Variable Air Volume

  • Variable air volume fume hoods are designed to operate in a building where the HVAC system will vary the make-up and exhaust air of the room depending on fume hood usage.
  • As the fume hood sash is raised and lowered, a separate independent electronic control system will reduce or increase the exhaust volume in order to maintain the predetermined fume hood face velocity.
  • The VAV controller/alarm are supplied by the VAV controls supplier.
