The AirTAC GFR400C15F2G AirTAC Filter Regulator G1/2, 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 AirTAC GFR400 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is the size 400 unit with a G1/2 (BSPP) port, 40 um standard filtration, a differential-pressure drain, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), an embedded square gauge scaled in psi, a mounting bracket, and no reverse/check valve. The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi).
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, plus drain, filter-grade, gauge-scale and thread options. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Point-of-use filtration and regulation for a machining centre's pneumatic clamps, tool changers and air blows, keeping chips and condensate out of the valves while holding a steady setpoint.
Clean, regulated air for cylinder-driven carton forming, sealing and diverting stations on a packaging conveyor, where pressure drift causes misfires and rejected packs.
Filtered and regulated air ahead of spray guns and atomizing nozzles in a finishing line, so water and particles do not spoil the finish and nozzle pressure stays where the recipe sets it.
Pick the size by the flow your line needs: 200, 300, 400 and 600 step up in port and capacity, and this 400 carries a 1/2 inch port. Drain choices are differential-pressure (the default, as fitted here), automatic (code A) or manual (code M); filtration is 40 um standard or 5 um with code W; the gauge can be embedded square or optional external round, scaled in MPa, psi or bar (this unit: square, psi). Thread is PT as the standard, with G (BSPP) and NPT as order options, and a bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements 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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your inlet pressure and the flow your application needs, and we will confirm sizing from the datasheet on request.
F is the embedded square pressure gauge and 2 is the psi scale; MPa (scale 1) and bar (scale 3) versions are available, and an external round gauge is an option. The rest of the code decodes as: size 400, 1/2 inch port, G thread, differential-pressure drain, 40 um filtration, standard regulator, bracket included, no reverse valve.
