The AirTAC GFR600C25AJC1T AirTAC Filter Regulator 1 in NPT 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 GFR600C25AJC1T is a GFR-series filter regulator: water-and-particulate filtration and pressure regulation combined in one body, size 600 with a 1 in NPT port. This configuration carries an automatic drain, the standard 40 um filter element, an external round pressure gauge reading in MPa, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The 600-size bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus a choice of manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and optional brackets. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Filtering and regulating the supply at a 1 in compressor-room drop before it feeds the factory ring main, protecting every downstream branch from water and particulate carryover.
Supplying filtered, regulated air to large quarter-turn pneumatic actuators on isolation and control valves in a water-treatment or process plant, holding a steady setpoint to the actuator.
Conditioning the air feed to cylinder-driven gates, diverters and stoppers on a heavy packaging or bottling conveyor line, where a stable regulated supply keeps indexing consistent.
Choose the size by port and required flow: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range. Drain choice matters in service: the automatic drain fitted here ejects condensate without attention, while manual and differential-pressure drains are the alternatives. Filtration is the standard 40 um element; specify the W option for 5 um where downstream equipment needs finer protection. The round gauge on this code reads in MPa; embedded square gauges and psi or bar scales are also available. The thread is NPT on this code; PT is the standard and G is available to order. Flow is published as curves, not a single rating, so 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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet on request.
This code carries an automatic drain, which ejects collected condensate without manual attention. The GFR series is also available with a manual drain and with the standard differential-pressure drain. Note the regulation range differs by drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains, and 0.05-0.9 MPa (7-130 psi) with a manual drain.
