GRAVITY is a triangle brush in antistatic oil-proof NBR compound for scrubbing and vacuuming on machinery, production equipment and laboratory surfaces in ATEX-classified zones. The triangular disk of 160×160×160 mm is particularly suited for cleaning in corners and along machine edges, where conventional round brushes cannot reach. Brass-strand bristles (PXBR/NATBR) provide electrical conduction and prevent static charge build-up.

PX = polyester · NAT = natural hair · PXBR = polyester + brass · NATBR = natural + brass. The bristle disk is detachable and replaceable (spare part: TRI160PO antistatic).

Application areas

GRAVITY ATEX is particularly suited for cleaning in corners, along machine edges and on triangular surfaces in ATEX-classified zones. The triangular form reaches where round brushes cannot.

  • Food production – grain, starch, sugar, light metals
  • Woodworking – sawdust and wood shavings
  • Metal processing – swarf, glass and ceramic fragments
  • Chemical industry – explosive powder and granulate
  • Corners and edges on machinery and production benches
Important notice: GRAVITY ATEX is not ATEX-certified as a product. The brush is manufactured with antistatic materials (NBR body + PXBR/NATBR bristles with brass strands) providing electrical conduction and preventing static charge build-up. It is the installer's and user's responsibility to verify suitability for the specific ATEX-classified environment and zone.

Frequently asked questions

The triangular disk of 160×160×160 mm gives GRAVITY access to corners and edges where round brushes cannot reach. The tip of the triangle can be pushed into right angles and along slanted edges on machinery and production benches.
PXBR is polyester fibres with brass strands — the most durable, suited for harder materials. NATBR is natural hair with brass — softer and does not damage sensitive surfaces. Both types have brass strands providing antistatic conductivity in ATEX zones.
No, the brush is not ATEX-certified as a product. It is manufactured with antistatic materials (NBR body + PXBR/NATBR bristles with brass) suitable as accessories for ATEX-certified systems. It is always the user's and installer's responsibility to verify suitability.
