The AirTAC GFR400C15JC2K AirTAC Filter Regulator PT1/2, 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 GFR400C15JC2K is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT1/2 (1/2 in) PT-threaded port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically when flow passes through, a round external gauge reading in psi, and a built-in reverse (check) valve. It is the no-bracket version. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

Installed at the point where the main header drops down to feed a CNC machining cell, cleaning water and swarf-laden particulate from the shop air while holding a steady regulated supply pressure to the cell's air-driven clamps and tool changers.
Mounted on the supply drop feeding the pneumatic cylinders on a carton-forming and sealing conveyor, where the check valve holds the downstream setting during momentary upstream dips and the differential drain clears condensate on every production cycle.
Fitted ahead of a small pneumatic press or forming station, letting the operator read and set working pressure on the external psi gauge while the 40 um element protects the press valve stack from rust and pipe-scale carried in the mill air supply.
Choose the size and port step against the air demand of the line: this unit is size 400 with a PT1/2 (1/2 in) port, the larger step in the GFR range for higher-flow circuits. The 40 um element suits general plant air; specify the 5 um W option where finer filtration is needed. Drain type is a real choice: differential-pressure (fitted here) drains with flow, automatic drains regardless of flow, and manual requires operator attention. The round psi gauge fitted here is the external option; an embedded square gauge with MPa, psi or bar scales is also available. PT is the standard thread, with G (BSPP) and NPT as order options, and this J-coded version omits the mounting bracket. Flow is published as curves, not a single rating, so ask us to confirm sizing against your 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 GFR400 series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your application's air demand and working pressure and we will confirm the sizing from the datasheet curves on request before you order.
The differential-pressure drain fitted here purges collected condensate automatically whenever air flows through the unit, with no operator attention. If your line runs intermittently at low flow, an automatic drain (code A) or a manual drain (code M) version can be specified instead - just ask for the alternative code when ordering.
