Each roof requires a good air rinse. Moist air resulting from unfavorable weather conditions must not settle and condense in the roof system. Lomanco® ventilation turbines provide active, continuous and permanent ventilation. Lomanco® Ventilation Turbines are either used preventively or when there are problems when it may be too late. Above all, sheet metal roofs suffer from condensation. And the Lomanco® ventilation turbine can be a solution to condensation problems.
Each panel house must have a well-ventilated bathroom, toilet and kitchen ventilation system. The ventilation can be done through a ventilation shaft where Lomanco® ventilation turbines are located at the outlet. Lomanco® ventilation turbines replace an electric fan that is noisy and often broken. In the ventilation system, we recommend combining Lomanco® ventilation turbines and fans. To regulate ventilation by means of a ventilation turbine, it is advisable to use the control grilles at the outlets in the apartment. For the ventilation of panel house shafts, it is only suitable to use the Lomanco® type LOMANCO® BIB / BEB 14 and the LOMANCO® type LOMANCO® TIB / TEB 14 ventilation head. Ventilation turbines and ventilation heads of other types do not reach the required parameters and do not meet the requirements for ventilation!
The Lomanco® ventilation turbines effectively ventilate the ground, storage, production, cellar and other areas. The Lomanco® ventilation turbine can be controled by manually operated control valve or servomotor.
The Lomanco® BIB 12 and Lomanco® BIB 14 ventilation tubes are a complete product designation (head, adjustable neck and base for unprofilled coverings). The number next to "BIB" then indicates the neck diameter of the given turbine in inches.

The Lomanco® Ventilation Turbines are unrivaled in their proven life-span (development since 1946) and are also highly resistant to the destructive test by faithfully simulating wind gusts on the roof in comparison to turbines on the world market.
In case of extreme weather conditions where a strong wind load is assumed to be high, the Lomanco® BEB14 ventilation turbine or the Lomanco® TEB14 ventilation turbine is designed to withstand wind strength up to 240 km / h. Conventional Lomanco® BIB14 ventilation turbines are certified for speed of wind 195 km / h.
LOMANCO® has tested various turbine materials over time and, as the most advantageous in terms of performance and service life, LOMANCO® aluminum heads (anodised aluminum alloy with increased durability) and a galvanized version (Lomanco® GT 12 ventilation turbine) with a lower life expectancy! The manufacturer's other materials are not used and recommended!

To ensure good air circulation, it is necessary to ensure sufficient air supply to the ventilated space. The rule is that the suction opening must be at least as large as the drain hole under the turbine (turbine diameter). If multiple turbines are used, the suction hole must be the sum of the area of all turbines!
