    Commercial Duty Plenum FansTwin City Fan & Blowers models EPLFN and EPLQN commercial duty plenum fans incorporate the same performance and quality characteristics of the E-Series plenum fans, but in a lighter duty, more economical design. The EPLFN and EPLQN offer a competitive cost advantage over full-framed plenum fan designs in light to medium duty applications with static pressures of 8.5" w.g. or less.

    The compact direct drive EPLFN and EPLQN offers reduced maintenance by eliminating shafts, bearings and V-belt drives. The EPLFN and EPLQN are a great choice for applications requiring clean airstreams as there is no belt residue in the airstream. The arrange-ment 4 configuration offers space savings with a reduced fan footprint. Different performance points can be achieved either through wheel width reduction or varying motor speeds. Models EPLFN and EPLQN are AMCA certified for Sound and Air.

    EPLFNThe model EPLFN features a highly efficient and cost effective, 9-bladed airfoil wheel design. The high ef-ficiency of the EPLFN will often allow the use of smaller fans without increasing power requirements.

    EPLQNThe Better Sound Quality model EPLQN features a 12-bladed airfoil wheel design that flattens the sound spectrum and reduces the dominance of pure tones.

    Capabilities & Features 14 sizes from 12.4" to 49.0" wheel diameters High efficient 9 and 12 bladed airfoil wheels Class II construction Arrangement 4 direct drive Capacities from 1,000 to 68,800 CFM Static pressures to 8.5" w.g.

    WheelsHigh efficiency, non-overloading airfoil wheels are pro-vided on all EPLFN and EPLQN fan sizes. Aluminum wheels are standard on all sizes. All wheels balanced to level G6.3.

    Inlet ConesHeavy-gauge, spun steel inlet cones are closely matched to the wheel intake rim to ensure efficient and quiet operation.

    Inlet PlateFan inlet cones shall mount to heavy-gauge steel inlet plate. A steel lip suitable for attachment of a boot connector shall surround the unit.

    Construction FeaturesFrameModels EPLFN and EPLQN feature heavy-gauge galvanized or finish painted steel mounting rails and motor mount for strength and rigidity in direct drive applications.

    Mechanical Run TestAll fans are assembled for a mechanical run test and final balance prior to shipment. Vibration readings are taken in the axial, horizontal and vertical direction at the specified speed. Fans are balanced to 0.15 in./sec. peak or less.

    AMCA Sound and Air CertificationModels EPLFN and EPLQN have been designed and tested per AMCA standards. The AMCA logo provides assurance that the fan sound and air levels will match cataloged values.

    Arrangement 4 (Horizontal)Direct drive Arrangement 4 mounts the fan wheel directly onto the motor shaft. This arrangement provides a compact fan/motor unit which eliminates belt residue and requires less maintenance than other arrangements.

    For these reasons, Arrangement 4 plenum fans are widely used in cleanroom, pharmaceutical, and other critical applications.

    Fans can be selected with varying wheel widths to provide desired performance at direct drive motor speeds. Performance changes in the field are usually achieved by means of a VFD.

    Arrangements

    Application InformationPlenum fans are unhoused fans designed to operate inside of field-fabricated or factory-built air handling units.

    The fan wheel pressurizes the entire surrounding air plenum in which the fan is installed, allowing air ducts from any direction to be directly connected to the air handling unit enclosure. This design generally saves space by eliminating the fan housing, transi-tions, and diffusers within the air handling unit.

    Plenum fans have found a ready acceptance in the air conditioning industry. In addition, the construction versatility, adaptability in the direction of the discharg-

    es, suitability for internal isolation and application of sound panels, and generally lower cost makes it a very popular fan arrangement.

    Benefits of a Plenum FanSaves Space There are no housings, transitions, or diffusers within the air handling unit.

    Efficiency Plenum fans can be as efficient or more efficient than scroll type fans at specific operating points towards the bottom of the fan curve.

    Lower cost Plenum fans are less expensive than scroll type fans.

    Protective EnclosureGrill style protective enclosure completely encloses all sides and the back of the fan wheel to protect personnel from moving fan parts. The panels are individually removable to provide access to the wheel for service or inspection. Protective enclosures are plated wire.

    AccessoriesPiezometer Ring (Airflow Measuring System)A piezometer ring is available on plenum fans, as well as other Twin City Fan housed fans, as part of an airflow measuring system, based on the principle of a flow nozzle. The inlet cone of the fan is used as the flow nozzle. The flow can be calculated by measuring the pressure drop through the inlet cone. No tubes or sensors are inserted in the high velocity airstream which could obstruct airflow. The system, consists of a piezometer ring mounted at the throat and a static pressure tap mounted on the face of the inlet cone. A differential pressure transducer and digital display can also be provided. The pressure drop is measured from the tap locat-ed on the face of the inlet cone to the piezometer ring in the throat. The inlet tap is connected to the high-pressure side of the transducer and the piezom-eter ring is connected to the low-pressure side. See diagram below.

