thyristor speed controller BS 1.8
Used in ventilation systems to switch on/off and regulate the speed of single-phase electric motors in voltage-controlled fans.
BVKxk EC
BVKxk EC series fans are used in exhaust air installations of various types of rooms. They are particularly recommended for single-pipe residential exhaust systems. The fans are adapted to be mounted on roof damping bases. The diameter or cross-section of the ventilation ducts depends on the fan’s size.
The BVKxk EC series fans use modern motors with brushless electronic commutation that are subject to stepless speed control.
The use of this type of motor reduces electricity consumption, noise and vibration levels, as well as lets achieving higher speeds and a longer service life.
Centrifugal roof fans with a capacity of up to 5800 m3/h, in a steel casing with vertical air discharge.
