The EBM Papst RadiPac EC centrifugal fans are designed for air handling units. RadiPac centrifugal fans are medium pressure devices. The "Pac" in RadiPac means "packaged", because all required functions: motor, control are packed into one fan and are on-board.

All RadiPac fans adhere to tougher new minimum efficiency requirements of the ErP Directive for fans, effective as of 2015. The motor efficieicy of the GreenTech EC (electronically commutated) motors exceeds the requirements specified in efficiency class IE4, and is achieved without the use of rare earth magnets.

The impellers are welded aluminium, the lightness of which minimises bearing loads on the motors, maximising durability while delivering high circumferential velocity.
