Pavel Wortha Check

Onesynergy from Ireland were hosted by ThisWeekinFM in the summer as they launched a number of energy efficient and energy production products (including a wind turbine). The latest from the firm is an aerodynamic air ventilation exhaust cowl that can reduce the total energy consumption of an air extraction system by overcoming the inherent inefficiencies of cowls.

Standard cowls impose additional run costs because of the extractor fan’s increased duty to overcome the associated pressure drop. Onesynergy’s Pavel cowl can reduce the energy consumption of the extractor fan by 50%,it is claimed.

In retrofit, the Pavel fits directly onto existing standard ductwork. The patented technology means that it is able to achieve optimum airflow by the gradual deceleration of the air within the unit and its gentle diffusion into the surrounding air at low velocity. Its design means that the fan does not need to work as hard – consequently reducing energy consumption. At current commercial electricity prices, this equates to an average return on investment in under two years.

The Pavel can be assembled at the point of fixing, thus requiring no lifting equipment to raise and position on to the roof. It also requires minimal maintenance as it contains no moving parts.
