Nilfisk S3 M Class Industrial Vacuum

The Nilfisk S3 M Class Industrial Vacuum is a high-performance triple-motor vacuum designed for demanding industrial environments where safe and efficient collection of M Class hazardous dusts is essential. Equipped with 3 x 1000 W motors, the S3 delivers exceptional suction strength with a high airflow of 135 L/sec, making it ideal for manufacturing, woodworking, construction, surface preparation, and general industrial cleaning applications.

This model features a large M Class polyester star filter, offering excellent filtration efficiency for fine and harmful dusts such as wood dust, silica dust, composite materials, and other medium-risk particulates. The integrated manual filter shaker allows operators to maintain consistent airflow and suction performance, reducing downtime and extending filter life during continuous operation.

To maximise operator safety, the S3 M Class includes the Longopac continuous bagging system, which enables dust to be collected in a sealed, continuous plastic sleeve. This eliminates secondary dust exposure during disposal, ensuring compliance with site safety regulations and providing a cleaner, safer working environment.

The vacuum features a large 70mm inlet, allowing for a wide range of heavy-duty tool configurations. Adapters allow users to work with 70mm, 50mm, or 40mm hoses and accessories, making the S3 M Class extremely versatile for different applications and material types.
