The most powerful. The biggest!
Nilfisk #3997 - will handle two (2) 35" concrete grinders. -- 46% Greater Filter Surface Area than its predecessor (model T48) for unparallel productivity
-- Complete with Automatic Filter Cleaning

The most powerful, mobile, industrial vacuum in the Nilfisk range, complete with three-phase suction. With oversize filter surface areas and automatic filter cleaning provides unparallel productivity and efficiency in a completely self-sufficient industrial vacuum.

The filter can be monitored in real time via the vacuum-gauge that shows the remaining filter capacity; moreover, a differential switch will turn off the vacuum should the filter become completely caked.

The included Longopac® Collection System makes the disposal of the collected material a very fast and easy operation while the large front wheels and the rear pivoting ones with brakes provide easy maneuverability.

Heavy-Duty Applications: Sand and heavy material, cement trenching, volumes of ultra fine powder, etc.

Only Nilfisk is backed by more than a century of vacuum and filtration expertise.

Using a combination of customer understanding and technical know . . . to provide the features and functions to meet your application needs.
