The AirTAC GFR400C15AJF2G AirTAC Filter Regulator G1/2 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 AirTAC GFR400C15AJF2G is a size 400 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a 1/2 in G-thread port. This configuration carries an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and the standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). An embedded square gauge graduated in psi is fitted, and no mounting bracket is included with this code. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600, with options including a 5 um element (code W), manual or differential-pressure drain, G or NPT thread, gauge scales in MPa, psi or bar, and a mounting bracket. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing against your application - we will provide the datasheet 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.

Point-of-use conditioning on the 1/2 in air drop feeding a CNC machining centre: the 40 um element and automatic drain keep condensate and swarf-laden moisture out of the machine's solenoid valves and air cylinders, while the regulator holds a steady set pressure for clamping and tool-change actuation.
Mounted at the header take-off of a bottling or cartoning line, the GFR400C15AJF2G filters and regulates the supply to case-packing and sealing cylinders. The automatic drain handles condensate on a line that runs unattended across shifts, and the psi gauge lets technicians verify set pressure at a glance.
Installed on the 1/2 in branch of a plant maintenance workshop's compressed-air ring main, this filter regulator conditions the supply for impact wrenches, air ratchets and blow-off stations. The square psi gauge supports quick pressure checks, and the 40 um element protects general-purpose tools from water and pipe scale.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a 1/2 in port, one step up from the 300 series for higher-demand lines. Drain type is a real decision: automatic (this code) suits unattended or hard-to-reach installations, manual suits attended daily checks, and the differential-pressure default (blank) drains on a pressure drop. The 40 um element is standard; specify the W code if the downstream equipment needs 5 um filtration. Gauge scale is psi on this unit, with MPa and bar available as alternatives. PT is the standard thread; G (BSPP) and NPT are catalogue options to order - state the thread your pipework needs when ordering. This code (J) ships the unit without a mounting bracket; add the bracket option if you want panel or wall fixing.
Flow for the GFR400 is published as curves, not a single rated figure, so we cannot quote one number honestly. Tell us your application 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 GFR400 as performance curves rather than a single rated figure, so we do not quote one number out of context. Send us your application details - inlet pressure, set pressure and the air demand of the equipment - and we will confirm the sizing against the datasheet curves and provide the datasheet on request.
The A in the code GFR400C15AJF2G means the bowl drain ejects collected condensate automatically, with no manual intervention. It is the right choice for unattended installations, elevated mounting positions or any site where daily manual draining is impractical. The same GFR400 body is also available with a manual drain (code M) or the differential-pressure default (blank) if your maintenance routine suits those instead.
