The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 in PT, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR600-20 is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air and holds downstream pressure steady, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). This 600-size configuration carries a 3/4 in PT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that ejects collected condensate without manual attention, a round pressure gauge reading in psi, and an aluminium alloy bowl. The regulation range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family spans four sizes (200, 300, 400 and 600) with rising port sizes and flow capacity, plus options including manual or differential-pressure drains, a 40 um standard element, square embedded or external round gauges with MPa/psi/bar scales, G or NPT threads, and low-pressure regulator variants. Flow is published as curves rather than a single rating, so we confirm the datasheet 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.

Feeding filtered, regulated air to pneumatic clamps and fixtures on a stamping line, where the automatic drain keeps condensate off the tooling during multi-shift running.
Supplying steady, clean air to conveyor-mounted packaging cylinders and diverters, with the 5 um element guarding valves from particulate carryover.
Conditioning shop air ahead of a CNC cell's pneumatic tool-changer and clamping circuits, with the psi gauge giving operators a direct setpoint check at the machine.
Size up the unit by port and expected flow: the 600 size with its 3/4 in PT port is the largest GFR frame, so step down to 200/300/400 if your line runs smaller ports or lower demand. Choose the drain to match site conditions: automatic (this unit) suits unattended or hard-to-reach installations, manual suits supervised points, and differential-pressure drains only when inlet pressure is high enough to work the drain. Pick the element grade: 40 um is standard protection, 5 um (this unit) for finer downstream air. Set the gauge scale (MPa, psi or bar) and thread (PT standard; G and NPT are order options), and add a bracket if the unit needs panel support.
One honest note before ordering: AirTAC publishes flow as curves, not a single rated figure, so ask us to confirm sizing against your actual air demand before you commit to a size.
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 this series as curves rather than a single rated number, so we do not quote a figure. Tell us your application and air demand and we will confirm the flow and datasheet figures for this 3/4 in, 600-size unit on request.
The A in the code GFR60020AC2W selects the automatic drain, which ejects collected condensate on its own instead of waiting for someone to open a manual drain. The same family is also available with a manual drain or a differential-pressure drain, and with the 40 um standard element instead of this unit's 5 um grade.
