The AirTAC GFR400C15JC2G AirTAC Filter Regulator G1/2, 40 um 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 GFR400C15JC2G is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted 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 is high enough. Outlet pressure is set across the standard 0.15-0.9 MPa (20-130 psi) range, and a round gauge scaled in psi is fitted so the setting can be read directly. No mounting bracket is included with this code.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch. Within the series you can order alternative thread options, an automatic or manual drain, a 5 um element (code W), different gauge styles and scales, and a bracket. Published flow data appears as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding filtered, pressure-set air to the pneumatic cylinders and grippers on a carton-forming or case-packing conveyor, where the differential-pressure drain keeps condensate moving out without daily manual blowing down.
Conditioning the air at a spray-booth or finishing-line drop so water and pipe-scale are stripped out before the air reaches the spray equipment, with the outlet pressure held steady at the setting the gun or pump needs.
Mounted in the air-preparation panel of a CNC machine or press, giving the machine's valve stack one clean, regulated supply point, with the psi gauge letting setters verify the circuit pressure at a glance.
Start with the size and port: 400 is the larger step in the GFR range and carries a 1/2 inch port, so match it against the air consumption of the circuit it feeds - we can check the published flow curves against your demand before you order. For the drain, this unit uses the differential-pressure type, which needs no attention at set intervals; choose the automatic (code A) or manual (code M) variant if your maintenance routine prefers it. The 40 um element fitted here suits general plant air; specify 5 um (code W) where finer pre-filtration is wanted. The round psi gauge fitted on this code can be swapped for other gauge styles and scales (MPa, psi or bar), and PT or NPT threads are order options if G is not your plant standard. Flow is published as curves, not a single rating, so please ask us to confirm sizing against the application 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 the GFR series as curves, not as a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Send us your application's air demand and we will confirm the sizing from the datasheet curves on request before you order.
The C2 code on this model specifies an external round gauge scaled in psi. The embedded square gauge is the series standard, and round or square gauges with MPa, psi or bar scales are all catalogue options, so you can order the GFR400 in the gauge style and scale your panel prefers.
