Centrifugal Blowers: Essential Industrial Air Handling Solutions
Overview
When it comes to industrial air handling, centrifugal blowers play a crucial role. These devices, alongside PD (Roots-Type) Blowers, Regenerative Blowers, High Pressure Fans, and Airknives, are vital for maintaining air quality in a wide range of industries.
Key Features and Uses
Industrial blowers are primarily used to facilitate air and gas circulation in ventilation systems. They are instrumental in replacing impure or contaminated air with fresh air by propelling it through spaces. From agriculture and chemical processing to automotive and food production, these blowers are essential for tasks such as drying, heat reduction, smoke and odor control, and managing gaseous emissions.
Construction and Materials
Blowers are crafted from durable materials like plastics and metals, often combining both for enhanced performance. In corrosive environments, materials such as polypropylene are preferred due to their strength and resistance to corrosion. Fiberglass is recommended for temperatures above 220 degrees, while metal is suitable for areas requiring pressure above 10 w.g. (water gauge).
Sizing and Applications
The size of a blower is tailored to the environment it serves. Larger units can accommodate both the fan and its power source, while smaller, portable blowers are ideal for temporary circulation or cleanup tasks.
Classification and Specifications
The Air Movement and Control Association categorizes industrial blowers into three classes, based on construction. Specifications in the U.S. focus on factors like airflow in CFM (cubic feet per minute), static pressure, altitude, and air temperature. For example, an application needing 20,000 CFM at 6" wg of pressure may require 12 fans with power ranging from 30 to 60 HP. The ideal configuration involves a 36" wheel powered by a 30 HP motor, capable of achieving air velocities of 2,611 ft/min, whereas smaller configurations provide proportionately lower velocities.
