How AVIAN Detected a Blower Bearing Failure Before a Baghouse Fire
Estimated damage avoided

Conservative estimate based on avoiding dust collector fire spread, baghouse damage, fire department escalation, cleanup, and production downtime.
- Equipment
- Auxiliary blower and baghouse
- Failure mode
- Bearing failure sending hot material into the dust collector
- Outcome
- AVIAN detected the failure over one hour before the baghouse fire
An auxiliary blower failed catastrophically and shed hot bearing material into the baghouse. AVIAN detected the bearing failure more than an hour before the baghouse caught fire.
What AVIAN Detected
AVIAN thermal monitoring identified the abnormal heat from the failing blower and the risk created by hot material entering the dust collection system. The thermal warning appeared long before the visible fire response window.
Why It Mattered
Baghouses store large amounts of fine dust. Once hot bearing material enters that environment, a localized equipment failure can become a dust collector fire with major cleanup, downtime, and response risk.
For sawmills and planer mills, dust collection and extraction are often among the highest-risk zones. Thermal monitoring can catch upstream failures before they reach the baghouse.
What Changed Operationally
The early alarm gave the site more than just detection at the point of flame. It showed the failure condition upstream, giving the team and emergency responders a clearer window to respond before the fire spread.
If your dust collection system is a critical fire risk, talk to AVIAN about monitoring blowers, ducts, cyclones, baghouses, and connected equipment.
