How does it work?
This humidifier is a by-pass type designed for warm
air plenum mounting, and is precision engineered to meet
local building codes and heating system requirements nationwide.
This state-of-the-art whole house furnace humidifier is
backed by a one year warranty and include the patented "Media
Cone". This device permits maximum air flow through and
around an evaporative media containing a humidifier pad, which
is treated with Sylgard™ (a special formulation of Dow
Corning that combats bacteria and fungus growth and helps
keep the air cleaner).
The Autoflo Whole House Furnace Humidifer Models
400BP (out of production, parts available) and 800BP plenum models are by-pass humidifiers which
use a motorized rotating evaporative pad for increased efficiency.
By-passed air is passed through the evaporative pad where
it is moisturized and then returned to the furnace blower
for circulation throughout the house. For maximum efficiency,
the humidifier must be mounted on the warm air side |
