Velocity Plume Power Venter

The TDF-VP Velocity Plume Power Venter is an innovative plume dilution fan that delivers a powerful vertical plume but also dilutes the flue gas exhaust 100% or more. That means dilution of exhaust condensate, less visible smoke, lower exhaust temperatures etc - all at no additional energy cost or larger motors.

It can be installed outdoors on a roof where it is easily accessible. It works well with any kind of gas-fired and oil-fired boilers and water heaters as well as other applications with high-temperature exhaust air such as generators, solid-fuel-fired ovens, boilers and more. The TDF-VP has the highest temperature rating (1400°F) of any UL-listed Power Venter on the market.
