Make-up Air System - Tube Ventilator
By: oleg tchechel
When exhaust fans are used to provide ventilation, both for industrial and process exhaust and personnel comfort, a negative air pressure is created within the building. This negative pressure causes several problems:
- Process exhaust systems are less efficient and may not work properly.
- Down flow can occur through gravity vents and result in the back venting of products of combustionfrom flues and stacks of heaters and process equipment.
- Drafts are created that are a dsicomfort to employees. Safe operating of outside doors may even be impaired.(read

Ventilators For Industry
By: oleg tchechel
The manufacturing industry utilizes fans for power boilers, recovery boilers, lime kilns, dissolving tanks, and dryers. These applications, which are integral to the production process, are often very corrosive. Reliability and durability of fans and blowers for such applications are vital for continuous operation. Canada Blower fans for demanding and corrosive applications ofer real value - saving on future downtime and maintenance costs.(read

Ventilation With Industrial Fans And Blowers
By: oleg tchechel
Process fans include several types such as duct fans, roof and ceiling ventilators, wall mounted fans, pressure blowers, and freestanding units with different mounting options. For extreme conditions and plants, drum fans can be used to move even larger amounts of air. These types of fans come with wheels attached and can be rolled to the area that circulation is needed the most. Some manufacturers even sell just the fan heads for a more freedom and a reduced assembly and cost on the company.(read

High Temperature Ventilator And Blower For Up To 2,200 F Operation
By: oleg tchechel
There are 2 major types of high temperature fans - centrifugal and axial:
Centrifugal Wheels:
* Multiblade forward curve wheel. This type of wheel is usually specified where there is a necessity for large volumes of flow against low to medium static pressure requirements. The forward curve blade is that it delivers the same volume of air as either the backward or radial blade wheel, at a lower fan speed, which is important due to wheel stresses at elevated temperatures. This fan is the most common type used in all types of heat treatment operations except where a buildup of material on the blades could occur, as wheel unbalance would result.
* Radial Blade, paddle wheel type fans. This type of wheel is usually specified where there is a necessity for medium volumes of flow against medium to large static pressures. The paddle wheel is considered a self cleaning type of wheel. It could be used where there are various materials or dust in the air stream. Due to its structurally strong design, it is used in many heat treatment applications at very high temperatures where maximum fan longevity is desired.
Axial Blade Wheels:
* The axial blade wheel is usually specified where there is a need for very large volumes of flows against low static pressure. Axial wheel like the multi-blade forward curve type wheel could cause an axial fan to deliver different air volumes at the same static pressure, if the total pressure requirement of the fan system was underestimated. This type of fan is ideally suited where a large volume of flow is required with a minimum of duct work and is used extensively for small and large furnaces, such as aluminum annealing.(read

Big Industrial Forced Draft Fans And Blowers
By: oleg tchechel
Industrial forced ventilation is used to control indoor air quality. Excess humidity, odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates much energy is required to remove excess moisture from ventilation air.(read

Level Three Industrial Fans
By: oleg tchechel
In axial flow ventilator the air must blow in line with the axis of rotation and there must be blades with space between them. With few exceptions, the axial blower or fan must not have a lot of back pressure and will work a lot better if the blade is shrouded. One obvious exception is the turbine compressor used in jet engines, but this requires very tight fittings and very high speed so the air is being rammed in against the outgoing air much faster than it can move - it uses a lot of power and makes a lot of noise. Shrouding works better because the greatest loss in an unshrouded fan is the air coming off near the tips and immediately turning out and back circulating only through the fan and not through the room. The most common shrouded fan people see is muffin style fan in computers. An axial blower can have multiple sets of blades and the blades can even over lap so light is not visible through the fan. Fans are used most often for moving large quantities of air between spaces at atmospheric pressure.(read
