The AirTAC GFR400C10LC2WT AirTAC Filter Regulator NPT3/8 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 GFR400C10LC2WT is a filter regulator: a filter and a pressure regulator combined in one body, so water and particulate removal and a set downstream pressure come from a single unit. This size 400 configuration has NPT3/8 ports, a 5 um filter element (code W) in place of the 40 um standard, a differential-pressure drain, the low-pressure regulator type, a round psi gauge, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing); the bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with catalogue choices of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Clean, regulated air at a reduced set pressure for the clamp and pusher cylinders on a bottling line, with the 5 um element protecting downstream valves from fine contamination.
Filtered air supply with a low, stable set pressure for hold-down clamps on a machining fixture, where the low-pressure regulator type matches reduced clamping pressures.
Conditioned air for diverter and stop-gate actuators along a packaging conveyor, with the differential-pressure drain and 5 um element keeping moisture and fine dirt out of the valves.
Step the size and port against the flow your line needs: this unit is size 400 with NPT3/8 ports, and smaller or larger GFR sizes step the port and flow capacity up or down. Order the 5 um element (code W) where a point of use needs finer filtration than the 40 um standard; the differential-pressure drain handles condensate without a manual draining task. The L code selects the low-pressure regulator type, intended for reduced downstream set pressures - confirm the exact set-pressure range with us. A round psi gauge is fitted on this model; the catalogue alternative is the embedded square gauge with MPa, psi or bar scales. Thread here is NPT; PT is the standard and G (BSPP) is an order option, and a mounting bracket is included. Flow is published as curves, not a single rating, so 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.
Flow for the GFR400 series is published as curves, not as a single rated figure, so we do not quote a number here. Tell us the flow and pressure your application needs and we will confirm sizing from the AirTAC datasheet on request.
The L code orders the low-pressure regulator type, intended for applications with reduced downstream set pressures. The exact set-pressure range for this variant is not published in the standard tables, so we confirm it from the datasheet on request.
