Explain Bag Expansion Mechanism

What happens here

After placing a fresh plastic bag into the bagger unit, the presenter explains the innovative design that prevents the bag from being sucked up into the cyclone, a common issue with traditional cyclone separators when using plastic bags. He details how a 'labyrinth of air passages' (an internal air distribution system) draws the bag down and causes it to expand until it is 'drum tight' against the bottom of the collection bucket. This ensures the bag remains open and functional throughout the dust collection process.

Goal: The unique 'labyrinth of air passages' mechanism is explained, which causes the plastic bag to expand and stay 'drum tight' during vacuuming, preventing it from collapsing into the cyclone.
