Roof-AM-HT line is designed to extract large volumes of air in roof installations, also in case of fire emergency where it is prescribed the necessity to guarantee the smoke extraction in environments as car parks, commercial centers, hospitals, theatres, museums, buildings etc. 

Roof-AM-HT fans have been designed and manufactured according to the European Directive EN 12101-3 obtaining the certification from an authorized autonomous certification body. This line is suitable to work in continuous at the temperature of 50°C and in case of emergency (fire) at the temperature of: 400°C for 120 minutes (F400).

This line consists of 8 sizes with impeller from 450 up to 1000 mm.

This line is characterized by the wide round shaped nozzles in both inlet and outlet, warranty of reduced noise level and high efficiency. Besides these fans allow the effective operation either in exhaust or supply duty. This line is characterized by the use of special components (motor, impeller, casing), different from standard production, suitable to guarantee the essential heavy duty for which they are designed.
