Industrial Wall Exhaust and Supply Fans (propeller panel ventilators)

Canada Blower axial flow panel fans are designed for low pressure building ventilation, room ventilation, industrial ventilation, commercial ventilation and industrial process application. Typical applications include heat, smoke, and fume removal; process ventilation and process air handling; proces drying with ambient or preheated air; comfort process cooling and general ventilation of buildngs. Available in direct drive arrangement 4 and corresponding belt drive arrangement 9. Sizes from 6 thru 96. Capacities: to 350,000 CFM. Static pressure to 2.5 inches water gauge.

Axial Filtered Air Vents: used primarily in industrial facilities to supply filtered air to spaces housing personnel and electrical and/or electronic equipment. Available in 'draw-thru', or 'blow-thru' configuartions, with removable filter housing cover and easy-clean filters.

Spark Resistant X-proof construction: wall fan for non-sparking x-proof applications is supplied in AMCA A (all aluminum or monel airsteram), AMCA B (aluminum wheel, or monel wheel), or AMCA C (buffer type) spark resistant construction.

The size of the industrial fan is often overlooked when selecting a fan system for a new or replacement industrial application. Generally, industries use oversized fans to accommodate for uncertainties of future requirements. While some moderate oversizing is typically acceptable, choosing an excessively large equipment than the actual system requirement should be avoided. The size of the centrifugal fan should be optimal to the anticipated normal demand where it can operate at maximum efficiency for a given volume of air. Proper sizing of the fans involve determining all aspects of fan efficiency including airflow requirement and system effects at the fan inlet and discharge.

Key Factors That Effect Fan Sizing

Airflow Requirement

The actual volume of the air required depends on the application need. If the required air volume and static pressure that the fan must overcome are known, then the fan can be selected with optimal size which can operate near to the point of maximum efficiency. However, if the application demands variable airflow volumes, then it is less likely to select a proper fan size because of the varying system conditions. In such cases, volume control methods such as VFDs (Variable Frequency Drives) are used where the fan rotational speed will control the air volume and static pressure to match with the system demand.

System Effects

In applications with widely varying operating conditions, vanes and ducts are used to alter or control the airflow at the inlet and discharge. Centrifugal fan systems will have difference in performance than as rated due to the system effect developed by these air control devices. In order to compensate for the losses in the airflow due to system effect, often industrial applications are designed to use oversized fans. If a larger fan size is selected, the fan operation can become significantly inefficient. It causes the fan to have stall or surge in rotation during minimum volume demand, resulting in excess low frequency noise and waste of energy.
Necessity to Avoid Using Over-Sized Centrifugal Fans

High Energy Consumption

Not all industrial applications require larger air volumes for their industrial process. Having too much airflow can be counter productive for some industrial applications and may even drive up the energy consumption and cost. Since oversized fans come with large sized motors which consume more power than the moderate ones, it is better to use an optimal fan size that is suitable for current demands of the process.

Delivers Poor Performance

To avoid under performing systems in industrial and commercial applications, fans are oversized for their service requirements. Under such conditions, fans do not operate at their best efficiency because they generate excess airflow and have system performance problems. High airflow can cause unstable fan conditions resulting in increased noise and system vibration ultimately leading to degraded fan performance.
