QIFE Dual Unit

Twin City Fan & Blower offers a specially modified version of the QSL fan designated as “QIFE” for induced flow laboratory fume hood exhaust applications, available in sizes 90 through 542.

The QIFE fan consists of a vertically mounted QSL unit with one of three different nozzles and specially designed windband to maximize dilution ratio (overall outlet volume/lab outlet volume) and plume height.

Mounted on a modular designed mixing plenum box or curb cap, the QIFE is capable of generating an induced flow to meet stringent roof exhaust requirements.

QIFE fans in a standard configuration utilize a heavy-duty curb cap. An optional modular mixing plenum box includes an integrated curb cap.

Benefits of Mixed Flow FansTwin City Fan & Blower Type QIFE Mixed Flow Induced-Flow Fans combine the benefits of axial flow and centrifugal flow fans with the added benefit of entraining ambient air for a pre-diluted plume. The QIFE has the advantages of an axial fan in its com-pact design and straight-through airflow combined with a centrifugal fan’s preferred acoustical character-istics and high pressure capabilities. QIFE fans offer superior air and sound performance and the AMCA certified rating seal for air and sound.

ApplicationThe QIFE Induced Flow Mixed Flow Exhaust Fan is intended for use in exhausting laboratory fumes and hazardous chemicals in such a manner that diminish-es the likelihood of concentrated, contaminant-laden air from being re-entrained into the building's intake or makeup air. This unit is commonly used in exhaust systems for universities, schools, hospitals, research facilities, laboratories, restaurants and waste water treatment plants.

Induced flow exhaust fans dilute contaminated air at the outlet as well as increase the outlet volume of the fan. This accelerates the discharge air, increasing plume height without a tall stack.

Wheel DesignThe QIFE impeller is designed with die-formed, continuously-welded single-thickness or airfoil blades for a stable air performance throughout the operating range. The impeller is statically and dynamically bal-anced prior to assembly and rechecked for balance after assembly by Twin City Fan & Blower.

Bypass AirAmbient air that is drawing through the bypass air plenum and mixed with the lab exhaust to increase dilution and plume rise. Bypass air is primarily used in variable volume applications to maintain a constant discharge volume.

Dilution RatioThe ratio of the total fan outlet volume to the lab exhaust volume. (Total Volume/Lab Exhaust Volume).

Entrainment AirAir that is entrained (induced flow) through the wind-band and mixed with the lab exhaust to increase the dilution ratio and plume rise.

Fume ExhaustCaustic or noxious air that is being exhausted from laboratory or fume hood.

NozzleDevice located internal to the fan housing, providing fume exhaust air to accelerate upon entrance to the windband. Three nozzles per fan size are available on the QIFE; low-velocity, medium-velocity and high-velocity. Each nozzle provides different flow charac-teristics. Nozzle should be selected based on the application requirements.

Plume RiseThe height of the fume exhaust and entrainment air above the discharge of the windband.

Plume HeightOverall height of the discharge plume rise, plus the added height of the exhaust system above the roof-deck level. (See diagram below).

Total AirflowThe total airflow exiting the windband, including fume exhaust, bypass air, and entrainment air.

WindbandDevice used to direct the fume exhaust as it leaves the housing of the exhaust fan and entrain dilution air. Also available with an acoustically attenuated option.

The following illustrations describe the procedure for determining the total laboratory exhaust fan discharge flow. The total discharge flow is the sum of inlet airflow and entrained airflow. The key requirement to AMCA 260 is the variable resistance box. This box allows the measurement of total discharge flow (Ps = 0 in. w.g. to simulate discharging the fan to atmo-sphere) at all points along its fan curve.

Without the variable resistance box, the entrained airflow can only be measured at the free air point of its fan curve. The entrained airflow obtained can be used to calculate an effective plume height. Therefore, AMCA 260 certification is necessary to ensure the laboratory exhaust fan specified is providing the plume rise and entrainment submitted.

