The AirTAC GFR60020LC2W AirTAC Filter Regulator PT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60020LC2W is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point in a single body. This size 600 unit has a PT3/4 port, the 5 um filter element (the W grade, finer than the standard 40 um), a differential-pressure drain that discharges condensate on the pressure drop created by flow, and the low-pressure regulator type (code L). The bowl on this 600 size is aluminium alloy, a mounting bracket is included, and the gauge fitted is the external round type with a psi scale.
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 include manual or automatic drains, 40 um or 5 um elements, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and bracket choices. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow 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.

Feeds clamping cylinders on an automotive weld fixture that hold at a low regulated set point, with the 5 um element keeping directional valves and cylinders free of water and fine particulate.
Supplies filtered, regulated air to spray-nozzle atomizing headers on a coating line, where the low-pressure regulator type matches the modest set point and the round psi gauge suits US operators.
Placed ahead of the cylinder bank on a carton-packaging conveyor so actuators run on water-stripped air at a stable low pressure, with the differential-pressure drain handling condensate across shifts.
Choose the size and port against the air demand of the circuit: this unit is size 600 with a 3/4 inch PT thread, the largest step in the range. The 5 um element (code W) suits circuits with finer components downstream; the standard grade is 40 um. The drain here is the differential-pressure type, which bleeds condensate automatically as air flows; automatic (A) and manual (M) drains are the alternatives in the family. The gauge fitted is the external round type reading in psi; embedded square gauges with MPa, psi or bar scales are the catalogue alternative. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included. The L in the code marks the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so ask us to confirm it against your set point. Flow is published as curves, not a single rating, so send us your air demand and we will 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 GFR600 as curves rather than a single rated figure, so no rated flow number is quoted here. Send us your air demand and operating pressure and we will confirm the datasheet curve and sizing before you order.
L marks the low-pressure regulator type, intended for lower set points than the standard version; the catalogue does not publish its exact adjustment range, so we confirm it on request. The C2 code fits the external round gauge with a psi scale; the embedded square gauge with MPa, psi or bar scales is the catalogue alternative.
