Explosion-proof Ventilator Fans
By: oleg tchechel
Consider the potential consequence if an industrial tool is dropped and strikes the blade or propeller of an exhaust / ventilation fan in use. With in a non-hazardous atmosphere, the risk for an explosion is minimal. However, if the same tool strikes the exposed, steel surfaces of a fan operating in a hazardous location containing gasoline fumes, the results could be drastically different. The blow produced by the tool could create a random spark. In the case of gasoline fumes, the addition of a proper air and gasoline fume mixture could result in an explosion. Minimizing this potential for a spark ignition is also an important reason to use spark proof tools and related equipment in hazardous locations. By incorporating basic spark proof blade / motor construction, the potential for a spark-ignited explosion caused by a direct blow is greatly minimized. The use of an explosion proof motor alone, or an aluminum blade / propeller, does not qualify the fan as "explosive proof". IMPORTANT! No air exhaust / ventilation fan is totally explosion proof. Only a product utilizing proper design and certification standards can minimize the risk of an explosion in an applicable hazardous atmosphere.(read

High Pressure Blowers
By: oleg tchechel
Side Channel blowers are oilless and have no complicated intake/exhaust valving. Most can be mounted in any plane and, with dynamically balanced impellers, generate little vibration. Because they are nonpositive displacement compressor/vacuum pumps, they discharge air that is clean and pulsation free, which are important considerations for today's plant instruments and controls.(read

Centrifugal Ventilators In Series
By: oleg tchechel
The advantage of blowers in series is that of the availbale space. If system must be expanded and increaases the CFM requirements, the allotted space for the original blower may not be large enough for a single large blower, but might be large enough to istall two smaller blowers in series to obtain the necessary pressure.(read

Duct Fan For Industrial Ventilation
By: oleg tchechel
Fan efficiency is defined as the ratio of air power (output) to shaft power requirement (input). An optimally designed fan impeller with improved aerodynamics requires less shaft input power for desired delivery of air volume with total pressure rise as per the system requirement. With reduced shaft power requirement, there is a commensurate reduction in energy consumption.(read
