The AirTAC GFR400-15AJC2T AirTAC Filter Regulator NPT1/2 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 automatic 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 GFR400-15AJC2T is a 400-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1/2 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round pressure gauge reading in psi. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter grades, and gauge options. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Filtering and regulating the air feeding a pneumatic press cylinder, with the automatic drain keeping condensate out of the valve stack between shifts.
Conditioning the instrument-air supply to a bank of pneumatic actuators, with the psi gauge giving operators a local setpoint reading at the skid.
Supplying clean, regulated air to conveyor diverters and bagging heads on a packaging line, where the 40 um element protects downstream control valves.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a 1/2 in NPT port, and larger sizes carry larger ports and more flow. The automatic drain on this model suits installations that are not attended daily; manual drain suits supervised points and differential-pressure drain is the series default. The 40 um element is the standard grade; specify the W code for 5 um where finer filtration is needed. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the other catalogue options. PT is the standard thread and G or NPT are ordered as options - this unit is the NPT version. Bracket fitment is selectable (this model has none).
Flow for the GFR series is published as curves, not a single rated figure, 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 GFR flow as curves rather than a single rated figure, so no single flow number can be stated. We confirm the datasheet and check the curve against your application's air demand on request before you order.
The A in the code GFR400-15AJC2T specifies an automatic drain, which expels collected condensate without daily attention. The series is also available with manual drain or the differential-pressure drain default, and the adjustment range differs by drain type: automatic and differential-pressure drains give 0.15-0.9 MPa (20-130 psi), while manual drain gives 0.05-0.9 MPa (7-130 psi).
