The Envirco® roomside replaceable (RSR) ducted ceiling module is a lightweight, low-profile terminal air filter. Its RSR gel seal HEPA or ULPA filter provides unidirectional air flow for the most demanding environments, and is ideal for pharmacies and laboratories.
     Servicing the RSR-ducted ceiling module is simple. Users can replace or change the HEPA filters without removing the entire filter from the drywall or tee-bar ceiling grid. The module is available in 24- x 48-inches and 24- x 24-inches with a 10- or 12-inch inlet collar.
