Our low-sound, low-cost octagonal fan
is making big noise in the air control industry.

Greenheck has created a new price/performance niche, with a hybrid-design, mixed-flow inline fan for clean air applications where quiet operation is a must. The highly efficient belt-driven EQB beats typical tubular and square centrifugal fans in energy savings, and handles volumes up to 23,000 CFM and up to 3 in. w.g.

The total cost of ownership analysis shown in the graph is based on operating costs for a period of three years where the fans operate continuously at 1725 rpm, 24/7, with an energy rate of $0.10/kWh. Fans were selected for 10,000 cfm at 2 in. wg of static pressure. Maintenance costs were estimated at $65/yr. Note: Example is based on estimated costs. Use and installation variables may produce different results.
