BI & BIA Industrial Centrifugal Fans Aerovent s BI and BIA Centrifugal Fans feature efficiently designed backward inclined wheels for industrial air moving applications. Designed for clean air applications, the BI and BIA fans offer energy savings and operate at lower noise levels than other industrial fan types. One of the most common uses for a BI fan is on the clean air side of a dust collector. An industrial fan is essential in a dust collector system. It induces the flow to move the contaminants through the system. A dust collector system can be designed with the fan upstream, clean air side, or downstream, dirty air side. For a particular application, each will have its advantages and disadvantages. If the system has the fan installed on the clean air side of the dust collector, where little or no dust is present, a more efficient fan can be selected. If the system has the fan installed on the dirty air side of the dust collector, a material handling fan must be selected. he BI fan can be installed on the clean air side of a dust collector system. his installation design will minimize blade erosion and reduce energy costs compared to installing a material handling fan on the dirty air side. A material handling fan emphasizes ruggedness and durability in its design, not efficiency, for heavy material loading. Due to continuous dust flow through the fan, the fan blades will eventually erode, requiring wheel replacement. A BI fan, however, emphasizes efficiency in its design, thus providing energy savings. By installing a BI fan on the clean air side of the dust collector, where little or no dust is present, blade erosion is also minimized, reducing maintenance costs. Note that although the BIA fan is more efficient, it should never be used in dust collecting systems.

Performance Correction For emperature & Altitude Fan Calculations For Elevated emperatures at Sea Level When a fan operates at standard conditions, it is handling air at 70 F as measured at sea level. If the performance of the fan is based on standard conditions, the fan can be selected directly from the performance tables in this catalog. When a fan operates at temperatures other than 70 F, a temperature correction factor is utilized to convert the operating conditions to standard conditions. his conversion must be done before the fan can be selected from the performance tables in this catalog. After the fan is selected at standard conditions, the temperature correction factor is utilized again to convert the standard brake horsepower to the operating brake horsepower. his is shown in the example below. he temperature correction factors are found in able 1. Example: he contractor specifies a 20" centrifugal fan with a BI wheel, in Arrangement 1, to provide 6,660 CFM at 3 1 2" SP, at 600 F (0.0375 lbs./cu. ft. density) at sea level. For 600 F, able 1 shows a temperature correction factor of 2.00. sing the temperature correction factor, the static pressure at standard conditions is determined as follows: Operating x emp. Correction Static Pressure Static Pressure Factor = at Std. Conditions 3 1 2" SP x 2.00 = 7" SP at Standard Conditions urn to page 14 for the 20" BI fan performance table. sing 6,660 CFM at 7" SP at standard conditions, find the RPM and brake horsepower to be 2404 RPM and 10.3 BHP. Note: 10.3 BHP is the brake horsepower required at standard conditions and is also referred to as the cold brake horsepower or starting brake horsepower. he actual brake horsepower at the operating condition of 600 F and sea level is determined by the following equation: Brake HP at Std. Conditions Brake HP at Correction Factor = Operating Conditions 10.3 = 5.47 BHP at Operating Conditions 2.00 herefore, the 20" BI fan providing 6,660 CFM at 3 1 2" SP, at 600 F will run at 2404 RPM and will require 5.47 BHP at operating conditions and 10.3 BHP at starting. When operating at temperatures other than 70 F, the maximum speed of the fan class is affected. o determine the maximum speed at the operating temperature a maximum safe speed factor is applied to the maximum speed of the class. able 2 shows the maximum safe speeds for BI wheels at 70 F and able 3 shows the maximum safe speed factors for elevated temperatures. For this example, assuming steel construction, the maximum safe speed factor is 0.2. a. he maximum Class I RPM is 141 RPM. In this example the operating RPM, 2404 RPM, is greater than 141 RPM. A Class I fan cannot be utilized. b. he maximum Class II RPM is 2523 RPM. Applying the maximum safe speed factor: 2523 RPM x 0.2 = 2321 RPM For this example, the operating RPM, 2404 RPM, is greater than 2321 RPM. herefore, a Class II fan cannot be utilized. c. he maximum Class III RPM is 3202 RPM. Applying the maximum safe speed factor: 3202 RPM x 0.2 = 246 RPM Since 246 RPM is greater than the operating speed of 2404 RPM, a Class III, 20" BI fan can be utilized. able 1. emperature Correction Factors ( F) EMP.

Performance Correction for emperature & Altitude Fan Calculations For Altitudes Other han Sea Level at 70 F When a fan operates at 70 F but at an altitude other than sea level, an Altitude Correction Factor is utilized to convert these conditions to standard conditions. he conversion must be done before the fan can be selected from the performance tables in this catalog. After the fan is selected at standard conditions, the altitude correction factor is utilized to convert the standard brake horsepower to the operating brake horsepower. his method for correcting altitude is the same as for temperature except the altitude correction factors are found in able 4. able 4.

After the fan is selected at standard conditions, the temperature and altitude correction factor is utilized to convert the standard brake horsepower to the operating brake horsepower. he emperature And Altitude Correction Factor is calculated as follows: emp.

From able 4, the altitude correction factor for 3000 feet above sea level is 1.12. c. herefore, 1.72 x 1.12 = 1.3 For 450 F and 3000 feet above sea level, the emperature & Altitude Correction Factor is 1.3. able 5.

Corrosion Resistance Corrosion problems result when the air contains one or more chemicals which are corrosive in nature. he extent of the corrosion problem, however, varies with the specific properties of the chemical involved, the concentration, moisture content, and temperature of the mixture. Protective coatings and special construction are available to combat corrosion problems. Spark-Resistant Construction Described below are three classifications as defined by AMCA Standards for spark resistant construction. ype A B C Construction Details All parts of the fan in contact with the air or gas being handled shall be made of nonferrous material. Steps must also be taken to ensure that the wheel, bearings, and shaft are adequately attached and/or restrained to prevent a lateral or axial shift in these components. he fan shall have a nonferrous wheel and nonferrous ring about the opening through which the shaft passes. Ferrous hubs, shafts, and hardware are allowed provided construction is such that a shift of wheel or shaft will not permit two ferrous parts of the fan to rub or strike. Steps must also be taken to ensure that the wheel, bearings, and shaft are adequately attached and/or restrained to prevent a lateral or axial shift in these components. he fan shall be so constructed that a shift of the wheel or shaft will not permit two ferrous parts of the fan to rub or strike. NOES: 1. No bearings, drive components or electrical devices shall be placed in the air or a gas stream unless they are constructed or enclosed in such a manner that failure of that component cannot ignite the surrounding gas stream. 2. he user shall electrically ground all fan parts. 3. For this standard, nonferrous material shall be any material with less than 5% iron or any other material with demonstrated ability to be spark resistant. 4. he use of aluminum or aluminum alloys in the presence of steel, that have been allowed to rust, requires special consideration. Research by the.s. Bureau of Mines and others has shown that aluminum wheels rubbing on rust steel may cause high intensity sparking. he use of the above standard in no way implies a guarantee of safety for any level of spark resistance. Spark resistant construction also does not protect against ignition of explosive gases caused by catastrophic failure or from any airstream material that may be present in a system. 8 Aerovent Bulletin 71
