We have introduced a new line of ventilation fans called the B series. We have resigned the bracing to minimize the flex with in the fan frame. This added rigidity will cause our fans to last longer than all others, adding value and reducing your overall ventilation costs. Our fans are quieter with less vibration then any of our competitor's fans. You can hear and feel the difference.

Interesting fact: we have been selling quite a few fan blades to replace worn out and failing blades on competitive fans. Save yourself time, future headaches and money in repairs by purchasing BERG quality right away!
