The AirTAC GFR600-25AC2T AirTAC Filter Regulator NPT1 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 PT1" ports, a automatic 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 GFR600-25AC2T is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body, with a 1 in NPT port for a large plant air main. This configuration carries an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, an aluminium alloy bowl (size 600 bowls are aluminium), and a round pressure gauge reading in psi. The standard regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi), with a maximum inlet (working) pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options including manual or differential-pressure drain, a 5 um element (code W), gauge scales in MPa, psi or bar, G (BSPP) or NPT thread in place of the PT standard, and a no-bracket variant. 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.

Installed on the 1 in branch feeding a paint booth area, it strips water and pipe scale from the main and holds a steady, set outlet pressure to the booth air controls, with the automatic drain handling condensate between shifts.
Mounted at the head of the pneumatic drop feeding conveyor diverters and bottle-clamp cylinders, it cleans the plant air and regulates it to the pressure the line was set up for, so actuators behave consistently through the shift.
Placed upstream of quarter-turn pneumatic valve actuators on a utility air header, it removes moisture and particulate before the positioner and solenoids and keeps actuator supply pressure at the set point the valve trim requires.
Start with the size and port: step up from 200 to 600 as your line volume grows, and match the port to your main - here that is 1 in NPT (PT is the catalogue standard; G and NPT are options you order). Choose the drain to suit access: automatic (this unit) for unattended duty, manual where an operator drains on a schedule, or the differential-pressure default. Pick the filter grade - 40 um standard for general plant air, 5 um (code W) where finer protection matters - and the gauge scale (MPa, psi or bar) to match your other instruments. A bracket is included on this unit.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not state a flow number here. Tell us your line pressure and demand and we will confirm the relevant datasheet curve figures for this unit on request before you order.
The drain decides how condensate leaves the bowl. This unit has an automatic drain, which discharges collected water without operator attention - useful on inaccessible or continuously running installations. The alternatives are the differential-pressure default and a manual drain (code M), which suits attended installations on a drain schedule. All three share the same 0.15-0.9 MPa (20-130 psi) regulation range on this standard type.
