Dust and debris control products protect equipment, inventories and personnel from unacceptable or dangerous contamination. They are designed to increase visibility, prevent accidents, and reduce the risk of explosion and fire. Dust and debris control products can also be used to reduce equipment wear, prevent or eliminate odors, and ensure compliance with health and safety regulations. There are many different types of dust and debris control products. Examples include area hoods, non-contact web cleaning systems, and ballistic nylon curtains. Area hoods and area hood systems are designed to collect dust-filled air inside and around machinery. Local hoods, booths or enclosures, and side, downdraft and canopy hoods are common types. Non-contact web cleaning systems use an ionized stream of air to remove dust from paper webs before contaminants become airborne. Ballistic nylon curtains are used to contain wood chips, metal filing and other debris from cutting operations. For carbon-based airborne mists, vinyl or plastic curtains can be used.
