Merritt Environmental Products can be a resource for HVAC intake modules that normally house HEPA filters. Pictured here is a Bag-In-Bag-Out HEPA module and this unit is required when the filters are subjected to hazardous dusts. This module configuration allows for dust-free changing of the filter due to the hazardous nature of the dust in the air stream. Please e-mail us with some detail on your project and we will follow up to confirm the module best suited for your application.
