Description
The Caleffi 551066A 1″ Press Discal Air Separator is a hydronic system built to remove entrained air and microbubbles from circulating water to maintain proper system balance and operation. It favors use cases such as heating and cooling loops where trapped air can affect flow, cause noise, or reduce heat transfer efficiency. It operates through an internal chamber that slows fluid movement, allowing microbubbles to collect, combine, and rise for automatic discharge. Positioned within HVAC systems, it integrates with piping circuits to maintain clean fluid circulation and reduce corrosion risk.
