The filter cloth is horizontally covered above the conveyor belt to keep the dust accumulated due to material movement in the material flow inside the conveyor belt. During this process, the air inside the filter cloth is circulated. This specially developed filter cloth is suitable for dust particles and has self-cleaning characteristics, with excellent long-lasting dust retention effect. This type of filter cloth can effectively suppress dust and small material particle leakage, and different quality filter cloth can be equipped according to different environmental conditions, such as anti-static filter cloth. The dust filter cloth installed at a specific distance can improve the effectiveness of the dust prevention system and prevent the formation of dust.

The DustScrape is a combination of dust filter cloth and AirScrape® and is a highly effective system against dust formation. An efficient compact solution for dust-free belt conveyors with comparatively low costs and energy input.

A DustScrape-unit has a system length of 2m and is available for all belt width. That is why belt sections of optional length can be equipped or upgraded with the DustScrape. The selection of the appropriate AirScrape® is dependent on the loading width of the conveyor belt and the required load-free area at the side of the belt. In the load-free are the side sealing works by means of air suction and the accompanying dust retention properties. The filter cloth stretch over the material is permeable to air and excess air can escape.

The AirScrape® side sealing and the filter cloth in combination form the DustScrape system. The AirScrape® does not allow dust or fine material to exit. Additionally, the arrangement of the lamellae has the effect that coarse material is led back to the middle of the belt and thus avoiding material spill completely. The contact-free concept protects the side sealing

The contact-free concept protects the side sealing and the belt and maintenance intervals have become redundant. Because of the filter cloth properties, the material and dust are kept in the plenum and excess air can escape through the pores. Accumulating pressure is thus being released. Active dust removal or enlarging of the closed plenum that is usually connected to costly modifications is redundant.

• Health protection by dust protection
• Easy upgrade of existing plants to improve compliance to the new
environmental standards
• Easy assembly
• Can be optionally extended or shortened
• Maintenance- and contact-free
• Available in different qualities (anti-static)

• Extremely long-lasting dust retention due to self-cleaning properties
• Effective against deflation
• Decreases energy costs
• Almost no electric energy is needed for dust extraction (use of system
overpressure by falling processes at the transfer points)
• Ideally effective with the side sealing AirScrape®
