The AirTAC GFR600C25MC3TK 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 GFR600C25MC3TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for a 1 in port with NPT thread, has a manual drain on the bowl, a standard 40 um filter element, an external round pressure gauge with a bar scale, and a reverse/check valve fitted. The size 600 bowl is aluminium alloy, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with a choice of port sizes, PT/G/NPT threads, manual, automatic or differential-pressure drains, a 5 um (code W) element option, gauge scales in MPa, psi or bar, and a low-pressure regulator type. Flow is published as curves rather than a single rated figure, so ask us and we will 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 ahead of a CNC machining center's air-operated components: the 40 um element strips water and chips-laden particulate from the shop header while the regulator holds a steady setting for clamping and tool-change circuits.
Filtered and regulated air for the cylinders and air-operated valves on a carton-forming and sealing conveyor line, with the check valve holding the downstream setting if supply pressure dips and the manual drain for end-of-shift bowl bleeding.
Conditioning the air feed to spray guns in a finishing booth: particulate and water removal ahead of the gun, a fixed regulator setting for consistent atomisation pressure, and a bar-scale gauge the operator can read at a glance.
Step up or down through the GFR sizes (200/300/400/600) to match the port and the flow your line needs; this unit is the size 600, 1 in step. Drain choice matters: manual drain means an operator bleeds the bowl, while automatic and differential-pressure drains discharge condensate without attention. The standard element is 40 um; specify code W for the 5 um grade where downstream equipment needs finer filtration. Gauge scale can be MPa, psi or bar, and thread is PT as standard with G (BSPP) and NPT as order options; a bracket can be included or omitted (code J).
Because AirTAC publishes flow only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm sizing against the datasheet curves before you order.
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 as a single rated figure, so we do not state a flow number for this unit. Tell us your application and operating pressure and we will confirm the relevant datasheet curve figures on request before you order.
The M in the code specifies a manual drain: the bowl is bled by hand, which suits installations that are checked as part of a routine. If you would rather not rely on an operator, the same GFR600 size is available with an automatic drain (code A) or the default differential-pressure drain - the regulator adjustment range differs by drain type, with manual-drain versions adjusting from 0.05-0.9 MPa (7-130 psi).
