PLENUM FANS

Acme offers plenum fans in two models; 8800 STAR Series and 8800 Series. Application and performance requirements will determine which model is best suited for your needs.

8800 STAR Series

The 8800 STAR plenum fans are available in arrangements 3H and 3F. Wheel sizes range from 15" - 60" and are constructed of aluminum or steel (steel only on 60") with the single thickness airfoil blades.

The STAR Advantage...

Quiet Operation...The precise orientation of

wheel blades, combined with careful aerodynamic design of wheel and inlet, decreases air turbulence and increases pressure conversion efficiency. The result is a quieter operating centrifugal fan.

Lower Costs...Mixed Flow fan performance but

at ½ the cost and less space. Lower Sound...STAR wheels are designed to

offer significantly lower sound levels in the first three octave bands than those of hollow airfoil wheels while matching the CFM, Static Pressure and RPM of a similar size wheel.

CONSTRUCTION FEATURES

AIRFOIL WHEELS

Shock-free flow at the leading edge of the blades, plus streamlined flow over the blade surfaces, increases wheel efficiency and quietness.

All wheels are statically and dynamically balanced to ensure smooth operation.

AIRFOIL ADVANTAGES...

Steeply Rising Pressure Curve¼

Ensures minimum variation in volume with change in system pressure and provides a pressure reserve above the normal selection range.

Low Operating Cost¼ Maximum

peak and operating efficiencies with minimum power requirements.

Quieter Operation¼

Aerodynamically correct airflow provided by airfoil blading permits quiet operation.

ADD UP TO...

Real Savings¼ low initial cost,

minimum operating expense, and minimum maintenance expense.

Full Value¼ Superior design, workmanship, application and service.

INLETS

Deep streamlined inlets reduce incoming air turbulence and losses to a minimum. Overlapping of the inlet with the contoured wheel rims allows air to move into the wheel without obstruction. Inlets include slip connection.

STANDARD PAINT FINISH

The standard finish for all fans consist of one coat of primer and one overcoat of gray, alkyd enamel paint. Other coatings are available upon request.

HEAVY BEARING SUPPORT - (Arrangement 3)

Heavy steel bearing supports maintain accurate alignment, prevent bearing distortion and offer a minimum of resistance to airflow.

BEARINGS - (Arrangement 3)

Self-aligning, grease lubricated, anti-friction bearings are standard. Minimum starting friction, simple maintenance and long trouble-free life expectancy, make them ideal for fan service. In general, ball bearings are used for the higher speeds, and roller bearings for heavy loads and at slower speeds.

With proper belt tension, ACME bearings are selected for a minimum L of 80,000 hours (L horsepower configurations may lead to reduced bearing life. Information on the actual bearing selection for a given configuration along with bearing life estimates are available upon request.

life

STEEL WHEELS

Wheels have die-formed hollow airfoil blades continuously welded to back plate and rim to provide a rigid assembly for Class I and II applications.

ALUMINUM TABBED WHEELS

Tabbed wheels have die formed aluminum airfoil (hollow on 8800 Series) blades tabbed to backplate and rim for Class I applications. Tabbing eliminates welding distortion improving wheel balance and vibration free operation.

SHAFTS

Shafts are fabricated from medium carbon steel, (larger fans utilize forged shafts) and all are carefully turned, ground and polished to size. All shafts are correctly designed to give safe deflection and operate well below the first critical speeds.

ARRANGEMENT 3

INLET VANE CONTROL (IVC)

Vane control is a simple and efficient means of regulating fan output over a wide range of operating conditions. It combines the advantages of instantaneous regulation of fan capacity (to meet exact pressure and volume requirements of the system) with substantial power savings during those periods when the full rated delivery of the fan is not required. Vanes may be operated automatically or manually without shutting the fan down.

PLENUM FANS

Usable at all times¼ Vanes may be operated

without shutting down the fan ensuring continuous system performance.

Stabilizes Fan¼ Partially closed vanes steepen

the fan curve, minimizing volume variation when the system resistance changes.

Simple¼ Regulating fan output by vane control

permits the use of highly efficient squirrel cage motor and simple starting equipment.

