Provide and install make up air ductwork from roof opening to new HVAC unit Provide and install supply air duct work from discharge of new HVAC unit to new HEPA filter diffusers. Provide and install return air duct work from top of return air chases to inlet of new HVAC unit. Ductwork to be externally insulated. Cut nominal 2 x 4 openings in existing dry wall ceiling to accommodate SS filter frames Provide and Install SS HEPA filter frames into ceiling cut outs Provide and install HEPA filter assembles, aluminum housing 50 mm deep HEPA filters (99.99% efficient on 0.3 micron particles) HEPA housing to have 10 inch duct connections with integral balancing dampers. HEPA filters to have room side injection test ports Provide and install two (2) wall mounted return air chases that penetrate the existing ceiling and have duct connections on the top. Chases to be welded carbon steel powder painted white that mount externally to existing walls next to the gown room/ main room entrance door; return chases to have SS inlet dampers (manually adjusted for balancing), factory installed in each chase; bottom of damper to be 4 inches +/- above finished floor. Provide and install in Cleanroom side wall (location to be determined) on personnel speak thru device for communication between personnel in the Cleanroom and those outside. Remove existing wooded entry doors into the gown room and Cleanroom; replace with welded painted steel doors each with flush viewing window, passage hardware and drop down floor seal.
