  ENGINEERING DATA  
  Table 1 relates capacity and pressure drop to standard panel filter sizes over a broad range of operational air flow velocities.  
 
  Filter banks which are required to operate at face velocities other than those shown may be determined from the Continuity Equation:  
  system capacity, cfm  
Line
  net filter area, sq. ft.  
  = net face velocity, fpm
