The AirTAC GFR400C15ALJF2T AirTAC Filter Regulator NPT 1/2 in 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 See datasheet ports, a differential-pressure 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 GFR series combines filtration and pressure regulation in a single body: compressed air is first stripped of water and particulate, then passed through an integrated regulator so downstream equipment sees a controlled supply. This unit is the size 400 frame with a 1/2 in NPT port, an automatic drain that ejects collected condensate without manual attention, the standard 40 um filter element, and the low-pressure regulator type for applications that operate below ordinary regulated pressures. An embedded square gauge reading in psi is fitted, the unit is supplied without a mounting bracket, and no reverse (check) valve is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. The bowl on this unit is metal.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with a choice of drain type (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT (standard), G (BSPP) or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Feeds the pneumatic grippers and small cylinders on a pick-and-place cell, where the low-pressure regulator type holds a gentle, controlled supply for delicate handling and the automatic drain keeps condensate out of the circuit.
Mounted at the drop of a distribution-centre conveyor line to condition and regulate air for diverter and gate cylinders, with the 40 um element protecting valves from particulate and the psi gauge giving operators a local reading.
Installed ahead of the actuator banks on a bottling or filling line, filtering water and particles from the shop air and regulating it to the level the machine's low-pressure circuit requires, with automatic condensate drainage between shifts.
Start with the port and size step: 1/2 in NPT on the size 400 frame suits lines whose piping and air demand sit at that level - step up to size 600 or down to 300/200 if your distribution piping differs, since larger frames carry larger ports and more flow capacity. Choose the drain to match access: automatic (as here) where the unit is hard to reach or the line runs unattended, manual where an operator drains routinely, or the differential-pressure default. The 40 um element is the standard grade; specify the 5 um W option where finer particulate removal is needed. The fitted square gauge reads psi; MPa and bar scales are alternatives, and an external round gauge is optional. PT is the standard thread across the family, with G (BSPP) and NPT as order options - this unit is specified NPT. A mounting bracket is not included with this configuration. One honest routing note: 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 rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
The A in the code specifies an automatic drain, which ejects collected condensate without operator attention - useful where the unit is mounted in a hard-to-reach spot or the line runs unattended. Across the GFR family you can instead order manual drain (M) or the differential-pressure default, and the manual-drain versions also carry a wider regulator adjustment range. Ask us to confirm the exact range for this low-pressure type on request.
