The AirTAC GFR600C20ANTK AirTAC Filter Regulator NPT3/4 Auto Drain 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 GFR600C20ANTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 configuration carries a 3/4 in NPT port, a metal bowl (aluminium alloy at the 600 size) with an automatic drain, a 40 um standard filter element, and a fitted reverse/check valve. No gauge is fitted in this configuration. 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 port sizes from 1/8 to 1 inch, and options include manual or automatic or differential-pressure drains, a 5 um element (code W), gauge and scale choices, G or NPT threads, and bracket variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Installed at a 3/4 in branch take-off from a plant air main, it cleans water and scale out of the supply and holds a set pressure for the machines on that branch, with the automatic drain and check valve handling condensate and back-flow without daily attention.
Feeding tool-clamp cylinders, chip-sweep jets and air-actuated enclosures on a machining centre, it gives the machine a filtered, regulated air supply sized on a 3/4 in line, protecting downstream valves and cylinders from water and debris.
Mounted ahead of the valve manifold that runs conveyor diverters, reject pushers and bag-blow nozzles on a packaging line, it keeps the operating pressure steady across the shift while the automatic drain clears condensate from the metal bowl.
Size 600 is the largest step in the GFR range and carries a 3/4 in port, so match it against the pipe size and air demand of the circuit you are feeding. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. This unit has an automatic drain, which suits unattended installations where regular manual draining is impractical; manual-drain and differential-pressure-drain variants are available if you prefer a different regime. The 40 um element is the standard grade; a 5 um element (code W) is offered where finer filtration is needed. No gauge is fitted here - gauge and scale options exist on the family if you want local pressure indication. The thread on this unit is NPT; G (BSPP) and PT are the other catalogue options. A mounting bracket is included, and the fitted check valve holds downstream pressure if the upstream supply is lost.
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 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 demand and we will confirm the flow from the datasheet for this exact configuration before you order.
No gauge is fitted on the -N configuration, but the GFR family offers gauge options with square or round dials and MPa, psi or bar scales if you want local indication. The trailing K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply drops.
