The AirTAC GFR400C10LF2W AirTAC Filter Regulator 3/8 in PT, 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 GFR400C10LF2W is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 400 unit is configured with a 3/8 in PT port, 5 um filtration (the finer W grade, versus the 40 um standard element), a differential-pressure drain that removes collected condensate automatically on a pressure differential, a low-pressure regulator type, and an embedded square gauge reading in psi. A mounting bracket is included and no reverse/check valve is fitted. 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 family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm flow and 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.

A fixture-actuation circuit that runs at reduced line pressure: the GFR body strips water and chips-carried condensate at 5 um while the low-pressure regulator holds the clamp force the fixture was designed for, with the psi gauge giving the operator a direct setpoint readout.
Feeding clean, regulated air to filler, capper and labeler actuators on a packaging conveyor: the differential-pressure drain clears condensate as it collects, so the line keeps running without an operator stopping to drain a bowl by hand.
A wall- or machine-mounted preparation point serving several downstream valves and cylinders in a work cell: one 3/8 in unit filters to 5 um and regulates pressure in a single body, with the included bracket fixing it beside the cell drop.
Size and port set the air capacity: the 400 size with its 3/8 in PT connection suits lines running larger pneumatic loads than 200/300 units, but because flow is published as curves rather than a single rated figure, ask us to check the curve against your demand before ordering. This unit carries the 5 um element (code W); choose 40 um for general protection or 5 um where finer particle removal matters - the two grades are the only published options. Drain is differential-pressure here; automatic (A) and manual (M) versions exist if you prefer timed condensate removal or a manual touch. The regulator is the low-pressure type - confirm its setpoint range against your working pressure with us, as the exact range for this type is not published. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are the alternatives. Thread is PT as standard, with G and NPT available to order, and a mounting bracket is included.
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 this family as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Tell us your line pressure and air demand and we will confirm the flow from the datasheet curve for this 3/8 in, size 400 unit before you order.
The W suffix in the code selects the finer 5 um filter element instead of the 40 um standard, and the F2 suffix selects the embedded square gauge with a psi scale (MPa and bar scales are the other options). Both are catalogue decode choices - if you need 40 um filtration or an MPa/bar gauge, ask us for the corresponding code in the same GFR400-10 configuration.
