The AirTAC GFR400C15AC2T 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 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 GFR400C15AC2T is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size 400 unit is threaded NPT1/2, drains condensate automatically, filters to the standard 40 um grade, and carries a round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is made in four sizes (200, 300, 400, 600) with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT to order, plus choices of drain type, 40 um or 5 um filtration, gauge style and scale, and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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.

Filtered air at a held setpoint for the cylinders that open, close and divert cartons along a packaging conveyor line.
Stable supply pressure to pneumatically actuated ball and butterfly valves on a bottling-plant process skid.
Regulated, water- and particulate-free air for the clamping and ejection cylinders on a CNC machining cell.
Size 400 with a 1/2 inch NPT port sits in the upper-middle of the GFR range; step down to 300 or up to 600 depending on the flow your line needs - we will check the flow curve against your demand before you order. The automatic drain on this unit expels collected condensate without daily attention; manual-drain and differential-pressure variants exist if you prefer a different routine. Filtration is the standard 40 um element, with 5 um (code W) available for finer protection. The round gauge reads psi (MPa and bar scales are alternatives), the thread is NPT with PT as standard and G to order, 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 number here. Send us your port size, working pressure and demand, and we will confirm sizing from the datasheet before you order.
The automatic drain on this GFR400 expels collected condensate without anyone opening the bowl, which suits unattended or high-humidity installations. The same size is also catalogued with a manual drain or a differential-pressure drain; note the regulator adjust range is 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain and 0.05-0.9 MPa (7-130 psi) with manual drain.
