Designed for demanding abatement, restoration and remediation projects, the OA600 Plus is equally capable in commercial buildings, factories and medical facilities. These units' aircraft-grade aluminum, riveted housings are carefully sealed and stand on hospital-grade non-marking casters to ensure effortless portability. The utmost attention is given to sealing all critical seams with silicone both before and after riveting, ensuring an airtight path that guarantees no contaminated air circumvents the HEPA filter. Additionally, the OA600 Plus machines feature an easy-to-clean aluminum surface that will withstand the abuse of critical environments. Embracing versatility, the OA600 Plus model offers an array of choices for pre-filters, HEPA filters and accompanying accessories. The standard configuration includes a Dustlok pre-filter, primary/secondary filter and an impressively efficient 99.97% HEPA filter. Our Dustlok pre-filters are enhanced with an anti-microbial additive to prevent bacterial growth, while a tackifier boosts its dust-holding capacity to ensure the maximum life of the primary HEPA filter.
