The AirTAC GFR600-25MLC1WT 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 GFR600-25MLC1WT is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit has 1 in NPT ports, a 5 um filter element (the finer W grade, versus the standard 40 um), a manual-drain bowl in aluminium alloy, the low-pressure regulator type, and a round pressure gauge reading in MPa. A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade, gauge style and scale. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. |
| 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. |
| (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, regulated air to the pneumatic cylinders and actuators on a carton-forming and sealing line, with the 5 um element protecting downstream valves from water and debris.
Supplies the low-pressure circuits that drive conveyor stoppers, gates and diverters, with the manual drain letting maintenance purge accumulated condensate at shift checks.
Prepares the air for pneumatic clamps and workholding fixtures in a machining cell, with the MPa gauge visible so operators can verify the set pressure at a glance.
Choose the size and port step against the flow your line needs: 600 is the largest G-series size, and this unit steps to 1 in NPT (PT is the standard thread; G and NPT are order options). Drain choice matters: manual drain means someone opens the bowl to discharge collected water, while automatic and differential-pressure drains discharge on their own. The filter grade here is 5 um; 40 um is the standard grade if finer filtration is not required. The round gauge reads MPa; the embedded square gauge and psi or bar scales are alternatives. A bracket is included. This is the low-pressure regulator type, and its exact regulation range is not published, so we confirm it on request. Because flow is published as curves rather than a single rating, ask us to check sizing against your application before ordering.
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.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is emptied by hand. Choose it where bowls are checked regularly; choose automatic or differential-pressure drain if you want discharge without operator action. This unit also carries the 5 um W-grade element and a round MPa gauge.
