The AirTAC GFR600C20LJF2W AirTAC Filter Regulator PT3/4, 5 um 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 GFR600C20LJF2W is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 5 um filter element (code W), a differential-pressure drain that bleeds condensate automatically as flow passes through, a low-pressure regulator type, and an embedded square gauge reading in psi. The 3/4 inch PT port suits larger supply lines, and the size 600 bowl is aluminium alloy. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of drain types, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for 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.

Feeding clean, pressure-controlled air to gripper and clamp actuators on a robotic welding cell, where the 5 um element protects fine control valves from particulate carryover.
Filtering and regulating the air feeding sealing and flap-fold cylinders on a packaging conveyor, with the psi gauge letting line staff verify set pressure at a glance.
Conditioning the main drop feeding pneumatic presses and workholding fixtures in a machine shop, where the 3/4 inch port matches the header line and the low-pressure type suits reduced set pressures.
Start with the port step: this unit is size 600 with a 3/4 inch PT port, the largest in the GFR range, so step down to size 400 or below if your line is 1/2 inch or smaller and your air demand is modest. Choose the drain to match access: differential-pressure (this unit) drains as air flows, automatic drains on a timer-free cycle, and manual needs someone to open the bowl. Pick 40 um for general line protection or 5 um (this unit, code W) where finer particulate control matters. Gauge scale is selectable (MPa, psi or bar) and the thread can be ordered as PT, G (BSPP) or NPT; a bracket is optional.
Because flow is published as curves rather than a single rating, send us your application details and we will confirm the correct size against 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 figure, so we do not quote a number here. Tell us your application and operating pressure and we will confirm the flow from the datasheet on request before you order.
The W in the code GFR600C20LJF2W selects the 5 um filter grade; the blank default is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer particulate control. If you only need general water and dirt removal ahead of shop-floor tooling, the 40 um version is the usual pick.
