Doors are 4″ thick with double overlapping air/acoustic seals around the sill, jambs and header. Each door has two hinges and two latches with inside release handles. Hinges are heavy duty ball bearing type designed for door size and weight. Latches are wedge lever type with inside handle. Doors are installed to open against air pressure. Windows are furnished for doors where required, and consist of 1/4″ tempered glass, sealed acoustically and air tight with rubber seals. Windows are mounted in a molded plastic frame to eliminate air leaks.

Base Construction

Bases are constructed from structural steel channel iron, and are engineered to support the components within as well as the entire unit. A 1/4″ steel grip guard plate is used for the flooring surface to eliminate any “oil canning” and create a non slip surface. The base is fully insulated with 2″ urethane insulation. A 1.5″ collar around the entire unit is provided to act as a auxiliary drain pan. Emergency drains are also provided and terminated at side of unit.

Units are designed for air leakage of below 1% of total capacity.
