Surface Mounted Blast Attenuators

The blast attenuators SMBA are stationary louvered type attenuators to be installed for the protection of HVAC air intake and outlet openings of the specified buildings subjected to a blast design overpressure lower than 0.07 barg (7 kPag), where the blast protection valves would not however close due to insufficient overpressure.

The blast attenuators are designed to provide a tortuous flow path, in order to create a significant resistance to the incoming blast wave, so to reduce the downstream
overpressure. The attenuators are suitable for both vertical and horizontal installation .
