The AirTAC GFR40010MJC2TK AirTAC Filter Regulator NPT 3/8 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 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 GFR40010MJC2TK is a GFR400-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is sized 400 with a 3/8 in NPT port, carries the standard 40 um filter element, and drains by hand through its manual drain - you open it as part of routine maintenance rather than relying on an automatic mechanism. It is fitted with an external round gauge reading in psi, and a reverse/check valve is built in to hold downstream pressure if the supply line drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range on this manual-drain version is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with manual, automatic or differential-pressure drains, a 5 um (W) filter element option, embedded square or external round gauges in MPa, psi or bar scales, and a reverse/check valve option. Flow figures for this family are published as curves rather than a single rating, so ask us and we will 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. |
| J | Supplied without bracket. |
| (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.

Point-of-use clean-up and pressure setting on the air feed to a CNC machining centre's pneumatic tool-changer and clamping circuits, with the psi gauge giving the operator a direct setpoint readout at the machine.
Conditioning the supply to cylinder-driven capping and filling heads on a bottling line, where the 40 um element removes water and pipe scale and the regulator holds a steady actuator pressure shift after shift.
A filter-regulator at the drop header of a manual assembly cell feeding air tools and pneumatic screwdrivers, with the reverse/check valve helping hold the set pressure if the main header dips.
Choose GFR400 when your line runs roughly in the 3/8 in port class and you want filtration and regulation in a single body instead of a separate filter and regulator. Step up or down a size (200/300/400/600) to match the port and flow path your machine is plumbed for. On this unit the drain is manual, which suits installations where someone is already at the machine regularly; if condensate loads are heavier or access is poor, an automatic (A) or differential-pressure (default) drain version may be the better choice. The standard element is 40 um; specify the W option for 5 um when downstream equipment needs finer filtration. The gauge here is the external round type with a psi scale (MPa and bar scales are also available), and the K code means a reverse/check valve is fitted. Thread is NPT on this model; PT is the standard thread and G (BSPP) is also a catalogue option. No mounting bracket is included on this configuration (J).
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet curves against your required flow 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 the GFR family as curves rather than a single rated figure, so we do not state a flow number here. Tell us your application and required flow, and we will confirm the datasheet curve figures for this 3/8 in, size-400 unit on request before you order.
The M in the code means condensate is drained by hand - you open the drain as part of routine maintenance, which suits stations that are attended regularly. AirTAC also offers automatic (A) and differential-pressure (the default, blank) drains on GFR400 units, and the manual-drain version carries the wider 0.05-0.9 MPa (7-130 psi) regulation range.
