BETEC CAD. B-10 Series Acoustic louvers are used as a part of Intake / Exhaust air system 

of building equipment to reduce noise generated by the system.                                                                                                                                                                                                                           

BETEC CAD. B-20 Series Acoustic louvers provide significant broadband attenuation to low velocity 

openings while minimizing line of sight through the opening. 

BETEC CAD. B-30 Series Acoustic louvers design provides least air resistance and significant 

attenuation to the openings or enclosures with less pressure drop.
