The AirTAC GFR400C15C2W AirTAC Filter Regulator 1/2 in PT 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 GFR400C15C2W is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration has PT1/2 (1/2 in) ports, the finer 5 um filter element, a differential-pressure drain on the bowl, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl and a mounting bracket are included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include manual or automatic drains, the 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and a reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet numbers for your application before you order.

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 cylinders of a stamping or forming press, with the 5 um element protecting directional valves from water and fine dirt carried in shop air.
Supplying packaging machinery grippers, diverters and clamp cylinders, where the round psi gauge lets operators set and check line pressure at the machine without conversion.
Conditioning air ahead of spray guns in a finishing booth, combining water and particulate removal with a stable regulated pressure for consistent atomisation.
Choose the size and port by the air your line consumes: size 400 with PT1/2 ports sits mid-range in the GFR line, and stepping up or down changes both port and flow capacity - we can check the flow curve against your demand if you send the figures. Pick the drain: differential-pressure (this unit) clears condensate as the pressure drop across the element rises, automatic drains operate on their own, and manual drains suit small or intermittently run installations, with the manual-drain variant offering the wider 0.05-0.9 MPa (7-130 psi) regulation range. Pick the element: 40 um is the standard grade and 5 um (this unit, code W) suits finer downstream equipment. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and the bracket complete the selection. Because flow is published as curves rather than 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 this series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet flow figures for this 1/2 in, 5 um configuration before you order.
This unit carries the W option, the finer 5 um grade. The standard grade is 40 um; choose 5 um where downstream valves, cylinders or instruments need cleaner air. Both grades are available across the GFR range, and the differential-pressure drain on this unit clears accumulated condensate as the element loads.
