The AirTAC GFR600C25MJC1WTK 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 GFR600C25MJC1WTK is a size-600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is built around a 1 in NPT port for high-flow main lines, with the fine 5 um filter element (code W) instead of the standard 40 um, a manual drain on the bowl, a round external pressure gauge scaled in MPa, and a built-in check (reverse) valve that holds downstream pressure when the upstream supply is lost. It ships without a mounting bracket, and the size-600 bowl is aluminium alloy. Regulation range with manual drain is 0.05-0.9 MPa (7-130 psi), max inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the family you can order differential-pressure, automatic or manual drains, a 40 um or 5 um element, square or round gauges with MPa, psi or bar scales, a low-pressure regulator type, a check valve, PT, G or NPT threads, and with or without a bracket. Flow for this size is published as curves rather than a single rated 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 0.15 - 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.

Installed on the 1 in main drop after a plant air compressor and receiver, it removes water and fine particulate from the whole supply and holds a set regulated pressure for the downstream distribution manifold, with the check valve keeping the line pressurised during compressor unload.
Feeding the cylinder and actuator banks on a bottling or packaging conveyor run, the 5 um element protects directional valves from fine contamination while the regulator holds a steady working pressure for consistent gripper and pusher motion.
Mounted ahead of a CNC machining cell's pneumatic circuits - clamps, tool-change cylinders and air blasts - it delivers filtered, regulated air at a stable setpoint, with the MPa-scaled round gauge giving the operator a clear visual reference at the machine.
Size 600 with a 1 in port is the largest step in the GFR range, so start there when your line flow demands the biggest ports; smaller sizes (200/300/400) step down through 1/8 in to 3/4 in. Drain is a real choice: manual (this unit, and it widens the regulation range to 0.05-0.9 MPa), automatic, or the differential-pressure default - pick automatic if nobody will drain the bowl routinely. This unit carries the 5 um element (code W); the 40 um standard element suits general upstream protection if you do not need fine filtration. The round external gauge here reads in MPa; square embedded gauges and psi or bar scales are orderable. Thread is NPT on this unit - PT is the catalogue standard and G (BSPP) is also an option - and note the bowl on size 600 is aluminium alloy. No bracket is fitted; bracketed versions exist. Because flow is published as curves rather than one 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. 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 GFR600 as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and line conditions and we will confirm the flow data from the datasheet and check the sizing for you before you order.
The M code in the model means the bowl is drained by hand rather than automatically or by differential pressure. Manual-drain units also carry the wider 0.05-0.9 MPa (7-130 psi) regulation range. Choose the automatic-drain version instead if the unit will be installed where nobody can drain the bowl regularly.
