The AirTAC GFR600C25ALJF2K AirTAC Filter Regulator PT1 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 GFR600C25ALJF2K is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body, with no lubricator. This size 600 unit carries a PT1 (1 in) PT-threaded port, the largest standard port step in the G-series, so it suits a main air line rather than a drop to a single machine. The 40 um element removes water and particulate to the standard grade, the automatic drain expels collected condensate from the bowl without anyone opening it, and the low-pressure regulator type is intended for circuits set well below the standard range. The embedded square gauge is fitted and reads in psi, and a reverse/check valve is fitted so downstream pressure is held if the upstream supply drops.
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, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (W) fine element, square or optional external round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads as order options. Rated flow for this family is published as curves rather than a single figure, so ask us and we will 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.

Drops off a 1 in compressor ring main feeding a whole work cell. The filter regulator cleans the header air and sets a stable low working pressure for everything downstream, with the automatic drain handling condensate on a line that runs shifts without attention.
Supplies a bank of air clamps and swing cylinders on a CNC fixture table. The low-pressure regulator holds the clamping pressure the fixture designer specified, the 40 um element keeps debris out of the valve stack, and the check valve holds clamp pressure if the plant supply dips.
Feeds blow-off nozzles that dry or clear product on a conveyor line. The 1 in port delivers the volume a bank of nozzles needs, the regulator sets the gentle low pressure the product tolerates, and the automatic drain keeps free water out of the blow-off air.
Size and port are the first decision: step up through 200, 300, 400 and 600 as your required air delivery grows, and this unit sits at the top with a PT1 (1 in) port. Next, drain type: automatic drain (this unit) suits lines that run unattended or where nobody will reliably bleed the bowl; manual drain is the lowest-cost choice where an operator passes daily; the differential-pressure default drains on a pressure drop. Element grade is 40 um standard on this unit; choose the W code for 5 um when downstream equipment needs finer filtration. The square gauge is fitted here reading psi; MPa or bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and this J-coded unit ships without a mounting bracket, so plan your panel or frame fixing accordingly. Because rated flow is published only as curves, not a single number, send us your flow and pressure requirements and we will confirm sizing against 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 family as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number on this page. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow curve and datasheet figures for this exact unit on request before you order.
The L code means this unit carries the low-pressure regulator type, intended for circuits set well below the standard adjustment range; the exact range for the low-pressure type is not published, so ask us to confirm it against the datasheet. The A code in the model means the bowl drains itself automatically, so collected condensate is expelled without manual bleeding - a good fit for unattended lines. If you would rather control drainage manually, the M-coded variant of the same size is available to order.
