INTRODUCTION
The Temspec unit ventilator is designed as means for providing heating, cooling and
ventilation to the classroom. Our goal is to help create an enhanced learning environment
by focusing on the following points when designing our equipment:
•COOLING, HEATING, HUMIDITY AND VENTILATION
CONTROL
•AIR DISTRIBUTION
•SOUND ATTENUATION
By installing the vertical unit ventilator into the classroom, superior control can be obtained
for each room. Because the unit can be ducted, an even distribution of air can be achieved
throughout the room. The unit ventilator is constructed with heavy gauge metal and sound
absorbing insulation for optimal sound attenuation.
By applying sound engineering principles and thorough testing, we ensure the highest
quality of performance in our unit ventilators.
