The AirTAC GFR600C20MLNT 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 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 GFR600C20MLNT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and reduces pressure in a single unit. This 600-size configuration is built with a 3/4 in NPT port for larger air lines, a 40 um filter element, a manual drain that you open by hand during maintenance, and the low-pressure regulator type for circuits that run at reduced set pressures. The 600-size bowl is aluminium alloy, a mounting bracket is included, and no gauge is fitted on this unit.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options including automatic or differential-pressure drains, a 5 um element (code W), round or square pressure gauges, and G (BSPP) or NPT threads in place of the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

On a bottling line, the unit strips water and particulate from the plant air and holds a reduced, low-pressure supply to the filler's pneumatic cylinders and grippers, with the manual drain emptied during scheduled changeovers.
In an automotive refinish booth, the 40 um element catches water and dirt before they reach the spray gun, while the low-pressure regulator lets the painter set a gentle, repeatable atomizing pressure; the manual drain is bled off between jobs.
On a carton packaging conveyor, the unit feeds clean, regulated low-pressure air to hold-down clamps and diverters, with the 3/4 in NPT port serving the branch line that supplies several stations.
Size the unit by port and flow: the 600 size with its 3/4 in NPT port suits higher-flow branch lines, while the 200, 300 and 400 sizes cover smaller ports. Drain choice matters: this model uses a manual drain, which you open by hand during maintenance; automatic and differential-pressure drains are available on other configurations if the unit sits somewhere hard to reach. The 40 um element is the standard grade; specify code W for 5 um where finer filtration is needed. This unit is supplied without a gauge, but round or square gauges with MPa, psi or bar scales can be ordered. The thread here is NPT; PT is the AirTAC standard and G (BSPP) is also available. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet 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 flow for the GFR series as curves rather than a single rated figure, so there is no one rated-flow number we can quote. Tell us your line pressure and the flow your application needs, and we will confirm the figures from the datasheet on request before you order.
This configuration uses a manual drain: you open it by hand to release collected condensate, which suits lines that are checked regularly. If the unit is mounted somewhere hard to reach, other GFR configurations offer automatic or differential-pressure drains instead. The 40 um element is standard here; a 5 um element is available as code W.
