The AirTAC GFR400C15AJC2WT AirTAC Filter Regulator NPT1/2 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 GFR400C15AJC2WT is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration has 1/2 in NPT ports, a 5 um filter element (code W; 40 um is the standard grade), an automatic drain that ejects collected condensate without manual attention, a polycarbonate bowl, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No reverse/check valve is fitted and no mounting bracket is included.
It is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and thread options PT (standard), G and NPT. Automatic, manual and differential-pressure drains, 40 um and 5 um elements, gauge styles and scales, and bracket options are all catalogue choices. AirTAC publishes flow as curves rather than a single rated figure, so ask us and we will confirm the 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.

Feeding tool-clamp and coolant-door cylinders on a machining centre, where the 5 um element protects directional valves and the regulator holds a steady clamp pressure.
Supplying pick-and-place and carton-sealing cylinders on a packaging conveyor, with the automatic drain keeping condensate out of the line through long production shifts.
Point-of-use filtration and regulation at a drop leg feeding impact drivers and air tools on an assembly line, with the psi gauge letting operators set and check line pressure at a glance.
The GFR series spans sizes 200, 300, 400 and 600, so step up from GFR200 to GFR600 when the line needs a larger port and more flow; this unit is size 400 with 1/2 in NPT threads. Drain choice matters: automatic (fitted here) ejects condensate without attention, manual needs a periodic press, and the differential-pressure default suits steady duty - note the regulator adjustment range differs by drain type, with automatic and differential-pressure units covering 0.15-0.9 MPa (20-130 psi). Filtration is 5 um with the W code (40 um is standard); pick 5 um where downstream valves and cylinders need finer protection. The round gauge here reads in psi; the embedded square gauge and MPa or bar scales are the other catalogue options. PT is the standard thread; G (BSPP) and NPT are ordered as suffixes. Brackets are optional and this configuration omits one, so plan a rigid mounting if the bowl will be serviced. Flow is published as curves rather than a single rating, so send us your demand 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 as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet before you order.
This unit carries the A code, so the bowl drains automatically: collected condensate is ejected without anyone pressing a button, which suits unattended lines. Manual-drain and differential-pressure versions are catalogue alternatives if you prefer a different service routine.
