The AirTAC GFR40015AJC2W AirTAC Filter Regulator PT1/2, 5 um 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 GFR40015AJC2W is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air down to 5 um (the finer of the two catalogue grades) and holds a regulated downstream pressure adjustable from 0.15 to 0.9 MPa (20-130 psi). This configuration is ported PT1/2 (1/2 in, PT thread standard), carries an automatic drain that expels collected condensate without manual attention, and is fitted with an external round gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 400 size; only the 600 size uses an aluminium alloy bowl. No mounting bracket is included on this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 40 um standard element, embedded square or external round gauges scaled in MPa, psi or bar, a low-pressure regulator type, a reverse/check valve, and G or NPT threads in place of PT. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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.

Feeds filtered, regulated air to the tool-change and clamping circuits of a machining centre, with the 5 um element protecting spool valves from fine particulate and the automatic drain keeping condensate off the shop floor without daily checks.
Conditions the air feeding pneumatic cylinders on a cartoning or wrapping line, holding a steady regulated pressure so sealing and forming motions stay repeatable through a full shift.
Supplies regulated air to divertors, stoppers and gate cylinders along a conveyor system, where the automatic drain handles moisture build-up and the psi gauge lets maintenance verify set pressure at a glance.
Choose the size and port step against the air demand of the circuit: the GFR400 with its PT1/2 port sits in the upper mid-range of the family, above the 200 and 300 sizes and below the 600. Because flow is published as curves and not a single rating, we will confirm sizing against your application before you order. On this code the drain is automatic, which suits unattended duty; manual and differential-pressure drains are the other catalogue choices. The 5 um element (code W) is the finer option versus the 40 um standard. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT available as order options, and this code omits the mounting bracket.
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 as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure, downstream set pressure and air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code selects the automatic drain, which expels collected condensate from the polycarbonate bowl without operator attention - useful for unattended or hard-to-reach installations. The catalogue alternatives are the manual drain (M) and the differential-pressure drain (blank), which is the default. All three are available across the GFR range.
