Gas blower and method utilizing recirculation openings
First Claim
1. A blower comprising a housing comprising a first wall portion, an inlet formed through the first wall portion for receiving a gas, a second wall portion, an outlet formed through the second wall portion for discharging the gas, a first series of recirculation openings formed through the second wall portion, and a second series of recirculation openings formed through the second wall portion;
- impeller means in the housing for receiving the gas from the inlet, pressurizing the gas, and passing the gas to the outlet for discharge; and
a separator extending between the first and second series of openings for respectively directing a first portion of the gas exiting from the outlet to the first series of openings for recirculation back into the housing, and a second portion of the gas exiting from the outlet to the second series of openings for recirculation back into the housing.

Abstract
A gas blower and method according to which the gas is introduced into the inlet of a housing where it is pressurized by rotating impellers. The pressurized gas is directed to a discharge plenum from which a first portion of the gas is discharged. The remaining portion of the gas is passed from the discharge plenum through a plurality of openings to a recirculating chamber for recirculating the gas back to the housing. The gas is passed from the recirculating chamber back to the housing through two radially-spaced sets of angularly-spaced openings formed in the housing.
