The AirTAC GFR400C15LC2WG 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 GFR400C15LC2WG is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, the fine 5 um filter element (code W) instead of the 40 um standard element, a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element is high enough, and the low-pressure regulator type for circuits that run below standard regulator settings. A round external pressure gauge with a psi scale is fitted so the set pressure can be read directly at the unit, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports, G/NPT thread options, 40 um or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulator types, gauge styles and scales, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the flow or datasheet 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.

On a carton-sealing or case-packing line, this filter regulator cleans the supply air to 5 um and holds a low regulated pressure for clamping and hold-down cylinders, with the psi gauge letting operators verify the setting at the machine.
Bottling and canning conveyors use air-actuated diverters and stop gates that run at reduced pressure. This G1/2 unit conditions the supply and regulates it in one body, while the differential-pressure drain keeps condensate out of the valves.
Pneumatic positioners, transmitters and sample-handling gear in a process area need clean, low-pressure air. The 5 um element protects the instruments and the low-pressure regulator type suits the reduced supply pressure they expect.
Start with the port step: size 400 with a G1/2 port sits in the upper half of the GFR range, so match it against the pipe size and the air demand of the circuit. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. On filtration, this unit already carries the fine 5 um element (code W); choose it over the 40 um standard element when downstream valves, cylinders or instruments need cleaner air. On drainage, the differential-pressure drain fitted here is the default and needs no operator attention; an automatic drain or a manual drain can be specified instead if your maintenance routine prefers them.
The low-pressure regulator type in this code is intended for circuits that run below standard regulator settings - confirm the exact adjustment range with us for your set pressure. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is G (BSPP) here, with PT as the standard and G/NPT as order options. A mounting bracket is included with this unit.
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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow from the datasheet against your required consumption before you order.
The W in the code specifies the fine 5 um filter element in place of the 40 um standard element, and C2 specifies the optional external round gauge with a psi scale (the embedded square gauge with MPa/psi/bar scales is the standard alternative). Both are catalogue decode choices, so you can order the same size 400 G1/2 filter regulator with the 40 um element, a square gauge or a different scale if that suits your circuit better.
