Good airfl ow is critical for the performance of the entire system. It is highly
dependent on the quality of the ducting installation.
The ducting should be running as stright, smooth and taut as possible
minimizing the number of 90° bends (two 90° bends can reduce the airfl ow
by 25°).
If transition box is used, the total area of supply air ducts going out of the
box should at least equals the area of the supply duct going into the box.
ALL DUCTING SHOULD:
- Be appropriately sized for each application.
- Run as smoothly and taut as possible.
- Have as few bends or loops as possible.
- Be securely fastened to prevent sagging during boat operation.
- Have all excess ducting lengths trimmed off.
- Not be fl attened or kinked.
- Be Insulated when located in high heat load areas (hull side, mechanical
compartments, etc.).
- Be properly protected against potential damage when routed through
open areas.
- Do NOT route ducting through engine room or any area where it may be
exposed to dangerous vapors or exhaust fumes.
