High Pressure Regenerative Blower
By: oleg tchetchel
High pressure 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

Spark Resistant Ventilator Fan
By: oleg tchetchel
Spark resistant explosion proof ventilator may be required in any area where the presence of flammable gases, vapors or finely pulverized dust in the atmosphere is sufficient to create a threat of an explosion or fire. It may also be required where easily ignitable fibers or flying's are present. The following information is a representative, but is not an all-inclusive, list of the types of locations and operations that require hazardous location air exhaust / ventilation equipment in at least certain areas. Consult the current National Electric Code® for complete and current information.(read

Chemical Duty Blowers And Fans
By: oleg tchetchel
In high concentrations Hydrogen Sulfide can be lethal. It occurs in natural gas, oil, volcanic emissions, and some mineral springs. In oil refining processes its presence is undesirable, and it must be removed. The Clause process is one of the methods used to remove the hydrogene sulphide, and while doing so, recover elementar sulfur.(read

Vaneaxial Fans For Ventilation
By: oleg tchetchel
Vent ducts in contemporary large houses becomes so long and elaborated that even a high pressure furnace fan couldn't generate enough static pressure to blow through the whole length of such a duct. The existing low pressure booster duct fans, even though compact enough to be installed in-line in the house ventilation ductwork, still do not provide enough booster pressure / airflow. The usual solution to this problem was installation of two independent furnaces with different air ducts, which is rather expensive option.(read

Suggestion For Building Ventilating
By: oleg tchetchel
Normally the recommended methods of plants ventilation and cooling are exhaust fans or oower roof ventilators (PRVs). To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and/or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure.(read
