The AirTAC GFR600C20LF2WTK 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 GFR600C20LF2WTK is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body, removing water and particulate from compressed air and holding a set downstream pressure. This size 600 unit carries a 3/4 in NPT port, the 5 um filter element (code W), a differential-pressure drain, and the low-pressure regulator type (code L) for circuits whose setpoints sit below the standard band. The embedded square gauge is fitted with a psi scale, a reverse/check valve is fitted (code K), and the mounting bracket is included. The metal bowl - aluminium alloy at size 600 - collects condensate, which the differential-pressure drain expels as the pressure drop across the element rises.
This is a genuine AirTAC part. The GFR family is made in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, with manual, automatic or differential-pressure drains, 40 um standard or 5 um elements, and gauge and scale choices. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Filtered air at a low regulated setpoint feeding clamp cylinders on a CNC fixture line, with the fitted check valve guarding the downstream circuit against reverse flow and the psi gauge giving a local setpoint readout.
Clean, 5 um-filtered air at a low regulated pressure for valve actuators along a rinse-and-fill line, with condensate collected in the aluminium bowl and expelled by the differential-pressure drain.
Low-pressure regulated air for diverting gates and stop cylinders on a sorting conveyor, where the 3/4 in port serves the larger line and the square psi gauge lets operators verify the setting at the machine.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the family. The 5 um element (W) suits circuits that are sensitive to finer contamination; the 40 um standard element remains available if coarser filtration is acceptable. The drain here is differential-pressure, which discharges condensate when the pressure drop across the element rises; automatic (A) and manual (M) drains can be ordered instead. The square gauge is fitted with a psi scale, and MPa or bar scales plus an external round gauge are options. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. The reverse/check valve (K) is fitted and the bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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.
Flow for the GFR600 is published as curves rather than a single rated figure, so we do not quote a number on the page. Send us your line pressure, downstream air demand and acceptable pressure drop, and we will confirm the datasheet figures for this exact model on request before you order.
The L marks the low-pressure regulator type, intended for circuits whose setpoints sit below the standard band. Its exact adjustment range is not published in the catalogue, so confirm the setpoint you need with us before ordering; the standard type is available if your operating range is conventional.
