Industrial Vacuum Cleaners: Threephase 3997

For very heavy duty and continuous service

The 3997 was designed for very heavy duty and continuous service. This threephase vacuum can be connected to the centralized general cleaning or pneumatic conveying systems used in various sectors such as the agricultural-food production or metal-working industries. Many optionals facilitate work where the vacuumed materials are particularly heavy or in large quantities. The electric filter shaker is standard supply. The main features of this vacuum cleaner are:

• Heavy duty vacuum cleaner for continuous use.
• Continuous running due to its 3 phase induction motor.
• Reduced maintenance due to direct coupling of motor and fan without using belts or gears.
• Greater filter efficiency thanks to the large surface area of the filter. This ensures high suction throughout the cleaning cycle.
• Highly effective systems for maintaining filter efficiency with and electrical filter shaker in the 3997W and electro-pneumatic filter cartridge cleaning device in the 3997WC model.
• High suction levels.
• Filter monitoring by means of the Manometer which shows condition of filter at all times. The differential manometer also switches off the machine if the filter becomes ineffective.
• Easily removable container operated by unique drop bin system.
• Control panel with switches for start/stop, hour counter, manometer and motor direction indicator.
• Integral electrical panel with star/delta starting device and electrical controls.
• Large wheels, fixed front wheels and pivoting rear wheels with brakes.
• Lifting brackets for practical movement of the vacuum by forklift if required.
