The AirTAC GFR20008MJC1WT AirTAC Filter Regulator NPT1/4 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 GFR20008MJC1WT is a size-200 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/4 in NPT port, a 5 um filter element (code W, finer than the 40 um standard), a manual drain on the PC bowl, a round external pressure gauge scaled in MPa, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range 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, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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. |
| 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. |
| 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. |
| (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.

Cleaning and regulating the shop-air feed to a machining centre's pneumatic tool-changer and clamping circuits, where the 5 um element protects fine valves from water and particles.
Conditioning the air feeding cylinder-driven diverters and pushers on a packaging conveyor, with the manual drain emptied during shift checks and the MPa gauge set for the line pressure.
Supplying cleaned, regulated air to benchtop analytical or test instruments, where the finer 5 um grade and a manually drained bowl suit a supervised, low-duty installation.
Start with the size and port: 200 is the smallest GFR frame, and the 08 position gives a 1/4 in port - step up to 300/400/600 if your line needs more flow capacity. This unit is already specified with the finer 5 um element (W) instead of the 40 um standard, a manual drain instead of the differential-pressure default, a round MPa gauge, and an NPT thread instead of PT; G (BSPP) and PT versions can be ordered if your piping uses those. No bracket is fitted (code J), so plan your mounting accordingly.
Because AirTAC publishes flow only as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering - we will check the datasheet with you.
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. Ask us and we will confirm the flow data from the datasheet against your application before you order.
The M in the code selects a manual drain on the bowl instead of the differential-pressure default. Someone must open the drain periodically to remove collected condensate, which suits supervised installations; with a manual drain the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
