Thermo VentilatorsUse of Housing

Mechanically Automatic Thermo Ventilator by detecting temperatures.

The revised construition regulations which require the frequency of ventilation into the room and device of some ventilators conforming to these requirements has become compulsory for buildings. As this thermo ventilator, thermoelement built-in as activator, does not use electricity, it is a sort of ecological products that leads to saving resources. It opens fully to get the maximum frequency of ventilation when an open air temperature is high, while when it is getting cold, adjusts the opening space to the minimum to prevent the inflow of open air. It keeps the room temperature warm and improves the warming efficiency.
The mechanism of this ventilator into operation is that the thermoelement mounted on the upper of duct senses open air temperatures and opens and closes the butterfly valve mounted in the inside of duct. Or it is possible to switch the air flow direction by manual operation of the front cover flap.
