Ruskin model CBS8BL Blast Suppression Damper is designed to provide protection against instantaneous pressure changes resulting from blast-related events such as dust/vapor cloud explosions. Installed as air intake or exhaust devices in structures such as chemical storage areas, refineries, military bases, and mechanical rooms, the Ruskin model CBS8BL will suppress blast waves which would otherwise advance into adjoining areas, protecting equipment and building systems. With performance data validated by independent testing, the Ruskin model CBS8BL offers low pressure drop characteristics while providing protection against reflected blast pressures up to 44 psi, according to the company.
