The AirTAC GFR400C15JC2WG 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 GFR400C15JC2WG is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 400 unit carries G1/2 (BSPP) ports, the 5 um filter element (code W, against the 40 um standard), and a differential-pressure drain, the default drain option for this family. The standard-type regulator adjusts across 0.15-0.9 MPa (20-130 psi) behind a 1.0 MPa (145 psi) maximum inlet, a round pressure gauge reading in psi is fitted, and the unit is supplied without a mounting bracket or a reverse/check valve. The polycarbonate bowl suits the non-freezing -5 to 70 C operating band of this series.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT as catalogue options, plus a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and bracket variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures 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 filtered, regulated air to the tool-changer cylinders and clamping actuators of a machining centre, where the 5 um element protects tight-tolerance valves from particulate in the shop-air ring main.
Conditioning the air branch that drives carton-forming and sealing cylinders on a packaging line, holding a steady set pressure so jaw timing and sealing force stay consistent through the shift.
Supplying regulated air to diverter gates, stoppers and pusher cylinders along a distribution conveyor, with the differential-pressure drain handling condensate carried in from the compressor room.
Every choice in GFR400C15JC2WG is decodable from the code itself. Size 400 with G1/2 ports sits in the middle of the 200/300/400/600 range: step up or down a size when the port or the demand of the line changes, and match the thread to your piping - G (BSPP) here, with PT as the standard and NPT available to order. The 5 um element (W) is the finer of the two published grades and suits downstream equipment that tolerates less particulate carryover than the 40 um standard. The differential-pressure drain is the default; automatic and manual drains are the alternatives elsewhere in the family. The round psi gauge is fitted on this build, while square gauges and MPa or bar scales exist as options, and a bracket can be ordered where this no-bracket configuration needs fixing.
Flow for this series is published as curves, not a single rated figure, so no number is quoted here. Send us your application details and we will confirm the datasheet and sizing against your demand 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 the GFR400 series as curves rather than a single rated figure, so we do not quote a number on the page. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the flow figures from the datasheet for your application before you order.
The W in the code selects the 5 um grade, the finer of the two published options; the standard element is 40 um. Choose 5 um where downstream valves, cylinders or instruments tolerate less particulate carryover. Both grades are genuine catalogue options for the GFR400, and the differential-pressure drain and round psi gauge in this build are unaffected by the element choice.
