The AirTAC GFR60025ALC2WK AirTAC Filter Regulator PT1 1 in 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 1 in PT1 ported unit conditions the air and holds the downstream pressure setting. This configuration, GFR60025ALC2WK, is the size 600 low-pressure type fitted with a 5 um filter element (W code), an automatic drain that bleeds collected condensate without manual attention, an external round gauge scaled in psi, a reverse/check valve to hold the downstream circuit, and a mounting bracket. The aluminium alloy bowl is standard at this size.
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, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures against 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. |

| 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. |
| (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.

Feeds booth exhaust controls, coating guns and actuated dampers on a paint line, where the 5 um element keeps fine contamination out of gun air circuits and the regulator holds a steady low setting for consistent coating work.
Supplies the cylinders and air grippers that index, fill and seal containers on a packaging conveyor. The automatic drain clears condensate from high-throughput compressed air without operator attention, and the check valve holds the circuit during brief upstream dips.
Provides filtered, regulated air to the clamp cylinders that hold workpieces on a CNC fixture or welding jig, where a stable low-pressure setting protects the clamping sequence and the psi gauge gives operators a direct reading.
Start with the port and size step: GFR600 is the largest frame in the family, here with a 1 in PT1 connection, and the right choice is the size whose flow curve covers your demand with margin - we can check that against the datasheet curves on request. Choose the drain to match access: automatic (as fitted here) suits units mounted where condensate is hard to reach or checks are infrequent; manual suits attended installations; differential-pressure drain is the default. The 5 um element (W) is the finer option where downstream valves and instruments need cleaner air than the 40 um standard element delivers.
Further decodable choices on this unit: the low-pressure type (L) regulator variant - its exact regulated range is not published in the material we hold, so confirm it with us; the round external gauge in psi (square embedded gauges and MPa/psi/bar scales are the alternatives); the fitted reverse/check valve (K) for circuits that must hold pressure; PT as the standard thread with G and NPT available to order; and the included mounting bracket.
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 GFR600 series as curves rather than a single rated figure, so we do not quote one number. Send us your operating pressure and air demand and we will confirm the sizing from the datasheet curves before you order.
The A code in GFR60025ALC2WK means the bowl drains collected condensate automatically instead of waiting for a manual bleed. Choose it for the 1 in size 600 frame when the unit is mounted high, in an enclosure, or on a line that is not checked daily; manual and differential-pressure drain versions of the same filter regulator are also available.
