The AirTAC GFR400C10JF2G AirTAC Filter Regulator G3/8, 40 um 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 GFR400C10JF2G is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then holds downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) setting range. This configuration has a G3/8 (BSPP) port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowl on this 400 size is polycarbonate.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, optional 5 um filtration (code W), automatic or manual drains, alternative gauge scales, and G or NPT thread options to order. Flow for this series 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 0.15 - 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.

Clean, pressure-stabilised air feeding pneumatic clamps, tool-change actuators and chip-clearing blasts on a machining centre, with the psi gauge giving operators a visible setpoint at the machine.
Conditioned air for conveyor diverters, pusher cylinders and bagging actuators on a packaging line, where the 40 um element keeps water and pipe scale out of close-fitting valves.
Filtered, regulated supply to lab analysers, pneumatic sample-handling fixtures and test rigs, where a stable downstream pressure and a clear psi readout matter more than lubrication.
Start with the port step: this unit is the 400 size with a G3/8 port; step up or down through 200/300/600 sizes as your line size and air demand change. The 40 um element is the standard grade and suits general plant air; specify the W option for 5 um where downstream equipment needs finer filtration. Drain choice matters: the differential-pressure drain fitted here needs no attention at low duty, while automatic (A) or manual (M) drains suit other service patterns. The embedded square gauge reads in psi; external round gauges with MPa, psi or bar scales are available. This code carries no bracket and no reverse/check valve. Thread is G (BSPP); PT is the standard thread for the series, with G and NPT as order options. Because flow is published as curves rather than one rated number, 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 flow for the GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow and sizing from the datasheet before you order.
The differential-pressure drain fitted on this model bleeds collected condensate automatically whenever air flows through the unit, so it suits continuously used lines with no extra attention. If your duty is intermittent or you prefer to drain by hand, the same GFR400 body is available with an automatic (A) or manual (M) drain - ask us for those variants.
