The AirTAC GFR600-20T AirTAC Filter Regulator 3/4 in NPT 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 PT3/4" ports, a automatic 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 GFR600-20T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit is fitted with a 3/4 in NPT port, an automatic drain that purges collected condensate without manual attention, a 40 um standard filter element, and an aluminium alloy bowl. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi), and an external round gauge scaled in bar is fitted. A mounting bracket is included; no reverse/check valve is fitted. Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which 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, a 40 um standard or 5 um (code W) fine element, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Cleaning and regulating the shop-air feed that powers tool-change cylinders, clamps and pneumatic actuators on a machining centre, with the automatic drain handling condensate on a continuously running line.
Conditioning the air feeding stopper gates, pusher cylinders and diverters along a bottling conveyor, where one unit filters water and debris out of the supply and holds a steady regulated pressure to the actuators.
Serving as the main air-prep point at a 3/4 in drop feeding an assembly cell, filtering the compressed air and setting the working pressure for the cell's air tools and fixtures, with the round bar gauge giving operators a local pressure readout.
Start with the port and size step: the GFR600 with its 3/4 in NPT port suits larger supply lines, while GFR200/300/400 cover smaller ports - match the step to the flow your line needs. Choose the drain to suit access: automatic (this unit) for unattended duty, manual where you want controlled purging, or the differential-pressure default. Pick the element grade: 40 um standard for general air prep, 5 um (code W) where finer filtration is wanted. Gauge style and scale (square embedded, or external round in MPa, psi or bar) and thread family (PT standard; G and NPT as order options) are also decodable choices, as is the bracket.
Because flow for the G-series is published as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm the datasheet and correct sizing before you order.
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 G-series flow as curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your line size and air demand and we will confirm the datasheet curves and check the sizing against your application on request.
The A in the code GFR60020AC3T specifies an automatic drain, which purges collected condensate from the bowl without anyone opening it - useful on unattended or continuously running lines. The alternatives in the series are manual drain (code M) and the differential-pressure drain (blank), which vents when the pressure differential rises. All three share the same 0.15-0.9 MPa (20-130 psi) regulation range on this configuration.
