The AirTAC GFR600C25MLF2 AirTAC Filter Regulator 1 in PT, 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 GFR600C25MLF2 is a genuine AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit has a PT1 (1 in) PT thread, the standard 40 um filter element, and a manual drain (code M), so condensate is released by hand when you service the bowl. It is the low-pressure regulator type, and it comes with an embedded square gauge reading in psi; an external round gauge is available as an option. The metal bowl on this 600 size is aluminium alloy, and a mounting bracket is included. No reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filter elements, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request before you order.

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.

Hold-down clamps and vacuum-assist fixtures on a woodworking router often run at reduced pressure. This unit filters the shop air and regulates it down in one body, with the psi gauge letting the operator set and check the clamp pressure at a glance.
Low-pressure spray and coating lines need clean, moisture-free air held at a gentle, stable setting. The 40 um element catches water and particulate ahead of the gun, while the low-pressure regulator type suits applications that never need line pressure.
Sealing jaws, pushers and diverters on a packaging conveyor typically run from a filtered, regulated take-off near the machine. A 1 in PT connection feeds the main drop, the manual drain fits a shift-start maintenance routine, and the psi gauge keeps the setting visible.
Size 600 with a 1 in port sits at the top of the GFR range, so step up or down through 200/300/400/600 against the flow your line needs; the port steps are 06 (1/8 in) through 25 (1 in). Drain choice matters here: this unit is manual (M), while automatic (A) and differential-pressure (blank) versions drain with less attention - pick manual if servicing is already part of the routine. The 40 um element is the standard grade; specify W for 5 um where finer filtration is needed. The fitted square gauge reads psi; MPa and bar scales are alternatives. PT thread is standard, with G and NPT as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated number, and the exact regulation range for the low-pressure type is not listed in the standard table. Ask us to confirm both 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 series as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote honestly. Tell us your application and we will confirm the curve data and sizing on request before you order.
M is the manual drain: condensate collects in the aluminium alloy bowl and you release it by hand during service. AirTAC also offers automatic drain (code A) and differential-pressure drain (no code) versions of the same filter regulator if you would rather not rely on manual draining.
