The AirTAC GFR20008MJC3TK AirTAC Filter Regulator NPT 1/4 in 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 series combines a 40 um air filter and a pressure regulator in a single body: compressed air is cleaned of water and particulate, then regulated to your set pressure, in one point-of-use unit. This configuration, GFR20008MJC3TK, has 1/4 in NPT ports, a manual drain, a round gauge with bar scale, a built-in reverse/check valve, and no mounting bracket. The polycarbonate bowl suits the non-freezing -5 to 70 C working range, maximum inlet pressure is 1.0 MPa (145 psi), and with the manual drain fitted the regulation range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and with a choice of drain type (differential-pressure, automatic or manual), 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, G/NPT thread options, and bracket and check-valve options. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm the datasheet and flow 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. |
| J | Supplied without bracket. |
| (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. |
| (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 supply for a machining center's pneumatic clamps and tool-changer cylinders: the 40 um element strips water and particulate from shop air before the regulator sets the working pressure, with the round bar gauge giving the operator a local reading.
Feeding sealers, diverting gates and reject pushers on a packaging conveyor. The 1/4 in NPT ports suit compact point-of-use drops, and the manual drain lets an operator bleed the bowl as part of a shift-start routine.
Regulating clean, dry instrument air on a laboratory or pilot-plant process skid. The filter-regulator keeps filtration and pressure control in one body, and the fitted check valve is part of the specified circuit configuration.
Size the unit by port and expected demand: GFR200 with 1/4 in NPT ports is the compact step in the range, and the larger 300, 400 and 600 sizes carry bigger ports for higher demand - we will confirm the flow curve against your application. This code is fixed as: manual drain, which gives a regulation range of 0.05-0.9 MPa (7-130 psi); 40 um standard filtration (choose code W for the 5 um element if you need finer); a round gauge with bar scale (codes 1 and 2 give MPa and psi scales); NPT thread (G/BSPP is orderable as a code option); and a fitted reverse/check valve with no mounting bracket.
If your line cannot be stopped for draining, an automatic-drain code removes that manual task, and if you want the standard embedded square gauge instead of the external round gauge, that is a different gauge code. Because flow is published as curves and not as a single rating, ask us to confirm sizing from 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 this series as curves, not as a single rated figure, so we do not quote a number here. Ask us and we will confirm the datasheet and check the flow curve for the GFR200 at your inlet pressure against your application before you order.
M is the manual drain: you open it by hand to expel collected water, and on manual-drain units the regulation range is 0.05-0.9 MPa (7-130 psi). The catalogue alternatives are automatic drain (code A) and the default differential-pressure drain, so choose the code that matches how often your installation can be serviced.
