The Purpose of Good Ventilation

A Mechanical Ventilation Fan drives outside air into a building in order to improve the indoor air quality.
The primary goal of introducing fresh air into a space is to remove dangerous indoor air pollutants.

An Air Exchanger exchanges air between indoors and outdoors. It’s primary goal is the bring in fresh air from outside and exchange it with the stale inside air flow.

Foreign Reports show that when air conditioning or heating is used in a room, turning on the home ventilation fan can save 15%~35% than when not. This is a great choice for indoor ventilation and air exchange.

Purpose and Function of the Ventilation Fan

The ventilation fan was designed to eliminate poor indoor air and exhaust hot humid air, unhealthy particle matter and odor to the outside. The duct’s backdraft damper will effectively block waste gas in the common duct from flowing back into the room. In general, the ventilation fan can be applied widely in homes and public places.

Flammability classes are categorized as follows :

Fireproof Level Fireproof Plastic Type Content
LOW UL94-HB
The lowest flame retardant class in UL94. For samples required to be 3~13mm thick, their burning speed must be less than 40 mm/min. For samples less than 3 mm thick, their burning speed must be less than 70 mm/min; or must go out before the 100mm mark.
UL94-V2
After the sample is burn-tested for 10 seconds 2 times, the after flame and after glow go out within 60 seconds. The falling particles can ignite cotton.
UL94-V1
After the sample is burn-tested for 10 seconds 2 times, the after flame and after glow go out within 60 seconds. The falling particles cannot ignite cotton.
UL94-V0
After the sample is burn-tested for 10 seconds 2 times, the after flame and after glow go out within 30 seconds. The falling particles cannot ignite cotton.
UL94-5VB
After the sample is burn-tested for 5 seconds 5 times, the after flame and after glow go out within 60 seconds. The falling particles cannot ignite cotton. Block-shaped samples are allowed to be burned through.
HIGH UL94-5VA
After the sample is burn-tested for 5 seconds 5 times, the after flame and after glow go out within 30 seconds. The falling particles cannot ignite cotton. Block-shaped samples are not allowed to be burned through.
