Key features

Dust bag application

Dust bags for Master professional blowers are used to clean the air. In the air filtration process, the dust bag separates the solid particles, e.g. dust from the stream of flowing air and stops them on the surface.

Example: underground works – fresh air is blown in, used air is blown out and filtered.

Dust bag application underground

Master dust bags have been designed to remove fine dust particles. They can be used during light and medium construction and renovation works, such as:

  • Cutting wall
  • Polishing walls and floors
  • Polishing terracotta or glaze

And also in:

  • Workshops
  • Production halls with dust pollution
  • Warehouses

Master dust bags are made from a special polyester material for air filters.

The dust bag filtration level EPA 10 (Efficiency Particulate Air Filter) guarantees a high level of efficiency and air filtration.

Length of dust bags – 3.5m
