The AirTAC GFR40015AJC2 AirTAC Filter Regulator PT1/2 Auto Drain 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 PT1/2" ports, a automatic 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 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration has 1/2 in PT ports, an automatic drain that ejects collected condensate without manual attention, standard 40 um filtration, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), and an external round pressure gauge reading in psi. The polycarbonate bowl suits non-freezing installations from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including manual or differential-pressure drains, 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. Flow is published as performance curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Conditions the air feeding pneumatic sealers and clamp cylinders on a packaging line, keeping moisture out of the mechanism while holding a set working pressure for consistent seal quality, with the automatic drain clearing condensate unattended.
Fits ahead of a bench pneumatic press or riveter: filters water and scale from shop air, then regulates the supply to the ram circuit so the operator's set pressure is what the tool actually receives, protecting downstream valves and cylinders.
Supplies clean, regulated air to conveyor diverter and stopper-gate cylinders so gate actuation stays repeatable across a shift, while the automatic drain removes accumulated water without a technician having to visit the line.
Choose the size by port and air demand: this 400-size unit carries 1/2 in PT ports, one step up from the 300 (3/8 in) and below the 600 (3/4 in and 1 in). Drain options are automatic (this unit), manual, or differential-pressure; the adjustment range differs by drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and 0.05-0.9 MPa (7-130 psi) with manual. Filtration is 40 um standard; specify W for 5 um where finer protection is needed. The gauge here is an external round type reading psi; embedded square gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket can be added if needed. Because flow is published as curves rather than a single rating, send us your flow requirement and we will confirm sizing against the datasheet before you order.
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 this series as performance curves rather than a single rated figure, so we do not quote a number here. Send us your flow requirement and port size and we will confirm the datasheet curve and correct sizing on request.
The automatic drain ejects collected condensate on its own, which suits unattended or hard-to-reach installations. Manual and differential-pressure drains are available in the same series; note the regulator's adjustment range starts at 0.15 MPa (20 psi) with automatic or differential-pressure drain and at 0.05 MPa (7 psi) with manual drain.
