The AirTAC GFR600-25ALC2T AirTAC Filter Regulator NPT 1 in 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 AirTAC GFR600-25ALC2T is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit is configured with a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filtration element, and the low-pressure regulator type for applications that work at reduced set pressures. Because it is size 600, the drain bowl is aluminium alloy. A round pressure gauge with a psi scale is fitted, a mounting bracket is included, and no reverse (check) valve is fitted.
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, and can be ordered with manual or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges in MPa, psi or bar scales, and PT, G (BSPP) or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

| 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. |

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.

On a spray-booth supply line, the filter stage strips water and pipe-scale that would otherwise blemish paint finishes, while the low-pressure regulator holds a reduced, steady set pressure at the spray guns. The automatic drain keeps condensate moving out of the aluminium bowl without an operator stopping by.
Case-sealing and stretch-wrapper machines run air cylinders continuously through a shift. A 1 in filter regulator at the machine drop conditions the whole supply in one unit: the 40 um element protects directional valves from particulate, and the regulated output keeps cylinder action consistent as the header pressure wanders.
Rinse heads and fill-station actuators on a bottling line need clean, dry-ish air at a controlled, moderate pressure. This low-pressure-type filter regulator filters the supply, holds the working pressure the station was set up for, and its round psi gauge lets technicians verify the set point at a glance during changeovers.
Step through the real choices before ordering. Size and port: 200, 300, 400 and 600 step up in port and flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone; this unit is the largest step at 1 in NPT. Drain: automatic (this unit) suits unattended installations, while manual and differential-pressure drains are available where you prefer controlled or pressure-differential dumping. Filter grade: 40 um is standard and suits general air prep; choose the 5 um W option where downstream equipment needs finer protection. Gauge: an embedded square gauge is the standard arrangement and an external round gauge is optional, in MPa, psi or bar scales; this unit carries the round gauge with a psi scale. Thread: PT is the standard thread, with G (BSPP) and NPT as catalogue options to order - this unit is ordered in NPT. A mounting bracket is included unless code J is specified.
One honest note on sizing: flow for this family is published as curves, not as a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the datasheet figures against your required flow 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 flow for the GFR family as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number here. Tell us your application and required flow, and we will confirm the datasheet figures for this 600-size, 1 in unit against your demand on request.
The A in the code means the drain bowl empties collected condensate automatically, which suits installations that run unattended. The family is also available with a manual drain (code M) or the differential-pressure drain (no code letter) if you prefer to dump condensate on demand. Drain choice affects the regulator's adjustment range, so confirm the exact figures for the configuration you want with us before ordering.
