The AirTAC GFR400C15MJF2WGK AirTAC Filter Regulator G1/2 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 GFR400 series combines water and particulate removal with pressure regulation in a single body. This unit, the GFR400C15MJF2WGK, is a 1/2 in G-threaded port configuration (PT is the standard thread; G and NPT are order options) with a 5 um filter element (code W, against the 40 um standard), a manual drain, an embedded square gauge scaled in psi, a fitted reverse/check valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600, with ports from 1/8 to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and optional brackets; at size 400 the bowl is polycarbonate. Flow is published as curves rather than a single rating, so ask us to 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.

Point-of-use filtration and regulation for a machining centre's tool-changer and clamping circuits: the 5 um element shields downstream directional valves from particles and condensed water while the regulator holds a stable setting.
Clean, regulated air for stopper, pusher and lift cylinders on a beverage bottling conveyor; the manual-drain bowl suits a line that is stopped and checked at the end of each shift.
Particle-filtered, regulated air for test benches and rig instrumentation, where the psi-scaled square gauge gives a direct local reading and the check valve holds downstream pressure if the supply dips.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step up or down through sizes 200, 300, 400 and 600 to match the port and flow your circuit needs. This particular code is fixed as: 5 um element, manual drain, square gauge in psi, reverse/check valve fitted, G thread, no bracket. If you would prefer automatic or differential-pressure draining, a 40 um element, an MPa or bar gauge scale, a mounting bracket, or NPT threads, those are available in neighbouring codes in the same series.
Because AirTAC publishes GFR400 flow as curves and not as a single rated figure, we cannot quote one number here - 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 one number. Tell us your application and we will confirm the flow and datasheet figures on request before you order.
This configuration has a manual drain, meaning the bowl is drained by hand at intervals. It suits installations that are inspected regularly. Automatic and differential-pressure drain options exist in the same series where unattended draining is preferred.
