Fans made of the following materials:
• Galvanized steel ZZ 275 • Stainless steel AISI 304 • Steel with special coating (zinc, aluminum and magnesium)
Large volume fans The raison d´être of the entire range of fans EX is their long endurance, low maintenance cost and better relationship between the air flow delivered and the electric consumption.

WITH CONE
• Locking shutter with a specific design in order to prevent the air / light from getting inside. • Shutter opening with a reinforced centrifugal system. • Central pulley and propeller support with an airtight, first quality and and permanent lubrication. • Motor with an IP 55 protection and coil insulation degree type F, IE2, IE3, IE4 power classification. • Fan venturi made of plastic material with UV protection. • Front grid according to the standards on safety.
Greater power, highly reliable and maximum effectiveness. Specific EXAFAN design. 15% increase in the performance of the fan, considerably reducing the electrical consumption of the motor. They offer more air flow with a simple assembly and installation system.
WITH PVC CONE
COLOSO 60. A fan for a lifetime, with excellent materials, high durability and corrosion-resistant. • Plastic cone (PP+fibreglass) can be disassembled into 8 parts, self-clipping and stackable. • Plastic shell, adaptable to the panel or wall of the building and divisible into 4 parts for easy transport. • System for fastening on the vertical closure panel of the building. Thus, the shell has a double vertical frame that will be parallel to the interior wall of the building that is supported on the cut upon the wall, and parallel to it. • Chamfered on the shell to embed the sheets and transmit the forces of the fan to the structure of the building. • Steel structure for the transmission of forces to the structure. • Option of installation of valve which can be disassembled into two parts, manufactured in plastic. • Very energy-efficient. 5
