EPC Exhaust Fans Play A vital Role In...
Ventilation in a factory is a delicate problem. Serious air pollution from excessive heat, smoke and dust affects the general health, overall efficiency and output in a factory. EPC Exhaust Fans will solve this problem.
Many badly planned public auditoriums become hot and stuffy immediately after their doors are closed and the show begins .
Ceiling fans or air circulators cannot ease this situation except Exhaust Fans.
Most cafeterias lack proper ventilation--cooking odors
and steamy - muggy air float constantly. It is desirable that EPC Exhaust Fans should be fitted here to enable people to eat their food at ease.
Although banks in metropolitan cities are better ventilated, it's not so in towns and villages . The hectic working pattern in banks require hygienic and comfortable working condition - ensured only by Exhaust Fans.

A library room should be airy and damp - proof as possible both for the health and hygiene of library users and thousands of books stored therein. EPC Exhaust Fans protect it from moisture, pollution and contamination.
Our kitchen and toilet are often gloomy and stuffy with insufficient air inlets. They need
minimum 10 to 20 air changes per hour. EPC Mini Exhaust Fans eliminate malodor and stuffiness.
Besides general ventilation, EPC Exhaust Fans are widely used in Room Coolers - the most effective and economical device used in dry and low humid climates to keep houses and working places cool and
comfortable. The 450 mm (18") single phase 720 r.p.m. and 920 r.p.m. fans are ideal for domestic purpose and 600 mm (24") 720 r.p.m. and 920 r.p.m. for large Room Coolers in cinema halls, restaurants, etc. Simple enough, one can make such a cooling unit at home at a very low cost. |
| Air Change-The Sole Solution |
Air change is thus the most vital factor for an environment. Varying from location to location, it depends upon the surrounding, the number of people working and also the nature of work. A bank or an office requires much less air changes than a foundry or a boiler house. The table shown is a general guide. To determine the number of Exhaust Fans required, multiply the cubical content of room (length x width x height) in metre or feet by the number of air changes required and divide the result by air delivery of fan (see table).
