The AirTAC GFR60025MF1TK AirTAC Filter Regulator 1in NPT 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 GFR60025MF1TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1 in NPT port for high-flow mains, a manual drain bowl in aluminium alloy, a 40 um standard filter element, an embedded square gauge scaled in MPa, a reverse/check valve, and a mounting bracket. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans 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, plus choices of drain type, filter grade (40 um standard, 5 um optional) and gauge scale. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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. 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.

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, filtering water and pipe-scale from the supply and holding a set pressure for the whole downstream distribution leg.
Feeding a bank of directional control valves on a packaging or assembly machine, where clean, moisture-reduced air at a stable set pressure keeps valve actuation consistent shift after shift.
Supplying air cylinders that divert, stop and index product on a conveyor line, with the regulator set to the pressure the cylinder circuit was designed for and the manual drain emptied during scheduled maintenance.
Choose the size and port step against the air demand of the line: this unit is the largest GFR frame at size 600 with a 1 in port, suited to high-flow mains where smaller frames would restrict supply. Drain type is a real decision: manual drain (this code) needs periodic bowl draining by an operator, while automatic and differential-pressure drains discharge condensate without attention. Filter grade is 40 um as standard here; specify the W option for 5 um where finer particulate removal is needed. The embedded square gauge is scaled in MPa, with psi or bar scales and an external round gauge available as options. Thread is NPT on this code, with PT as the catalogue standard and G (BSPP) also orderable. A mounting bracket is included.
Because flow for the GFR series is published as curves and not as a single rated number, 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. 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 rather than a single rated figure, so no one number can be quoted here. Tell us your line pressure, set pressure and air demand, and we will confirm the flow data from the datasheet and check the sizing for your application before you order.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl must be released by opening the drain by hand during routine checks. If you prefer unattended condensate removal, the GFR series is also available with automatic or differential-pressure drains - we can quote the equivalent code.
