The AirTAC GFR60025ALC2WTK AirTAC Filter Regulator 1 in NPT 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 GFR60025ALC2WTK 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 for a 1 in NPT port, carries the W fine filtration grade (5 um instead of the standard 40 um), and drains its bowl automatically, so collected condensate is expelled without manual attention. It is the low-pressure (L) type, intended for circuits that hold a lower set pressure than a standard unit, and it ships with a reverse/check valve (K) fitted, an external round gauge on the psi scale, and a mounting bracket included. The size 600 bowl is aluminium alloy, and the maximum working (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 is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, gauge type and scale, and reverse/check valve. Flow 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.

| 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. |

| 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding the low-set-pressure section of a packaging machine's air network, where the low-pressure (L) regulator type holds a reduced setting and the automatic drain keeps condensate off the machine without daily attention.
Conditioning and regulating the compressed air that strokes large pneumatically actuated valves on a plant floor, with 5 um filtration protecting the positioner and pilot hardware and the reverse/check valve holding the circuit on supply loss.
Supplying regulated air to conveyor stoppers, lifts and diverters on a high-throughput line, where the 1 in NPT port matches the main drop leg and the round psi gauge lets technicians verify the set point at a glance.
Start with the port and size: this unit steps up to the 600 frame with a 1 in NPT connection, the largest in the GFR range, so match it to your line size and required flow, stepping up a size if the curve shows too much pressure drop. Choose the drain to suit access: automatic (this unit) suits unmanned or hard-to-reach installations, manual suits attended stations, and differential-pressure drain is the default. Choose the filter grade: 40 um is standard for general protection, while the 5 um (W) grade fitted here suits finer downstream equipment. Set the gauge type and scale - this unit has an external round gauge on psi; embedded square gauges and MPa/bar scales are alternatives. Thread is PT as standard with G and NPT as order options; a bracket is included unless the J (no bracket) code is specified.
Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The exact adjustment range of the low-pressure (L) regulator type is also confirmed on request.
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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request.
The A in the code specifies an automatic drain, which expels collected condensate from the aluminium bowl without manual attention - useful for unmanned or hard-to-reach installations. Manual drain and the default differential-pressure drain are available as order options if you prefer.
