Air leakage:

• Leakage does not exceed 3 cfm/ft.² against 1” w.g. differential static pressure.

• Connections between decks are hard alloy aluminum rods, stamped into one deck and U-bolted to the opposite deck.
• Connections between decks will not develop any wear or play.
• No internal mechanism to loosen, fail, or omit.
• Transmission of torque, or stroke is direct and without losses.
• Blades are cored to appropriate angles to ensure 90º operation between decks for two-deck multizone.
• Internal zone dividers are designed to accept duct connections.
