The AirTAC GFR600C25ALJC2W AirTAC Filter Regulator PT1 Low-Pressure 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.
This GFR600 filter regulator combines water and particulate filtration with pressure regulation in a single body. This configuration is built around a 1 in PT threaded port, a 5 um filter element (the finer of the two published grades), an automatic drain that clears collected condensate without manual attention, and the low-pressure regulator type. It is fitted with an external round gauge reading in psi, and the 600-size bowl is aluminium alloy. The unit is supplied without a mounting bracket.
This is a genuine AirTAC part in the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing 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.

Point-of-use filtration and pressure setting on a brewery bottling hall's low-pressure air header, keeping condensate and pipe scale out of downstream valves and actuated rinse nozzles, with the automatic drain handling the water collected at the drop leg.
Filtered, regulated air for the pneumatic clutch-brake and divertor cylinders along a corrugator conveyor line, where the 1 in port serves a high-consumption main and the 5 um element protects the control valves fed from it.
A retrofit filter-regulator for the air circuit of a workshop pneumatic press, where the low-pressure regulator type and a round psi-scale gauge let the operator set and read the working pressure directly on the press frame.
Size and port step up together across the GFR range - 200, 300, 400 and 600 - and this unit sits at the top of the range on a 1 in PT port, so choose it when your demand sits high on the flow curve. Drain choice is a real decision: differential-pressure (the default), automatic (this unit) or manual. Filter grade is 40 um standard or 5 um with the W code (this unit). Gauges come as an embedded square gauge or an external round gauge, in MPa, psi or bar scales - here a round psi gauge is fitted. Thread is PT as standard, with G (BSPP) and NPT as order options, and this unit carries no bracket. Note that this is the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so we confirm it on request. Because flow is published only as curves, not a single rated figure, send us your air demand and we will confirm the right size from the datasheet 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 rather than a single rated figure, so there is no one number we can honestly quote. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The A in the code selects the automatic drain, which ejects collected condensate without anyone opening the bowl - useful on lines that run unattended. The W code selects the 5 um element instead of the 40 um standard, for finer particulate removal ahead of sensitive valves and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing.