Economical¼ Vane control is a most

economical means of controlling fan capacity combining power savings with low first cost.

Internal (Nested) IVC

with lever

The control of fan output by movable inlet vanes has been accepted as one of the most economical means of varying fan capacity at high efficiency.

Typical Inlet Vane Control Horsepower Curve Illustrating Power Savings.

Inlet Vane Control offers these advantages for Variable Air Volume Systems:

Immediate Response¼ Vane control effects a change in fan pressure and volume without requiring a speed change of either the fan or motor.

Saves Power¼ As the vanes are closed, a reduction in fan output occurs, with a resulting lower motor power input.

Quietness¼ Overall sound level will not increase substantially from full open to the closed vane position.

Present-Future Operation¼ Partially closed vanes permit use of a fan without change for present low occupancy or load. Vanes can be opened as load increases.

SELECTION AND APPLICATION

Efficient fan selection minimizes internal energy losses and sound generation. Fan selections near the peak efficiency provide low sound output consistent with adequate pressure reserve and self-limiting horsepower adding another advantage of carefully coordinated design.

Selection for relatively quiet operation¼ Selection at higher efficiencies minimizes sound generation. For lower sound output, together with other benefits of low power consumption and operating cost throughout fan life, select fans near Normal Selection Curve. When high sound levels are acceptable, together with smaller fans and higher operating costs, selection can be made at lower efficiencies. Under these circumstances, sound attenuation may be desirable.

SELECTION CONSIDERATIONS

Selection of the proper fan for a given application involves not only the operating characteristics of the fan, but a careful analysis of first cost versus operating cost, as well as expected life, quietness of operation, location of equipment and other job limitations. Quite often an analysis of first cost versus operating costs for the life expectancy of the fan can justify a higher initial investment using a larger fan with higher efficiency. Industrial applications have indeterminate life expectancies and often permit smaller fans to be selected at lower efficiencies. Each installation should be thoroughly analyzed in its design stage to insure that the ultimate objective is accomplished.

ACME’S FAN¼ YOUR SYSTEM

Fan selections are based on static pressure capability when handling a given volume of air. The static pressure is calculated for each system by following certain accepted industry practices. This calculation of static pressure is at best an inexact science with the error often compounded by the addition of safety factors.

If the system pressure requirements for a given volume of flow is known, the system characteristic curve is a parabola and can be predicted mathematically. Such a system curve is illustrated to the left.

A fan at a given RPM has a characteristic pressure-volume curve from wide open to blocked tight. Such a fan curve is illustrated to the right.

If the curves are superimposed as illustrated to the left, the intersection is the only point on the system at which the fan can operate. If this balance point does not satisfy the system pressure and volume requirements, the system requirements or fan speed must be adjusted until the required operating characteristics are obtained.

In the selection of a fan to meet calculated or specified pressure-volume conditions, it is important to apply, where possible, an adjustable fan drive with sufficient variation to compensate for variances between actual and calculated operating conditions.

FAN STARTING REQUIREMENTS

A fan is an energy converter. Electrical energy rotates the fan wheel through a driving motor and increases the static pressure (potential energy) of the air handled by the fan in order to overcome resistance to airflow offered by the duct system. The wheel also increases the velocity pressure

(kinetic energy) of the air which is the energy required to maintain the air in motion. The driving motor must be capable of starting the fan from rest and accelerating it to the operating speed with a minimum of disturbance to the electrical system. The information given below is useful in understanding the motor problems that may arise.

To start and accelerate a fan to the operating speed it is necessary to:

1. Overcome bearing resistance. This resistance can

vary with the type of bearing used. It is low for anti-friction types and relatively high for sleeve types.

2. Accelerate the inertia of the fan wheel and shaft.

This inertia is generally designated as the moment of inertia or WR

. The motor must provide energy to accelerate it together with the inertia of the drive sheaves or coupling.

3. Provide energy to the fan wheel as it begins to deliver air into the duct system. The horsepower

required varies with the cube of the fan speed ratio. It is insignificant at low speeds, but increases rapidly as the fan wheel comes up to operating speed.

