Abstract
Abstract A housing for an air filter having a detachable cover and base plate on opposite ends. The cover and base plate are secured to the housing by means of a clamping ring which is provided with a sealing gasket and/or O-ring for perfecting a seal therebetween. The cover includes a receptacle for receiving an inlet duct which is secured to the cover by a clamping ring. The housing includes a receptacle for an outlet duct which is secured to the housing by a clamping ring. An air filter is disposed within the housing to form an inlet plenum and an outlet plenum which facilitate airflow through the filter element. The cover includes a collar for securely locating the air filter element within the housing.
