Air intake silencer assembly

Abstract

An air intake silencer assembly at the intake of an air handling system includes a plenum housing having an inlet end for receiving air and having an outlet port for discharging air. Two baffle panels in spaced relation in the housing define, with the housing, an inlet chamber, a central chamber, and a discharge chamber. A plurality of tubular members is supported by the baffle panels and each includes a perforated core and a sound dissipating fiber wrapping. Air flows into the inlet chamber, through the plurality of tubular members to the discharge chamber, and is discharged from the discharge chamber through the outlet port.

       2 . The air intake silencer assembly of  claim 1 , wherein the core is stainless steel.  
   
   
       3 . The air intake silencer assembly of  claim 1 , wherein the fiber wrapping is cotton.  
   
   
       4 . The air intake silencer assembly of  claim 1 , wherein the tubular member is a water filtration device.  
   
   
       5 . The air intake silencer assembly of  claim 1 , wherein the housing is generally box shaped.  
   
   
       6 . The air intake silencer assembly of  claim 1 , wherein the baffle panels are identical.  
   
   
       7 . The air intake silencer assembly of  claim 1 , wherein the baffle panels and the tubular members comprise a removable subassembly.  
   
   
       8 . The air intake silencer assembly of  claim 1 , wherein the area of the perforations on the outer surface of the core is approximately 30% of the outer surface of an identical core without perforations.  
   
   
       9 . The air intake silencer assembly of  claim 1 , further including an outwardly extending flange at the inlet end, wherein the flange is used to secure the device to an air intake filter.  
   
   
       10 . The air intake silencer assembly of  claim 9 , wherein a pipe connects the outlet port and an air handling system.  
   
   
       11 . The air intake silencer assembly of  claim 1 , wherein the tubular members are all generally parallel to each other.  
   
   
       12 . An air intake silencer assembly at the intake of an air handling system, the air intake silencer assembly comprising, 
 a plenum housing including an inlet end for receiving filtered air,    at least two baffle panels in spaced relation in the housing and with the housing defining an inlet chamber, a central chamber, and a discharge chamber, and    a plurality of tubular members substantially located within the central chamber, each tubular member including ends supported by the baffle panels and including a perforated stainless steel core and a sound dissipating fiber wrapping,    wherein the filtered air flows into the inlet chamber, undergoes reflection and pressure equalizing in the inlet chamber, flows from the inlet chamber through the plurality of tubular members to the discharge chamber, undergoes reflections and pressure equalizing in the discharge chamber, and is discharged from the discharge chamber through an outlet port of the housing.    
   
   
       13 . The air intake silencer assembly of  claim 12 , wherein the tubular member is a water filtration device.  
   
   
       14 . The air intake silencer assembly of  claim 12 , wherein the housing is generally box shaped.  
   
   
       15 . The air intake silencer assembly of  claim 12 , wherein there are two identical baffle panels.  
   
   
       16 . The air intake silencer assembly of  claim 12 , wherein the baffle panels and the tubular members comprise a removable subassembly.  
   
   
       17 . The air intake silencer assembly of  claim 12 , wherein the area of the perforations on the outer surface of the core is approximately 30% of the outer surface of an identical core without perforations.  
   
   
       18 . The air intake silencer assembly of  claim 12 , further including an outwardly extending flange at the end with the inlet port, wherein the flange is used to secure the device to an air intake filter.  
   
   
       19 . The air intake silencer assembly of  claim 18 , wherein a pipe connects the outlet port and an air compressor.  
   
   
       20 . The air intake silencer assembly of  claim 12 , wherein the tubular members are all generally parallel to each other.
