    摘要: A rotary roof vent consisting of a base, an impeller, an axle holding/supporting a rotating rim with blades and a cover. The impeller is solid and formed as a rim with stiffeners, and the blades are located at the outside edges of the rim. A hollow sleeve is positioned at the central part for receiving an axle. The blades are formed having a convex shape. A protrusion positioned at an acute angle disposed at the end of each blade. Another protrusion is disposed at obtuse angle to the blade and is positioned closer to the center. The blades are inserted into the impeller by 20% in relation to the base diameter. The impeller stiffeners having arch shaped configuration are adapted to follow a contour of the blades.

    摘要: 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.

    摘要: A fan apparatus has a housing with an enlarged portion defining at least one air intake and an outlet portion defining an outlet port. The outlet port has a greater width and a lesser height. A blower wheel having a plurality of fan blades is supported in the enlarged portion of the housing for rotation about an axis. A driver is connected to the blower wheel to cause rotation of the blower wheel. A flow straightener assembly is located in the outlet portion of the housing. The flow straightener assembly has first and second fins spaced apart from one another and oriented substantially orthogonal to the axis of the blower wheel. Third and fourth fins are located outside of a respective one of the first and second fins, the third and fourth fins being oriented substantially parallel to the axis of the blower wheel.
