Gas-Tight Belt Conveyors
Sealed design for high-dust or eco-sensitive environments, 0°-90° tilt, zero dust leakage.

Product Overview
The Gas-Tight Belt Conveyor is a specialized material handling system engineered for high-dust environments or applications requiring stringent environmental protection. Featuring a fully enclosed structure and advanced sealing technology, this conveyor ensures zero dust leakage, making it ideal for industries such as chemical processing, food production, pharmaceuticals, and mining. Its vertical design supports a maximum incline angle of 90°, enabling efficient vertical material transfer while maintaining airtight integrity.
Key Features
