The AirTAC GFR400C15AJF1T 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 GFR400C15AJF1T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This size 400 unit is threaded NPT1/2, drains condensate automatically, carries the standard 40 um filter element and includes the embedded square gauge scaled in MPa. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, no reverse/check valve is fitted, and the bowl for this size is polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the family include manual or differential-pressure draining, a 5 um element (code W), psi or bar gauge scales, an external round gauge, G or NPT threads and a mounting bracket (not supplied on this code). Flow is published as curves rather than a single rating, so ask us to confirm sizing and full 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 clean, regulated air to the tool-changer and clamping circuits of a CNC machining centre, with the automatic drain handling condensate on a line that runs through the whole shift.
Regulating the air feeding carton-forming and sealing cylinders on a packaging conveyor, so actuator speed stays consistent as the compressor plant pressure drifts during the day.
Serving as the point-of-use filter regulator at a factory air drop that supplies impact wrenches and air cylinders on an automotive assembly line, with the square MPa gauge giving operators a local pressure reference.
Choose GFR when one body must do both jobs: filter and regulate. Step through sizes 200, 300, 400 and 600 as your port and flow demand grows; this unit is size 400 with a 1/2 inch NPT thread. Pick the drain to match your maintenance access: automatic (this code) for hands-off condensate removal, manual for periodic draining, or the default differential-pressure type. The 40 um element is standard; specify W for 5 um where finer particulate protection matters. Gauge scale can be MPa (this code), psi or bar, and the thread can be ordered as PT (the standard) or as G/NPT. Flow is published as curves, not a single rating, so 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 GFR400 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and downstream demand, and we will confirm the flow and the full datasheet figures for this model on request.
The A in this code fits the automatic drain, which ejects collected condensate without daily attention - useful on lines that run unattended. The same GFR400 body can be ordered with a manual drain or the default differential-pressure drain. Note the regulator range differs by drain type: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual.
