The AirTAC GFR400C15JF2G AirTAC Filter Regulator, G1/2 Port 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 GFR400C15JF2G is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a 40 um standard filtration element and a differential-pressure drain that bleeds collected condensate automatically as pressure drops. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), an embedded square gauge with a psi scale shows the set pressure, and no mounting bracket and no reverse/check valve are fitted on this variant. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the size 400 bowl is polycarbonate (PC).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with stepped ports, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), gauge scales in MPa, psi or bar, an optional external round gauge, and PT, G or NPT threads. Flow figures for this series 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 0.15 - 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.

Feeding clamp cylinders and their valve stack on a production fixture: the 40 um element stops rust and pipe scale reaching the directional valves while the regulator holds a repeatable clamp pressure at the G1/2 supply.
Conditioning air at the drop to spray guns in a finishing booth: water and particulate are stripped before the gun and the set pressure is read directly on the psi square gauge, keeping atomising pressure consistent between operators.
Protecting the diverters, pushers and stopper cylinders on a packaging conveyor: one G1/2 unit filters the shop air and regulates it to the pressure the machine builder specified, with the differential-pressure drain handling condensate in continuous running.
Step through the GFR range by size and port: 200, 300, 400 and 600 cover increasing port sizes and flow demand, so match the size step to the air consumption of the circuit rather than to the pipe alone. Choose the drain to suit access: differential-pressure (this unit) needs no attention while flowing, automatic drains continuously, and manual drain suits infrequently visited installations. Filtration is 40 um as standard; specify the W code for 5 um where finer protection is needed. Gauge scale is selectable (MPa, psi or bar) and an external round gauge is optional; PT is the standard thread with G and NPT as catalogue options, and brackets can be included or omitted (J codes omit them). Because flow in this series 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. 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 performance curves, not as a single rated figure, so we do not quote one number here. Tell us your application and we will confirm the relevant curve and datasheet figures on request before you order.
Differential-pressure drainage is the default: condensate is discharged automatically when the pressure differential across the element rises, with no operator action. The GFR family also offers an automatic drain (code A) for continuous unattended drainage and a manual drain (code M) where you prefer to drain by hand; note the regulation range differs by drain type, with manual-drain versions adjusting from 0.05-0.9 MPa (7-130 psi).