    Based on Twin City Fan laboratory tests, the system was determined to be accurate within +/-5%. Refer to Twin City Fan Engineering Supplement ES-105. NOTE: Twin City Fan does not recommend place-ment of flow measuring probes inside the fan inlet cone in the path of airflow. These devices create disturbances and unpredictable performance losses. Twin City Fan will not be responsible for loss of per-formance due to such devices.

    Inlet ScreenHeavy-gauge screen mounted to fan inlet for easy removal.

    Vibration Isolation PadsSpring type vibration isolation mounting pads are available to reduce the transmission of fan vibration in 1" or 2" deflection.

    Application GuidelinesFan Selection Recommendations1. System effect losses (see AMCA 201) and ple-

    num losses should be estimated and added to the required static pressure, prior to making selections. Refer to AMCA Publication 201 at www.amca.org and Twin City Fan Engineering Data Letter Fan Performance Troubleshooting Guide (ED-100) at www.tcf.com.

    2. Fans should be selected so that the point of operation is approximately between 55% and 90% of the free delivery point on the fan curve.

    3. Avoid selections over 4000 RPM. A narrow width, larger size impeller can be used to avoid this.

    4. Where flow monitoring is required, use a piezom-eter ring or externally mounted flow measurement station. Fan performance may be substantially affected by flow measurement probes mounted directly in the fan inlet cone. Refer to page 4.

    5. For direct drive fans without speed control (or where speed control cannot exceed 60 Hz), select fans at 3 5% below the nominal speed of the motor. This will normally cover the uncertainties associated with the system and air balancers measurements. Select motors loaded no closer than 90% of the maximum loading of the motor.

    6. For multiple fans in a plenum, alternate CW and CCW rotation fans to minimize losses. If fans are not counter-rotating, install walls between each fan to create cells in the outlet plenum.

    7. Add losses for duct take-offs per the chart above to pressure requirements of the fan. Bellmouth entries will always reduce losses and are recommended.

    To achieve the air velocity in the discharge duct and overcome the loss associated with the air entering the ductwork, additional resistance must be added to the external static pressure (ESP) requirements of the fan. Different types of duct entrances and locations will require varying correction factors. Therefore, prior to select-ing a fan, make the following correction, depending upon the type of duct and its location.

    ADDITIONAL DUCT ENTRANCE LOSS TO BE ADDED TO FAN ESP

    DISCHARGE TYPE CORRECTION FACTOR

    Duct Entrance Losses From Plenum Fan Cabinet

    Example: A system requires 30,000 CFM at 5" SP at standard air density with one 4 ft diameter duct with bell-mouth placed in a radial discharge. Determine RPM and brake horsepower:

    Flow Parallel To Fan Shaft

    Radial and ducted with bellmouth Radial and ducted without bellmouth Radial without duct or bellmouth Flow parallel to shaft and ducted with bellmouth Flow parallel to shaft and ducted without bellmouth Flow parallel to shaft without duct or bellmouth

    1.1 x Duct Velocity Pressure1.4 x Duct Velocity Pressure1.8 x Duct Velocity Pressure1.6 x Duct Velocity Pressure1.9 x Duct Velocity Pressure2.4 x Duct Velocity Pressure

    Duct area = (42 x ) 4 = 12.57 ft2

    Duct velocity = 30,000 12.57 = 2387 FPM

    Duct velocity pressure = (2387 4005)2 = 0.355 @ std. cond.

    Entrance loss correction factor = 1.1 x duct velocity pressure = 1.1 x 0.355 = 0.39

    Thus, select the fan for = 5" + 0.39" = 5.39" S.P.

    AIRFLOWDIRECTION

    Location and Placement of Fans in Air Handlers1. Center the fan inlets in both the horizontal and

    vertical planes.2. For inlet clearance, see Figure 1. The flow should

    converge at an angle not greater than 45 when approaching the opening for the fan inlet. A minimum of one fan wheel diameter clearance is recommended.

    3. In the fan outlet plenum, a minimum wall clear-ance of one-half fan wheel diameter to the periph-ery of the fan wheel is recommended.

    4. Figure 1 shows that the minimum clearance between the back of the fan wheel and the near-est component downstream (Dim. E) should be one wheel diameter. Small clearances do not allow the flow to equalize behind the fan wheel and the pressure drop of the downstream component is increased.

    5. When the flow enters the inlet plenum perpen-dicular to the fan/motor shaft, large system effect losses can occur. See Figure 2 for a recom-

    mended flow baffle or a vortex breaker that may help preserve rated fan performance.

    6. When two or more fans are installed in a plenum, divide the plenum into imaginary cells of equal area. Center the fan inlets on each cell. See Figure 3.

    Installation Recommendations1. Install the fan so the flexible connector on the inlet

    remains uncollapsed during operation.2. Install thrust restraints (snubbers) to maintain the

    axial position of the fan when it is generating pressure.

    3. Peripheral equipment, such as electrical compo-nents, inverters, control panels, etc., should be positioned away from the high velocity air entering or leaving the fan.

    4. Adjust springs on the isolation base so that spring deflection is approximately equal for all isolators.

    5. Follow safety, installation, start-up, and mainte-nance instructions supplied with each fan.
