Correction Factor Table - Industrial Blower Fan

Procedure for Using Correction Factors

The density of air at 70°F and 29.92" barometric pressure (sea level) is .075 lbs./cu. ft. and all Industrial Blower Fan performance tables shown herein have been developed at this standard density. When either temperature or barometric pressure deviates from the

Example: Use of correction factor table for Industrial Blower Fan. Requirement: An Industrial Blower Fan to deliver 9640 CFM at 8" SP at 450°F and 4000 ft. above sea level.

Data needed to fill requirements for Industrial Blower Fan:

Industrial Blower Fan size, BHP and RPM. 1 From the table above, the correction factor for 450°F and 4000 ft. above sea level is 2.0.

above, a change in density obviously results, thus changing Industrial Blower Fan BHP requirements (system capacity and pressure requirements being fixed by design conditions). In order to use standard performance tables to determine correct BHP

2 8" SP (Design S.P.) x 2.0 equals 16" S.P.

(S.P. corrected to 70°F at sea level). 3 Select from performance table an Industrial Blower Fan to deliver 9640 CFM at 16" S.P. Best

selection indicates a No. M21 Industrial Blower Fan,Type I.E. at 1519 RPM and

39.32 BHP. 4 Correct BHP by dividing 39.32 BHP

by 2.0. This equals 19.66 BHP (correct for 450°F at 4000 ft. altitude).

when installation environment involves either or both non-standard temperature and barometric pressure, the following density correction factor table has been developed through applicable physical laws for Industrial Blower Fans.

Recommended selection: NIS-CO Industrial Blower Fan, Size M21: Capacity 9640 CFM, S.P. 8", Temperature 450°F, Altitude 4000 ft.,1519 RPM and 19.66 BHP. Note: Caution should be exercised in selecting the Industrial Blower Fan

motor sizes for operating Industrial Blower Fans handling high temperature air. If the operation of the system is such that there is a build-up period starting with lower temperature air, this will result in the Industrial Blower Fan requiring more horsepower during that period and a motor size should be selected for the most severe condition.

General balancing machines for Industrial Blower Fans. The necessary M Wheels only are good for maximum Housings are made of prime steel weights are arc welded into place tip speed of 18,500 FPM in standard plate, continuously welded, and so that the wheel will always stay in duty construction with heavy duty rigidly braced. Wheels are made balance. After complete blowers are shaft and bearings.

of heavy steel plate, all welded and dynamically balanced. Standard paint finish is baked polyester over phosphatize-cleaned steel. Various corrosion resistant coatings are available — refer to NIS-CO Industrial Blower Fan Catalog No. 35-300 “Special Paints and Protective Coatings.”

Static and Dynamic Balancing

Completed wheel assemblies of all sizes for Industrial Blower Fans are statically and dynamically balanced on electronically controlled assembled, they are all given a running-in inspection and again examined for balance by a portable electronic balancing unit. Inspectors add balance weights to the wheel if necessary to pass a very rigid inspection requirement.

Standard Duty Construction - Industrial Blower Fans

This construction includes standard wheel, housing, shaft and bearing. All wheel types good for a maximum tip speed of 15,000 FPM.

Heavy Duty Construction - Industrial Blower Fans

This construction is available only with the M type wheels and is used for exceptional abrasive conditions. This includes heavy duty wheel, housing, shaft and bearing with a maximum operating limit of 15,000 FPM tip speed.

Industrial Blower Fans are equipped with self-aligning single row ball bearings, double row spherical roller one-piece and two-piece housings.

Computerized selections have been made on all bearings based on radial, thrust and combined loads to give 100,000 average life hours (AFBMA L50) at the maximum design of each Industrial Blower Fan class.

Bearings selected have effective seals to retain the lubricant and to prevent against contamination. All have grease fittings for re-lubrication.

Bearings are available for 400,000 average life hours (AFBMA L50).

For high temperature Industrial Blower Fan application, the inboard bearing is protected by a cast aluminum heat slinger at system air temperatures of 250°F to 600°F, with both bearings furnished with hi-temp grease. Above 600°F, consult factory.

Standards adopted for spark-resistant Industrial Blower Fan AMCA Standard 99-0401-86

Spark Resistant — Type A:

AMCA Standards require that all parts of the Industrial Blower Fan in contact with the air or gas being handled shall be made of non-ferrous material.

Spark Resistant — Type B:

AMCA Standards require that the Industrial Blower Fan to have the wheel and ring about the opening through which the shaft passes of non-ferrous material. Ferrous hubs, shafts and hardware are permitted. Industrial Blower Fans for this condition are furnished with a non-ferrous wheel (except hub and hardware) and a non-ferrous shaft seal around the shaft opening.

Spark Resistant — Type C:

AMCA standards require the Industrial Blower Fan to be so constructed that a shift of the wheel or shaft will not permit two ferrous parts of the Industrial Blower Fan to rub or strike. Industrial Blower Fans for this condition will be furnished with a non-ferrous inlet cone and rubbing plate around the shaft opening.

Note: For all type spark resistant Industrial Blower Fans, the user shall electrically ground all Industrial Blower Fan parts. Either A or B construction conforms to requirements of National Board of Fire Underwriters Pamphlet No. 91 for Industrial Blower Fans handling flammable vapors. Bearings shall not be placed in the air or gas stream. A non-ferrous material shall be any material with less than 5% iron or other material with demonstrated ability to be spark resistant.

The use of these constructions in no way implies a guarantee of safety for any level of spark resistance. Spark resistant construction does not protect against ignition of explosive gases caused by catastrophic failure or from any airstream material that may be present in a system.

Spark-proof construction available in Arrangements 1, 8, 9, and 10 only.

Contact NIS-CO today to find out more about our full line of world class backward inclined blowers to meet all of your industrial blower fan needs. Our backward inclined blowers are used in both commercial and industrial applications and are used all over Canada and the United States. Our Industrial Blowers and Large Industrial Fans come in both Direct Drive Blower and Belt Drive Blower configurations. You can also choose between forward curve blowers and backward inclined blowers, depending on your needs ventilating.com fanblower.com highpressureblower.net industrialblowerfan.com industrialfanblower.net industrialfanblower.com pressureblower.net industrialpressureblower.com tenderall.com chicagoblowercanada.com cbblower.com buffaloblower.com buffalofan.com nis-co.com canadianblower.com olegsystems.com canadablower.com abbblower.com acmefan.net industrialblower.net fansandblowers.net americanblower.net barryfan.com cincinnatifan.net canadafans.com barryfan.net. We also carry a range of centrifugal blower fans which are high rated and high temperature blowers. We also carry a wide range of propeller fans, plenum fans, large Canada Blower industrial fans which can come in both belt drive and direct drive configurations. - Single fan installations are generally less expensive than multiple fan installations. - Multiple fan installations have the advantage of airflow redundancy, i.e. a percentage of airflow will always be available whilst a fan is off line for maintenance or component change out. - Single fan options do not provide any capacity for redundancy airflow The purchase of fan spares. The purchase of spares (motor impeller shafts bearings motor, impeller, shafts, bearings, blades etc) is good management and should be included as upfront capital expenditure.
