Bellows for Protection and Containment

Bellows and way covers

Bellows protect people and equipment. These flexible material enclosures extend and collapse to keep dirt, debris, and other foreign objects away from machinery. They are essential for medical imaging equipment, machinery used in clean rooms, and anywhere else where cleanliness is paramount.
