Outlet Connection System AAS

Discover the optimized solution for low-dust discharging – the perfect synergy of efficiency and innovation: Our Outlet-Connection-System (AAS) and the advanced version AAS-EF with integrated dust filter.

HECHT's proven AAS sets standards in low-dust discharge of Big Bags with or without liners. With double protection against dust emission, it ensures the highest level of protection for space and operators, especially with less hazardous and dusty bulk materials in the food, pharmaceutical, and chemical sectors. With an impressive performance of up to OEL 1,000 - 5,000 μg/m³, the OCS is the ideal choice for demanding applications.

Our innovative advancement, the Outlet Connection System with integrated dust filter (AAS-EF), defines efficiency and convenience at a new level.
The integrated dust filter eliminates the need for an external filter unit. With a performance of up to OEL 100-1,000 μg/m³, the AAS-EF is the preferred choice in the chemical, food, and pharmaceutical industries.
