The AirTAC GFR40010MC2T 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 GFR40010MC2T is a GFR400 filter regulator: filtration and pressure regulation combined in a single body, so one unit removes water and particulate from compressed air and holds a set downstream pressure. This configuration decodes as a 3/8 in NPT port, manual drain, standard 40 um filter element, a round pressure gauge reading in psi and a mounting bracket included; no reverse (check) valve is fitted. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl gives a clear view of condensate and element condition.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge style and scale, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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. |
| (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.

Feeding clean, regulated air to the cylinders and actuators on a carton-forming or wrapping machine: the 40 um element catches pipe scale and rust, the regulator holds a steady setting read on the psi gauge, and the manual drain clears collected water at shift end.
Supplying a small pneumatic press or clamping fixture where the operator sets and holds a repeatable downstream pressure; the round psi gauge makes the setting easy to read and the 3/8 in NPT port suits typical machine drops.
Installed at a compressor drop point serving air tools and blow guns in a maintenance area, where the manual drain suits supervised use and the bracket allows tidy panel or wall mounting at the point of use.
The real choices within GFR400 are the port size (larger sizes and ports pass more flow, so step up from 3/8 in if demand is high), the drain type (manual means the bowl is drained by hand; automatic and differential-pressure drains handle condensate for you), the filter element (40 um standard, 5 um with code W for finer protection), the gauge (embedded square as standard, external round optional, in MPa, psi or bar scales) and the thread (PT is the standard; G and NPT are order options - this unit is NPT). A bracket is included. Flow is published as curves, not a single rating, so please 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR400 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 sizing from the datasheet on request.
The M in the code means the condensate bowl is drained by hand, which suits supervised installations. The same GFR400 body is also available with an automatic drain (code A) or the differential-pressure drain (no code letter); ask us to quote the variant you need.
