The AirTAC GFR60025MC1WT AirTAC Filter Regulator 1 in NPT 5 um 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 GFR60025MC1WT 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 with a 1 in NPT port, a 5 um filtering element (the finer of the two catalogue grades), a manual drain on the bowl, and a round pressure gauge with an MPa scale. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). At this 600 size the bowl is aluminium alloy, and the unit is rated for -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, and square or round gauges with MPa, psi or bar scales. 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Installed at the take-off from a factory compressed-air ring main, it filters water and particles from the supply and holds a set downstream pressure for the whole workshop section served by the 1 in line.
Mounted ahead of the valve stack on a conveyor line driven by pneumatic cylinders, it conditions the air and lets maintenance set a stable operating pressure for consistent cylinder stroke behaviour.
Fitted on the air feed to a CNC machine's clamping and actuation circuit, the 5 um element protects sensitive valves from particulate while the regulator sets the pressure the fixture designer specified.
Start with the port and size: this unit is the largest step in the range, size 600 with a 1 in NPT port, so match it against the pipe diameter and the flow your line needs. Choose the drain type deliberately: this version has a manual drain, which means an operator drains the bowl on a routine you set; automatic or differential-pressure drains suit installations that cannot be attended regularly. The 5 um element fitted here is the finer option; the 40 um grade is the standard choice where only coarse protection is needed. The gauge fitted is a round external type on an MPa scale; square embedded gauges and psi or bar scales are alternatives. NPT is the thread ordered here; PT is the catalogue standard and G is also available. A mounting bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm 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 GFR flow as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your line pressure and the flow your application needs and we will confirm the correct size from the datasheet on request before you order.
The M in the code selects the manual drain: condensate collected in the aluminium bowl is released by operating the drain by hand on a schedule you set. If the installation cannot be attended regularly, the same size is available with an automatic or a differential-pressure drain instead.
