The Watts MKLR Microvent is a high-performance, compact automatic air vent designed to continuously extract trapped air and micro-bubbles from sealed central heating and cooling systems. Air pocket accumulation is a primary cause of system inefficiencies, localised cold spots on radiators, pump cavitation damage, and acoustic pipe noise. The Microvent features a precision side-venting design, allowing it to be installed easily in tight enclosures, manifolds, or complex boiler casing layouts where vertical clearance is limited.
