The CALEFFI 551806 Air Separator is a highly efficient solution designed to automatically remove air in all forms, including microbubbles, ensuring optimal performance of the systems it is installed in. This product belongs to the DISCALSLIM series, which is specifically engineered for installations equipped with wall-mounted boilers, making it an ideal choice for under-device mounting. With a maximum operating pressure of 3 bar and a working temperature range of 0 to 110 °C, this air separator is versatile and reliable for various applications involving water and glycol solutions.

One of the standout features of the DISCALSLIM is its unique internal structure that minimizes pressure loss, allowing for seamless operation. The specially designed channels direct a portion of the water flow into the air collection chamber, where the flow slows down and creates turbulence, effectively separating microbubbles from the medium. As these bubbles accumulate, they trigger a float mechanism that opens the discharge line, ensuring continuous air removal and preventing issues such as noise, oxygen corrosion, and localized overheating.

Constructed from high-quality materials, including a PPAG40 body and stainless steel components, the CALEFFI 551806 ensures durability and long-lasting performance. The use of EPDM seals further enhances its reliability, making it a superior choice for maintaining the efficiency and safety of your heating systems.
