The J series impeller is an economical but effective mixed flow impeller which meets the application needs of such units as room air conditioners, humidifiers, dehumidifiers, and kitchen ventilators. The performance data shown in the PDF document for the J series were obtained with the impeller applied in a cylindrical orifice of the proportions shown in the specification chart PDF and are an approximate measure of the performance to be expected in a similar application.
The J fan is made in a 50° pitch. The fan is of one piece construction with the blade structure being made out of aluminum to which a zinc plated steel hub is spun.
