Roof Fan BLAST
The BLAST roof fan is an efficient ventilation solution for large production halls, warehouses, workshops and other industrial facilities. Its galvanized, powder-coated steel housing provides increased resistance to external conditions.
About the product
BLAST is a roof exhaust fan designed for effective air exchange in large production halls, warehouses, workshops and other industrial facilities. The series comprises three models with airflow capacities of 2,300, 3,700 and 4,400 m³/h, allowing the unit to be matched to the specific needs of the facility.
The powder-coated galvanised steel housing, together with the canopy and outer panels protecting the motor from precipitation and the drainage slots, provides high resistance to outdoor conditions. The IP54 protection rating ensures resistance to dust and water splashes.
The AC induction motor allows speed control via HC voltage regulators, TRO thyristor controllers or the programmable HMI SINGLE BMS controller. The unit is installed on a dedicated roof base with M6 bolt holes — the load-bearing capacity should be taken into account during installation, as the weight of the unit with base may exceed 60 kg.
