Ducting Configurations
The interior ducting system’s purpose is to remove stale air and circulate fresh air to all
habitable rooms. It is the responsibility of the installer to ensure all ductwork is sized and
installed as designed to ensure the system will perform as intended.
The amount of air (CFM) that an HRV/ERV will deliver is directly related to the total external
static pressure (ESP) of the system. Static pressure is a measure of resistance imposed on the
blower by a length of ductwork plus the number of fittings used in the ductwork.
The following pages outline 4 duct configurations, from most desirable to least desirable.
Note: These configurations are intended for typical single-family and multi-family residences.
Applications such as greenhouses, atriums, swimming pools, saunas, etc., have unique
ventilation requirements that should be addressed with an isolated ventilation system.
