The AirTAC GFR60025ALF2W AirTAC Filter Regulator PT1 1 in 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one unit cleans the air and holds a set downstream pressure. This configuration is the size 600 unit with a PT1 (1 in) PT-threaded port, the largest port in the G-series range. It carries a 5 um filter element (the tighter W grade, against the 40 um standard), an automatic drain that expels collected condensate without manual attention, a low-pressure regulator type, and an embedded square gauge reading in psi. The aluminium alloy bowl is specific to the 600 size, where the larger bowl suits higher-flow installations.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um elements, square or square-plus-round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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). |
| F | Gauge shape: Square. 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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.

Installed at a branch take-off on a factory compressed-air main, the unit filters water and scale from the supply and regulates pressure to a bank of air-operated valves, with the automatic drain handling condensate on a continuously running line.
Mounted at the inlet to a packaging conveyor's pneumatic circuit, the regulator holds a steady setting for the pusher and clamp cylinders while the 5 um element keeps fine particulate out of the directional valves.
Used on the air feed to a laboratory test rig, the low-pressure regulator type suits circuits that run at reduced settings, the psi gauge gives a direct readout for test records, and the automatic drain keeps the rig supplied with drained air.
Size the unit by the port step: the 600 size with its PT1 (1 in) port sits at the top of the range and suits lines where the largest G-series flow path is needed; step down to 300 or 400 if your piping is smaller. This unit has the automatic drain, which suits unattended duty; manual or differential-pressure drains are the alternatives in the same family. The 5 um element here is the tighter option for air that feeds sensitive valves and instruments; choose 40 um where coarser protection is enough. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included. Flow is published as curves, not a single rating, so 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. 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow and datasheet figures for this exact configuration on request.
The A in the code sets the automatic drain, which ejects collected condensate on its own instead of waiting for a manual bowl drain - useful on lines that run unattended. The W sets the 5 um filter element, the tighter grade against the 40 um standard, for air feeding sensitive downstream components.
