Blast dampers

Overview

Medray procures blast dampers for maintenance, replacement and project requirements. Provide the model or reference, quantity and operating conditions so the required configuration can be matched and sourced across available suppliers. Blast suppression dampers use reinforced blades, frames and linkages to restrict the passage of a blast-pressure event through an air opening. Some configurations latch closed after activation and require manual reset. Selection must distinguish incident from reflected pressure and account for orientation, normal airflow or static pressure, opening size and construction. Project ratings, spring settings, blade locks and materials are engineered choices, not universal attributes of every damper listed. Technical details to confirm: Blast pressure basis and duration; Mounting orientation; Normal airflow/static pressure; Opening size and flange; Blade lock/reset and construction.
