The AirTAC GFR20008MJC1TK 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 GFR20008MJC1TK is a size-200 filter regulator: it removes water and particulate from compressed air and holds a steady downstream pressure in one compact body. This configuration is a 1/4 in NPT unit with a manual drain bowl in PC (polycarbonate), a 40 um standard filter element, a round pressure gauge scaled in MPa, a built-in reverse/check valve, and no mounting bracket. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit takes a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in. Automatic or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads and brackets are all available in the family. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |
| 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.

Point-of-use filtration and regulation ahead of the solenoid valves and clamping cylinders on a machining centre, keeping chips-out actuation air clean and at a set pressure.
A filtered, regulated air drop feeding pneumatic lab equipment and test rigs, where the manual drain suits a supervised bench environment and the check valve holds the set circuit.
Clean, pressure-set air to impact drivers and pneumatic screwdrivers at a workbench, with the 40 um element catching pipe scale and water before it reaches the tools.
For this 1/4 in NPT unit, step up or down through the GFR200/300/400/600 sizes if your line needs more or less flow - the port grows with the size. The manual drain here must be opened by hand to empty the bowl; choose automatic or differential-pressure drain codes if the unit will sit where regular manual draining is impractical. The 40 um element is the standard grade; specify code W for 5 um where finer filtration is wanted. The round MPa gauge fitted here can be swapped for a square gauge or a psi/bar scale, and PT is the standard thread with G and NPT as catalogue options. If a bracket is needed, pick a code without the J suffix. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs and we will confirm the correct size from the datasheet curves on request.
The M in the code specifies a manual drain bowl, which you open by hand to discharge collected water. If the regulator will be mounted where regular draining is impractical, order the automatic (A) or differential-pressure (blank) drain code instead - the rest of the specification stays the same.
