This article provides the airflow performance data for Vertex Ducted Central Split (DYC-18) systems.

<h2 id="introduction"><u>Introduction</u></h2><p>This article provides the airflow performance data for <a href="https://www.pioneerminisplit.com/collections/vertex-ducted-central-split" target="_blank" rel="noopener noreferrer">Vertex Ducted Central Split (DYC-18) systems</a>.&#xA0;</p><p>The airflow data is based on the cooling performance of the coil and without a filter.&#xA0;</p><p>Keep the external static pressure within the minimum and maximum limits shown in the table to ensure the normal operation of cooling, heating, and electric heating.&#xA0;</p><p>The highlighted areas in the table indicate the airflow is within the required range of 300-450cfm/ton.</p><p><img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026012218-9df50187-9787-46fa-8827-878cb058d730-dyc18_idu_airflow_performance.png" style="width: 1000px;" class="fr-fic fr-dib fr-bordered"></p><h2 id="notes"><u>Notes</u></h2><ul><li>Use the advanced airflow as the rated airflow for the full-load operation of the machine.&#xA0;</li><li>The rated airflow of a system without an electric heater kit requires 300-450 cubic feet of air per minute (CFM).&#xA0;</li><li>The rated airflow of a system with an electric heater kit requires 350-450 cubic feet of air per minute (CFM).&#xA0;</li><li>The air distribution system has the greatest influence on airflow. Therefore, the contractor must only use the procedures recognized by the industry.&#xA0;</li><li>The design and construction of the air duct must be done carefully. Poor design or process will lead to significant decline in system performance.&#xA0;</li><li>Set the air supply duct along the periphery of the air-conditioned space with the appropriate size. An improper location or insufficient airflow may lead to insufficient ventilation or noise in the ductwork.&#xA0;</li><li>The installer must balance the air distribution system to ensure that all rooms have proper quiet airflow. Use the speedometer or airflow hood to balance and verify the branch duct and system airflow (CFM).&#xA0;</li></ul>
