The AirTAC GFR600C25ALF2K 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 AirTAC GFR600C25ALF2K is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit carries a 1 in PT port, an automatic drain, the standard 40 um filter element and a low-pressure regulator type. An embedded square gauge with a psi scale is fitted, a reverse/check valve is included, and the aluminium alloy bowl comes mounted on a bracket.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 in up to 1 in, and each unit can be ordered with a different drain type, filter grade, gauge style and scale, or a G (BSPP) or NPT thread instead of PT. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures and the datasheet for this exact configuration 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 the regulator and valve stack on a pneumatically clamped press where filtered air must be held at a low setpoint; the low-pressure type and the psi-scale square gauge suit a circuit that is set and checked in psi.
Installed as the point-of-use filter regulator on a 1 in air drop serving a packaging hall, removing water and pipe scale from the main supply before it reaches the hall's directional valves and cylinders.
Conditions the supply to pneumatic conveyor drives and stopper cylinders on a bottling line, with the automatic drain dealing with condensate so the line does not depend on someone draining a bowl each shift.
Size and port set the air capacity: this is the largest GFR size, 600, with a 1 in PT port, chosen when the line demand sits at the top of the range; smaller sizes step down through 3/4 in, 1/2 in and below. The automatic drain (code A) handles condensate on its own; manual (M) and differential-pressure (blank) drains are the alternatives if you prefer scheduled or load-linked draining. The 40 um element is the standard grade; specify W for the 5 um option. The gauge on this code is the embedded square type reading in psi; an external round gauge with MPa, psi or bar scale can be ordered instead. PT thread is standard here, with G (BSPP) and NPT as order options, and the mounting bracket is included. The low-pressure regulator type has a set range that is not published as a single figure - confirm it with us against your setpoint. Because flow is published only as curves, send us your demand and we will confirm sizing from the datasheet 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line demand and working pressure and we will confirm the sizing from the datasheet on request.
This code carries the embedded square gauge with a psi scale. An external round gauge is available as an option, with MPa, psi or bar scales - tell us which scale you want when ordering. The reverse/check valve (K) and the automatic drain (A) are already fitted on this configuration.
