TYPES OF DISCHARGE DOORS:

There are three types of discharge outlets:

Accordion Type Damper Discharge:

The accordion discharge is recommended for use on trash chutes. The discharge is a UL labeled fire damper, held open by a 165°F fusible link and equipped with tension coils on either side of the damper to permit closing if the link

breaks. Monthly inspections of the discharge should be made to ensure that the links are intact and that no waste

has collected in the horizontal tracks, which might interfere with its closing path.
 

 

Rolling Incline Type Discharge:
The discharge door of UL construction, is held open by a 165°F fusible link. The door will roll shut if the link is melted. Monthly inspections of the discharge should be made to ensure that the link is intact and that no waste has collected in the horizontal tracks of the discharge, which might interfere with its closing path.
 

 

Hopper Type Discharge:
The hopper type discharge is UL labeled and typically used on linen chutes. The discharge is top hinged and held open by chains with a 165°F fusible link. The hopper type discharge can also extend into the discharge room from the ceiling and is supported on a pedestal(s). The hopper discharge should be kept clean and free of damage.
