The AirTAC GFR600C25AJF2W AirTAC Filter Regulator PT1 5 um 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 GFR600C25AJF2W is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is specified with a PT1 (1 in) PT-thread port, a 5 um filter element (the finer of the two catalogue grades), and an automatic drain that bleeds collected condensate from the bowl without manual attention. At size 600 the bowl is aluminium alloy. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the fitted embedded square gauge reads in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is included and no reverse (check) valve is fitted; a bracket is available as an option.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with a 40 um or 5 um element, differential-pressure, automatic or manual drain, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and with or without a bracket. Flow figures are published as curves rather than a single rating, so ask us to 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.

Fitted on the 1 in main air drop feeding a CNC machining centre, it removes water and fine particulate from the shop air and holds a steady regulated pressure to the machine's pneumatic valves and clamps, with the psi gauge giving operators a direct setpoint readout.
Installed at the air drop ahead of a paint booth's supply header, the 5 um element strips fine contamination and the automatic drain handles condensate on a line that runs unattended across shifts, keeping the regulated feed to spray equipment stable.
Mounted on the main feed to a bottling line's conveyor and gating cylinders, it filters the compressed air and regulates it to the pressure the cylinder and valve sizing was designed around, with the 1 in port matching the line's main header.
Sizing a GFR unit starts with the port and size step: this configuration is size 600 with a PT1 (1 in) port, the largest step in the family, suited to lines fed at 3/4 in to 1 in. Choose the drain to match the installation: automatic drain (as fitted here) suits unattended or hard-to-reach positions, manual drain suits supervised points, and the differential-pressure default drains only when the pressure differential calls for it. The 5 um element fitted here is the finer grade; the 40 um element is the standard choice where general protection is enough. Gauges are embedded square as standard with MPa, psi or bar scales, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. Brackets are optional, and none is included on this unit.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet flow curves against your requirement 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 curves, not as a single rated figure, so we do not state a flow number here. Contact us with your application details and we will confirm the datasheet flow curves for this size-600, PT1 unit against your requirement before you order.
The GFR family offers two filter grades: 40 um as standard and 5 um with the W code. This unit carries the 5 um element for finer protection of downstream equipment. Its drain is the automatic type (code A), which discharges collected condensate without manual intervention - a good choice where the unit sits in a position that is not checked daily. The default is a differential-pressure drain, and a manual drain is also available.
