Dust Collector Fans

By: Oleg Chetchel

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 - Buffalo Blower manufactures a variety of fan types for dust collectors. Buffalo Blower 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.

In a manufacturing environment, 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.

Laboratories and research facilities exhaust a wide variety of harmful fumes. In concentrated forms, these fumes can be hazardous to human life. Contaminated air must be exhausted in a way that prevents it from returning back into the building, and surrounding locations where people may be present. To effectively exhaust these fumes, which in many cases are corrosive and / or explosive in nature, fans are connected to one or more fume hoods to draw the contaminated air through. For proper ventilation, exhaust fans must be capable of moving air at high velocities to achieve a high plume height, as well as entraining clean ambient air to dilute the chemical concentration in the airstream. Twin City Fan offers a complete line of laboratory & fume exhaust fans for meeting the most stringent industry standards. Our laboratory exhaust fans are often constructed of specialty materials to withstand the fumes associated with these environments.
Induced Draft (ID) fans are used to create a vacuum or negative air pressure in a system or stack. Our centrifugal blowers are used to maintain elevated ventilation, resulting in increased system efficiency. Buffalo Blower can also supply extractor fans, which are typically heavy duty construction to handle particulate in the airstream. In the boiler industry ID Fans are often used in conjunction with FD fans to maintain system pressure which is slightly lower than ambient.

Buffalo Blower has been on the cutting edge of developing fans for over 30 years and has extensive knowledge in conveying all types of materials. Whether you are conveying pet food, sand, paper dust or dried onions, we offer a distinct line of air moving equipment to meet your exact requirements. Based on the bulk density, particle size, horizontal and vertical distances, and your overall system layout, Buffalo Blower can provide the right solution for moving your material. Buffalo Blower also offer a number of options to meet your system requirements whether you need abrasion resistant material or stainless steel with special finishes.

Rail grinding equipment is critical to maintaining railroads and helping to avoid costly replacements. Rail cars equipped with grinding equipment run along the track and remove spalling, shelling and uneven wear due to normal use. Buffalo Blower fans are used to exhaust the grinding debris and to a controlled location of where it is discharged. For this particular application, we provide radial tip fans capable of handling these particulates and offer higher efficiency than our standard radial bladed fans. Blue smoke is a haze of hydrocarbon droplets that hangs in the air. This is produced from truck loading/unloading zones and silo storage. Fans are used in the capture and disposal of scavenger / blue smoke. The smoke can be disposed of by incineration or reclaimed in a mist collection system.
