The AirTAC GFR600C25ALF2G 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 GFR600C25ALF2G is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G1 (1 in) port with G thread, an automatic drain that handles collected condensate without manual attention, the standard 40 um filter element, and a low-pressure regulator type with an embedded square gauge reading in psi. The size 600 bowl is aluminium alloy, and a mounting bracket is included.
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, and options including manual or differential-pressure drains, a 5 um element (code W), alternative gauge scales (MPa, psi, bar) and PT or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures against 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.

Mounted at a 1 in main drop in a bottling plant, the unit strips water and particles from the compressed air and regulates a low-pressure supply feeding the hall's pneumatic valves and actuators, with the automatic drain handling condensate between shifts.
Installed ahead of a machining cell's air distribution manifold, it cleans the shop supply and holds the regulator at the set point the cell's clamps and tool-change cylinders were set up for, with the psi gauge giving operators a direct read of line pressure.
On a treatment-plant valve skid where actuated butterfly and knife-gate valves run at reduced supply pressure, the unit filters the incoming air and regulates it down within the low-pressure type's range, keeping the actuator circuit supplied from a single 1 in connection.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this unit sits at the top of the range with a 1 in G-threaded port. Choose the drain to suit access: automatic (this unit, code A) for unattended condensate removal, manual (M) where you want operator-controlled blowdown, or differential-pressure (blank) as the catalogue default. Filter grade is 40 um standard; specify W for the 5 um element where downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar; this unit reads psi) and an external round gauge is optional. Thread is PT as the catalogue standard with G and NPT as order options, and the bracket is included. Note this is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than a single rated figure, 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code GFR600C25ALF2G means the automatic drain: collected condensate is expelled without an operator having to open the drain. The catalogue also lists manual (code M) and differential-pressure (blank) drains for the GFR family, so if your installation suits a different arrangement, we can quote that variant.
