The AirTAC GFR600C20LF3WT AirTAC Filter Regulator NPT3/4 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 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 GFR600C20LF3WT is an AirTAC GFR filter regulator: water and particulate filtration plus pressure regulation combined in one body for compressed air. This size 600 unit is configured with a 3/4 in NPT port, the low-pressure regulator type, a 5 um filter element (code W), a differential-pressure drain, and an embedded square gauge with a bar scale. The metal bowl on size 600 units 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 ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um optional filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

At a bottle-rinse blow-off station, the 5 um element keeps water carryover and scale out of the air knives while the low-pressure regulator holds a gentle, steady blanket pressure across the nozzle row.
Hold-down and clamp cylinders on a carton-packing conveyor receive filtered, regulated air at a low set pressure, so cartons are gripped firmly without being crushed.
A 3/4 in pilot-air takeoff feeding positioners and solenoid valves on a water-treatment skid: the 5 um grade protects small pilot orifices and the low-pressure regulator holds the reduced pilot pressure.
Size and port: 600 is the largest GFR size, with a 3/4 in port on this unit; step between 200/300/400/600 (1/8 in to 1 in) to match the air demand of your line. Drain: this unit uses the differential-pressure drain (the default); automatic (A) and manual (M) versions are available. Filtration: the 5 um element here (code W) is the finer option against the 40 um standard - choose it where downstream valves and cylinders need cleaner air. Gauge: embedded square gauge with a bar scale (code F3); psi or MPa scales and an external round gauge are options. Thread: NPT here; PT is the standard thread and G (BSPP) is also available to order. A bracket is included. Flow is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing from the datasheet 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.
Flow for the GFR series is published as curves, not as a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing for the GFR600C20LF3WT directly from the AirTAC datasheet.
The L in the code marks the low-pressure regulator variant, intended for circuits that run below standard mains pressure. The exact adjustment range for this variant is not published on the sheet we work from, so we confirm it on request. The rest of the code decodes as: NPT3/4 port, 5 um element (W), square gauge with bar scale (F3), differential-pressure drain, and bracket included.
