The AirTAC GFR60020LF1T AirTAC Filter Regulator NPT 3/4 in 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 GFR60020LF1T 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 that bleeds accumulated condensate automatically as flow passes through, a low-pressure regulator type, and an embedded square gauge scaled in MPa. At size 600 the drain bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi). Operating temperature is -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, optional 5 um filtration (code W), automatic or manual drain alternatives, psi or bar gauge scales, an optional external round gauge, a reverse/check valve option, and G (BSPP) or NPT thread variants. Flow for this series is published as curves rather than a single rated figure, 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. 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.

Dropping a regulated, dried branch off a 3/4 in factory air main to feed a production cell: the GFR60020LF1T filters water and scale from the header air and holds a steady low-pressure supply to the cell.
Feeding air cylinders on a press or clamping fixture where the actuator circuit is specified below main-line pressure: one body strips condensate and particulate and sets the working pressure, with the MPa gauge giving the setter a direct readout.
Supplying wash-down-prone packaging lines and conveyor actuation at a controlled pressure: the differential-pressure drain keeps condensate moving out of the aluminium bowl during production runs without an operator bleeding it by hand.
Choose the GFR600 size when your line runs at 3/4 in porting and you want filtration and regulation combined in one body instead of two separate components. This unit uses the standard 40 um element, which suits general plant air; if the downstream equipment needs finer protection, the 5 um W-grade element is the option to specify. The differential-pressure drain is the default and needs no operator attention; an automatic drain (code A) or a manual drain (code M) can be ordered instead. The fitted square gauge reads in MPa, with psi (scale 2) or bar (scale 3) available, and an external round gauge is optional. Thread here is NPT; PT is the standard and G (BSPP) is also an order option. A mounting bracket is included with this configuration.
Because AirTAC publishes flow for this series only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm the sizing and datasheet figures against the curve 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 only as performance curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number here. Tell us your application and we will confirm the flow and datasheet figures against the curve for this 3/4 in unit on request.
The blank drain position in the code is the differential-pressure type, which uses the airflow itself to carry collected condensate out of the bowl. If you prefer an automatic drain (code A) or a manual drain (code M), those are catalogue options on the GFR600 series and can be ordered instead.
