Commercial Ventilating Fan   By: oleg tchetchel
As a rule, the factory's ventilation equipment is inadequate for anything more than safeguarding the health of the occupants. In some cases, it does an inadequate job of this. 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. The most effective way to incorporate wall or roof exhausters into a system will be discussed below. A large number of buildings use exhaust fans and/or power roof ventilators to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure.(read entire article)

Duct Fans Ventilators   By: oleg tchetchel
Tenderall Fan axial flow 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 entire article)

Energy Recovery Fan Blowers   By: oleg tchetchel
Combining outdoor air and exhaust air ventilation functions into a single unit help drive an important practice in good HVAC design-building ventilation balance. In layman's terms: What goes in must come out. Traditionally, the outdoor air needs and the exhaust air needs were calculated in separate thought processes. The designer would specify the minimum outdoor air and exhaust air volumes required by code, but would stop short of comparing the totals to check the ventilation balance. Frequently, this led to over pressurized buildings where doorways were transformed into wind tunnels. In some cases, buildings became negatively pressurized and infiltration made indoor climate control difficult.(read entire article)

Fan Blower Performance Curve   By: oleg tchetchel
Fan curves are based on laboratory test data and are sometimes referred to as "test curves". A typical test curve will often define the performance parameters for a specific design and size of fan, operating at a given speed, moving a gas of a given density. Inspection of this graph will show that it is actually composed of four separate curves.(read entire article)

Fans And Blowers   By: oleg tchetchel
Methods of plants ventilation are: * Exhaust fans or Power 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. * Supply Fans or PRVs. A large number of buildings use exhaust PRVs to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure. The solution to the problem of this kind is usually found in the use of supply fans or "make-up" air ventilators.(read entire article)

Fans For Dust Collector   By: oleg tchetchel
Fans are an essential part of every dust collection system and are used to assist in controlling and conveying dust for numerous applications. Whether you are capturing welding smoke or sawdust - Tenderall Fan manufactures a variety of fan types for dust collectors. Tenderall Fan offer backward inclined fans for use on the clean side of a filter, radial bladed fans for cyclone applications, and an extensive line of top mounted and side mounted units. A HEPA filter is a specific filter defined by the United States Department of Energy. Commonly used in clean rooms for the biomedical, pharmaceutical, and electronic microcircuitry industries, these filters are designed to ensure very high standards of air quality and prevent contamination. Our fans are used in these systems to force supply and exhaust air through the HEPA filter and prevent process contamination. Intake filtration is especially important in industries such as electronic microcircuitry, while exhaust filtration is used to restrict external contamination in biohazard and radioactive material handling.(read entire article)
