The AirTAC GFR60025AF2GK AirTAC Filter Regulator G1, 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" 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 GFR60025AF2GK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1 (1 in, G/BSPP) port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure when the supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a 5 um element (code W), manual or differential-pressure drain, gauge scale in MPa, psi or bar, and PT or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Clean, regulated air for tool changers, clamps and spindle-integrated pneumatics on a machining centre, with the check valve holding set pressure through supply dips.
Filtered, regulated air for case sealers, labelers and palletizer grippers on a high-throughput packaging line, with automatic drain keeping condensate off the actuators.
Conditioned air feeding pneumatic quarter-turn actuators and positioners on a process skid, where stable regulated pressure keeps valve stroking consistent.
Step up or down through sizes 200 to 600 to match the port and flow path your line needs; this unit is the size 600, 1 in step. Choose the drain to suit access: automatic (this unit) for unattended duty, manual where you want controlled blowdown, or differential-pressure as the default. Pick 40 um for general air preparation or 5 um (code W) for finer protection. The square gauge is fitted here in psi; MPa and bar scales, and an external round gauge, are order options. Thread is G (BSPP) as coded, with PT and NPT available to order, and the mounting bracket is included. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 number, so we do not quote a figure. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
The A in the code means the bowl drains itself automatically, which suits unattended or hard-to-reach installations. Manual (code M) and differential-pressure (blank) drain versions are available in the same family if you prefer controlled or default drainage.
