Streivor™ Air Systems BalanceAire™ variable volume, low profile, adjustable opposed blade, dampers. The balancing dampers are engineered to be installed in hoods or ducts which are in close proximity to the hood’s exhaust plenum. The locking, unlocking and/or adjustments to the opposed blades can be made by accessing the BalanceAire™ through the hood. This eliminates the need to access the outside of the damper for adjustments. Otherwise, the damper may be inaccessible due to obstructions such as ceilings, walls, fire shafts, fire wrap materials, space restrictions or enclosures. The low profile opposed blade design is the perfect solution for balancing exhaust airflows in the extremely limited space, often available above or behind commercial kitchen ventilation hoods.
The opposed blade design of the dampers allows for an infinite amount of minute adjustments ranging from 100% open to 95% closed. This patent pending design is capable of facilitating airflow balancing by creating airflow restrictions from minor to major. BalanceAire™ Dampers are UL 710 listed and are approved for installation in exhaust hoods and grease ducts for commercial cooking equipment.
