The AirTAC GFR400C10MJF2TK AirTAC Filter Regulator NPT3/8 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR400C10MJF2TK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 400 unit carries a 3/8 in NPT port, a manual-drain bowl in polycarbonate (PC), a standard 40 um filter element and an embedded square gauge scaled in psi. A reverse/check valve is fitted, and the unit comes without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulated outlet covers 0.05-0.9 MPa (7-130 psi) for the manual-drain version, and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um element (code W), G (BSPP) or NPT threads, gauge scales in MPa, psi or bar, and a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet 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 0.15 - 0.9 MPa (20 - 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.

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.

Filtering and regulating the shop-air feed to CNC machining centres and their pneumatic workholding clamps, where clean air at a stable set pressure protects the valves and actuators downstream.
Conditioning the air feeding cylinder-driven grippers and diverters on a bottling or canning line, holding a steady regulator setting despite the condensate load carried in the supply main.
Supplying filtered, regulated air to pop-up diverters and stop gates on a distribution-centre conveyor system, with the fitted check valve holding the set pressure against back-flow.
Choose the size and port against the air demand of the circuit: this unit is size 400 with a 3/8 in NPT port, one step up from size 300 (1/4 in) and one below size 600. Drain type is a real operating choice: a manual drain needs periodic bleeding by hand, while automatic and differential-pressure drains discharge condensate without attention. The standard element is 40 um; specify code W for the 5 um grade where finer filtration is needed. The embedded square gauge here reads in psi, with MPa or bar scales available; G (BSPP) and NPT threads are order options beside the PT standard, and a mounting bracket can be added. Flow is published as curves, not a single rating, so 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application's air demand and we will confirm sizing and the full datasheet figures on request.
This configuration has a manual drain: condensate collected in the PC bowl is released by operating the drain by hand, which suits attended installations with a regular maintenance routine. Automatic and differential-pressure drain variants are available in the same GFR family if unattended discharge is preferred.
