The AirTAC GFR60020LF2WTK AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" 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 GFR60020LF2WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in a single body. This configuration is built for low-pressure service, filters to 5 um (the finer of the two published grades), drains condensate by differential pressure, and carries a fitted reverse/check valve so the set point is held against backflow. The embedded square gauge reads in psi, the 3/4 in NPT port suits larger supply lines, and the size-600 bowl is aluminium alloy. Mounting bracket included.
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, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rating, so ask us to confirm the 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 cleaned, pressure-controlled air to the actuator bank of a cartoning or wrapping line, where the 3/4 in port serves a main drop and the 5 um element protects downstream valves from water and fines.
Regulating supply to workholding clamps on a machining cell that runs at low pressure, with the check valve holding the set point against upstream fluctuation so the fixture does not relax mid-cycle.
Conditioning air on a plant process header - such as a coating or drying line - where the low-pressure regulator type, aluminium bowl and differential-pressure drain suit a continuously running, larger-bore supply.
Size and port set the capacity: the 600 frame with a 3/4 in NPT port is the largest published step, so match it to the air demand of the line it feeds. Choose the drain to suit attendance: differential-pressure (as fitted here) bleeds condensate as the bowl loads, automatic suits unattended installations, manual suits periodic checks. The 5 um element (code W) is the finer published grade versus the 40 um standard - pick 5 um where downstream valves and cylinders need cleaner air. The low-pressure regulator type is selected where the circuit runs below the standard range; the exact adjustment range for this variant is not published, so confirm it with us. Gauge scale here is psi; MPa and bar scales are also available. PT is the standard thread; G and NPT are order options - this unit is specified NPT. A bracket is included.
Because flow is published as curves rather than a single rated figure, 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. The reflux valve permits reverse flow 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 line demand and operating pressure and we will confirm the flow figures from the datasheet for this exact model before you order.
The L in the code marks the low-pressure regulator variant, intended for circuits that run below the standard adjustment range; the exact range for this variant is not published, so confirm it with us. The W marks the 5 um element, the finer published grade versus the 40 um standard, chosen where downstream valves and cylinders need cleaner air.
