APPLICATION

• ТТ PRO EC fans combine the versatility and outstanding performance of both axial and centrifugal fans producing a powerful air flow and high pressure while retaining the signature energy-efficiency and response of EC motors. 
• Integration of several fans into a single computercontrolled system with sensor feedback combined with speed control across the entire dynamic range.
• Designed for supply and exhaust ventilation systems requiring high energy efficiency, excellent response, high pressure and air flow rate while keeping noise under control – such as highhumidity commercial and industrial spaces (e.g. bathrooms and kitchens) as well as flats, villas, shops and cafes. 
• Compatible with air ducts from 100 to 315 mm in diameter.

DESIGN

• The casing of ТТ PRO EC fan is made of low-combustible polypropylene.
• The removable central unit with a motor, impeller and terminal box is attached to the fittings by means of special mounting brackets with integral latches. This helps to make the fan maintenance extremely simple and convenient. Fan service no longer requires major disassembly and dismantling of the fan: all you have to do is remove the main unit from the casing and carry out the maintenance as required.
• The inlet fitting has a profiled header which ensures smooth air flow into the fan.
• Conically shaped impelles with specially profiled blades cause circular velosity rise, that resuts in airflow boost and pressure increase comparing to conventional design. 
• The fan outlet combination of a diffuser, specially designed impeller and rectifier allow for the optimim air distribution: high air capacity and pressure without excessive noise.

MOTOR

• The fans feature high-efficiency electronically commutated (EC) direct current motors.
• These state-of-the-art units offer excellent energy efficiency.
• In addition to that EC motors combine high performance and optimum response over the entire speed range. The performance efficiency of electronically commutated motors reaches a staggering 90%.
