Fan Performance Curves   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.(read entire article)

Fiberglass Blower Fan   By: Oleg Tchetchel
Potential applications for FRP fans include any process in which corrosive fumes must be captured, moved, cleaned, or vented. FRP fans are most often used in fume-scrubber systems where the scrubber itself may be constructed of FRP or an exotic alloy, but where FRP is the preferred fan material. Galvanizing and etching processes often have FRP exhaust hoods and ducts, and many of the fans used to convey fumes in such systems are also built of FRP. Waste water treatment plants and laboratory exhaust systems are other applications for which FRP fans are being used with increasing frequency.(read entire article)

Frp Blower Fans   By: Oleg Tchetchel
Industrial process applications involve a wide variety of corrosive gas streams. Selecting the best materials of construction for air handling equipment can be difficult. This article provides information about the corrosion resistance of the resins used to manufacture standard FRP fans.(read entire article)

Heavy Duty Mix Flow Ventilators   By: Oleg Tchetchel
Mix flow ventilators combine characteristics of both axial and centrifugal fans, and in the Industrial Pressure Blower Co. (New York) design the impeller resembles a fixed pitch axial fan. Industrial Pressure Blower Co. (New York) has two ranges of mixed flow fan: one heavy duty, ideally suited for handling dust-laden gases, and a compact range that gives higher pressure rises than can be obtained from similar sized axial fans.(read entire article)

High Temperature Exhaust Ventilators   By: Oleg Tchetchel
High temperature exhaust fans can be grouped into two general categories: emergency smoke evacuation and process ventilation. Generally speaking, emergency smoke evacuation fans may never be used, but they must be installed and be capable of exhausting high temperature air and smoke in the event of a fire. In contrast, high temperature process ventilation requires continuous duty exhaust of high temperature air, fumes or particulate. Both application types are uniquely different requiring special construction and system design considerations. In this article, we will examine both types of exhaust applications, looking first at the emergency smoke exhaust category. Since emergency smoke exhaust deals with lifesafety issues, there are governing bodies in place that identify and regulate specific design and performance standards. The administration and organization of the various governing bodies is subject to modification based on the needs of the industry. Currently, four such agencies are Industrial Risk Insurers (IRI), Southern Building Code Congress International, Inc (SBCCI), the National Fire Protection Association (NFPA), and Underwriters Laboratories, Inc. (UL). IRI insures properties all over the world based on an informational manual, which details the construction requirements that belt drive emergency heat and smoke exhausters must meet in order to be covered by IRI.(read entire article)

High Temperature Fan Blowers   By: Oleg Tchetchel
The fan engineer must understand the limitations of materials and various failure mechanisms, such as high stress, stress to rupture, and creep. Sometimes, it is necessary to consider high cycle fatigue, low cycle fatigue in cyclical operation with speed changes, and numerous start-stop cycles. If rapid temperature changes are encountered, transient analysis may be required due to thermal stresses.(read entire article)

High Temperature Ventilators And Blowers   By: Oleg Tchetchel
A common variation to the standard fan design is the addition of insulation. The bearing mounting plate, bearing cover and belt tube are the most likely components to be insulated for a high temperature application. Buffalo Blower Co. automatically includes insulation for these components on all fans specified with either HT Option III or HT Option IV.(read entire article)

How To Increase Blower Performance   By: Oleg Tchetchel
A fan cannot perform as designed if the air flow surfaces are distorted by contaminants. Even in large fans, a sixteenth of an inch of build up can reduce performance. Centrifugal fans will move some air even when running backwards. While some types would use so much horsepower they would trip circuit breakers, other design s could run for years without being detected. Fan components may be out of position due to routine cleaning or painting or the wheel could have shifted during shipment.(read entire article)
