The AirTAC GFR60020AF2G AirTAC Filter Regulator G3/4, Auto Drain 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 AirTAC GFR60020AF2G is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 port, an automatic drain that expels collected condensate without manual attention, standard 40 um filtration, and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Because this is the 600 size, the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), a 5 um filter element option, gauge scales in MPa, psi or bar, and G or NPT thread options alongside the PT standard. Flow figures are 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.

Installed at the G3/4 drop feeding a CNC machining cell, it strips water and chips-laden particulate from the shop air main and holds a steady regulated supply to clamps, tool changers and air blow-off circuits. The automatic drain keeps condensate moving out of the aluminium bowl on a line nobody inspects daily.
Mounted ahead of the valve manifold bank on a cartoning or case-packing conveyor line, it delivers clean, regulated air to cylinders and grippers running shift after shift. The psi square gauge lets technicians set and verify setpoint pressure at the line, and the included bracket simplifies panel-side mounting.
Used on the compressed-air feed to a lab test bench or pilot rig, it filters incoming shop air to 40 um and provides an adjustable, repeatable regulated pressure for instruments and pneumatic fixtures. The G3/4 port suits the bench's main supply, and the automatic drain protects the aluminium bowl in unattended overnight runs.
Start with the port and size: this unit is the 600 frame with a G3/4 connection, the largest step in the range, so size up to it when your line's flow demand exceeds what smaller GFR frames serve - and ask us to confirm sizing against the published flow curves before ordering. Choose the drain to match attendance: automatic (this unit) drains itself, manual suits supervised points, and differential-pressure is the default. Filtration is 40 um standard; specify the W code if you need 5 um. The square gauge here reads psi; MPa and bar scales are available. Thread is G (BSPP) on this code, with PT as the standard and NPT as an order option. A mounting bracket is included.
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 rather than a single rated figure, so we do not quote one number. Tell us your line pressure and flow demand and we will confirm the datasheet curve figures for this exact G3/4 unit on request before you order.
The A in the code means the bowl drains itself: collected condensate is expelled automatically, so the unit suits drops and installations that are not checked daily. Manual-drain versions suit supervised points, and differential-pressure drain is the default. Note that with an automatic drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), with maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C, non-freezing.
