The DLS DXP 60″ Composite Fan with its variable speed DC drive is the most efficient tunnel/cross-ventilated fan on the market. The fan is made with a durable military-grade polymer material that is UV and chemical resistant. A Mazak fibre-optic laser is used to precisely fabricate the fan’s aerodynamic and structural components. There is also a belt driven version available for this fan.
All the components are made in the USA, and DLS offers a 5-year bearing and shaft warranty.
