The AirTAC GFR60020LF2G AirTAC Filter Regulator G3/4 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 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 GFR60020LF2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 (BSPP) port, the 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. It is the low-pressure type, fitted with an embedded square gauge scaled in psi, and includes a mounting bracket. The size-600 bowl is aluminium alloy, and 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 ports from 1/8 to 1 inch, and options including 5 um filtration (code W), automatic or manual drains, alternative gauge scales, G or NPT threads, and a reverse/check valve. Flow is published in the catalogue as curves rather than a single rated figure, so we confirm the exact flow and 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. 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.

Installed at the drop from a 3/4 inch compressed-air main to condition and hold supply pressure for a production department, with condensate managed by the differential-pressure drain.
Feeding filtered, regulated air to directional valves and cylinders on automated machinery, with the psi square gauge giving operators a local setpoint readout.
Conditioning the air supply to conveyor clamp and gate actuators on a packaging or material-handling line, where the low-pressure type suits lower working-pressure circuits.
Size 600 with a G3/4 port is the largest step in the GFR range, so start there when your line is plumbed at 3/4 inch or your flow demand sits above what smaller bodies serve; verify against the published flow curve before ordering. The differential-pressure drain on this unit suits steady-running installations that see regular pressure swings; choose automatic drain (code A) for unattended sites or manual drain (code M) where you want controlled purging. The 40 um element is the standard grade for general plant air; specify 5 um (code W) only where downstream equipment needs finer filtration. The fitted square gauge reads in psi; MPa and bar scales are available, as are G and NPT thread options in place of the standard PT, and the bracket is included on this configuration.
Because catalogue flow is given as curves rather than one rated number, ask us to confirm sizing for your application 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this exact G3/4, size-600 unit before you order.
The L in the code marks the low-pressure regulator version, intended for circuits that run below standard working pressures; the exact adjustment range for this variant is not published, so we confirm it on request. The drain is differential-pressure type: it vents collected condensate automatically when the pressure drop across the 40 um element rises, with no manual purging needed.
