• Operating at very slow switching speeds
• Operating with very low air inlet pressures
• Pumping continuously for very long periods
• Frequent start stop applications utilizing either liquid or air shut off valves
• Operating with very long discharge lines
• Filter press applications
• Where pump icing / freezing is a common ocurrence
• Where air consumption efficiency is a critical factor in pump choice
