AirScrape Non-Contact Conveyor Skirting & Dust Suppressor (Venturi Patent)
Exclusive Importer & Engineering Partner in Israel: S.F.I. Engineering & Conveying Ltd.
A revolutionary, patented conveyor skirting system designed to eliminate belt friction, wear, and dust emissions. Constructed with a unique inward-facing steel frame and diagonal blades, it deflects large material particles back onto the belt while utilizing the conveyor's natural airflow to generate a negative pressure vacuum (Venturi effect). This vacuum pulls airborne dust and small particles back into the main material stream without making physical contact with the conveyor belt.
Core Engineering & Operational Benefits:
· Zero physical contact with the conveyor belt eliminates skirt-induced belt wear, extending belt lifespan significantly.
· Drastically reduces dust emissions, minimizing material loss and improving workplace safety and environmental compliance.
· Lowers conveyor motor energy requirements by eliminating high friction caused by traditional rubber skirting.
· Maintenance-free design reduces operational costs, offering simple installation and a continuous gapless seal.
· Available in certified fire-resistant and anti-static materials for hazardous, explosive environments.
Expanded End-Use Industrial Applications:
Application 1: Concrete & Cement Raw Material Handling
Transfer points in cement plants are notorious for high-velocity dust generation and material spillage, which damages the conveyor and creates hazardous working conditions. Traditional rubber skirting rubs against the belt, wearing out in weeks and carving deep grooves in the expensive belt. Implementing the S.F.I. AirScrape provides a complete seal without touching the belt, utilizing the air current to draw fine cement dust back into the flow, saving thousands in belt replacements and cleanup costs.
Application 2: Coal-Fired Power Plant Conveying Systems
Coal conveying produces highly explosive, hazardous fine coal dust at transfer chutes. Traditional skirting is prone to generating frictional heat, a major ignition hazard. The non-contact AirScrape completely eliminates friction-related heat while utilizing fire-resistant, anti-static materials. Its Venturi-suction action keeps coal dust securely inside the material stream, greatly reducing explosion risks and satisfying strict safety standards.
Application 3: Glass Manufacturing Silica Sand Conveyors
Silica sand is extremely abrasive. When trapped under traditional contact skirting, it acts like sandpaper, rapidly grinding down both the skirting and the conveyor belt. AirScrape's inward-facing diagonal blades deflect sand grains away from the edges without any contact. It prevents any silica sand from spilling, protecting the conveyor system and minimizing inhalation risks of crystalline silica dust for operators.
