The AirTAC GFR400C10LF2WK AirTAC Filter Regulator PT3/8, 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 GFR400C10LF2WK is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body. This configuration is built with PT3/8 ports, a 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, and a differential-pressure drain that bleeds condensate automatically as flow passes through. The regulator is the low-pressure type, and the fitted embedded square gauge reads in psi; an external round gauge is optional. A reverse/check valve (code K) is fitted and the 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. The bowl is metal.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads to order. Flow is published as curves rather than a single rated figure, so we confirm the datasheet numbers for your application on request.

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.

Filter, regulate and monitor the air feeding a carton-sealer or wrapper valve manifold, with the 5 um element protecting pilot spools and the psi gauge giving operators a visible setpoint.
Condition the supply to gripper and cylinder circuits on a robotic assembly cell, where the check valve holds the downstream side and the low-pressure regulator suits circuits set well below full line pressure.
Feed blow-off nozzles along a bottling or food conveyor line, with the differential-pressure drain clearing condensate as production air flows and the bracket simplifying mounting at the station.
Start with the size and port: 400 is the larger GFR frame, and PT3/8 suits lines running higher air demand than 1/4 in points; step up or down only against the flow your circuit needs. Choose the filter grade for the downstream equipment: 5 um (this unit, code W) where finer cleanliness matters, 40 um where standard protection is enough. Drain choice matters too: differential-pressure (this unit) drains with flow, automatic drains on condensate level, manual needs a routine drain check. Gauge scale is selectable (MPa, psi or bar - this unit is psi), and thread is PT as standard with G and NPT as order options. A bracket is included here; the J code omits it.
One honest note before ordering: AirTAC publishes flow as curves, not a single rated number, and the exact regulation range of the low-pressure type is not stated as a single figure either. Ask us to confirm sizing and the low-pressure range against your application before you commit.
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 as curves, not as a single rated number, so we do not quote a figure that is not in the catalogue. Tell us your application and we will confirm the flow and the low-pressure regulation range from the datasheet on request before you order.
The W in the code GFR400C10LF2WK selects the 5 um filter grade; the blank default is 40 um. Choose 5 um where downstream valves, actuators or instruments need finer protection from water and particulate. If your application is fine with standard filtration, a GFR400 without the W code carries the 40 um element.
