The AirTAC GFR600C25LJF2GK AirTAC Filter Regulator G1 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.
The GFR600C25LJF2GK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds a reduced, adjustable downstream pressure. This configuration is built around a G1 (1 in) port with G (BSPP) thread, the low-pressure (L) regulator variant, 40 um standard filtration, and a differential-pressure drain that bleeds accumulated condensate away as air flows through. The 600 size carries an aluminium alloy bowl, and this unit includes an embedded square gauge scaled in psi plus a fitted reverse/check valve (K); no mounting bracket is included (J), though a bracket is available as an option. Working temperature is -5 to 70 C (non-freezing) with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and options including 5 um (W) filtration, automatic or manual drains, gauge scales in MPa, psi or bar, an external round gauge, and PT or NPT threads in place of G. Because AirTAC publishes flow only as curves rather than a single rating, we confirm flow and full 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.

Spray booths and coating heads need air that is dry, clean and held at a gentle, steady pressure so atomisation stays even. This unit filters water and particulate before the guns and regulates the supply down to the low setting the finish demands, with the psi gauge giving the operator a direct read at the point of use.
Air knives and blow-off nozzles that dry or dust containers before filling or labelling run best on filtered air at a mild, stable setting. The G1 port feeds the manifold, the 40 um element protects the nozzles from scale and condensate, and the check valve keeps the circuit from back-feeding if the supply drops.
Laboratory and process sparging - aerating a tank, agitating a bath or purging a vessel - calls for clean air delivered at a low, repeatable pressure. This filter regulator conditions the supply ahead of the sparge ring, and the low-pressure variant is intended for exactly this kind of gentle-duty regulation.
The meaningful choices in this code are the 600 size with its G1 (1 in) port - the port step generally tracks the air demand of the line, so move up a size when demand is high; the low-pressure (L) regulator variant, selected when the downstream process runs at gentle pressures rather than near full line pressure; the 40 um standard element versus the 5 um (W) option where finer protection matters; and the differential-pressure drain, which suits steady-flow installations, while automatic or manual drains better match intermittent duty. The fitted K reverse/check valve helps hold downstream pressure if the supply drops, and the F2 code selects the embedded square gauge scaled in psi (MPa or bar scales and an external round gauge are alternatives). Thread here is G (BSPP), with PT (the family standard) and NPT available to order, and J means no mounting bracket. 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 on the page. Send us your line pressure, the downstream pressure you need and your expected air demand, and we will confirm the flow and full datasheet figures for this exact model on request before you order.
The L marks the low-pressure regulator variant: the unit filters and regulates like any GFR, but its regulation is intended for processes that run well below full line pressure. The exact adjustment window for the low-pressure type is not published in the standard tables, so we confirm it on request. If your process runs at conventional pressures, the standard GFR600 in the same G1 port is the corresponding alternative.
