Fan operation

Elevator in motion, doors are close
The sterilization and purification fan delivers the air from the hoistway into the car. This air is sterilized by the UV light in the air inlet and then travels through the negative ion generator to provide secondary negative ion sterilization. This settles dust in the car and ensures a safe environment.
Elevator landed, doors are open
In the case of the continuous use of the fan, the air blows into the car and creates positive pressure. When the car door is open, the air flows out. Throughout the car, the purification fan works and keeps the air sterilized and purified. 

Installation and maintenance

It is not recommended to install the cab sterilization fan together with any other existed fans. Consider to install the cab sterilization fan in place of existing exhaust fan.
The unit permanently mounts on top of the elevator. The unit is not waterproof and designed for indoor installation only. Do not clean or wipe unit while in use to prevent personal injury accidents. The installation height of the wind blade is higher than 7.5 feet. The ultraviolet germicidal lamp should be replaced every 5000 hours.
