The AirTAC GFR600C25ALF2T AirTAC Filter Regulator NPT 1 in 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 GFR600C25ALF2T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries 1 in NPT ports, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, a low-pressure regulator type, and an embedded square gauge scaled in psi. The metal bowl on this size is aluminium alloy, and a mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature range of -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 options include a 5 um element (code W), manual or differential-pressure drains, alternative gauge scales, G (BSPP) or NPT threads in place of the PT standard, and low-pressure regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds filtered, regulated air to impact wrenches and pneumatic clamps at high-volume assembly stations, with the automatic drain keeping condensate off the tools between shifts.
Supplies cleaned air to conveyor diverters and bag-forming cylinders on a packaging line, where the low-pressure regulator holds a gentle setting for delicate product handling.
Prepares air for quarter-turn pneumatic valve actuators on a plant skid, combining water and particulate removal with stable regulated supply to the positioner and solenoid valves.
Start with size and port: the 600 frame with 1 in NPT ports is the largest step in the GFR range, so match it against the pipe diameter and air demand of the circuit it feeds. Choose the drain to suit access: this unit's automatic drain suits installations that are not checked daily, while manual and differential-pressure drains are available elsewhere in the family. The 40 um element is the standard grade; specify the 5 um W option if finer filtration is needed. The fitted square gauge reads in psi; MPa and bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as orderable options, and a bracket is included for mounting. Because flow is published as curves rather than a single rating, 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 GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your line pressure and air demand and we will confirm the flow curve and sizing from the datasheet on request.
The A in the code means an automatic drain: collected condensate is expelled from the aluminium bowl without operator attention. Across the GFR family you can also order manual (M) or differential-pressure (blank) drains, and a 5 um element (W) instead of the standard 40 um, if your application calls for it.
