The AirTAC GFR200-08 AirTAC Filter Regulator G1/4 Manual Drain 5 um 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 AirTAC GFR200-08 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single compact body. This configuration is the 200 size with a G1/4 (BSPP) port, fitted with the fine 5 um filter element (W grade), a manual drain on the PC (polycarbonate) bowl, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure if the upstream supply drops. No mounting bracket is included, so plan to pipe-mount or add a bracket separately.
This is a genuine AirTAC part from the GFR200 series. The GFR line spans 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, thread choices of PT (standard), G or NPT, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard 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. |
| 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.

Feeding clean, regulated air to a machining centre's pneumatic tool-changer and clamping circuits, where the 5 um element protects directional valves from water and fine particles and the check valve holds clamp pressure during supply dips.
Regulating supply to conveyor stopper cylinders and diverters on a packaging line, with the manual drain emptied at shift checks and the psi gauge giving operators a visible setpoint.
Conditioning shop air before it reaches lab analysers or sample-handling pneumatics, where the fine 5 um grade and stable regulated pressure protect sensitive instrument components.
Start with size and port: the 200 series at G1/4 suits lighter-duty lines; step up to 300/400/600 when the circuit demands more flow or a larger port. Choose the drain to match maintenance habits - manual (this unit) needs someone to open the drain, automatic empties itself, and differential-pressure drains on demand. The 5 um element here is the finer option over the standard 40 um, worth it for valves and instruments that tolerate less particulate. The square gauge is fitted in psi; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread, with G and NPT as order options, and brackets are optional.
Because AirTAC publishes flow as curves rather than one rated figure, ask us to confirm sizing against your actual air demand 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 GFR200 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this exact configuration before you order.
A manual drain means someone opens the bowl drain to expel collected water as part of routine checks - simple and reliable where maintenance visits are regular. The 5 um element (code W) is the finer alternative to the standard 40 um element, filtering smaller particles for downstream valves and instruments.
