Cut nominal 2 x 4 openings in existing dry wall ceiling to accommodate SS filter frames Provide and Install SS HEP filter frames into ceiling cut outs Provide and install HEP filter assembles, aluminum housing 50 mm deep HEP filters (99.99% efficient on 0.3 micron particles) HEP housing to have 10 inch duct connections with integral balancing dampers. HEP 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. Inspect existing walls, patch any cracks or crevices, and finish paint with dry wall nonshedding epoxy paint, color to be determined. Silicone caulk all floor to wall and wall to ceiling joints.