MOTOR SELECTION CONSIDERATIONS

PLENUM FANS

At lower static pressures it is possible to select motors that are too small. The fan operating brake horsepower could be significantly less than the WR

necessary to accelerate the fan to the point of operation. If the motor was sized to the required operating brake horsepower without consideration for the fan

, drive loss, and bearing loss, then it is very possible to overheat the motor and overload the electrical system. To assure the proper motor size you should refer to the motor manufacturers data.

The job engineer, contractor or representative is responsible for the proper motor size and type selection.

Whenever inlet vanes are used, the starting load and motor heating are reduced, if such devices are kept closed until after the fan has accelerated to operating speed.

CORRECTION OF FAN PERFORMANCE FOR OTHER THAN STANDARD AIR CONDITIONS

Air volumes to be handled by the fan must be calculated to satisfy the application. A fan operating on a given system at a given speed is a constant volume machine. The density of air entering the fan (affected by temperature and/or altitude) can vary, but the air volume delivered will remain unchanged. The system resistance, the fan pressure capability and brake horsepower will vary directly with the air density.

In general practice, the design system resistance is calculated in the usual manner using standard air density and the fan pressure requirements are determined for “standard” conditions. This is sometimes known as the equivalent pressure (SP

Select the fan from the catalog in the normal manner using the equivalent pressure (SP

), noting the fan RPM and BHP. As

indicated by Fan Law #2, the design air volume and selected fan speed will remain unchanged, but the fan pressure and horsepower will vary with the air density. The system resistance will also vary with the air density.

The design of many systems involves the calculation and specification of air quantities by weight as in product drying or combustion. Before a fan can be selected, the air quantity must be converted to an air volume based upon actual air density entering the fan inlet. The system resistance equivalent fan static pressure (SP

) must be determined using the air volume.

The fan selection is now made from the catalog using the calculated air volume and the equivalent static pressure (SP

Fan brake horsepower corrections are made for air density variations as indicated under Fan Law #2C.

FAN LAWS

Two basic fan laws relate performance variables for any fan of a given design (such as the 8800 Series). An understanding of these relationships is necessary to select fans when they are handling air or gas which is different than standard or when fan performance adjustments must be made on existing systems. Both of these laws apply to a

given unchanged duct system.

SAMPLE SELECTION

A 8800 Series size 8837 fan must deliver 27,076 CFM at

4.0 inches static pressure. The fan must perform at an altitude of 5000 feet with an entering air temperature of 150°F.

1. Obtain the density ratio from the table below. For 150°F at an altitude of 5000 feet the ratio is 1.38.

2. Convert the actual static pressure to standard conditions (SP

= 4 in. wg x 1.38 = 5.5 in. wg

3. Use the specified air flow rate and equivalent static pressure (SP requirements from the fan rating tables.

From the fan performance table on page 34, a size 37 fan must operate at 1450 RPM and require 40.97 BHP.

4. The speed is correct as selected from the performance table (when elevated temperatures are involved, compare with the maximum allowable speed of the fan). The power requirements must be converted back to the actual operating conditions by using the ratio of the actual density to standard density.

PLENUM FAN CLASSIFICATIONS

Typically, commercial ventilation equipment is defined by an AMCA Class which relates the ability of a fan to obtain specified air/pressure performance points. These points are defined in AMCA Standard 99-86 for housed backward inclined and forward curved fans. There are no standards for a Plenum fan relating to its performance capability to an AMCA Class.

However, because ACME uses its basic 8100 housed fan airfoil wheel design in our Plenum fans, it becomes convenient to identify Plenum fans by a “ACME Construction Class the normal AMCA Fan Rating Class for the housed 8100 fan line. Therefore, an ACME physically the same as an AMCA

PLENUM FAN OUTLET AREA

A plenum fan does not have a housing to collect the air. Therefore, the traditional concept of an outlet area has to be modified. By definition from AMCA 210, the outlet opening of the wheel is the fan outlet area. This is the circumference of the wheel at the blade tip times the tip width of the wheel.
