Keller Benefits

The ProVent features the following benefits: 

With the ProVent, safety zones can be significantly reduced. 

For instance, the safety zone on a Vario eco dust collector without ProVent is 16.5' (5m). 
With the ProVent unit installed on the Vario eco, this safety zone can be reduced from 16.5' (5m) to 2' (0.5 m).

With the new shock pressure resistant protection shaft, the ProVent is able to absorb shock wave and intense heat.
