Filtered power ventilator

Abstract

A filtered power ventilator includes modular constructed components allowing the device to be easily assembled, disassembled, and transported. Connection of the components is achieved without the requirement of fasteners or straps. The modular construction allows the components to be assembled in different arrangements to best suit the particular use of the device. Vacuum power can be increased by serial or parallel arrangement of motor units. One or more hose sections can be used to specifically direct a flow of air from the area to be treated to a desired exhaust location. Various filter elements can be incorporated to treat the airflow generated.

 said motor unit includes at least one handle attached to said housing.    
   
   
       8 . A ventilator, as claimed in  claim 1 , wherein: 
 said pre-filter unit includes at least one handle attached to said housing.    
   
   
       9 . A ventilator, as claimed in  claim 1 , wherein: 
 said hose unit includes at least one handle attached to said housing thereof.    
   
   
       10 . A ventilator, as claimed in  claim 1 , wherein: 
 said motor unit further includes a power cord incorporated therein and extending away from said housing, and an on/off switch wired to said motor for selective operation of said motor unit.    
   
   
       11 . A ventilator, as claimed in  claim 1 , wherein: 
 said inlet and said outlet each have a safety grill mounted thereover.    
   
   
       12 . A ventilator, as claimed in  claim 1 , further including: 
 a second section of hose connected to said outlet of said motor unit.    
   
   
       13 . A filtered power ventilator comprising: 
 a first motor unit having a housing, an inlet, an outlet, a motor mounted in the housing, a blower wheel operatively connected to the motor to produce a flow of air through said first motor unit;    a second motor unit having a housing, an inlet, an outlet, a motor mounted in the housing, a blower wheel operatively connected to the motor to produce a flow of air through said second motor unit;    a first pre-filter unit having an inlet, an outlet, and a filter element mounted therein, said outlet of said pre-filter unit connected to said inlet of said first motor unit;    a second pre-filter unit having an inlet, an outlet, and a filter element mounted therein, said outlet of said second pre-filter unit connected to said inlet of said second motor unit;    a manifold having a housing, an inlet, and a pair of outlets, one of said outlets connected to said inlet of said first motor unit, and the other of said outlets connected to said inlet of said second motor unit; and    a house unit having a housing, first and second open ends, a length of flexible hose secured in said housing, said length of flexible hose having an end selectively extendable away from said hose unit housing.    
   
   
       14 . A ventilator, as claimed in  claim 1 , further including: 
 a main filter unit having a housing, an inlet, an outlet, and a main filter element mounted therein said main filter unit being mounted between said motor unit and said pre-filter unit.
