RE: The new Electric VioFan or EVF from BVM
But I think BVM will be selling more EVF units than DS 94 or TF-4000. Also parts and service will be alot easier. The DS-94 does not take much abuse. Very easy to damage the shroud. I have owned 4 of the DS-94 fan units. I will be replacing some of them with the EVF.. To used the DS-94 or TF-4000 in an existing BVM jet a number of mods need to be done. With the EVF no changes are required.
