The AirTAC GFR40010MC2TK AirTAC Filter Regulator NPT3/8 with Gauge 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 GFR40010MC2TK is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with the standard 40 um filter element and holds downstream pressure in the 0.05-0.9 MPa (7-130 psi) adjustment range. This configuration is fitted with a manual drain bowl in polycarbonate, an external round gauge reading in psi, a reverse/check valve, and a mounting bracket. The 3/8 in NPT port suits a mid-size air-preparation drop on a machine or line.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices of differential-pressure, automatic or manual, a 5 um element option (code W), and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rating, so we confirm the datasheet figures for your application 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.

|---|---|
| 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. |
| 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.

A filtered, regulated supply point on a factory compressed-air ring main, giving downstream tools and actuators clean air at a set working pressure with a psi gauge for local checks.
Air preparation for a bench-mounted pneumatic press or clamping fixture, where the regulator sets repeatable clamping pressure and the 40 um element keeps water and swarf out of the valve stack.
A single filter-regulator feeding the valve manifold of a packaging or cartoning machine, with the check valve holding the downstream circuit against backflow when the main supply dips.
Size 400 with a 3/8 in port is the step to choose when your line's flow demand sits above what a 300-size unit comfortably serves; match the size to the flow curve, not to port size alone. The manual drain here means an operator opens the bowl drain periodically - choose the automatic drain code if the unit will sit where nobody walks past, or the differential-pressure default for general duty. The 40 um element is the standard grade for general air preparation; specify the 5 um (W) element where downstream valves or instruments need finer protection. The round psi gauge suits US practice; MPa and bar scales are also available. NPT is the thread on this unit; PT is the catalogue standard and G is the other order option. A bracket is included.
Because flow is published as curves rather than a single rating, 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 GFR400 as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, working pressure and approximate air demand, and we will confirm the sizing from the datasheet on request before you order.
The M in the code specifies a manual drain: an operator opens the bowl drain to expel collected water. If the unit will be mounted where it cannot be checked regularly, order the automatic drain (code A) or the differential-pressure drain (blank) variant instead - all three are catalogue options on the GFR400.
