When the application calls for cooling capacities or external static pressures that cannot be met with standard or high-performance direct-drive fan coil units and large central station units are a financial challenge, our Belt Drive Air Handlers Horizontal and Vertical are the perfect economical fit for your needs. They are great for straightforward horizontal or vertical applications with a simple design. The best applications for these units are when space requires less than 1.5” of external static pressure on the fan for ductwork and doesn’t require a custom arrangement.
