The AirTAC GFR60025MLC3T 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 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 GFR60025MLC3T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 1 in NPT port, a manual-drain bowl in aluminium alloy, a 40 um filter element, and the low-pressure regulator type. A round gauge scaled in bar is fitted and a mounting bracket is included. 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. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices of differential-pressure, automatic or manual, a 40 um standard or 5 um (code W) element, and G or NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 filtered, low-pressure regulated air to hold-down clamps on a CNC router, with the manual drain bled at shift start to clear accumulated water.
Conditions the air feeding low-pressure jets and cylinders on a textile line, protecting components from water and particulate while holding a gentle set pressure.
Regulates building compressed air down to the low pressures lab apparatus needs, with the 40 um element stopping pipe scale from reaching sensitive instruments.
Size and port set the air capacity: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range - match the port to your supply line and required flow. The manual drain needs periodic bleeding by hand; automatic and differential-pressure drains are available on other variants of the same unit. The 40 um element is the standard grade; a 5 um element (code W) is offered where finer filtration is needed. Thread here is NPT; PT is the standard and G (BSPP) is an order option. A round bar-scale gauge is fitted and a bracket is included. This is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us against your set pressure before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing from the datasheet.
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.
Flow for the GFR600 is published as curves, not a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and expected air demand and we will confirm from the AirTAC datasheet whether this 1 in NPT unit is correctly sized for your application.
The M stands for a manual drain: someone must open it periodically to release the water collected in the aluminium bowl. If the unit will sit where it cannot be attended, ask us about the automatic (A) or differential-pressure drain variants of the same GFR600 unit.
