FALCO 300 Flowrate and Pressure Drop Calculator (SVE) for older models

    This calculator applies to FALCO 300's manufactured before 3/1/2011.        
    For newer FALCO 300's click here        

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.
