Vacuum units
Operating vacuum required can be produced in many ways.
Witte vacuum units feature the following:
• Oil lubricated vacuum pumps with an end
vacuum rate of 20mbar absolute at full suction
capability of i.e. 10m3 upto 250m3 per hour
• Integrated pressure difference switch, which
automatically switches the vacuum pump on
or off thereby ensuring vacuum during machi-
ning but avoiding unnecessary idle running
• Protection switch which protects electric
motor from overheating
• Air filter which protects pump from dirt
(made of acrylic glass with exchangeable
air filter cartridge)
• Careful assembly of compatible components
guarantee trouble-free and almost
maintenance-free operation of Witte
vacuum units in many applications
