1. GENERAL DESCRIPTION
EVAPORATIVE HUMIDIFIER OPERATING PRINCIPLES
FISAIR evaporative humidifiers are units designed to increase the water vapour content of the treated air, by
making use of the natural evaporation of water from its liquid phase. The air supply being treated is passed
through a cellular panel dampened using an irrigation system. This panel is composed of undulating sheets
of inorganic paper with stiffening and water absorbent additives.
The layout, as channels criss-crossing the panel provides a huge surface for water-air contact, which
maximises water evaporation, and reduces to a minimum resistance to the movement of the air (pressure
drop).
FISAIR evaporative humidifiers work in a similar way to natural processes in rivers, lakes and seas. The
vapour added to the air is exclusively pure water vapour.
PROVISIONAL STORAGE
During storage, units must be kept dry and protected from the elements.
Warning: Avoid direct sunlight and sites in which temperatures can exceed 50ºC.
Remark: Thermo-hygrometric conditions during storage:
Temperature: [-
10… 50ºC]
Relative Humidity:
[5…95%HR]
without condensation
