The AirTAC GFR600C20LF3WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20LF3WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 600 unit has a 3/4 in NPT port, a 5 um filter element (code W), a differential-pressure drain and an aluminium alloy bowl. It is the low-pressure regulator type, and the fitted square gauge reads in bar. A reverse/check valve is built in and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options that include manual or automatic drains, the 40 um standard element, alternative gauge scales and G or NPT threads in place of the PT standard. Maximum 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.

Feeding an air-over-oil press or clamping circuit that runs below standard line pressure, where the low-pressure regulator holds a steady setting and the 5 um element protects the control valves.
Point-of-use conditioning on a packaging machine's 3/4 in main, filtering water and fine dirt out of plant air before it reaches the machine's directional valves and cylinders.
Supplying stop-and-sort gates and pusher cylinders along a bottling or carton conveyor, with the reverse/check valve helping hold the setting if upstream supply dips.
Match the size and port to the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the range, so step down to 200, 300 or 400 if your line draws less air. Drain choice matters: differential-pressure drain is fitted here, while automatic and manual drains are order options. The standard element is 40 um; this unit carries the finer 5 um W element for added protection of downstream components. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are decodable choices, and the bracket can be specified with or without. Flow is published as curves, not a single rating, so 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.
AirTAC publishes flow for the GFR series as curves rather than 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 GFR600C20LF3WTK from the datasheet on request.
The W selects the 5 um filter element instead of the 40 um standard, for finer protection of downstream valves and cylinders. The L selects the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so we confirm it on request. The drain fitted here is differential-pressure, and automatic or manual drains are order options.
