Johnson Controls Parallel Fan Powered VAV terminals provide flexibility in performance ranges to meet a multitude of system design requirements.
Terminal units reduce energy costs and minimize carbon footprint. Daikin’s single duct VAV boxes, from 80 to 8000 CFM, provide high performance and set the standard in the industry for construction, performance, and quality. Our fan-powered terminal units, available as parallel and series, prov...

Also called a parallel fan-powered terminal unit, it provides additional air circulation when there is less demand for conditioned air. A modified version called a series fan-powered terminal unit keeps the fan running all the time, regardless of whether the system is in heating or cooling mode...

Reducing the reheat requirement in parallel fan-powered terminal units can be done by increasing the air recirculating at the zone level rather than at the system level. This will allow keeping the system level SAT as cold as possible to reduce fan airflow for the zones in cooling with no ...
