Using the same aluminum main body, you will have an adapter that will allow you to use a threaded canister. Now you can empty the container by just unscrewing it rather than the four screws from before.
The filtering section has a container thay houses stainless steel mesh to help filter out the contaminated air. There are also extra baffles in the design as well.
The new parts are made of Carbon Fiber/nylon for durability and substantial weight savings.
