Commercial Ventilation Fan
By: oleg tchetchel
If an individual is to produce maximum results, he must be allowed to function in an environment as nearly ideal as can be provided. In fact, the benefits in terms of efficiency and productivity can be substantial. Failure to provide a comfortable environment can be very expensive in terms of errors, work slow-down, complaints, absenteeism, etc. If the major factor is a hot, humid atmosphere, which may include smoke, dust, fumes or other irritants, a practical and effective approach to the problem is available. To obtain a reasonable degree of personnel comfort in hot weather, there are three basic factors that should be provided for in the ventilation and cooling system of a commercial or industrial building.(read

Duct Fans - Canadian Blower
By: oleg tchetchel
Axial flow Canadian Blower ventilators have blades that force air to move along the shaft about which the blades rotate. Axial fans blow air across the axis of the fan, linearly, hence their name. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in wind tunnels.(read

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

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

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

How To Increase Blowers Performance
By: oleg tchetchel
The proper design of the ventilation system plays a large role in achieving the overall desired performance. Visual inspections often reveal some easily rectified problems that can significantly impair performance. If the system has not been properly maintained, clogged filters or obstructed coils will reduce airflow. The greater the obstruction, the greater the loss in airflow. Any leaks in the ductwork will contribute to reduced performance, especially leaks around plenum bulkheads that can lead to recirculation of air. Worn flexible connectors are a common source of leaks and should be inspected regularly. If the damper linkage is out of adjustment, the damper may not be opening completely, thereby reducing performance. If inlet dampers are used, make sure they are installed so that the air is pre-spun in the same direction as wheel rotation. For all dampers, make sure there is sufficient clearance for the blades to open and close completely without hitting the ductwork or other system components. Last, for systems with either pneumatic or electric controls, make sure damper actuators are operating properly. Sharp changes in the direction of airflow at either the fan inlet or outlet will disrupt the flow through the fan and impair performance. If it is impossible to straighten the ductwork entering and leaving the fan, the use of inlet boxes and turning vanes can minimize performance losses.(read

Fans Performance Curves
By: oleg tchetchel
The fan curve presents fan performance. It is one of the most useful tools available during the fan selection process. While multi-rating tables are convenient (see page 12), performance curves offer additional information such as - how much reserve pressure head exists between the design pressure and the peak static pressure, the maximum power the fan might draw, and the efficiency of operation.(read
