Longopac Mini Mega-Strong 4 x 20 meters

- Continuous 20-Meter Bag Cassette System – Each cassette holds 20 meters of continuous tubular liner that produces approximately 20-30 individual bags — eliminating the constant stopping and bag-changing of traditional dust collector bags during concrete grinding, polishing, and floor prep work.

- Mega-Strong 3-Layer Polyethylene Construction – Built from 3-layer coextruded polyethylene with an impressive 1,100-gram dart drop strength rating, withstanding heavy concrete dust, sharp debris, and aggressive jobsite loads without tearing or splitting.

- Hygienic, Dust-Free Bag Changes – Bags are sealed and replaced from the outside with zero contact with the contained waste — operator never touches concrete dust, silica, or hazardous particulates during disposal, dramatically improving jobsite safety and OSHA compliance.

- Universal Dust Collector Compatibility – Compatible with virtually any commercial dust collector or industrial vacuum equipped with the standard 360mm diameter Longopac® system — including Husqvarna, Pullman Ermator, Nilfisk, Klindex, Pulsebac, and other major brands.

- 2-Year Guaranteed Strength – Pack of 4 Cassettes – Strength guaranteed for up to 2 years from manufacture. Sold as a 4-pack of 20m cassettes (80 total meters / ~80-120 bags) — a long-lasting supply for ongoing concrete grinding, polishing, and dust extraction operations. REACH-compliant and SVHC-free.
