The AirTAC GFR400C15MC2WK AirTAC Filter Regulator 1/2 in PT 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 GFR400C15MC2WK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 5 um filter element (the finer of the two catalogue grades), a manual drain for the bowl, a round pressure gauge reading in psi, and a reverse (check) valve fitted. The port is PT1/2 (1/2 in PT thread), with G (BSPP) and NPT available as order options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series is published in sizes 200, 300, 400 and 600, with a choice of port, thread, drain type, filter grade, gauge style and scale, and check-valve option. Flow figures for the series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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 a workshop air ring that serves pneumatic presses and clamps: the 5 um element strips water and fine particles before the air reaches the valves, and the regulator holds a steady working pressure at each station.
Conditioning the air supply to packaging lines where cylinders actuate sealing bars and product pushers; the check valve helps hold the set pressure against supply dips and the manual drain suits a supervised daily check routine.
Supplying clean, adjustable low-pressure air to laboratory rigs and test benches that need finer-than-standard filtration and a psi-readout gauge at the bench, with the regulator set by hand for each test.
Sizing starts with the port step: this unit is the size 400 body with a 1/2 in PT port, the larger end of the mid-range, so match it to your line's expected flow rather than to pipe size alone - because flow is published as curves, not a single number, send us your application and we will confirm the fit. The choices locked into this code are a 5 um element (versus the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need cleaner air), a manual drain (simple and low-cost, but someone must bleed the bowl periodically; automatic or differential-pressure drains suit unattended installations), a round psi-scale gauge, and a fitted check valve to hold downstream pressure. PT is the standard thread; G and NPT are order options. A mounting bracket is included.
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 rather than a single rated number, so we do not quote a flow figure for this unit. Send us your application details and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects a manual drain: condensate collected in the bowl is released by hand, which suits installations checked daily. If the unit will sit unattended, the automatic (A) or differential-pressure (blank) drain options in the same series remove the need for routine bleeding - we can quote those variants on request.
