The AirTAC GFR60020C1WTK AirTAC Filter Regulator NPT3/4 5 um 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 GFR60020C1WTK is a size 600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is threaded NPT3/4 (3/4 in), carries the fine 5 um filter element (the standard element is 40 um; W selects 5 um), and uses the differential-pressure drain, which bleeds collected condensate automatically whenever the pressure differential across the element is high enough - no manual draining routine. At size 600 the bowl is aluminium alloy, and the fitted K option adds a reverse (check) valve so downstream pressure is held if the upstream supply drops. The C1 code specifies the external round pressure gauge with an MPa scale; the embedded square gauge is the standard fitting and psi or bar scales are orderable alternatives. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports 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, gauge scale options, G (BSPP) or NPT thread alternatives to the PT standard, and bracket or no-bracket mounting. Flow for this series is published as curves rather than a single rated figure, so ask us and we will 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.

Point-of-use air preparation for a CNC machining cell: the 5 um element and regulation in one body condition the supply feeding tool-change cylinders, clamps and air blast, with the check valve holding the regulated circuit if the shop supply dips.
A filter-regulator mounted at the drop feeding pneumatic cylinders and diverters on a packaging conveyor, keeping water and fine dirt out of the valves while holding a set working pressure for consistent case handling.
Conditioning the air line to a spray booth or finishing gun setup: the 5 um grade and regulated outlet give the gun a steady, drier supply, and the aluminium 600-size bowl suits the higher flow a 3/4 in booth drop carries.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up to it when the line's required flow points to a larger port - and confirm that flow with us first, because the catalogue publishes flow as curves, not a single rating. Choose the drain to match maintenance reality: differential-pressure (this unit) drains itself on pressure differential, automatic (A) drains continuously, and manual (M) needs someone to open the bowl. Pick 5 um (W, as here) when downstream equipment wants finer air than the 40 um standard element delivers. The round gauge on this unit reads in MPa; psi or bar scales are available, and the embedded square gauge is the standard alternative. Thread is NPT here; PT is the standard and G (BSPP) is the other orderable option. A mounting bracket is included, and the K option's check valve is worth specifying wherever a dropped supply must not dump the regulated downstream pressure.
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 number, so we do not quote a figure that could mislead your sizing. Tell us your application and we will confirm the datasheet flow curves and check the sizing against your required flow on request before you order.
The W in the code selects the 5 um element in place of the 40 um standard, for finer particulate and water removal ahead of sensitive equipment. The blank drain position is the differential-pressure type, which ejects collected condensate automatically when the pressure differential across the element rises - no manual drain routine. If you prefer continuous draining or a manual bowl, the A and M variants of the same size are available.
