The AirTAC GFR400C10ALJC2K AirTAC Filter Regulator PT3/8 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.
This GFR400C10ALJC2K is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the low-pressure regulator type, sized for 3/8 in PT ports, with a 40 um filter element, an automatic drain on the polycarbonate bowl, an external round gauge reading in psi, a built-in check (reverse-flow) valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for drain type, 5 um filtration (code W), gauge style and scale, PT, G or NPT threads, brackets and a check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Filtered, regulated air to the clamping cylinders on a CNC machining fixture, with the fitted check valve blocking reverse flow in the clamp circuit.
Conditioning the supply to cylinders and diverters on a carton packaging line, where the automatic drain keeps the bowl clear through continuous shifts.
Supplying stopper and gate cylinders along a conveyor line, with the round psi gauge letting operators verify the set pressure at a glance.
The decodable choices are size and port (here 400 size, 3/8 in PT), the drain (automatic expels condensate without manual attention; manual and differential-pressure types are also catalogued), the filter grade (40 um standard here, 5 um with code W), the gauge (this unit carries the optional external round gauge with psi scale; embedded square gauges with MPa, psi or bar scales are standard), the thread (PT is standard; G and NPT are order options) and the bracket (this code omits it). Because this is the low-pressure type, ask us to confirm its adjustment range against your set pressure. Flow is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing from 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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The A position in this code selects the automatic drain, which expels collected condensate from the bowl without manual attention. The GFR400 is also catalogued with manual or differential-pressure drains if you prefer a different arrangement.
