The AirTAC GFR600C20LF2WK AirTAC Filter Regulator PT3/4 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 GFR600C20LF2WK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit is fitted with a PT3/4 (3/4 inch) PT-threaded port, a 5 um filter element (code W, versus the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. The regulator is the low-pressure type, and the embedded square gauge on this code reads in psi; an external round gauge is available as an option. The aluminium alloy bowl and mounting bracket are included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 inch to 1 inch, drain, filter-grade, gauge, thread (PT, G/BSPP, NPT) and bracket options to match. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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 machining-cell fixture line running at reduced supply pressure, the GFR600C20LF2WK filters the shop air to 5 um and holds the clamping circuit at a stable low setting, with the check valve retaining clamp pressure if the main supply drops.
Upstream of the valve manifolds and air cylinders on a bottling or filling line, this 3/4-inch filter regulator conditions the plant air - removing water and fine particulate - and sets the pressure the actuator bank was designed around.
For paint-spray or coating equipment that operates below standard line pressure, the low-pressure regulator type with a 5 um element keeps oil-free, dry, finely filtered air at the gun or applicator, with the psi gauge giving a direct local reading.
Step up through the size range (200 / 300 / 400 / 600) and its matching port (here 3/4 inch PT) as your required flow grows; the datasheet publishes flow as curves, so have us check the curve against your consumption before ordering. This code carries the 5 um element (W) rather than the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need finer filtration. The differential-pressure drain is the default and suits most fixed-duty installations; automatic and manual drains are alternatives in the family. The embedded square gauge here reads psi (MPa and bar scales are the other options), the reverse/check valve (K) is fitted for pressure retention, and the bracket is included. PT is the standard thread; G (BSPP) and NPT are order options. If you need a defined regulation window, note this is the low-pressure type and we will confirm the exact range on request.
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 series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air consumption and we will confirm the flow and sizing from the datasheet on request.
W is the 5 um filter element (the family standard is 40 um), and K means a reverse/check valve is fitted so downstream pressure is held if the upstream supply is lost. This unit uses the differential-pressure drain as standard: condensate collected in the aluminium bowl is discharged automatically when the pressure drop across the element reaches the drain's threshold, with no manual draining needed during normal operation.
