The AirTAC GFR40015AJC2TK 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 GFR40015AJC2TK is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 400 unit has a 1/2 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a round external pressure gauge reading in psi. A built-in check valve is fitted, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um elements, gauge styles and scales, and G/NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm the 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.
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Filtered and regulated air feeding the solenoid valves that actuate a carton-forming and sealing station, with the automatic drain keeping condensate out of the valve stack.
Conditioned air for workholding clamps and swing cylinders, where the regulator holds a steady set pressure and the 40 um element protects the clamp circuit from dirt and water.
Regulated air to the pusher and stopper cylinders along a bottle conveyor, with the check valve holding downstream pressure if the upstream supply dips.
Start with the port step: sizes 200 through 600 step up in port and flow capacity, so match the size to the air demand of the circuit rather than the pipe alone. For this family, choose the drain type - automatic for unattended condensate removal, manual for periodic draining, or the default differential-pressure drain. Choose the 40 um standard element for general plant air, or the 5 um W-grade element where finer filtration is needed. Gauge style and scale (MPa, psi or bar), PT versus G/NPT thread, and bracket inclusion are all decodable order choices.
Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering - we will check the datasheet with you on request.
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 flow for this family as curves, not as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures with you on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate without operator attention. The family also offers a manual drain (code M) and a differential-pressure drain as the default, so you can match the drain to how the unit is accessed in service.
