The AirTAC GFR600C25ALC2G 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 AirTAC GFR600C25ALC2G is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit carries a G1 (1 in) G-thread port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a fitted round pressure gauge reading in psi. It is the low-pressure type, intended for circuits that run below standard regulator settings, and includes a mounting bracket.
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, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and scale options, and G or NPT thread variants to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, pressure-regulated air supplied to low-pressure coating circuits at a paint line, with automatic drain keeping condensate out of the finish without daily bowl bleeding.
Conditioning and regulating the 1 in supply feeding a bank of air-operated valves on a process skid, with the psi gauge giving operators a local setpoint reading.
Water and particle removal plus regulated pressure for the actuator and blow-off circuits on a bottling hall conveyor, where the automatic drain handles condensate load during continuous shifts.
Size 600 with a G1 (1 in) port is the largest step in the GFR range; step down to 200/300/400 if your flow demand is smaller, since port and body size scale together. The automatic drain suits unattended installations - choose manual drain only where an operator can bleed the bowl routinely, or differential-pressure drain where you want draining tied to flow conditions. The 40 um element is the standard grade; specify code W for 5 um where finer particulate removal matters. This unit is the low-pressure type, so confirm its regulation span against your working pressure before ordering. The fitted round gauge reads psi; square embedded gauges and MPa or bar scales are alternatives. G thread is the ordered option here - PT is the catalogue standard and NPT is also available. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The A in the code sets the automatic drain, which ejects collected condensate on its own - useful where the unit is not checked daily. The L sets the low-pressure regulator type, intended for circuits running below standard regulator settings; its exact regulation range is not published, so confirm it with us against your working pressure.
