The AirTAC GFR400C15F2WK 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 GFR400C15F2WK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This 400-size unit is threaded PT1/2, carries the 5 um (W) filter element instead of the standard 40 um, drains condensate by differential pressure, and is fitted with an embedded square gauge scaled in psi plus a reverse (check) valve; mounting bracket included. The metal bowl collects the separated water and debris.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi); operating temperature is -5 to 70 C, non-freezing. Flow for this size is published as curves rather than a single rating - ask us and we will 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.

Filter and regulate the air feeding pneumatic clamps on a machining fixture, so clamp force stays consistent through the shift while the 5 um element protects the clamp valves from fine particulate.
Condition the air ahead of a paint or coating line: water and particles are stripped out and pressure is set at the panel, keeping spray equipment supplied with clean, steady air.
Supply filtered, regulated air to diverters, pushers and grippers on a carton or bottle line, with the check valve helping hold downstream pressure while the upstream supply fluctuates.
Size and port are the first decision: 400 is the larger step in the GFR range, and the port (here PT1/2) should match your line and the air delivery your actuators need - we confirm sizing against the published flow curves before you order. Then set the options: drain type (differential-pressure as here, automatic, or manual), filter grade (40 um standard, 5 um with the W code for finer protection), gauge scale (MPa, psi or bar; embedded square gauge standard, external round gauge optional), the reverse/check valve (K), thread family (PT standard; G and NPT to order) and bracket.
One honest limit: because AirTAC publishes flow as curves, not a single rated figure, we do not quote a flow number here - send us your application details and we will confirm 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 GFR400 as curves, not a single rated number, so we do not quote a figure here. Tell us your line pressure and the flow your application needs, and we will confirm the datasheet curve and suitable sizing on request.
The W code selects the 5 um filter element instead of the standard 40 um, for finer protection of downstream valves and cylinders. The K code adds a reverse (check) valve, which helps hold downstream pressure if the upstream supply drops. Both are catalogue options on the GFR family.
