Dust Collector Fan Ventilator   By: Oleg Tchetchel
Vacuum systems are used to move and transport waste material. Sawdust, metal shavings, and other waste is easily transported away from work areas to a specified collection point for simplified clean up and removal. Vacuum systems are also used to provide suction for the manipulation of components, various materials and forming processes. These systems usually consist of long runs of relatively small diameter pipe or ducting. This results in the need for high pressure low flow fans.(read entire article)

Dust Collector Ventilator   By: Oleg Tchetchel
Fume scrubbers and wet air scrubbers protect workers from inhaling toxic elements emitted by industrial operations. Harmful fumes generated in plant environments must be contained to avoid health risks. Weld smoke collectors clean the air and protect workers from inhaling toxic elements emitted by manufacturing operations.(read entire article)

Energy Recovery Fan Ventilators   By: Oleg Tchetchel
HVAC system designers have realized the benefits of using Energy Recovery Ventilators (ERVs) in commercial and institutional buildings. However, as with many newly adopted technologies, questions of how best to apply this product are being raised. One application issue in particular is whether to apply an ERV as a stand alone unit on its own curb, or as a bolt-on accessory to a rooftop air conditioning unit.(read entire article)

Explosion Proof And Spark Resistant Fan   By: Oleg Tchetchel
Fans are often used to handle a variety of gases, dusts and materials other than clean air. Some of these gases and solid particles are combustible. When mixed at certain concentrations, ignition can result in an explosion. Even systems which are normally “safe” can become explosive under abnormal conditions. System designers must consider the safety hazard that each component of the system carries. This discussion presents some considerations that must be given to the fan.(read entire article)

Explosion Proof Spark Resistant Fan   By: Oleg Tchetchel
Industry areas such as chemical, pharmaceutical, and various industrial processes have explosive environments that require the equipment to be specially constructed to minimize the risk of gas or dust ignition. Fans are one of the items of industrial equipment that have potential to ignite either gas or dust from either sparks caused by contact of the fan wheel and housing, or because of fan motors with high temperatures, inadequate gas / dust ingress protection, or inadequate construction for prevent spark or flame propagation in to the surrounding atmosphere.(read entire article)

Fans And Blowers Noise Level   By: Oleg Tchetchel
Fan blade pass frequency is a pure tone produced when the blades of the fan wheel (impeller) rotate past the housing cut-off sheet in centrifugal fans, or the turning vanes, in axial fans. The blade pass frequency is calculated by multiplying the number of blades times the rotating speed in revolutions per minute. If this frequency matches the natural frequency of the ductwork, it can excite the ductwork, which can cause it to resonate, thereby increasing the noise level. Because of this possible increase in sound, and because certain pure tones are irritating to people, the sound output of the blade pass frequency should be investigated when sound reduction is desired. The next factor to consider is the fan design. Generally a fan operating at peak mechanical efficiency will produce less noise, because high efficiencies result from minimal air turbulence within the fan.(read entire article)

Fans And Blowers Per Atex   By: Oleg Tchetchel
The ATEX Directive applies to all countries in the EU and the European Economic Area (EEA). ATEX (ATmosphères EXplosibles) is a conglomeration of European Union (EU) directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods. Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the EU's ATEX Manufacturer's Directive (94/9/EC).(read entire article)
