The AirTAC GFR20008MC2GK AirTAC Filter Regulator G1/4 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 GFR200-08G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the GFR200 size with a G1/4 (1/4 in) port, a manual drain on a polycarbonate bowl, a 40 um filter element, an external round pressure gauge reading in psi, and a reverse/check valve fitted. A mounting bracket is included, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, offered with manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and G or NPT thread options. 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. 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. |
| (blank) | Mounting bracket included. |
| (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. |
| 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 the pneumatic clamps and tool-change cylinders on a CNC machining centre, with the check valve holding downstream pressure if the supply dips.
Conditioning the air that drives the sealing and folding cylinders on a carton-forming machine, where the 40 um element protects valve seals from water and debris.
Regulating air to the pop-up diverters and stopper cylinders along a distribution conveyor, with the manual drain emptied during scheduled line maintenance.
Within the GFR line the real choices are the size and port (200/300/400/600, 1/8 to 1 in) matched to the flow your line needs; the drain type (manual on this unit, or automatic or differential-pressure); the filter element (40 um standard, 5 um with code W); the gauge (embedded square standard, external round optional, in MPa, psi or bar); the thread (G here, with PT standard and NPT available to order); the bracket; and the reverse/check valve. The regulation range on this manual-drain unit is 0.05-0.9 MPa (7-130 psi). Flow is published as curves, not a single rated figure, so send us your application and we will confirm sizing against the datasheet 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 GFR200 as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your operating pressure and required flow and we will confirm sizing against the datasheet on request before you order.
The M in the code GFR20008MC2GK specifies a manual drain: collected water is released by opening the drain by hand, typically during scheduled checks. It suits installations where the bowl is easily accessible or where an automatic or differential-pressure drain is not required. Note the manual-drain regulation range is 0.05-0.9 MPa (7-130 psi).
