NG40 series is specifically developed for condensing boilers with premix burners. Fitted with brushless DC motor, the design of the blower allows to be used in appliances with zero governor and positive pressure air-gas systems. The blower delivers high pressure (up to 3,000 Pa) and can guarantee wide modulation range up to 10:1. NG40 uses SIT developed electronics equipped with a programmable microcontroller managing several functional curves therefore NG40 can be easily fitted to a wide range of applications.

Three principal models are available:
– Controlled by 230 V AC electronic board
– Controlled by 24 V DC electronic board
– Without electronic board, with hall sensor only.
