The AirTAC GFR600C25ALC2K AirTAC Filter Regulator 1 in. PT 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 GFR600C25ALC2K is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 configuration is fitted with a PT1 (1 in) PT-thread port, an automatic drain that ejects collected condensate from the bowl without manual attention, a 40 um standard filter element, and a low-pressure regulator type. It carries a round pressure gauge reading in psi, a reverse/check valve, and a mounting bracket. The size 600 bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi); operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 5 um (code W) filter element, embedded square or external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and flow 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.

Installed at the drop from a plant air header, it strips water and scale from the supply and holds a steady low-pressure setting for the downstream distribution loop, with the automatic drain clearing condensate through the shift.
Feeding cylinder and valve manifolds on a packaging conveyor, the unit conditions the air and keeps the low operating pressure the actuators were set up for, while the psi gauge gives operators a visible line check.
Built into an OEM machine's air preparation section, the filter-regulator protects downstream directional valves and air cylinders from water and particulate, and the check valve holds the circuit's setting if the supply dips.
Start with size and port: this unit is size 600 with a PT1 (1 in) PT-thread port, the largest step in the GFR range - step down to 200/300/400 if your line's flow demand is smaller. Drain choice matters: this unit has an automatic drain (code A), which suits unattended duty; manual and differential-pressure drains are available on other codes. The filter grade here is the 40 um standard element; specify code W for 5 um where finer particulate removal is needed. The gauge on this code is a round, psi-scale type; embedded square gauges and MPa or bar scales are the other options. Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket is included. Because flow is published as curves rather than a single rating, 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 GFR600 series as curves, not as a single rated figure, so we do not quote one number. Send us your line pressure, set pressure and air demand and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code means the bowl has an automatic drain, so collected condensate is ejected without manual draining. The L means it is the low-pressure regulator type, intended for lower set-pressure duty; the exact regulation range for this variant is not published in our sheet, so we confirm it on request. The unit also carries a round psi gauge, a reverse/check valve, a 40 um element and a PT1 (1 in) PT-thread port.