Type QIFE Induced Flow Exhaust Fans, where indicated on drawings and schedules, shall be of the non-over-loading design, and shall be of the size and capacity as indicated in the fan schedule. Induced flow exhaust fans shall be as manufactured by Twin City Fan and Blower, Minneapolis, Minnesota.

Fans shall be designed for maximum efficiency. Fans shall have a sharply rising pressure characteristic extending through the operating range and continuing to rise well beyond the efficiency peak to assure quiet and stable operation under all conditions. Horsepower characteristics shall be truly self-limiting and shall reach a peak in the normal selection area.

PERFORMANCE — Fans shall be tested in accordance with AMCA test codes for air moving devices and shall be guaranteed by the manufacturer to deliver rated published performance levels. Model QIFE shall be licensed to bear the AMCA certified ratings seal for air, sound and induced flow. Sound certification shall apply to both inlet and outlet sound power levels. Model QIFE shall be UL/cUL 705 listed for electrical.

HOUSING — Housings shall be cylindrical and welded steel throughout. Inlets shall be fully streamlined. Housings shall be suitably braced to prevent vibration or pulsation. Totally enclosed weather cover shall enclose motor and V-belt drives. Punched inlet flange shall be equipped for curb cap or mixing plenum box mounting. Extended lube lines shall be provided for ease of lubrication. Model QIFE shall include outlet nozzle, windband, heavy duty coated steel curb cap, access door, shaft seal and weather cover, and a sealed belt tube for the protection of belts and drive components from the airstream.

WHEEL — Fan wheels shall have die-formed blades designed for maximum efficiency, and quiet and stable operation. Blades shall be continuously welded to the back plate and wheel cone. Wheels shall be statically and dynamically balanced and the complete fan assembly including motor and drive shall be test balanced at or near the operating speed at the factory prior to shipment.

SHAFT — Shafts shall be AISI 1040 or 1045 hot rolled steel, accurately turned, ground, polished, and ring gauged for accuracy. Shafts shall be sized for the first critical speed of at least 1.43 times the maximum speed.

BEARINGS — Bearings shall be heavy duty, grease lubricated, anti-friction ball or roller, self-aligning, pillow block type and selected for a minimum L-10 life of 200,000 hours at the maximum fan RPM. Bearings shall be equipped with extended lubrication lines with grease fittings outside of the fan housing.

DRIVE — Motor sheaves shall be cast iron, variable pitch on applications 10 HP and smaller, and fixed pitch on 15 HP and larger. Drives shall be sized for at least 200% of motor horsepower.

CURB CAP — A heavy-duty, coated steel or galvanized curb cap shall be included to provide for a weather-tight transition between the roof curb and the fan. The curb cap shall allow discharge height up to 10 feet from roof without the need for guy wire support.

NOZZLE AND WINDBAND — A nozzle and windband combination shall be provided to efficiently induce ambi-ent airflow from outside the fan housing and increase discharge velocities to be a recommended minimum of 3,000 FPM without significantly affecting BHP requirements. The windband shall provide a minimum discharge height of between 84" and 120" from roof surface.

WEATHER COVER — A raintight, easily removable weather cover shall be provided to completely enclose the motor and exposed parts of the V-belt drive.

OPTIONAL ACCESSORIES — Where required the fans shall be provided with:• AMCA “B” or “C” spark resistant construction• Modular mixing plenum box• Bypass damper with actuator• Isolation damper with actuator• Disconnect switches• Roof curb• Vortex breaker• Special coatings (Epoxy, Air-Dry Phenolic, Synthetic Resin) on airstream parts or entire unit• Special materials of construction

SUBMITTALS — Submittals for approval of equipment shall include copies of outline drawings, AMCA Certified Ratings, and percentage pressure-volume performance curves showing point of operation.

GUARANTEE — The manufacturer shall guarantee the workmanship and materials for its QIFE Mixed Flow Induced Flow Exhaust Fans for three (3) years from shipment.
