Reducing duct length means reducing friction surface area, allowing for faster and stronger airflow without increasing fan speed.<\/span><\/p>\n<h3><b>2. Minimize the number of sharp turns.<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">90-degree turns<\/span><span style=\"font-weight: 400;\">0<\/span><span style=\"font-weight: 400;\"> It is the &quot;enemy&quot; of pressure.
