The AirTAC GFR60025ALF2WG AirTAC Filter Regulator G1 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60025ALF2WG is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This size 600 unit is built with a G1 (1 in) port in G thread, a 5 um filter element (code W, finer than the 40 um standard), an automatic drain that expels collected condensate without manual intervention, and the low-pressure regulator type for applications regulated below standard ranges. An embedded square gauge scaled in psi is fitted so the set pressure is visible at the unit, and the aluminium alloy bowl suits this largest frame size. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options across drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Weaving sheds run compressed air to jet nozzles and loom cylinders from a shared main. A GFR600 filter regulator at the loom header strips water and fine particulate before the jets and holds a steady, lower regulated pressure so pick performance stays consistent through the shift.
Spray guns and air-driven fluid pumps in a finishing line need air with condensed water and 5 um-level particles removed, delivered at a pressure the operator sets and reads locally. This filter regulator mounted at the booth manifold does both jobs in one body, with the psi gauge in view.
Stopper cylinders, pushers and gate actuators along a packaging conveyor need clean, regulated air to seat consistently without creeping. Feeding the valve manifold through this unit filters the line air, drains condensate automatically and lets the setter dial the pressure the mechanics designed for.
Start with the port step: size 600 with a G1 (1 in) port is the largest GFR frame, so match it to the line volume your circuit actually passes rather than oversizing on pipe alone. This code carries the automatic drain, which suits unattended duty; choose manual drain where you want controlled discharge, or the differential-pressure default where periodic blowdown is acceptable. The 5 um element (code W) is the right pick when downstream valves and instruments need finer air than the 40 um standard element delivers. The gauge here is the embedded square type scaled in psi; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this unit - PT is the catalogue standard and NPT is also an order option, so confirm which your pipework takes. A mounting bracket is included with this configuration. On sizing: flow is published as curves, not a single rated figure, so send us your application conditions and we will confirm the datasheet numbers before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves against inlet pressure, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your operating pressure and the air your circuit needs, and we will confirm the datasheet curve and the right size for the job on request.
The A in the code selects the automatic drain, which discharges collected condensate from the aluminium bowl without anyone opening it - useful on lines that run unattended. The family also offers manual drain (code M) for controlled discharge and differential-pressure drain (blank) as the default. Drain choice does not change the filtration or regulation function.
