The AirTAC GFR400C15JC2GK AirTAC Filter Regulator G1/2 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 GFR400C15JC2GK is a size 400 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G1/2 (BSPP) port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, so no manual draining routine is needed. The fitted round gauge reads in psi, and a reverse/check valve is built in to hold downstream pressure when the upstream supply is lost.
This is a genuine AirTAC part in the GFR400 series, one of four sizes (200/300/400/600) that step up in port size and flow capacity, with options including 5 um filtration (code W), automatic or manual drains, square embedded or external round gauges in MPa/psi/bar scales, and PT/G/NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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.

Clean, regulated air feeding a bank of directional control valves on an automated machine, with the check valve holding the circuit's set pressure if the main supply dips.
Conditioning and regulating the air that drives conveyor stopper cylinders and diverters on a packaging or bottling line, with the psi gauge giving operators a local pressure readout.
A point-of-use filter regulator at a factory air drop serving air tools, clamps and blow-off stations, with the 40 um element catching pipe scale and the auto-differential drain shedding condensate.
Size 400 with a 1/2 in port sits in the upper-middle of the GFR range; step up to 600 or down to 300 depending on the flow your line needs, and confirm the choice against the published flow curves before ordering. This unit carries the standard 40 um element, which suits general plant air; specify the W code if you need 5 um for finer protection. The differential-pressure drain is hands-off, but automatic (A) or manual (M) drains are available if your maintenance regime prefers them. The fitted round gauge reads psi; square embedded gauges and MPa/bar scales are the alternatives. Thread here is G (BSPP); PT is the standard thread and NPT is an order option, and the J code means no mounting bracket is supplied. Because flow is published as curves rather than one rating, send us your application details and we will confirm sizing on request.
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 series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and required flow, and we will confirm the datasheet curve figures for this 1/2 in port unit on request before you order.
K means a reverse/check valve is fitted, holding downstream pressure if the upstream supply fails, and C2 specifies the external round gauge with a psi scale. The standard gauge is an embedded square type with MPa/psi/bar scale choices, so this configuration suits a US-market panel where technicians read psi.
