FALCO 300 Flowrate/Inlet Pressure Calculator rev. 2/9/2009    
    This calculator applies to FALCO 300's manufactured before 3/1/2011.

This calculator provides an estimate of flow through a FALCO 300 at a catalyst temperature of 330°C with the heat exchanger bypass valve closed**.

Alternatively, if the Flow rate is known, Inlet Pressure may be estimated.

 
             
             
    Known Inlet Pressure:        
    Enter Inlet Pressure (in H20)    
    Estimated Flow Rate = (SCFM)    
             
             
    Known Flow Rate:        
    Enter Flow Rate (SCFM)    
    Estimated Inlet Pressure =
(in H20)    
             
    Opening the heat exhanger bypass valve will reduce pressure drop by    
    approximately 3-6 in WC.***          
           
 

 

* Flow greater than 360 scfm is beyond the normal operating range.

 
  ** FALCO 300 is normally operated with heat exchanger bypass closed at concentrations < 800 ppmv.
  *** FALCO 300 may be operated with the heat exchanger bypass open at high concentrations.
  Inlet pressure assumes a clean flame arrestor.  
     
   
  The FALCO 300 has a high efficiency heat exchanger.  
  High efficiency is accompanied by increased pressure drop.  
  Heat recovery is adjustable with a heat exchanger bypass valve.  
  Lowering heat recovery reduces pressure drop.
