We are a supplier of Bag Filter - Dust Collectors. These are widely used as a pollution control equipment, where woven dust filter media helps in air filtration process. Applications:  •   For collecting dust from process equipment like oven dryers, curing ovens, spray / paint boots  •   Used in the dust extraction ventilation systems  •   Pneumatic conveying vacuum air systems.
NIS-CO FANS AND BLOWERS


                                                   As an illustrative example, consider the potential consequence if a 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.
