The AirTAC GFR40015JC2GK 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 AirTAC GFR400 series combines two jobs in one body: it removes water and particulate from compressed air and regulates downstream pressure. This configuration, GFR40015JC2GK, is the size 400 unit with a G1/2 (BSPP) port, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises. It regulates between 0.15 and 0.9 MPa (20-130 psi), carries a round psi gauge for setpoint reading, and is fitted with a reverse/check valve (code K) that holds downstream pressure when the upstream supply is lost. No mounting bracket is included (code J). The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, optional 5 um filtration (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, and G or NPT thread options. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet and sizing for your application on request.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.

Mounted at the drop feeding a CNC machining centre's pneumatic tool-changer and clamping circuit, it strips water and chips-laden particulate from the shop air and holds a steady regulated pressure so clamps grip consistently through long production runs. The check valve keeps the clamps held if the main supply dips.
Installed on the airline feeding a carton-sealing machine's flap-fold and taping cylinders, it removes condensate that would otherwise gum the valve spools and regulates pressure so boxes are folded and sealed with repeatable force across shifts. The differential-pressure drain handles condensate without operator intervention.
Fitted at take-off points on a factory compressed-air ring main that serve assorted downstream actuators and air tools, it gives each branch its own clean-air point and an independently set pressure, with the psi gauge letting maintenance staff verify settings at a glance during rounds.
Start with the port and size step: this unit is size 400 with a 1/2 inch port, the right choice when your air line is 1/2 inch and your demand sits in the upper part of the GFR range; step up to size 600 for larger lines or down to 300/200 for smaller ones. Choose the drain to match maintenance reality: the differential-pressure drain fitted here needs no daily attention, the automatic (A) version drains on a cycle, and the manual (M) version costs least but relies on someone opening the drain. The 40 um element fitted here suits general plant air; select the 5 um W grade where downstream valves or instruments need finer protection. The round psi gauge fitted here reads in psi; square-gauge and MPa or bar scales are alternatives. Thread is G (BSPP) as coded; PT is the catalogue standard and NPT is orderable. This J-coded unit ships without a bracket, so plan your own mounting or order a bracketed variant. Because AirTAC publishes flow as curves rather than a single rating, send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes filter-regulator flow as performance curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number on the page. Tell us your line pressure, set pressure and air demand, and we will confirm the flow data from the datasheet and check the sizing for your application on request.
The differential-pressure drain fitted here (the blank drain code) discharges collected condensate automatically as the pressure drop across the 40 um element builds, so it suits installations without daily maintenance visits. AirTAC also offers an automatic drain (code A) and a manual drain (code M) in this family; note that with a manual drain the regulator's adjustment range widens to 0.05-0.9 MPa (7-130 psi), while the differential-pressure and automatic versions are 0.15-0.9 MPa (20-130 psi).
