Inflatable Clamps for Big Bags – Filcoflex 

Air-inflated sealing systems for Big Bag discharge stations in bulk solids handling installations.

Filcoflex inflatable clamps for Big Bags are designed to ensure a secure seal between the bag outlet and the discharge system, using a pneumatically operated inflatable sleeve.

When pressurized, the sleeve adapts to the Big Bag outlet, allowing to hold and seal the bag simultaneously, creating a tight seal during discharge and preventing product leakage.

This system is mainly used in Big Bag discharge stations, where it is essential to control dust emissions, improve operator safety and maintain a clean and safe working environment, especially when handling fine powders or potentially hazardous materials.

System operation

The system works in a simple way: position the bag, inflate the sleeve and perform the discharge in a clean, fast and safe manner, without dust emissions.
