The AirTAC GFR400C15AJC2 AirTAC Filter Regulator PT1/2, Auto Drain 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 GFR400C15AJC2 is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single 1/2-inch (PT1/2) unit. This configuration has an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, a standard-range regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), and a round pressure gauge reading in psi. It is supplied without a mounting bracket and without a reverse (check) valve. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, a 5 um (code W) element option, gauge style and scale choices, G or NPT thread options, and bracket choices. At size 400 the bowl is PC (polycarbonate). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clamps, tool-change cylinders and blow-off nozzles on a CNC machining centre: the 40 um element strips water and swarf-carried grit before it reaches valves, while the regulator holds a steady setpoint to the fixtures and the psi gauge lets setters verify it at a glance.
Supplying carton sealers, case packers and bagging heads on a packaging line, where the automatic drain keeps condensate out of the cylinders on lines that run unattended across shifts and the regulator keeps actuator timing consistent.
Conditioning shop air feeding lab analysers, sample-handling actuators and pneumatic stirrers, where a stable regulated supply and a visible psi reading protect sensitive instruments from pressure drift and particulate.
Choose the size and port against the flow your line needs: 400 is the larger frame and this unit carries a PT1/2 port; if your demand sits near the top of a smaller frame's curve, step up rather than downsize. Decide the drain first - automatic (this unit) suits points that are hard to reach or run unattended, manual suits attended stations, and the differential-pressure default drains only as the element loads up. Pick 40 um for general air or the 5 um W code for finer protection downstream. This unit is fitted with a round psi gauge; the embedded square gauge and MPa or bar scales are alternatives, and G (BSPP) or NPT threads can be ordered instead of the PT standard. Brackets are optional (this code omits one). Flow is published as curves, not a single rating - send us your air demand and we will confirm sizing against the datasheet 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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow and sizing from the datasheet on request.
This code carries an automatic drain, which ejects collected condensate on its own - useful for unattended or hard-to-reach installations. The GFR400 is also available with a manual drain or the differential-pressure default, and the filter grade can be stepped from the standard 40 um to 5 um with code W.
