The HE 5709 is a master controller for 1 to 4 solenoid valves. It optimises filter cleaning in dust extraction systems and cuts compressed air consumption: the pause times are self-optimising and adapt automatically to the current operating conditions.

• Differential pressure-dependent, time-controlled or sequential cleaning

• Automatic teach-in of the connected valves, monitoring for overcurrent and cable break

• Menu-less, language-independent operation, parameterisation via EasyTool Controls 4.0

• ATEX Zone 22, IP65 – longer filter element service life, lower operating costs
