The AirTAC GFR20008MC3WTK AirTAC Filter Regulator NPT1/4 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 GFR20008MC3WTK is a size-200 filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body, with a 1/4 in NPT port. This configuration carries the 5 um filter element (code W) for finer contaminant removal than the 40 um standard, a manual drain for the PC (polycarbonate) bowl, a round pressure gauge reading in bar, and a built-in reverse/check valve. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with this manual-drain version, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, square or round gauges with MPa, psi or bar scales, G, NPT or PT threads, and bracket options. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

|---|---|
| 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. |
| 3 | Gauge scale: bar. 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.

Feeding filtered, regulated air to pneumatic clamps and fixtures on a machining centre, where the 5 um element protects precision valves from particles and water carried in the shop air line.
A point-of-use filter regulator on the 1/4 in drop feeding cylinders and diverters on a carton or bottle packaging conveyor, with the check valve holding the downstream circuit if upstream pressure dips.
Conditioning the compressed air feeding lab automation equipment and analytical instrument actuators, where the bar-reading gauge lets technicians set and verify the working pressure at the bench.
Choose the size and port step (200 through 600, 1/8 in to 1 in) against the air demand of the circuit; the 200 size with 1/4 in NPT suits compact point-of-use drops. Pick the drain to match maintenance practice: manual (this model) requires someone to open the drain, while automatic and differential-pressure drains discharge condensate without operator action. Select 40 um for general protection or 5 um (W) where finer filtration is wanted, and match the gauge scale (MPa, psi or bar) to your operators. Thread is PT as standard with G and NPT as orderable options; brackets are available where panel or wall mounting is needed. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
The M in the code specifies a manual drain: condensate collected in the PC bowl is released by operating the drain by hand, which suits lines checked as part of a routine. If you prefer unattended condensate removal, the same filter regulator is available with an automatic drain (code A) or a differential-pressure drain (blank); note the regulator adjustment range differs by drain type, with the manual-drain version covering 0.05-0.9 MPa (7-130 psi).
