Summary

The extreme ambient conditions in the Middle East present unique challenges to ventilation engineers. The majority of industrial-
type buildings, including factories and warehouses, are typically naturally ventilated for practical more than economic reasons. This is because electrically driven fans have a very short life expectancy, and the maintenance cost to replace them is many times more expensive than the fans themselves. Hence the rotary wind ventilator has proven immensely popular and has, up until now been the only cost-effective option for maintaining reasonable internal conditions for process and personnel alike. Unfortunately, these rotating devices are not immune to the harsh environment, and the bearings often seize due to loss of lubrication and dust ingress. Hence. ideally a roof ventilator that does not rotate, yet still uses the wind-induction effect to extract air is a desirable alternative. Such a device has been invented and performance tested using a wind tunnel, to satisfy this market.
