The AirTAC GFR600-20T 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 AirTAC GFR600-20T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is supplied with a 3/4 in NPT port, a 40 um filter element, an automatic drain, and an embedded square gauge scaled in bar. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The aluminium alloy bowl suits this larger 600 size.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include a 5 um element (code W), manual or differential-pressure drain, alternative gauge scales in MPa or psi, G or NPT threads, and a no-bracket variant. Flow is published as curves rather than a single rating, so we confirm datasheet and flow 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.

Positioned at the air inlet to a CNC machining cell, this filter regulator strips water and swarf-carrying particulate from the shop air line and holds a steady regulated pressure to the machine's pneumatic valves and clamps.
Mounted on the air drop feeding a packaging line, the unit cleans condensed, particle-laden plant air and regulates the pressure supplied to the pick-and-place and case-sealing cylinders, with the automatic drain clearing condensate continuously.
Installed at a point-of-use air drop on the factory floor, this 600-size filter regulator conditions the main header supply and sets a stable downstream pressure for the tools and actuators served by that drop.
Size and port step up from 200 through 600 as flow demand grows; this 600-size unit carries a 3/4 in NPT port (PT is the standard thread, with G and NPT available as order options). Drain choice is automatic here, with manual and differential-pressure variants offered in the series; the filter grade is the 40 um standard, with a finer 5 um element (W) optional. The embedded square gauge is scaled in bar, and MPa or psi scales are alternatives. A mounting 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 this unit is published as curves in the AirTAC datasheet, not as a single rated figure, so we do not quote one number. Tell us your application and required conditions and we will confirm the flow and datasheet figures on request before you order.
The automatic drain on this GFR600-20T ejects collected condensate from the bowl without manual intervention, which suits unattended duty. Manual and differential-pressure drain variants are also available in the GFR series if you prefer a different service approach.
