The AirTAC GFR400C15JF2GK AirTAC Filter Regulator G1/2, Square Gauge 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 GFR400C15JF2GK is a size 400 filter regulator: it removes water and particulate from compressed air down to 40 um and regulates downstream pressure in one body. This configuration has a 1/2 in (G1/2) female port with G (BSPP) thread, a differential-pressure drain that passes condensate as the pressure differential changes, an embedded square gauge reading in psi, a standard regulation range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve fitted to hold downstream pressure. No mounting bracket is included on this variant.
This is a genuine AirTAC part in the GFR400 series. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include automatic or manual drains, a 5 um filter element (code W), alternative gauge scales (MPa/psi/bar) and an external round gauge. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Clean, regulated air supply to the air cylinders of a small stamping or punching press, with the check valve holding set pressure between strokes.
Filtering and regulating the air feeding gripper and clamp cylinders on a carton-sealing conveyor, with the psi gauge giving operators a local setpoint readout.
Point-of-use air preparation for pneumatic screwdrivers and clamps at a bench assembly station, dropping from a plant header to the tool pressure.
Size 400 with a 1/2 in port sits in the upper-middle of the GFR range; step up to size 600 or down to 300 depending on the flow your line needs - we will confirm the flow curve against your demand before you order. Drain choices are differential-pressure (this unit), automatic (code A) or manual (code M); the standard element is 40 um, with 5 um (code W) for finer filtration. The square gauge here reads psi; MPa and bar scales are alternatives, and an external round gauge is optional. PT is the standard thread, with G (fitted here) and NPT as order options. Brackets are optional on GFR units, and this code specifies none.
Because AirTAC publishes flow only as curves and not as a single rated figure, send us your flow and pressure requirements and we will confirm sizing against the datasheet before ordering.
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 series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
K is the reverse/check valve option: it prevents downstream pressure from flowing back through the unit when upstream supply is lost, helping hold the regulated pressure on the outlet side. This configuration also uses a differential-pressure drain and a square psi gauge; automatic (A) or manual (M) drains and other gauge scales are available as alternative codes.
