The AirTAC AirTAC GFR600-25ALC2W Filter Regulator 1 in PT, 5 um 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 GFR600-25ALC2W is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1 in PT port, a 5 um filter element (the finer of the two published grades), an automatic drain that discharges collected condensate without manual attention, and a low-pressure regulator type fitted with an external round gauge scaled in psi. The size-600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is offered with a choice of drain type, filter grade, gauge style and scale, and PT, G or NPT thread. Published flow data appears as curves rather than a single rating, so ask us to confirm flow or any datasheet figure 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. |
| (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.

Supplies filtered, regulated air to clamping fixtures on a CNC machining cell, where the low-pressure regulator type holds a lower set pressure and the 5 um element keeps fine particulate out of the clamp cylinders.
Feeds clean, pressure-controlled air to bench-top test rigs and lab pneumatic circuits, with the automatic drain clearing condensate during unattended runs and the psi round gauge giving a direct pressure readout.
Conditions the air feeding conveyor stopper and diverting cylinders on a packaging line, combining water and particle removal with regulation in one body at the 1 in port size the main line takes.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 1 in PT port, the largest step in the GFR range. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Beyond size, the real decodable choices are drain type (this unit has an automatic drain; manual and differential-pressure drains are the alternatives), filter grade (this unit carries the 5 um W element instead of the 40 um standard), gauge style and scale (this unit has an external round gauge in psi; an embedded square gauge in MPa, psi or bar is the other route), thread (PT is standard here; G and NPT are order options), and the low-pressure regulator type selected by the L code. The exact regulation range of the low-pressure type is not published in our sheet, so confirm it with us for your set pressure.
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 curves, not as a single rated figure, so we do not quote a flow number. Send us your application's air demand and we will confirm the correct size and read the relevant curve from the datasheet for you before you order.
The L code selects the low-pressure regulator type rather than the standard type, for circuits set at lower pressures. The exact regulation range of the low-pressure type is not published in our sheet, so confirm your set pressure with us and we will verify it against the datasheet. The rest of the code decodes as: size 600, 1 in PT port, automatic drain, 5 um element, external round gauge in psi, no reverse valve, bracket included.
