The AirTAC GFR400C15AJC2WGK AirTAC Filter Regulator G1/2 5 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 GFR400C15AJC2WGK is a GFR400-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is size 400 with a G1/2 (BSPP) port, the finer 5 um filtration grade, an automatic drain, a round gauge reading in psi, and a built-in reverse/check valve; no mounting bracket is included with this code. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating 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 including manual or differential-pressure drains, 40 um standard filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.

Cleaned and regulated air for tool-changer and workholding clamping circuits on a machining centre, with the 5 um element guarding fine pilot valves.
A point-of-use filter regulator feeding carton-forming and sealing cylinders on a packaging conveyor, holding a steady setting shift after shift.
Conditioned, regulated air at the drop of a pick-and-place assembly cell, with the check valve holding the downstream circuit if supply dips.
Pick the size step (200/300/400/600) and port against the flow your line needs - here size 400 with a G1/2 port. Drain type is a real choice: the differential-pressure default, manual, or automatic as on this code, which suits unattended installations. Filter grade is 40 um standard or 5 um (code W, fitted here) for finer protection. Gauges are the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options; this code is G thread. A bracket is optional and not included here. 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 flow for the GFR400 as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this exact model on request.
The 40 um element is the catalogue standard; the W code on this model fits the 5 um element for finer protection of valves, cylinders and instruments downstream. The automatic drain on this unit removes collected condensate without manual attention.
