The AirTAC GFR600C25ALJC2K AirTAC Filter Regulator PT1 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 GFR600C25ALJC2K is a size 600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 inch PT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a low-pressure regulator type for applications that operate below standard pressure ranges. It is fitted with an external round gauge scaled in psi and a reverse/check valve, and it is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge style and scale, and a reverse/check valve option. Flow is published as curves rather than a single rating, so 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.

Feeds a workshop press circuit that runs at reduced regulated pressure: the 40 um element stops scale and pipe rust reaching the valve stack, the automatic drain keeps condensate out of the cylinder, and the psi gauge gives the operator a direct setting reference.
Sits at the drop of a packaging conveyor's air ring, filtering water and particles from the main supply and holding a steady low regulated pressure to the diverters and clamp cylinders so actuation stays repeatable through the shift.
Prepares control air for loom and spinnerjet manifolds: the low-pressure regulator type suits circuits specified below standard pressure, the check valve holds the setting against supply dips, and the automatic drain protects the fine jets from moisture carryover.
Start with the port step: this unit is size 600 with a 1 inch PT port, the largest step in the range, so match it to the pipe size and the air demand of the line. Choose the drain to suit access: automatic (this unit) drains itself, manual suits attended stations, and differential-pressure is the default where a pressure drop can trigger the purge. Filter grade is 40 um standard; select the W code for 5 um where finer protection is needed. Gauge style is embedded square as standard with an external round gauge optional, scaled in MPa, psi or bar (this unit: round, psi). Thread is PT as standard with G (BSPP) and NPT as order options, and the J code omits the bracket.
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 l/min, m3/h or SCFM number. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code specifies an automatic drain, so collected condensate is expelled without manual attention - useful where the unit is mounted in an inaccessible spot. The C2 specifies the optional external round gauge scaled in psi; the embedded square gauge scaled in MPa, psi or bar is also available as a code option.
