The AirTAC GFR400C15AJF2T AirTAC Filter Regulator 1/2 in NPT 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 GFR400C15AJF2T is a size 400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration has 1/2 in NPT ports, a 40 um filter element, an automatic drain that removes collected condensate from the polycarbonate bowl, and an embedded square gauge reading in psi. The standard regulator section adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions. It is supplied without a mounting bracket and without a reverse/check valve.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Across the series you can order manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, an external round gauge, G (BSPP) or NPT threads in place of PT, and a mounting bracket. 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.

Point-of-use conditioning on the air drop feeding a CNC machining cell: the 40 um element strips water and swarf-carrying particulate before the regulator holds a steady setting for clamps and tool-change actuators.
Filtered and regulated air for the pneumatic cylinders and diverters on a packaging conveyor line, with the automatic drain keeping condensate out of the bowl across multi-shift running.
Supply air for lab automation and sample-handling equipment, where the regulator holds a fixed pressure for grippers and valves and the psi-scale square gauge gives operators a direct local reading.
Start with the port step: this unit is the size 400 body with 1/2 in NPT ports; smaller and larger GFR sizes cover 1/8 in to 1 in, so match the size to the air demand of the circuit rather than the pipe alone. On drain, the automatic drain fitted here clears condensate without anyone opening the bowl - choose manual or differential-pressure drain codes if you prefer operator-controlled or pressure-differential draining. The 40 um element is the standard grade; specify the W code for the 5 um option where finer particulate capture matters. The square gauge is set to psi here, with MPa and bar scales and an external round gauge available as alternatives. Thread is NPT as decoded; PT is the catalogue standard and G (BSPP) can be ordered. A mounting bracket can be added if you need panel fixing.
Because AirTAC publishes flow as curves and not as a single rated number, we do not quote a flow figure here. Send us your application's air demand and we will confirm sizing against the datasheet curves before you order.
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 here. Tell us your application's air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GFR400C15AJF2T specifies the automatic drain, which removes collected condensate from the bowl without operator intervention. The GFR series is also available with a manual drain or the differential-pressure drain (the blank default), so you can order the drain style that suits how the unit is attended.
