Verantis® helps you control your environment with High Efficiency Aerosol Filtration (HEAF) Systems that are ideal for filtering and removing sticky, oily, or liquid aerosol particulate matter from VOC-laden exhaust gas streams.

HEAF systems use fiberglass or polyester filter media and the principles of impaction, interception, and Brownian motion to achieve removal efficiencies of 99.99% or higher.

HEAF systems provide an effective alternative to various applications, including applications where baghouses plug up due to the sticky, liquid nature of the particulate. HEAF systems are also useful for collecting particulate matter that is small, that cannot be easily removed from the collection plates in an electrostatic precipitator, or that has an improper resistivity to carry an electrostatic charge. HEAF systems are also a cost-effective alternative to fume or vent gas incinerators.

HEAF Filtration Devices

  • Manually-operated, affordable Mini-HEAF for gas flows between 0 and 5,000 ACFM
  • Fully automatic Flat-Bed HEAF for gas flows from 500 to 15,000 ACFM
  • Fully automatic Rotary Drum (DF) HEAF for gas flows from 9,000 to 100,000 ACFM

Markets and Applications

Typical markets and applications that benefit from HEAF systems include:

  • Plasticizer
  • Asphalt saturator
  • Food processing
