In a refrigeration system in which coils are mounted in a coil passage, a fan system is provided by which air is caused to pass over the coils. The fan system includes a housing communicating with a coil passage. The housing has an intake and an outlet each with a mouth, the mouths of the intake and outlet being oriented substantially 180.degree. from on another. A centrifugal scroll caged blower is mounted in the housing and an electric motor is connected to rotate the blower. Baffles are provided within the housing for directing air in separate paths through the housing intake to an inlet of the blower and from the blower through the housing outlet, the flow of the air through the housing mouths lying in substantially parallel planes.

Refrigeration centrifugal blower system

The present invention provides a centrifugal blower wherein the noise at the cutoff has been substantially reduced by providing a vortex in the air flow near the cutoff to redirect the air flow. A fin projects downwardly into the space created by the exhaust outlet to redirect the air flow away from the cutoff and create a vortex to quiet the air flow.
