Budderfly will leverage Fujitsu’s Airstage variable refrigerant flow (VRF) systems as the core component for its ultra-high-performance (UHP) HVAC architecture.

A common bathroom exhaust ducting mistake is reducing the 6-inch ERV take offs to the 4-inch duct that’s commonly used in bathroom fans. Reducing would cut the potential CFMs approximately 20 percent or more.

ERVs are an important ventilation strategy for eliminating up to 80 percent of the outdoor ventilation air moisture and energy loads for many types of applications. To maximize their benefits, it is equally important to specify serviceable components that can be easily maintained for the life of the system. 

This product ranges from 1.5 to 4.5 tons and 600 to 1,800 cfm. It features a stainless steel or powder-coated cabinet in either a 94- or 104-inch length.

Both models feature a compact 16-inch chassis – ideal for ceilings and small spaces – and a best-in-class hydroscopic resin energy recovery core with no moving parts for maintenance savings and long-lasting comfort.

A primary reason for installing an ERV is to recover energy when there is a fresh air requirement for a building. As fresh air is brought into a building, the conditioned air is exhausted back outside to equalize the building’s air pressure.
