The AirTAC GFR600C20LF2T AirTAC Filter Regulator 3/4 in NPT 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 See datasheet 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 GFR600C20LF2T is a size-600 GFR filter regulator: it removes water and particulate from compressed air through a 40 um element and holds downstream pressure at a set point, in one body. This configuration is threaded 3/4 in NPT, uses the differential-pressure drain, carries the low-pressure regulator type, and includes an embedded square gauge scaled in psi. The bowl is aluminium alloy, as fitted on the larger 600 size, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options that include drain type, 5 um filtration (code W), gauge scale in MPa, psi or bar, G or NPT thread, and a reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so we confirm datasheet and sizing figures 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.

On a paint-shop air drop, this unit strips water and swarf from the supply line and holds a steady low set point to spray-equipment air circuits, with the psi-scaled square gauge letting operators check the setting at a glance.
On a bottling line, the 3/4 in NPT connection feeds a conveyor and gate-actuator manifold, the 40 um element keeps debris out of directional valves, and the regulator holds the low pressure those actuators are set up for.
In a machine control cabinet fed from a plant air main, this filter regulator conditions the air before it reaches pilot valves and I/P components, with the included bracket securing the size-600 body to the cabinet frame.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the series, so it suits lines where a smaller port would restrict supply. The low-pressure regulator type (code L) is intended for circuits whose set point sits in the lower part of the control range; its exact adjustment range is not published, so ask us to confirm it against your set point before ordering. Drain choice matters: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) versions are available. Filtration is the standard 40 um element; specify code W if the application needs 5 um. The square gauge here is scaled in psi; MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this code, with G (BSPP) and PT available as catalogue options, and a mounting bracket is included.
Because flow is published as curves rather than a single rating, ask us to confirm sizing from the datasheet against your application before ordering.
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 here. Tell us your line pressure, set point and air demand, and we will confirm the flow and sizing from the datasheet on request before you order.
L marks the low-pressure regulator type, intended for circuits whose set point sits in the lower part of the control range. The exact adjustment range for this type is not published in the material we hold, so ask us to confirm it against your set point. This unit also carries the differential-pressure drain, the standard 40 um element, and a square gauge scaled in psi.
