Exterior Fan Silencer
Exterior ventilation fans have a 38dB noise rating. This slight noise can be eliminated by positioning each fan into an Exterior Fan Silencer (EFS). The number of EFS units needed depends on the size of the WhisperRoom™ and the number of ventilation systems required. This option may be required when a more controlled sound environment is needed in the host room. NOTE: May be ordered and installed at any time.

As requirements change, some clients may find that they need a larger isolation enclosure than their original needs dictated. To accommodate this occurrence, expansion packages are available for most SE 2000 Series WhisperRooms. Units with model numbers beginning with 60, 72, 84 or 102 consist of two or more piece ceilings/floors and can be expanded in one direction. Units with model numbers beginning with 42 or 48 have single piece ceilings/floors and cannot be expanded. Units with model numbers beginning with 60, 84 and 102 can be expanded in 18 inch (1.5′) and 42 inch (3.5′) increments. Units with model numbers beginning with 72 can be expanded in 24 inch (2′) and 48 inch (4′) increments. Expansion packages consist of two additional walls, 1 ceiling, 1 floor and seam seals. These components, in addition to all components from the original, smaller, WhisperRoom unit, are used to construct the larger unit. No components purchased as part of the original unit are left unused. All 42 and 48 inch expansion packages include one ventilation set. Contact a Product Representative for pricing.
