The AirTAC GFR60025MLC1WTK 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 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 GFR60025MLC1WTK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for a 1 in NPT port. This configuration carries the W 5 um filter element for finer protection downstream, a manual drain on the aluminium alloy bowl, the low-pressure regulator type, a round pressure gauge scaled in MPa, a fitted reverse (check) valve and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing from the datasheet 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.
| 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. |
| 1 | Gauge scale: MPa. 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.

Packaging machines with large air cylinders or clamp actuators that run below standard line pressure get filtered air and a stable, lower set pressure from this 1 in filter regulator, with the fitted reverse valve blocking backflow in the supply circuit.
In water-treatment or material-handling plants, quarter-turn actuators on gates and dampers often need a reduced, steady supply; this low-pressure type filter regulator conditions the 1 in main and sets the working pressure for the actuator loop.
Conveyor hold-down and air-cushion sections run on gentle, low-pressure air; the 5 um element keeps water and particles out of the distribution manifold, and the manual drain lets operators bleed accumulated condensate during shift checks.
The GFR family gives you one decodable choice per position. Step through sizes 200, 300, 400 and 600 - each with its own port from 1/8 to 1 in - to match the air demand of the line; this unit is the largest size, 1 in NPT. Choose the drain: manual as fitted here, suited to attended maintenance rounds, or automatic, or the differential-pressure default. Choose the filter grade: 40 um standard or 5 um with the W code, as on this unit, where finer filtration is needed. Gauge options are the embedded square gauge or an external round gauge, scaled in MPa, psi or bar; this unit carries a round MPa gauge. The K code adds a reverse (check) valve, and the trailing thread letter selects PT (the standard), G (BSPP) or T (NPT). 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 G-series flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the GFR600 datasheet before you order.
The L code in GFR60025MLC1WTK selects the low-pressure regulator type, intended for set points below the standard type's range. The exact adjustment range for the low-pressure version is not published in our data, so we confirm it on request. For reference, the standard GFR type with a manual drain adjusts from 0.05 to 0.9 MPa (7-130 psi).
