The AirTAC GFR200-08 AirTAC Filter Regulator, NPT1/4, Manual Drain 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This configuration is the 200 size with a 1/4 in NPT port, a polycarbonate bowl with manual drain, and the standard 40 um filter element. The embedded square gauge is fitted with a psi scale, and the standard-type regulator adjusts from 0.05-0.9 MPa (7-130 psi). 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 line is offered in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (code W) filtration, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Clean, regulated air for the pneumatic cylinders that index, fill and cap bottles, with the manual drain letting operators bleed off collected condensate at shift start.
Stable downstream pressure for the divert and pusher gates along a parcel-sorting conveyor, where pressure drift would mistime the gate strokes.
Water- and particle-free, oil-free regulated air at the spray gun, where a lubricator would spoil the finish and steady pressure keeps the fan pattern consistent.
Sizing starts with the port step: the 200 size with a 1/4 in NPT port suits circuits built around that connection; step up to 300, 400 or 600 when the line calls for a larger port and more flow. Because flow is published as curves and not as a single rating, ask us to confirm sizing against your application before ordering. The other real choices on this family are drain type (manual on this code; automatic or differential-pressure available), filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar, with an external round gauge optional), thread (PT is the standard; G and NPT are order options), and bracket (not fitted on this code).
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.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number here. Send us your application's flow and pressure requirements and we will confirm the datasheet figures on request before you order.
This unit has a manual drain: the bowl drain is opened by hand to release collected water, which suits stations that are visited daily. If the unit sits in an inaccessible spot or runs unattended, the same 200 size is available with an automatic drain (code A) or a differential-pressure drain (blank code) instead.
