The AirTAC GFR600C20LC2WK AirTAC Filter Regulator 3/4 in PT 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 GFR600C20LC2WK is a size-600 filter regulator: water and particulate removal plus pressure regulation in a single body. This configuration is built around a 3/4 in PT port and a 5 um filter element (code W), one step finer than the 40 um standard element, for air that needs cleaner delivery downstream. It is the low-pressure type, fitted with a round external pressure gauge scaled in psi, a reverse/check valve (code K), and the differential-pressure auto drain as standard, which bleeds accumulated condensate as inlet flow drops. At size 600 the bowl is aluminium alloy rather than polycarbonate, giving a metal pressure boundary on the filter section.
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, and each size can be ordered with manual, automatic or differential-pressure draining, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, a reverse/check valve, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures against your application before ordering.

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 process plant manifold where big quarter-turn valves are driven by sizeable pneumatic actuators, this 3/4 in filter regulator cleans the supply to 5 um, holds a low regulated pressure for the actuator line, and the check valve keeps the setpoint from backing out through the supply side.
A bottling or carton packaging line with 3/4 in air drops feeding diverters, stop gates and pusher cylinders uses this unit to strip water and fine particulate before the directional valves, with the psi gauge giving operators a local setpoint readout at the drop.
In a machining cell where low-pressure pneumatic clamps and swing cylinders run off a main plant air drop, the low-pressure regulator type, 5 um filtration and automatic differential draining keep the fixture circuit clean and stable without manual drain rounds.
Start with the port step: size 600 carries a 3/4 in PT connection, the largest standard G-series port, so it belongs on supply lines feeding high-consumption actuators or manifolds; step down to 300 or 400 if your line is 3/8 in to 1/2 in. Choose the filter grade deliberately: 40 um is the standard element, while this unit's 5 um (W) element suits downstream valves and cylinders that need finer protection. Drain choice matters: differential-pressure draining (fitted here) discharges condensate automatically as flow falls, automatic (A) drains continuously, and manual (M) requires operator attention. This is the low-pressure type, so confirm the regulation range suits your setpoint before ordering - the exact low-pressure range is not published in the catalogue and we will confirm it on request. Gauge options are the embedded square gauge or an external round gauge in MPa, psi or bar scales; this unit carries the round psi gauge. Thread is PT as standard with G (BSPP) and NPT available to order, and a mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your application details 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.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so there is no one figure we can quote honestly. Send us your line pressure, setpoint and downstream consumption and we will confirm the sizing from the datasheet curves on request before you order.
The L in the code marks this as the low-pressure regulator type rather than the standard version, intended for lower setpoint applications. The catalogue does not publish an exact regulation range for the low-pressure GFR configuration, so confirm your required setpoint with us and we will verify the range from the datasheet before ordering. The maximum inlet pressure remains 1.0 MPa (145 psi).
