Centrifugal switch FW 100/2 Dungs

• These accessories FW 100/2 are designed to protect against the lack of air supply to forced-air burners and other blower motors.
• The centrifugal switch FW 100/2 has a hub fastening similar to EN 225-1. This hub is matched to the standard dimensions of oil pump holders and thus ensures a problem-free installation.
• The spindle runs in double ball bearings and is "D" shared for easy connection to drive mechanism.
• The FW 100/2 has already been set at the factory to monitor gas burner blower motors.
• It functions safely both in clockwise and anticlockwise directions.
• Due to centrifugal force, the centrifugal masses move to the outside as speed increases and activate a switching element using the reversing lever.
• Switch-on speed (as speed increases) n ≤ 2565 rpm^-1
• Switch-off speed (as speed decreases) n ≥ 2160 rpm^-1
• Special speeds on request, possible range: 800 - 4000 rpm^-1
• Do not open the centrifugal switch. It is only permitted to exchange the whole unit.
