ABSTRACT:
A filter unit adapted for receiving a flow of fluid potentially carrying particulate material and for holding filters transverse to the flow is disclosed, and in one preferred application of the invention the flow is an air stream containing radioactive particles. The filter unit has a generally cubic-shaped housing having a fluid inlet opening and a fluid outlet opening in two opposite surfaces and preferably these openings are provided with flanges. The housing is also provided in its lateral surfaces with a first opening and a second opening enabling insertion and removal of filters though these openings. The openings are preferably in the same lateral surface or wall. Each opening has a door means mounted to close the opening with each door means being capable of being opened at least 90.degree. to the lateral surface of the housing on which the door means is mounted. The housing also has a clamping means near the first opening and a clamping means near the second opening for securing each door means to the housing to close the associated opening. One door means has attached on the inside surface a platform with two apertures for receiving two indexing studs upon closing and clamping the door to the housing. The other door means has the inside surface forming a filter changing catch pan for collecting and holding particulate material as well as supporting the filter during changing thereof. The housing also has two means for receiving and securely holding filters inside the housing adjacent each opening, and one of the means for receiving and securely holding a filter is a pressure frame means having two indexing studs mounted thereon for engaging respectively the two apertures for receiving the two indexing studs in the platform. Two embodiments of the pressure frame means are presented.
