The AirTAC GFR60025ALC2WG 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 AirTAC GFR60025ALC2WG is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G1 (1 in) port, a 5 um filter element (the finer of the two published grades), an automatic drain that discharges collected condensate without manual attention, and the low-pressure regulator type for circuits that sit below standard regulation ranges. It is fitted with an external round gauge on the psi scale, the aluminium alloy bowl used on 600-size bowls, a mounting bracket, and no reverse/check valve. 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 from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, standard or low-pressure regulation, gauge scale options, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Fixture clamps and swing cylinders on a CNC machining cell that hold workpieces at reduced circuit pressure get filtered, regulated air from this unit, with the psi-scale round gauge letting setters read and lock the clamp setting directly.
A carton-sealing or bagging line's sealing bars and guide cylinders draw air through this filter regulator: the 5 um element protects the sealing valves from particulate and water carryover while the low-pressure regulator holds the gentle pressure those actuators need.
Analytical instruments, sample pumps and pneumatic stirrers on a lab air ring main need clean, steady, lower-pressure air - the 5 um filtration, automatic drain and round psi gauge make this a tidy wall-mounted take-off point, with the included bracket for panel fixing.
Step up through the GFR sizes (200, 300, 400, 600) until the port and flow capacity match your line - this 600 unit sits at the top with a G1 (1 in) port. Because flow is published as curves and not a single rating, send us your air demand and we will confirm sizing against the datasheet before you order. On this code the drain is automatic (A), which suits unattended installations; manual (M) and differential-pressure (blank) drains are the alternatives if you prefer scheduled or load-dependent drainage. The W code selects the 5 um element over the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need cleaner air. The C2 gauge code gives an external round gauge reading in psi (MPa and bar scales are the other options, and the embedded square gauge is the standard fitting). Thread here is G (BSPP); PT is the catalogue standard and NPT is also orderable. A mounting bracket is included on this configuration.
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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote a number such as l/min or SCFM. Tell us your air demand and line pressure and we will confirm the correct sizing from the datasheet on request before you order.
GFR is the filter-regulator family, 600 is the size, 25 is the 1 in port, G is the G (BSPP) thread (PT is the standard, NPT is also orderable), A is the automatic drain, L is the low-pressure regulator type, C is the external round gauge, 2 is the psi gauge scale, W is the 5 um filter element, and the absence of a K code means no reverse/check valve is fitted. A mounting bracket is included.
