Aerator gear unit
The gear unit is supplied as a two­ or three­stage helical gear unit or as a three­stage bevel­helical gear unit. It is designed for installation in a vertical position.
The output shaft rotates in an oil­dam pipe. This prevents gear oil from escaping at the shaft end. In the case of types H2BV and H3BV, the oil supply is made possible by a flanged­on oil pump. In the case of type B3BV, the oil supply is assured by a flanged­on pump or by a motor­driven pump.
