Ideal for job shops, welding schools, and maintenance departments, the Prism Wall Mount unit ensures a cleaner, safer work environment without the need for complex ductwork installations.

This One-Pak® system simplifies the selection process by providing a pre-assembled package that’s easy to install and operate. The low vacuum system is perfect for facilities requiring effective welding fume filtration in confined spaces, helping to maintain air quality and worker safety.
