The AirTAC GFR400C15C2WGK 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 AirTAC GFR400C15C2WGK is a size-400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration carries a G1/2 (BSPP) port, a 5 um filter element (code W), a differential-pressure drain, a round gauge with psi scale, a reverse/check valve (code K) and a mounting bracket. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. The drain bowl on this 400 size is PC (polycarbonate).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT (standard), G or NPT threads, 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, and a choice of gauge scales. 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 preparation for the air feeding tool clamps and pneumatic actuators on a CNC machining cell: the 5 um element protects downstream valves from particulate and water while the regulator holds a steady setting.
Clean, regulated air for the pick-and-place cylinders and grippers on a packaging line; the fitted check valve helps hold the downstream setting if supply pressure dips.
Regulated air to solenoid valves and diverting cylinders along a conveyor line, with the drain bowl collecting condensate before it can reach the valves.
Choose the size and port against the air demand of the circuit: this unit is size 400 with a 1/2 in G-thread port; larger sizes carry larger ports and more flow. Pick the drain type - differential-pressure (this unit), automatic, or manual - noting the regulation range differs by drain type (0.15-0.9 MPa for automatic and differential-pressure, 0.05-0.9 MPa for manual). Pick the element: 40 um is standard, 5 um (W) suits finer filtration, and this unit carries the 5 um grade. Gauge scale can be MPa, psi or bar (this one is the round psi type), thread can be PT (the standard), G or NPT, and the bracket can be included or omitted. Flow is published as curves, not a single rating - 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow and datasheet figures for this exact model on request.
The 40 um element is the standard grade and suits general plant air; the 5 um W element fitted here filters finer particulate, which is useful ahead of precision valves and cylinders. Both grades are catalogue options across the GFR range, so the choice is a decode option you make when ordering, not a change to any other specification.
