The AirTAC GFR40015AJF2 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 PT1/2" ports, a automatic 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 GFR40015AJF2 is a size 400 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. On this configuration the port is PT1/2 (1/2 in PT thread, with G and NPT available as order options), the drain is automatic, so collected condensate is expelled without manual attention, and the filtration grade is the 40 um standard element. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the fitted square gauge reads in psi so operators can set and monitor line pressure directly. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl is fitted on this size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with code W), gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order). Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so we 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.

Point-of-use conditioning for the 1/2 in air line feeding clamps, tool-change cylinders and pneumatic actuators on a CNC machining centre, with the automatic drain keeping condensate out of the circuit between shifts.
Filtered and regulated air for the diverters, pushers and sealing cylinders along a carton packaging conveyor, where the psi square gauge lets line staff set and verify the pressure the actuators were designed for.
Conditioning a 1/2 in branch drop in a factory compressed-air ring main, delivering clean, pressure-controlled air to downstream valves and cylinders while the automatic drain handles accumulated water.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with a PT1/2 (1/2 in) port, and the GFR range steps through sizes 200, 300, 400 and 600 as port and capacity rise. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. On this code the drain is automatic (code A), which suits unattended duty; manual (M) and differential-pressure (blank) drains are available on other variants. The filter grade is the 40 um standard element; specify code W for the 5 um grade where finer filtration is needed. The fitted square gauge here reads in psi (code F2); MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and code J means this unit is supplied without a mounting bracket (omit J where a bracket is required).
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 in the catalogue, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this size 400, PT1/2 unit on request before you order.
Code A in GFR40015AJF2 means the bowl drain expels collected condensate automatically, which suits installations that run unattended. The family also offers a manual drain (code M) and a differential-pressure drain (blank code) if you prefer operator-initiated or pressure-differential draining.
