GENERAL
Canada Blower roof ventilator shall be mounted with up-blast discharge and include a complete (direct/belt) driven vaneaxial type fan as designed and manufactured by Canada Fans to ensure smooth operation. Fan wheel shall be (steel/aluminum/stainless steel or graphite reinforced plastic-GRP) construction to ensure continuous operation in a hostile environment. Unless otherwise directed, fans shall have the arrangement, motor position and orientation as shown on the layout drawings.
PERFORMANCE (Fixed Pitch or Adjustable Pitch Aluminum Wheel)
Fan ratings shall be based on tests made in accordance with AMCA Standard 210. Flow shall be actual volumetric flow at the fan inlet. Fan static pressure is defined as static pressure at fan outlet less total pressure at fan inlet. Standard inlet density is to be taken as 0.75 lb/ft3 with corrections for temperature, elevation, inlet static pressure, gas composition and humidity as defined in the schedule. Fans shall be selected to operate to the right of the peak static pressure at the given speed to ensure stable performance. Fan brake horsepower shall be equal to or less than specified at the given flow and fan static pressure.
SOUND
Fan manufacturers shall provide sound power level ratings for fans tested and rated in accordance with AMCA Standards 300 and 301. Sound power ratings shall be in decibels (reference 10-12 watts) in eight octave bands. Sound power levels will be corrected for installation by the specifying engineer...dBA or sound pressure levels only are not acceptable.
CONSTRUCTION
Fan housings are to be heavy -- min. 12 gauge, continuously welded construction with flanged and punched inlet and outlet. Ventilator housings with lock seams or spot welded construction are not acceptable.
Canada Blower ventilator windband to be heavy gauge, galvanized steel seam welded. Dampers fabricated of aluminum sheet with flanged edges for rigid performance. Rain tight weather cover furnished for all v-belt driven fans. Roof curb sheet to be heavy gauge steel—at least twice the thickness of the housing with flanged edges to simplify flashing to roof curb and ensure leak proof installation. Aerodynamically designed straightening fan vanes are to be integral to the fan housing. Fan bearing lubrication lines to be extended to a termination point inside the weather cover. Canada Blower ventilator rotors shall be attached to motor shaft by use of split, taper-lock Q-D bushing. A locking plate is bolted to the end of the shaft to ensure safe operation.
BEARINGS (belt driven fans)
Fan bearings are to be heavy duty, grease lubricated, precision anti-friction deep grove ball or spherical roller, self-aligning design. Bearings shall be designed for a minimum L-10 life of 40,000 when rated at the fan's maximum cataloged operating speed ventilating.com fanblower.com highpressureblower.net industrialblowerfan.com industrialfanblower.net industrialfanblower.com pressureblower.net northernindustrialsupplycompany.com 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 pennbarry.net pennfan.net tcffan.com.

SHAFT (belt driven fans)
Fan shafts are to be ASTM A-108 steel, grade 1040/1045, precision turned, ground and polished. Grade 1018 steel is not acceptable. The shaft's first critical speed shall be at least 143% of the fan's maximum operating speed.
PAINT
All fan surfaces are to be thoroughly prepared prior to painting using a combination of washing and hand and power tool cleaning as required in SSPC-SP-3. After cleaning, all surfaces (except wheel if other than steel) are to be coated with industrial grade alkyd enamel. Surfaces of bolted components not accessible after assembly shall be coated and allowed to dry prior to final assembly. Primer only will not be accepted. When a stainless steel fan is specified, steel parts have an SSPC-SP-6 surface preparation and gray epoxy paint is applied.
BALANCE & INSPECTION
All fans shall be precision balanced to ISO quality grade 2.5, report to be submitted with the maintenance manual. A final ventilator inspection by a qualified inspector prior to shipment is required to include: scope of supply confirmation, balance, welding, dimensions, bearings, duct and base connection points, paint finish and overall workmanship.
ACCESSORIES
Fan accessories shall be provided as called for in the plans and specifications. Standard ventilator accessories include:
Motor to be NEMA Design B 3/60/460-575V-1800 rpm, high efficiency TEFC 1.15 SF
V-Belt Drives - Variable Speed/Constant Speed with min 1.5 SF
Belt Guard or weather cover required on belt driven fans
Extended lubrication lines (nylon, copper or stainless steel) with fittings terminating in an
accessible area. (belt driven fans only)
Additional Features that may be required:
Split pillow block bearings
Access Door – bolted/quick opening or plug type with raised door
Companion Flange (angle companion flange bolted to the fan inlet or outlet flange)
Inlet or Outlet screen heavy gauge wire on 1” or 2” centres
Inlet Bell streamlined for smooth air flow, flanged and bolted to the fan inlet
Above 300°F, split pillow block bearings required
Above 500°F, high temperature aluminum paint required
Vibration Isolation - Spring - Rubber-In-Shear
Fusable disconnect – to open the dampers in the event of fire
Square hinged mushroom hood with birdscreen &/or bugscreen &/or filters
Spark Resistant Construction –
AMCA “A” All parts of the fan in contact with the air stream non-ferrous material
AMCA “B” Non-ferrous wheel and aluminum rubbing ring where shaft passes through
Housing with shaft seal and sealed belt fairing
