For many factories and industrial facilities, the Centrifugal Blower is a hardworking team member, making sure that airflow and vacuum are maintained in mission-critical processes. If a Centrifugal Blower is experiencing sub-optimal performance and decreased operational up-time, the culprit may be an often-ignored component of the system – the blower filter.
Why do Centrifugal Filters deserve attention? The filter‘s job is to protect the blower from dust, dirt, and tiny particles floating in the air. A filter safeguards the blower from ingesting particulates and contaminants present in the air. When the filter does its job of protecting the blower and application from debris, it naturally gets clogged up; and over time this prevents the blower from ‘breathing’ properly. With the filter compromised, the blower’s capability is akin to a respiratory system compromised by congestion. Performance suffers, excess heat and vibrations are generated, and the blower becomes much less effective and efficient. The result is a critical scenario that could have been averted with consistent filter replacement.
How Do You Change a Blower Filter?
Centrifugal blower filters need to be cleaned and changed regularly. Luckily, changing the filter on a Republic centrifugal blower is very easy. For most applications and systems, a filter change takes less than 5 minutes.
Watch our video to hear David explain how to change your filter:
Types of Blower Filters
Republic offers both paper and polyester, or “poly,” filter elements for all of our centrifugal blowers.
Paper Blower Filters
Paper filter elements are the most commonly used filter media type but are more susceptible to moisture and tough debris or grime in the application.
Polyester or “Poly” Blower Filters
Poly filters are constructed from woven or layered synthetic polyester fibers. Poly filters are popular due to their durability, as polyester elements are often reusable for a few periods after cleaning.
