting against backflow.
Filter and regulate air to carton sealers and light packaging actuators, with the manual drain bled at shift end as part of the line's housekeeping routine.
Size 200 with a 1/4 in NPT port suits circuits plumbed at 1/4 in; step up to 300, 400 or 600 for larger ports and more flow - we confirm the flow curves against your demand before you order. This is the low-pressure type, chosen when the circuit works below standard regulator settings; its exact range is not published, so confirm it with us if the setpoint is critical. The 5 um element is the finer of the two catalogue grades (40 um is the standard alternative). Drain is manual, so the bowl is bled by hand at intervals; automatic and differential-pressure drains are available elsewhere in the family for unattended duty. The gauge here is the external round type reading psi; the embedded square gauge and MPa/bar scales are the other options. NPT is an order option alongside the PT standard and G thread, and this configuration is supplied without a mounting bracket.
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, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
The L code makes this a low-pressure regulator for circuits operating below standard settings; the exact adjustment range is not published, so confirm it with us before ordering. The M code gives a manual drain, meaning you bleed the bowl yourself - well suited to attended installations, while automatic or differential-pressure drains suit unattended duty.
