The AirTAC GFR60025ALC2G AirTAC Filter Regulator G1 Low-Pressure 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 GFR60025ALC2G is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is built around a G1 (1 inch) port with G thread, and its configuration is fully decodable from the code: A = automatic drain, so condensate is expelled from the aluminium alloy bowl without manual attention; L = low-pressure regulator type, intended where the working pressure sits below the standard regulator range; C2 = an external round gauge fitted with a psi scale; and the trailing G confirms the G (BSPP) thread option. Filtration is the 40 um standard grade, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port sizes stepping from 1/8 in up to 1 in, a choice of automatic, manual or differential-pressure drains, 40 um or 5 um (W) filtration, gauge or no-gauge builds with MPa, psi or bar scales, 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Where a big production hall feeds a 1 in distribution leg off the main ring, this G1 filter regulator cleans the supply of water and pipe scale and holds the downstream pressure for the whole drop, with the automatic drain keeping the aluminium bowl clear of condensate through long shifts.
Conveyor diverters, gate cylinders and stopper units on a packaging or bottling line often run off a single large-bore feed. This unit filters that feed to 40 um and regulates it at low pressure for the actuators, with the round psi gauge giving operators a visible setpoint at the panel.
A commercial-vehicle service bay running impact tools, tyre cages and test rigs from a workshop compressor benefits from one filtered, regulated drop. The 1 in port serves high-draw bays, the automatic drain copes with the moisture a big compressor generates, and the psi gauge lets technicians verify supply pressure before brake or tyre work.
Start with the size and port: this is the largest step in the range, size 600 with a G1 (1 in) port, chosen when the air demand at the point of use calls for the top of the GFR flow envelope. Because flow is published as curves rather than one rated number, send us your demand and we will confirm the fit against the datasheet before you order. The remaining choices are all real, decodable options: drain type (this unit is automatic; manual and differential-pressure are the alternatives), filter grade (40 um standard here, 5 um with code W where finer filtration is needed), gauge presence and scale (this build carries an external round gauge reading psi; embedded square gauges and MPa or bar scales are the other routes), and thread (G here, with PT as the standard and NPT orderable). A mounting bracket is included with this unit. Note that this is the L low-pressure regulator type; its exact adjustment range is not published in the catalogue, so confirm it with us for your setpoint.
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-series flow as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet on request before you order.
The A in the code sets the automatic drain: condensate collected in the bowl is expelled without anyone opening it, which suits unattended or high-moisture installations. The GFR family also offers a manual drain (code M) for periodic attention and a differential-pressure drain (blank code) as the standard; all three are orderable choices on the same size 600 body.
