Every year chaff collectors and exhaust ducts catch on fire and cause millions of dollars of damage and injury. A properly installed and maintained EcoFilter prevents the rapid buildup of creosote, oils and other flammable materials inside the cyclone and exhaust duct. There is little to burn and it is wet.
The outside of the cyclone and exhaust stack stay below 140 F, reducing the risk of personal injury. Should you experience a drum fire, it cannot propagate beyond the EcoFilter inlet.
