Pressure Relief Dampers will be provided in each OT to prevent cross contamination of air from clean and dirty areas. Suitably sized air pressure relief damper will be strategically placed, enabling differential room pressure to be maintained and ensure that when doors are opened between clean and dirty area. Counter-weight balancing system will be provided in the PRD to maintain positive pressure inside the operation room. Air pressure stabilizers will have unique capability of controlling differential pressure to close tolerance. The PRD will remain closed at pressure below the set pressure and should open fully at pressure only fractionally above the threshold pressure. The body will be epoxy powder coated as per standard BS colors. First class electrolyzed steel plate will be used for body and with high grade SS304 Stainless Steel for blades.
