Unhoused Plenum Fans were developed in response to thecontinuing push for greater system value and applicationflexibility in air-handler systems. For systems utilizing pres-surized plenums, these fans provide the airflows and pres-sures of conventional housed fan designs but in compact,more economical configurations. The result is reduced sizeand weight of air-handler cabinetry with maximum appli-cation flexibility. System air is supplied or returned to theair handler from virtually any direction with a minimum ofductwork. Plenum Fans offer system manufacturers theutmost in choice of sizes and configurations.

ACCESSORIES AND MODIFICATIONS

Safety accessories are available from nyb, but selection of the appropri-ate devices is the responsibility of the system-designer who is familiarwith the particular installation, or application, and can provide for guardsfor all exposed moving parts as well as protection from access to high-velocity airstreams. Neither nyb nor its sales representatives is in a posi-tion to make such a determination. Users and/or installers should read“Recommended Safety Practices for Air Moving Devices” as published bythe Air Movement and Control Association, Arlington Heights, Illinois.

VARIABLE FLOWAPPLICATIONS

PAGE 5

The rising cost of energy requires that air-handling sys-tems be operated efficiently at less than maximum designairflow. The high efficiency and inherent stability of theAcoustaFoil wheel is particularly well-suited to variableairflow systems. The AcoustaFoil wheel design ensuresnot only maximum operating efficiency at design CFM but also at reduced airflow regardless of the controlmethod applied. This higher efficiency allows quieteroperation throughout the modulation range.

The New York Blower Company’s nationwide network oftrained sales engineers is familiar with each of these con-trol alternatives and can offer further assistance in select-ing the best control for a particular application.

INLET-VANEDAMPER CONTROL

Inlet-vane dampers affectthe fan’s output by spin-ning the air in the direction of wheel rota-tion. With this prespin,the wheel cannot developits full output, yielding areduced CFM at reducedhorsepower. Each dampersetting creates new pres-sure and horsepowercurves. With inlet-vanedampers, reduced airflowalways results in reducedhorsepower.

VARIABLE FREQUENCYMOTOR SPEEDCONTROL

Variable frequency motorspeed controllers provideenergy savings by directlycontrolling fan speed.From the fan laws, CFMvaries directly with thechange in fan speed andhorsepower varies by thechange in fan speedcubed. For example, a20% reduction in fanspeed yields a 20%reduction in airflow and a49% reduction in BHP.Controllers must havelockouts to prevent opera-tion beyond the maximumsafe speed of the fan.

HOW TO USE CAPACITY TABLESEXAMPLE: A fan is required for 3200 CFM at 41⁄2”WG at 100°F. and at 1000 ft. elevation. Plenum discharge

is radial with a 2 ft. x 2 ft. duct with no transition.

Select size, RPM, and BHP of fan from capacity tables.

For conditions other than standard, correctstatic pressure for actual altitude and tem-perature using Chart II.

Correct system static pressure for lossesassociated with the discharge from theplenum using Chart I.

Determine actual performance at operatingconditions by correcting SP and BHP.

Check maximum safe speed of fan at tem-perature using Chart III.

Chart I gives a 1.4 velocity pressure correction factor for radial discharge,no transition. Duct velocity is CFM ÷ duct area. 3200 CFM ÷ 4 = 800 FPM.Velocity pressure = (duct velocity ÷ 4005)2. (800 FPM ÷ 4005)2 = .04”WG.Correction is velocity pressure x correction factor, .04” x 1.4 = .06”WG.Static pressure required = 4.5”WG + .06”WG = 4.56”WG.

Chart II gives a 1.10 factor for 100°F and 1000 ft. Corrected SP is 4.56”WGx 1.10 = 5.0”WG at 70°F. Select fan from capacity tables for 3200 CFM at5.0”WG.

A Size 133 is selected for 3200 CFM at 5.0”WG at 3921 RPM and 4.87BHP.

Actual performance: 3200 CFM at 4.56”WG [5.0 ÷ 1.10] at 3921 RPMat 4.43 BHP [4.87 ÷ 1.10] at 100°F. and 1000 ft.

From the capacity table and Chart Ill, the maximum safe speed of a Size133 fan is 4287 RPM [4330 RPM x .99]. A Class II fan is satisfactory foroperation at 100°F.
