The AirTAC GFR600C25MLF2W AirTAC Filter Regulator PT1 Low-Pressure 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 GFR600C25MLF2W is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built on a 1 in. PT port, carries the 5 um filtration element (code W, against the 40 um standard), drains manually, and is the low-pressure regulator type for circuits that run below standard line pressure. A square gauge scaled in psi is fitted, maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), the size 600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in. to 1 in., and options for thread (PT standard, G and NPT to order), drain type, filtration grade and gauge scale. Flow is published as curves rather than a single rating, so send us your application details and we will confirm the figures from the datasheet 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.

Filter and regulate the supply feeding a bottling hall's actuator manifolds. The 1 in. PT connection suits a header line, and the 5 um element helps keep water and grit out of downstream valves.
Supply filtered, regulated air to the stopper and pusher cylinders on a carton packing line, with the manual drain letting operators bleed collected water from the aluminium bowl at shift start.
Feed a leak-test or pneumatic test rig that runs below standard line pressure. The low-pressure regulator type and the square gauge scaled in psi suit US test-bench setups.
Choose the size and port against the air demand of your circuit: this unit is size 600 with a 1 in. PT port, the largest step in the range, and larger sizes carry more flow. Decide the drain next: this code has a manual drain, while automatic and differential-pressure versions suit unattended installations. The W in the code selects the 5 um element over the 40 um standard - pick 5 um where downstream valves, cylinders or instruments need finer protection. The square gauge here is scaled in psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available as order options, and a mounting bracket is included. Because AirTAC publishes flow as curves rather than a single rated figure, 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 curves rather than a single rated figure, so we do not quote a number. Send us your inlet pressure and air demand and we will confirm sizing against the datasheet curves before you order.
The M in the code specifies a manual drain: an operator opens the drain at the bottom of the aluminium bowl to release collected water. If you prefer automatic or differential-pressure draining, ask us about the equivalent GFR600 configuration.
