Our Air & Dirt Separator - Magnetic Filter MF-D DRYL is engineered to enhance central heating systems by continuously removing large magnetic and non-magnetic particles. Acting as both a magnetic filter and air vent, it improves system efficiency, protects against rust and corrosion, and extends boiler lifespan. By capturing tiny magnetic shards and black ferrous oxide sludge, it prevents blockages and maintains optimal heat transfer, ensuring reliable performance and energy savings throughout your heating system. Ideal for maintaining cleaner, more efficient central heating operations.
