The AirTAC GFR400C15ALJC1TK AirTAC Filter Regulator NPT1/2 Low-Pressure 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 GFR400C15ALJC1TK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is size 400 with a 1/2 in NPT port, an automatic drain, the standard 40 um filter element, a low-pressure regulator type, a fitted round gauge scaled in MPa, and a reverse (check) valve. 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 unit is metal.
This 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 across the family include manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing 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.

Regulated low-pressure air to the clamping and hold-down cylinders on a carton-sealing line, with the 40 um element keeping debris out of the downstream valves.
Filtered and regulated air feed to spray guns in a paint or coating booth, where the automatic drain clears condensate without anyone attending the unit.
Supply to diverter and stopper cylinders on a sorting conveyor; the fitted reverse/check valve holds the downstream circuit if upstream supply dips.
Within the GFR family you step through sizes 200, 300, 400 and 600 and matching ports (1/8 to 1 in) to suit the flow your line needs; because flow is published as curves and not a single rating, let us check the curve against your demand before you order. The decodable choices on this unit are: automatic drain (manual and differential-pressure drains are the other family options), the 40 um element (5 um with code W), the low-pressure regulator type (its adjustment range is not published, so confirm it with us), a round gauge scaled in MPa (psi and bar scales exist), the NPT thread (PT is the AirTAC standard; G and NPT are order options), a fitted reverse/check valve, and no mounting bracket (brackets are optional).
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 rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this size 400, NPT1/2 unit on request.
This unit carries code A, the automatic drain, which discharges collected condensate without anyone opening the bowl - useful on unattended or hard-to-reach installations. The GFR family also offers manual and differential-pressure drains if your maintenance routine prefers them.
