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.
