The AirTAC GFR40015AC2T AirTAC Filter Regulator NPT1/2 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 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 GFR40015AC2T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one compact body. This size 400 unit is specified with a 1/2 in NPT port, the standard 40 um filtration element, and an automatic drain that expels collected condensate without operator attention. The fitted external round gauge reads in psi, so the set pressure can be checked and adjusted at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, an optional 5 um element (code W), gauge scales in MPa, psi or bar, and G (BSPP), NPT or PT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

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 1/2 in air drop feeding a CNC machining cell, the unit strips water and swarf-carrying particulate from the header supply and holds a steady regulated pressure to the machine's pneumatic valves and clamps. The automatic drain keeps condensate moving out of the bowl on a line that runs unattended across shifts.
Mounted on the supply branch to conveyor diverters and packaging-machine cylinders, the filter regulator protects actuators from moisture and dirt while holding the cylinder pressure the machine was set up for. The psi gauge lets a technician verify set pressure during changeover without a separate gauge kit.
Fitted in the compressed-air preparation stage of a truck or trailer assembly and service bay, the unit conditions shop air before it reaches test rigs and air-tool circuits. The automatic drain suits a shared bay where no one is assigned to bleed bowls, and the 1/2 in port matches the bay's supply drops.
Start with the port and size step: size 400 with a 1/2 in NPT port sits in the upper mid-range of the GFR series, so match it against the flow curve for your line rather than a single rating - ask us to confirm the curve figures before ordering. Choose the drain to suit access: this unit has an automatic drain, ideal where the unit is mounted out of reach or on an unattended line; manual and differential-pressure drains are available on other codes. The standard 40 um element suits general plant air protection; specify the 5 um (W) variant if downstream equipment needs finer filtration. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. NPT is built into this code - G (BSPP) and PT threads are order options - and a mounting bracket is included.
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 GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Contact us with your line pressure and air demand and we will confirm the flow-curve figures from the datasheet for this size 400, 1/2 in NPT unit before you order.
This code carries drain option A, an automatic drain that discharges collected condensate without operator attention - useful where the unit is mounted out of reach or on an unattended line. The GFR series is also available with a manual drain (code M) or the differential-pressure drain (blank), which is the default; those variants are separate order codes.
