Air blower and filter assemblies

摘要

Compact blower and filter assemblies for providing clean air to work place and other enclosed environments wherein the blower cooperates with an intermediate baffle to direct incoming air radially outwardly toward opposite endwalls of the assembly housing after which the air flows downwardly across and through a filter element which closes the discharge end of the housing. The intermediate baffle is generally rectangular in configuration having four corners adjacent which are disposed angled deflectors which direct air inwardly with respect to the corners of the housing as the air passes toward the filter and which incorporates a plate which reflects blower noise.
