Air bag fitted between the 2 rows of boxes can be inflated and deflated individually to create an air pocket forcing air to pass through the boxes. There is a vertical airbag at the end of each row that blocks off the air to create a pocket. These bags are fitted onto rails so if the store is only partially full you can move the bag to align with the last row. The air compressor and inlet pipework is fitted to the top of the suction wall to allow easy access and installation.
