The Brookvent BTP EC Duct series fans are the perfect solution when ventilation systems require relatively high compression, a strong air stream, and low noise levels. This makes them perfect for utilisation in ventilation installations in residential buildings, collective housing, and public utility buildings in particular. Their compact dimensions make them perfect for limited spaces – they’re dedicated for ventilation ducts of 125mm, 150/160mm, 200mm, and 250mm respectively.
BTP EC fans have compact dimensions, which makes them perfect for
installations in limited spaces.
The fan housing is made of aluminium or steel and the rotor blades are made of high-quality plastic.
The fans use very efficient DC motors with EC technology with an external rotor and backward curved blades. This saves energy, achieves high efficiency and provides optimum control over the entire speed range.
The fan is switched on and its efficiency is controlled by an external 0-10 V control signal. When changing the value of the EC control parameter, the motor changes the speed to match the system requirements.
Available models of the BTP EC series: 125, 150/160, 200 and 250
Duct fans with EC motor with mixed flow rate and efficiency up to 1808 m3/h.
The roof fan is designed for external installation, at the ends of ventilation ducting, in garages, residential, commercial and industrial buildings with a low level of particulate air pollution.
BVK roof fans are used in exhaust systems in various types of rooms. They are adapted for mounting on insulated and damped roof bases.
The diameter or cross-section of ventilation ducting depends on the size and the type of fan.
A roof fan designed for outdoor installation at the ends of ventilation ducting in residential, commercial and industrial buildings, where the degree of air pollution with solid particles is low. The fan can work with the CSR-B controller, which will ensure stable ventilation in all conditions and exactly according to the design guidelines.
