The AirTAC GFR600C25MF2T AirTAC Filter Regulator 1 in 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C25MF2T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with a 1 in NPT port, a 40 um standard filter element, a manual drain on the bowl, and an embedded square gauge scaled in psi. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), with a maximum inlet (working) pressure of 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um (W) filter grade alternative, gauge scale choices, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application on request.

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 0.15 - 0.9 MPa (20 - 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.

Point-of-use conditioning at large paint-booth air drops: the 40 um element strips water and pipe scale before the regulator sets a stable supply pressure to spray equipment, and the manual drain lets maintenance staff clear accumulated condensate during shift checks.
Feeding the clamping and tool-change circuits of a CNC machining centre: the 1 in NPT port suits high-demand main lines, the square psi gauge gives operators a direct pressure readout at the machine, and the regulator holds the set pressure for consistent clamp force.
Conditioning the main air supply to a bottling or packaging line where cylinders, diverters and grippers run continuously: the filter-regulator cleans the air and sets line pressure in one unit, with the manual drain emptied as part of the line's daily housekeeping routine.
Start with the port and size step: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, so match it against the air demand of the circuit - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Drain type is a real choice: manual (as fitted here) requires periodic draining by hand, while automatic and differential-pressure drains discharge condensate without intervention; note the regulation range differs by drain type, with manual-drain units covering 0.05-0.9 MPa (7-130 psi). Filter grade is 40 um standard, with a 5 um element available under code W if finer filtration is needed. The gauge here is the embedded square type scaled in psi; MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this unit, with PT as the catalogue standard and G (BSPP) also orderable; a mounting bracket is included.
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 the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the relevant flow and datasheet figures on request so you can size the unit correctly.
This configuration carries code M, meaning the bowl is drained by hand at intervals. The GFR family also offers an automatic drain (code A) and a differential-pressure drain (blank, the default) that discharge condensate without manual attention; note that the regulator adjustment range is 0.05-0.9 MPa (7-130 psi) with a manual drain and 0.15-0.9 MPa (20-130 psi) with the automatic or differential-pressure drain.
