Delfin DHV Hopper

The filtering system comprises polyester felt filter sleeves with internal tensioning springs, and polyester safety cartridge to protect the pump. An automatic time-controlled system cleans the filters via chamber backwash valves, ensuring maximum performance even in continuous and prolonged use of the machine. Compressed air for actuating the valves is supplied by a compressor installed on board the machine.

The lower hopper has a capacity of 1000 liters and can be emptied at the bottom via a manually controlled butterfly valve. Pneumatic actuators and other types of dischargers are available.

Large inspection doors allow easy access to the motor compartment, while eyebolts make it easy to handle the unit by forklift.

A push-button panel means you can easily operate the vacuum cleaner without having to directly access the electric panel.

Raising frame available for Big Bag emptying.

Available in Atex-certified version.
