Our multiple fan systems deliver uniform air distribution, increasing the efficiency of downstream components like coils and filters, while reducing low-frequency noise and improving reliability with built-in redundancy.

White Paper: Technical Information on
Paralleling Fans

A Rosenberg ECFanGridTM consists of a series of EC-Fans used parallel. The resulting air flow is proportional to the number of fans used, with the pressure conditions remaining the same. Download the white paper to get complete technical detail about paralleling
