The AirTAC GFR40010MJC3TK AirTAC Filter Regulator 3/8 in NPT 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 PT3/8" 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 GFR40010MJC3TK is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with no lubricator. This 400-size unit is threaded NPT 3/8 in, has a manual drain on the polycarbonate bowl, a 40 um standard filter element, and a round pressure gauge reading in bar. A reverse (check) valve is fitted, and the unit is supplied without a mounting bracket.
It is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) on this manual-drain version. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details 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.
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| 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.

Installed at the drop feeding a CNC machining centre, the unit removes water and particulate from the shop air and holds the regulated pressure that clamping fixtures and pneumatic actuators need.
On a carton-sealing or case-packing conveyor, the filter regulator supplies clean, regulated air to the cylinders and grippers that index, press and eject packs, with the manual drain emptied during shift checks.
At a finishing station, the 40 um element takes water and dirt out of the air line ahead of the spray gun, while the regulator holds the steady atomising pressure the gun setup calls for and the bar gauge gives a direct read.
Within GFR you choose size and port (200/300/400/600 with 1/8 in to 1 in ports) to match the flow your line needs; this unit is the 400 size with 3/8 in NPT ports. Drain type is a real decision: manual (this unit, which also carries the widest 0.05-0.9 MPa adjustment range), automatic, or differential-pressure. Filter grade is 40 um standard or 5 um with code W; gauges are an embedded square gauge as standard or an external round gauge in MPa, psi or bar scales - this unit carries a round bar-scale gauge. Thread is PT as standard with G and NPT as order options, and a bracket can be included or omitted (omitted here). Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and the full datasheet figures for this 3/8 in NPT unit on request.
Code M specifies a manual drain, so condensate is emptied by hand; it also gives the widest regulation range of 0.05-0.9 MPa (7-130 psi). Automatic (A) and differential-pressure (blank) drains are available in the same family if you prefer unattended draining.
