GENERAL
The Canada Blower mixed flow inline fan shall be designed and manufactured by Canada Fans to ensure smooth operation. Fan wheel shall be all steel construction complete with truncated cone shape hub and conical shroud to ensure continuous quiet operation. Unless otherwise directed, fans shall have the arrangement, motor position and orientation as shown on the layout fan drawings.
PERFORMANCE
Canada Blower fan ratings shall be based on tests made in accordance with AMCA Standard 210 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. 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
Canada Blower fan housings are to be heavy -- min. 12 gauge, continuously welded construction with flanged and punched inlet and outlet. Housings with lock seams or spot welded construction are not acceptable.
| Size | Thickness |
| 300 & 400 | 14 gauge (0.0747” – 1.9 mm) |
| 500 – 700 | 12 gauge (0.1046” – 2.7 mm) |
| 800 | 10 gauge (0.1345” – 3.4 mm) |
| 1000-1200 | 7gauge (0.1793” – 4.6 mm) |
Aerodynamically designed straightening vanes are to be integral to the fan housing. Canada Blower fan impellers shall be attached to motor shaft by use of split, taper-lock Q-D bushing.
BEARINGS (belt driven fans)
Fan bearings are to be heavy duty, grease lubricated, precision anti-friction spherical roller, self-aligning design. Fan bearings shall be designed for a minimum L-10 life of 100,000 when rated at the fan's maximum cataloged operating speed.

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) 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.
BALANCE & INSPECTION
All fans shall be precision balanced to ISO quality grade 2.5, report to be submitted with the maintenance manual. A final blower 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
Accessories shall be provided as called for in the plans and specifications. Standard fan 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 Fan Features that may be required:
Square end panels 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 2” centres Above 500°F, high temperature aluminum paint required Vibration Isolation - Spring - Rubber-In-Shear Exterior acoustic wrap with satin coat steel skin Spark Resistant Fan Construction –
