The AirTAC GFR40015JF2G 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 PT1/2" 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 GFR40015JF2G is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G1/2 (BSPP) port, the standard 40 um filter element, a differential-pressure drain that bleeds accumulated condensate automatically as flow passes through, and a fitted embedded square gauge scaled in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits operating temperatures of -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 options from 1/8 to 1 inch, thread choices of PT (standard), G and NPT, manual or automatic drain variants, a 5 um element option (code W), and gauge scale choices of MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm flow or 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.

Feeding clean, regulated air to a carton-forming and sealing machine's cylinders, with the psi gauge letting operators set and verify line pressure at the machine.
Supplying filtered, pressure-controlled air to pop-up divertors, stops and gate actuators on a sorting conveyor, with the differential-pressure drain keeping condensate out of the valves.
Conditioning shop air before it reaches pneumatic grippers and lift cylinders on a laboratory sample-handling bench, using the 40 um element and settable regulator output.
Size 400 with a 1/2 inch port sits in the upper-middle of the GFR range; step up to size 600 or down to 300/200 depending on the flow your line needs - we can check the published flow curves against your demand before you order. The differential-pressure drain on this unit is the low-maintenance default; choose automatic drain for unattended duty or manual drain where you want positive control of bowl dumping. The standard 40 um element suits general plant air; specify the W variant for 5 um protection downstream. This unit ships with a square gauge scaled in psi; MPa or bar scales and an external round gauge are options. Thread here is G (BSPP); PT is the standard thread and NPT is orderable. Note the J code means no mounting bracket is fitted - add the bracket option if you panel- or wall-mount the unit.
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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The blank drain code on this model means a differential-pressure drain: condensate is expelled from the bowl automatically when the pressure differential across the filter rises with flow. If you prefer an automatic float drain for unattended duty or a manual drain for positive control, the GFR400 family offers those variants - ask us for the alternative model code.
