Abstract: An inflator includes a housing, an impeller, and an airflow guide. The housing includes a intake port and a outlet port. A volute is defined between the first and outlet ports. The impeller is coupled to the housing and is in airflow communication with the volute. The impeller generates an airflow through the volute. The airflow guide is disposed in the housing and includes an air intake portion. A cutwater is monolithically formed with the air intake portion. The air intake portion is disposed flush with a portion of the volute and defines the first and port and a passageway extending from the intake port along an airflow axis. The cutwater extends from the air intake portion and is disposed between the passageway and the outlet port adjacent a circumferential edge of the impeller.

Abstract: A tool to generate airflow including a housing that has an intake port and an outlet port, and an impeller coupled to the housing. The housing at least partially defines a volute between the intake port and the outlet port, and the impeller is in airflow communication with the volute to generate an airflow between the intake port and the outlet port through the volute. The tool includes an airflow guide that is disposed in the housing and that has an air intake portion with a volute wall partially defining the volute and disposed in close proximity to the impeller. The air intake portion defines the intake port and a passageway extends from the intake port toward the impeller along an airflow axis.
