The AirTAC GFR60020ALC2K AirTAC Filter Regulator 3/4in PT 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 PT3/4" ports, a automatic 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 GFR60020ALC2K is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit carries a 3/4 in PT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a low-pressure regulator type. It is fitted with an external round gauge scaled in psi and a reverse (check) valve, and the mounting bracket is included. At size 600 the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -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 include manual or differential-pressure drains, a 5 um element (code W), square embedded or round external gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. We confirm flow and other datasheet figures on request, since flow is published as curves rather than a single rated number.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeding clean, regulated air to the cylinder and gripper circuits of a cartoning or case-packing line, with the automatic drain handling condensate on a line that runs unattended through shifts.
Supplying filtered, pressure-controlled air to the clamp and hold-down cylinders of a pneumatic press or fixture station, where the check valve helps hold the downstream circuit if upstream supply is interrupted.
Regulating air to the diverters, stops and pushers along a conveyor system, with the 40 um element protecting directional valves from water and particulate carried in the shop air.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in PT port, the largest step in the GFR range. The automatic drain suits unattended installations where condensate should be expelled without operator rounds; manual and differential-pressure drains are available on other codes. The 40 um element is the standard grade, with a 5 um element (code W) for finer protection. The round gauge here is scaled in psi; embedded square gauges and MPa or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as orderable options, and the bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Note this is the low-pressure regulator type; its adjustment range is not published in the material we hold, so confirm suitability for your set pressure with us.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow data from the datasheet so you can size the unit correctly before ordering.
The A in the code means the bowl drains collected condensate automatically instead of relying on manual draining or a differential-pressure mechanism. It suits installations that run unattended or are hard to reach; manual and differential-pressure drains are available on other GFR codes if you prefer those arrangements.
