The AirTAC GFR40015AJC1WT AirTAC Filter Regulator NPT1/2 5um is a genuine G-series filter regulator: water separation, 5 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 GFR40015AJC1WT is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1/2 in NPT port, a 5 um filter element (code W, finer than the 40 um standard), an automatic drain that ejects collected condensate without manual attention, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an external round gauge scaled in MPa. The polycarbonate bowl suits this size, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part in the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain, filter-grade, gauge, thread and bracket options. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request before you order.

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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding a pneumatic press station: the 5 um element keeps wear particles and water out of the cylinder valves, while the regulator holds the clamping pressure the tooling was set up for and the automatic drain clears condensate between shifts.
Supplying the diverters, pushers and sealing cylinders on a packaging conveyor: the filter stage protects the directional valves from moisture and fines, and the regulated output keeps case-ejection timing consistent as the compressor cycles.
Conditioning the air feeding grippers and small actuators on laboratory automation equipment: the 5 um grade suits instruments sensitive to airborne particulate, the round MPa gauge gives a clear setpoint readout, and the auto drain suits a unit mounted inside a machine frame.
Size 400 with a 1/2 in port is the step to choose when your line's air demand sits above what 3/8 in units carry comfortably; match the size and port to the flow your application needs and we will confirm the fit from the published curves. The 5 um element (W) suits downstream equipment that tolerates less particulate than the 40 um standard element protects. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives on other codes. The round MPa gauge is the external option; embedded square gauges and psi or bar scales exist on other codes. NPT is specified here; G (BSPP) and PT are the other catalogue thread options. This code omits the mounting bracket; bracketed versions are available. Because flow is published as curves rather than a single rating, 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 number here. Tell us your line's air demand and we will confirm the sizing from the datasheet curves before you order.
The A in the code selects the automatic drain, which ejects collected condensate by itself and suits installations that are not checked daily. The same size 400 filter regulator is also available with a manual drain or the differential-pressure default - just ask for the matching code.
