The AirTAC GFR400C10JF2W AirTAC Filter Regulator 3/8 in PT 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 AirTAC GFR400C10JF2W is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This size 400 unit is built for 3/8 in PT ports, filters to 5 um (the finer of the two catalogue grades), drains condensate by differential pressure, and carries an embedded square gauge reading in psi. It has a polycarbonate (PC) bowl, operates from -5 to 70 C (non-freezing), takes a maximum inlet pressure of 1.0 MPa (145 psi), and no mounting bracket or reverse/check valve is fitted in this configuration.
It is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as standard and G or NPT threads to order, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and square or external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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 0.15 - 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.

Feeds clean, regulated air to the tool-clamp and pallet-lock cylinders on a CNC machining center, with 5 um filtration helping keep moisture and grit out of clamping valves.
Sits on the air line feeding stopper and pusher cylinders on a packaging conveyor, holding a steady set pressure so cartons are squared and stopped consistently shift after shift.
Prepares the air feeding spray guns in a finishing booth: water and particulate are filtered to 5 um and pressure is set at the regulator so each gun sees the pressure the finish calls for.
Start from the port and size: this unit is size 400 with a 3/8 in PT port, one step up from 1/4 in and one below 1/2 in, so match it to the air line feeding your machine and the demand of the actuators downstream. Regulation covers 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain fitted here, and the maximum inlet pressure is 1.0 MPa (145 psi). If you need finer protection than the 40 um standard element, this configuration already carries the 5 um (W) grade; the square gauge reads in psi, with MPa or bar scales and an external round gauge available to order. Thread is PT as standard, with G (BSPP) and NPT as catalogue options, and a mounting bracket can be ordered separately since none is included here.
Flow for the GFR series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request.
The W code sets the 5 um grade instead of the 40 um standard, which suits lines with sensitive valves or finishing equipment. The default drain is differential-pressure: it discharges condensate as the pressure differential across the element rises, with automatic and manual drains available as alternative configurations.
