BTP EC series fans are used in ventilation systems that require relatively high compression, strong air stream and low noise. They are an excellent solution for ventilation installations in residential buildings, collective housing and public utility buildings.
Dedicated for ventilation ducts with the following diameters in mm: 125, 150/160, 200 and 250 mm.

CSR-B EC W, CSR-B EC Zero Plus W, CSR-B EC NFC W controller
Controllers of the CSR-B series are constant pressure regulators designed for cooperation with duct and roof fans with EC motors. By continuously controlling the fan speed, they ensure constant pressure in the ventilation ducting. Based on a PI controller, CSR-B controllers have the option to set a constant fan power and programmable upper and lower fan control limits.
