Abstract
An air powered flush machine capable of circulating a highly volatile flushing solvent through an air conditioning system or system components and then also capable of circulating a high volume of air through the system or components, to blow the solvent out of the components and thoroughly dry the system or components, without emitting an objectionable level of odour or hazardous level of fumes through the machines air exhaust outlet. The machine utilizes a receiving tank design which separates liquid solvent from the air flow before exhausting the air through its exhaust filter.
