The AirTAC AirTAC GFR600C20ALF2 Filter Regulator PT3/4 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 GFR600C20ALF2 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure regulator type with a 3/4 in PT port, an automatic drain that bleeds collected condensate from the aluminium alloy bowl without manual attention, a 40 um standard filter element, and a fitted square gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, thread form (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

On a stamping or assembly press, the clamp and hold-down cylinders need a steady, lower regulated pressure while the plant air header runs at full line pressure. This filter regulator conditions the branch feed and holds the clamp setting, with the automatic drain keeping condensate out of the valve stack.
Bottling and canning conveyors run air cylinders for stoppers, pushers and lane dividers all shift long. A size-600 unit with a 3/4 in port conditions the supply to a long conveyor run, the 40 um element protecting the directional valves, and the automatic drain handles moisture without an operator visiting the drain point.
Looms and textile machines that use low-pressure air jets for thread guidance need filtration plus a regulator set well below main header pressure. The low-pressure regulator type of this GFR600 fits that duty, and the psi-scaled gauge lets the setpoint be checked at the machine.
Size 600 with a 3/4 in PT port is the step to choose when the line serves larger actuators, bigger valve islands or higher air demand than a 300/400 unit can carry - match the size and port to the required flow rather than upsizing blindly. The automatic drain on this unit suits unattended or hard-to-reach installations; choose manual drain where you want positive control of blowdown, or differential-pressure drain as the catalogue default. The 40 um element is the standard grade for general plant air; specify the W code for 5 um where downstream equipment needs finer filtration. The square gauge here reads in psi; MPa and bar scales are also available, and PT is standard thread with G (BSPP) and NPT as order options. A mounting bracket is included with this unit.
Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. The low-pressure regulator type is intended for lower regulated-pressure duty; its exact adjustment range is not published in the material we hold, so we will confirm it on request.
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 that is not in our validated data. Tell us your inlet pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet curves before you order.
The A in the code GFR600C20ALF2 means the bowl drains itself automatically, which suits installations that run unattended or are awkward to reach. The GFR family is also available with manual drain (code M) or the differential-pressure drain as the default, so you can order the drain type that matches how the machine is operated.
