The AirTAC GFR400C15LF2WGK 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 GFR400C15LF2WGK is a GFR400 filter regulator: filtration (water and particulate removal) and pressure regulation combined in one body. This configuration is built for a 1/2 in port with G (BSPP) thread, carries the fine 5 um filter element (40 um is the standard grade), drains its bowl by differential pressure, and is the low-pressure regulator type. A square gauge scaled in psi is fitted, a reverse/check valve is built in, and a mounting bracket is included. The bowl is metal. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
GFR400 is one size within AirTAC's G-series filter-regulator line, which spans sizes 200 to 600 with ports from 1/8 to 1 in and PT, G or NPT thread options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures against your application before ordering. This is a genuine AirTAC part.

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 a 1/2 in air line to clamping fixtures or a pneumatic press, where the job is to strip water and chips from the supply and hold a steady low set pressure at the valve manifold while the cycle runs.
Conditioning the air at a finishing-station drop, where the 5 um element handles water and particulate ahead of sensitive downstream equipment and the regulator lets the operator set a low working pressure for the station.
Supplying cylinders and air-driven diverters on a packaging or conveyor line, where the combined filter-regulator keeps the drop leg clean and the pressure stable and the check valve holds the line against backflow.
The real, decodable choices in this family are the size and port step (200 to 600, 1/8 to 1 in) matched to the flow your line needs; the filter grade (40 um standard, 5 um as fitted here with code W); the drain type (differential-pressure as here, automatic, or manual); the gauge (embedded square standard, external round optional, in MPa, psi or bar scales); the thread (PT standard, G or NPT to order); and the bracket. Note that this unit is the low-pressure regulator type and its exact regulation range is not published in the catalogue - confirm it with us before relying on a set pressure. Because flow is published as curves, not a single rating, ask us to check the GFR400 curve 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 GFR400 series as curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet curve on request before you order.
W is the filter grade: this unit carries the fine 5 um element instead of the 40 um standard. L means it is the low-pressure regulator type; the exact regulation range for the low-pressure version is not published in the catalogue, so confirm the set-pressure window with us. The rest of the code decodes as G1/2 port, G thread, differential-pressure drain, square psi gauge, reverse/check valve fitted and bracket included.
