The AirTAC AirTAC GFR600C25MF2K Filter Regulator 1 in PT 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 GFR600C25MF2K is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in a single body. This size 600 unit is built for 1 in PT ports, and this configuration carries a manual drain, a 40 um standard filter element, an embedded square gauge reading in psi, and a reverse (check) valve. The 600-size bowl is aluminium alloy, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with manual, automatic or differential-pressure drains, a 5 um element (code W) in place of the standard 40 um, square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of PT. Flow 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.

Filtered, regulated air at a fixed set point keeps weld-clamp cylinders consistent through a shift; the manual drain is bled during planned cell maintenance and the check valve holds the setting if supply dips.
A single 1 in feed can serve a bottling conveyor's gate and stopper actuators; the 40 um element keeps water and debris out of the valves while the regulator holds the pressure the gate cylinders were set up with.
At the main 1 in drop feeding a row of assembly benches, this unit filters the shop air and sets one regulated pressure for the bench tools and fixtures, with the psi gauge giving operators a readable set point.
Start with the port: this unit is 1 in PT, the largest step in the GFR range, so size up to GFR600 when your line or compressor take-off is 1 in and downstream demand is high. Choose the drain to match how the unit is tended: this configuration is manual drain, which suits attended installations where an operator bleeds the bowl on a schedule; automatic or differential-pressure drains suit unattended lines. The 40 um element is the standard grade for general plant air; specify the 5 um W option where finer protection is needed. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are order options. PT is the standard thread, with G (BSPP) and NPT available to order, and a bracket is included.
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your line pressure, set pressure and expected air demand and we will confirm the sizing against the datasheet before you commit.
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 family as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet for this exact 1 in unit before you order.
The M in the code means the bowl is drained by hand, which suits installations that are checked on a schedule; with a manual drain the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). The same GFR600 body is available with an automatic drain (code A) or a differential-pressure drain (blank) if you need the bowl to clear itself.
