The AirTAC GFR60025ALC2TK AirTAC Filter Regulator NPT1 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 AirTAC GFR60025ALC2TK is a size-600 GFR filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This configuration is built around a 1 in NPT port, an automatic drain that expels collected condensate from the aluminium alloy bowl without manual intervention, a 40 um standard filter element, and a low-pressure regulator type. A round pressure gauge on a psi scale is fitted, and a reverse/check valve is included so downstream pressure is held if the supply side drops.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread choices of PT (standard), G and NPT, drain types (differential-pressure, automatic, manual), a 5 um element option, gauge scale choices, and a low-pressure regulator variant. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 a bank of quarter-turn pneumatic valves on a process skid with filtered, regulated air at low set pressure, with the check valve holding the actuator line if supply is interrupted.
Installed at the drop feeding a packaging hall's manifold, the automatic drain clears condensate from the aluminium bowl without daily attention and the psi gauge lets technicians verify line pressure at a glance.
Supplies the air cylinders that drive gates and diverters on a bottling conveyor, with the 40 um element stopping pipe scale and water from jamming the cylinder seals.
Size 600 is the largest step in the GFR range, and the 1 in NPT port here suits lines fed at high volume, so match the size and port step against the flow your circuit actually needs. Drain type matters: automatic drain suits unmanned or hard-to-reach installations, manual suits attended stations, and differential-pressure is the catalogue default. The 40 um element is the standard grade; a 5 um element (code W) is available where finer particulate removal is required. This unit is the low-pressure (L) regulator type, carries a round psi-scale gauge (MPa and bar scales are the alternatives), and includes the reverse/check valve (code K) and mounting bracket.
Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. The exact regulation range of the low-pressure type is not published in our sheet; we confirm it on request. PT is the standard thread; G and NPT are order options specified in the code.
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 as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and the flow your circuit needs, and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code sets an automatic drain: condensate collected in the aluminium alloy bowl is expelled on its own instead of waiting for a manual bleed. It suits unmanned compressor rooms, high drops and any station that is awkward to reach. Manual and differential-pressure drains remain available on other GFR configurations.
