The AirTAC GFR60020LF2T AirTAC Filter Regulator NPT3/4, 3/4 in 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 GFR60020LF2T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain on the bowl, and the low-pressure regulator type with an embedded square gauge scaled in psi. A 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 of -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 to 1 inch, and options include automatic or manual drains, a 5 um element (code W), alternative gauge scales, and G (BSPP) or NPT threads in place of the PT standard. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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. 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 a workshop pneumatic press from a 3/4 in main: the GFR60020LF2T strips water and swarf from the plant air and holds a low, steady working pressure at the press, with the psi gauge giving the operator a direct setting reference.
On a bottling or cartoning line, the unit conditions and regulates the air driving conveyor stopper and pusher cylinders, protecting the actuators from condensate and keeping their stroke speed consistent at a low set pressure.
At a lab bench air drop, the filter regulator cleans the house supply and lets the user dial in a gentle, low working pressure for air-driven bench apparatus, with the differential-pressure drain clearing collected water from the aluminium bowl.
Choose the size and port step against the air demand of the circuit: the 600 size with its 3/4 in port is the largest step in the GFR range, so confirm the flow curve against your consumption before ordering. Drain type is a real choice here: this unit uses the differential-pressure drain (the default), while automatic (code A) and manual (code M) versions can be ordered. The 40 um element is standard; specify the W code if the application needs 5 um filtration. The embedded square gauge is fitted in psi on this model, and MPa or bar scales are available instead; an external round gauge is optional. Thread is NPT on this unit, with PT as the catalogue standard and G (BSPP) as an order option. A mounting bracket is included. Because flow is published as curves, not a single rating, ask us to confirm sizing against the 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 rather than a single rated figure, so we do not quote a rated flow number. Send us your air demand and line conditions and we will confirm the sizing from the datasheet curves on request before you order.
This model uses the differential-pressure drain, the GFR default, which discharges collected condensate from the bowl when the pressure differential across the element rises. If you prefer, automatic (code A) or manual (code M) drain versions of the same size can be ordered instead.
