The AirTAC GFR400C15AF2W AirTAC Filter Regulator PT1/2, 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 GFR400C15AF2W is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with PT1/2 (1/2 in) ports, a 5 um filter element for finer filtration than the standard 40 um grade, an automatic drain that expels collected condensate without manual intervention, and an embedded square gauge reading in psi. 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 an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 40 um standard element, alternative gauge scales (MPa/psi/bar) and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Point-of-use filtration and regulation ahead of the pneumatic cylinders and grippers on a carton-forming packaging machine, with the 5 um element protecting downstream valves from fine particulate.
Clean, regulated air for the stopper and pusher cylinders along a bottling conveyor, where the automatic drain handles condensate without a scheduled manual blowdown.
Supplying filtered, pressure-controlled air to sample-handling actuators and air jets on laboratory automation benches, with the psi gauge giving operators a direct local pressure readout.
Size 400 with PT1/2 ports sits in the upper half of the GFR range - step up to size 600 for larger ports and more flow, or down to 300/200 for compact lines. The 5 um element (code W) is the right choice where finer particulate protection matters; the standard grade is 40 um. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives. The embedded square gauge here reads in psi, and MPa or bar scales are available. PT is the standard thread; G (BSPP) and NPT are order options. A bracket is included with this unit.
Flow for this series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering - we will supply the datasheet figures on request.
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 figure, so we do not quote one number. Ask us to confirm the datasheet flow curves against your application and we will supply the figures before you order.
This configuration carries code A, meaning an automatic drain that expels collected condensate on its own - useful where the unit is mounted in a hard-to-reach spot. The GFR series also offers a manual drain and a differential-pressure drain; note that the regulator adjustment range differs by drain type, and this automatic-drain unit covers 0.15-0.9 MPa (20-130 psi).
