The AirTAC GFR600C25ALJF1TK 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 GFR600C25ALJF1TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 configuration is built with a 1 in NPT port, an automatic drain that ejects collected condensate from the aluminium alloy bowl without manual attention, and the standard 40 um filter element. The regulator is the low-pressure type for circuits that call for reduced regulating ranges; the exact range for this type is not published in the catalogue and is confirmed on request. A square pressure gauge on the MPa scale is fitted, a reverse/check valve is included, and no mounting bracket is supplied.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in up to 1 in, and options including manual or differential-pressure drains, a 5 um element (code W), external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and mounting brackets. Flow for GFR units is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure for your application before ordering.

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.

Filter the shop air and hold a reduced regulated setting for spray-booth atomizing circuits, with the automatic drain keeping condensate out of the finish air.
Condition a 1 in main line feeding big pneumatic process valves and cylinder actuators, filtering the air and regulating pressure to the actuator control circuit.
Treat the main air feeding pneumatic conveyor and gating drives on a bottling line, with the fitted check valve holding the downstream circuit if the supply dips.
Step size by port and flow: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, while sizes 200/300/400 step down through 1/8 in to 3/4 in. Drain choices are automatic (fitted here), manual, or the differential-pressure default. The 40 um element is standard; specify code W for 5 um filtration. Gauges are embedded square as standard, with optional external round gauges in MPa, psi or bar scales. The thread here is NPT; PT is the standard thread and G (BSPP) is an order option. Brackets are optional and this configuration is supplied without one. 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 GFR units as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and required flow and we will confirm sizing from the datasheet on request.
The L code marks the low-pressure regulator type, intended for low-pressure circuits; the exact regulating range for this type is not published in the catalogue, so we confirm it on request. The A code is the automatic drain, which ejects collected condensate from the aluminium alloy bowl without manual intervention.
