Sound attenuators reduce noise produced by fan units and other equipment within Heating, Ventilating and Air Conditioning (HVAC) systems. Mounted within the system’s ductwork, they ensure that a specific noise criteria is achieved within the internal or external areas served.

DBZ offers the design and engineering assistance to integrate our line of duct silencers, sound attenuators into a system solution. As a result you may choose from a selection of standard or custom engineered duct silencers that will satisfy the requirements of each application.

Prime candidates for noise control measures are openings into and out of noisy environments. This includes the ventilation of buildings, enclosures, and equipment rooms. Integration of noise control measures such as silencers and louvers, into the system design requires careful consideration of space constraints, fan selection and aerodynamic pressure losses. Our sound attenuators have adequate silencing capabilities, low air resistance and are as small as possible
