The AirTAC GFR60025MLC2WTK AirTAC Filter Regulator NPT1 Low-Pressure 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025MLC2WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1 in NPT port, a 5 um filter element (the finer of the two published grades), a manual drain on the bowl, the low-pressure regulator type, a round pressure gauge reading in psi, and a built-in reverse/check valve. The size 600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge style and scale, standard or low-pressure regulation, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| 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.

Dropping from a large header into a cell of air-operated clamps and presses, this 1 in filter regulator cleans the supply to 5 um and holds the working pressure the cell was set up for, with the check valve holding downstream pressure if the main is interrupted.
Supplying the gate and stopper cylinders along a bottling conveyor, where the 5 um element keeps scale and pipe debris out of the directional valves and the manual drain lets maintenance bleed accumulated water at shift checks.
Feeding the positioners and actuators on a bank of process valves, where the low-pressure regulator type suits a lower working pressure, the psi gauge gives operators a familiar readout, and the aluminium bowl drains by hand during rounds.
Step up through sizes 200, 300, 400 and 600 until the port and flow capacity match your line; this unit is the size 600, 1 in NPT version, so it belongs at the head of a large supply main. Choose the drain to suit access: manual (as here) needs an operator to bleed the bowl, automatic drains itself, and differential-pressure drains on a set pressure drop. Pick 40 um for general protection or 5 um (this unit) for finer downstream cleanliness. Gauge style and scale are selectable - embedded square or external round, in MPa, psi or bar (this unit: round, psi). Thread is PT as standard with G and NPT as order options; a bracket is included, and the K code adds a reverse/check valve.
Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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, not as a single rated figure, so we do not quote a number. Send us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
The M code in GFR60025MLC2WTK specifies a manual drain: an operator opens the drain to bleed collected water from the bowl. The GFR family is also available with automatic drain (code A) or differential-pressure drain (blank), so choose whichever suits how often the installation is attended.
