The AirTAC GFR400C10LC2WGK AirTAC Low-Pressure Filter Regulator G3/8 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 GFR400C10LC2WGK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation in one body. This configuration is built for a G3/8 (3/8 in) port with G (BSPP) thread, carries the fine 5 um filter element, drains by differential pressure, and uses the low-pressure regulator type. It is supplied with a round external gauge scaled in psi, a reverse/check valve fitted, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the drain bowl is metal.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, covering ports from 1/8 to 1 in, with options for drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, bracket and reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

Feeding air to pneumatically actuated ball and butterfly valves on a process skid where the actuator is rated for a low supply pressure; the unit filters the line air to 5 um and holds the reduced set point, with the round psi gauge giving a local reading at the panel.
Supplying filtered, regulated air to the clamp cylinders on a CNC fixture circuit that runs at reduced pressure to avoid marking soft workpieces; the 5 um element helps keep particulate and condensed water out of the clamp valves.
Regulating low-pressure air to the blow-off nozzles that clear dust and loose film from cartons on a packaging conveyor, with the fitted reverse/check valve for circuits that must not back-feed toward the supply.
Decodable choices on this series: size (200/300/400/600) and port (1/8 to 1 in) stepped against the flow your line needs; drain type (differential-pressure as here, automatic, or manual); filter grade (40 um standard, 5 um as fitted here); gauge (embedded square standard, external round optional) with MPa, psi or bar scale; thread (PT standard, G or NPT to order); bracket; and reverse/check valve. The L in this code selects the low-pressure regulator type; its exact adjustment range is not published, so we confirm it from the datasheet on request.
Because flow is published as curves rather than a single rated figure, send us your application parameters and we will confirm sizing against the datasheet before you order.
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 there is no one number we can quote. Send us your inlet pressure, set pressure and expected air consumption, and we will confirm the sizing from the datasheet on request before you order.
The L in the code selects the low-pressure regulator type and W selects the 5 um filter element; the standard regulator type with the 40 um element is the catalogue default. Drain on this unit is differential-pressure, and the round psi gauge is the external gauge option. If you need a different drain type, filter grade, gauge scale or thread (PT standard, G or NPT to order), we can quote the matching GFR400 configuration.
