Why Choose the Quest 876 Exhaust Duct Kit?
Large-scale indoor cultivation facilities require effective humidity management and carefully planned air circulation.
The Quest 876 Exhaust Duct Kit allows growers and facility operators to direct the dehumidifier's discharge air through a dedicated duct system.
This provides greater flexibility when positioning equipment outside the growing area or distributing conditioned air to another location within the facility.
When combined with a compatible Quest intake duct kit, it can support a ducted dehumidification arrangement that keeps equipment accessible while maintaining air circulation between the dehumidifier and the conditioned space.
Flexible Exhaust Air Connections
The kit is designed to attach securely to the discharge side of compatible Quest dehumidifiers.
It supports two common ventilation configurations:
Quest recommends dedicated ductwork for each dehumidifier, with a maximum recommended duct run of 25 ft (7.6 m).
For Quest 876 installations, ductwork must be designed to maintain static pressure below 0.25 in. w.g. (approximately 62 Pa).
