The AirTAC GFR400C15AJC1WT 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 AirTAC GFR400C15AJC1WT is a size 400 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration carries a 1/2 in NPT port, a fine 5 um filter element (the W grade, against the 40 um standard), an automatic drain that bleeds collected condensate from the PC bowl without manual attention, and a fitted round pressure gauge reading in MPa. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates in ambient temperatures of -5 to 70 C (non-freezing). No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the range you can specify manual, automatic or differential-pressure draining, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, 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.

Feeds clean, regulated air to the tool-clamp and pallet-change actuators on a CNC machining centre, with the 5 um element protecting tight-tolerance valves from particulate carryover and the automatic drain handling condensate from a long compressed-air run.
Installed at the drop of a body-shop or trim-line station to regulate supply pressure to air cylinders and grippers, keeping setpoint stable across shift-long duty while the automatic drain keeps the bowl clear without scheduled stops.
Mounted on a packaging conveyor line to condition and regulate air for diverters, pushers and seal jaws, where the round MPa gauge lets technicians verify setpoints at a glance and the 5 um grade shields downstream control valves.
Choose your GFR size by the port and flow demand: this size 400 unit with its 1/2 in NPT port sits in the upper half of the range (200/300/400/600, ports 1/8 in to 1 in), but because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Drain type is a real decision: automatic draining (fitted here) suits unattended duty, manual draining puts discharge in the operator's hands, and differential-pressure draining is the catalogue default. Filter grade is 40 um standard or 5 um for finer protection - this unit carries the 5 um W grade. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales (this unit: round, MPa). Thread is PT as standard with G and NPT as order options - this unit is NPT. A mounting bracket is optional (not fitted here), and a reverse/check valve can be specified where needed.
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, not as a single rated figure, so there is no one rated flow number we can honestly quote for this 1/2 in, size 400 unit. Tell us your application and we will confirm the relevant datasheet figures on request before you order.
This configuration carries the A code, meaning the bowl drains collected condensate automatically without operator attention - useful on unattended or hard-to-reach installations. The GFR family is also available with manual draining or with the differential-pressure drain as the default, and with either the 40 um standard element or this unit's finer 5 um grade, so you can match the drain and filtration to your line.
