The AirTAC GFR40015AJC1T 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 GFR40015AJC1T is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the size 400 unit with 1/2 in NPT ports, an automatic drain that ejects collected condensate without manual attention, standard 40 um filtration, and a round pressure gauge on an MPa scale. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl keeps the condensate level visible at a glance.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge styles and scales, and an optional reverse/check valve (K). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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 drop of a plant air main feeding a carton-forming and wrapping line, this filter regulator cleans the compressed air of water and pipe scale and holds a stable working pressure to the line's directional valves and cylinders. The automatic drain handles condensate on a line that runs across shifts without daily bowl checks.
Mounted ahead of the solenoid valves that index a conveyor's stopper and pusher cylinders, this unit strips moisture and 40 um particulate before they reach the valve seats, and the regulator sets the cylinder pressure the line was designed for. The round MPa gauge gives operators a visible setpoint reference at the machine.
Fitted at the point of use on a machining cell's fixture-clamping circuit, this filter regulator protects the clamping valves from water carryover and lets the setter dial in the clamping pressure within the 0.15-0.9 MPa (20-130 psi) range. The 1/2 in NPT ports suit the cell's drop-leg piping without reducers.
Start with size and port: the GFR series steps through sizes 200, 300, 400 and 600, each with larger ports and higher flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone. This unit is size 400 with 1/2 in NPT threads; PT is the standard thread and G (BSPP) or NPT are ordered as options. Choose the drain to suit access: automatic (this unit) suits installations that are not checked daily, manual suits attended points, and the differential-pressure default drains only when the pressure drop justifies it. Filtration is 40 um as standard; specify 5 um (code W) where downstream equipment needs finer protection. Gauge style and scale (MPa, psi or bar) and the bracket option are also decodable choices. Flow is published as curves, not a single rating, 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a rated flow, Cv or l/min figure for this unit. Tell us your application's air demand and working pressure and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GFR40015AJC1T specifies an automatic drain, which ejects collected condensate from the bowl without anyone opening it - useful for units mounted out of easy reach or on lines that run unattended. The family also offers manual drain (code M) and a differential-pressure drain as the default; all three fit the same GFR400 filter regulator function.
