More recent loader designs have features like slanted lids for easy access, clear glass center sections, so operation can be viewed, and flat bottoms that do not protrude down into the container on which they are mounted.

Other models tilt from the bottom and top for hands-free access to the filter and for cleaning.

Additionally, they may have modular sections that can be rotated to allow easier hook-up of vacuum and material lines. Some even have a loader control on a pendant that can be used to program multiple loaders.
