Straight configurations can be installed onto radiators or within the system, for branch or main venting functions (multiple vents may be required for this type of installation)

Durable chrome-plated finish is both decorative and functional

all configurations are plated and are more resistant to moisture staining than unplated vents

In Heating and Air Conditioning Control Systems, the Circulation of Water Containing Impurities May Result in Rapid Wear and Damage to Components Such as Pumps and Control Valves

It also Causes Blockages in Heat Exchangers, Heating Elements and Pipes, Resulting in Lower Thermal Efficiency within the System

The DIRTMAG® Magnetic Dirt Separator Removes Both Ferrous and Non-Ferrous Impurities Continuously, Featuring Powerful Removable Magnets that Remove upto 100% of the Ferrous Impurities, Including Magnetite, that can Form in a Hydronic System

The DIRTMAG® has 2-1/2 Times the Removal performance of a Standard Dirt Separator

Anti-rotation/anti-vibration pinned float: Creates space between float and air vent wall to prevent float hang-up from debris or variations in separator installation orientation

Large-diameter chamber: Slows fluid flow dramatically. Combines with concentric, sharp-edged mesh design to cause micro-bubbles to efficiently collect and coalesce. Highly effective automatic air elimination

Anti-corrosion coalescing mesh: Constructed of glass-filled nylon. More resistant to dissolved oxygen and acidic fluids than plated metals

Robust stainless steel float linkages: Reliable float alignment even during turbulent conditions such as filling from bottom

Corrosion resistant: All components highly resistant to hydronic chemical additives or unstable pH fluid
