Ventergy BVS 120 Blending / Filtering Ventilator & Accessory Kit (25 724) - This is a fresh air system - not necessarily an exhaust system. This kit mixes fresh outdoor air with air from two bedrooms - then filters the air and distributes to single supply port in the living space.
The BVS Blending Ventilators are designed to provide fresh outdoor air blended for tempering, with indoor air drawn from bedrooms or areas typically not served by a central thermostat, before filtering and distributing this air to the main living areas of the home. Thermal comfort is enhanced because warmer air is drawn naturally from the heated living areas to the cooler bedrooms.

General: BVS Series blending ventilators are highly versatile continuous duty rated units for residential applications, and meet ENERGY STAR efficiency criteria for low energy consumption. The BVS is designed to provide fresh outdoor air, blended for tempering with indoor air drawn from bedrooms or areas typically not served by a central thermostat, before filtering and distributing this air to the main living areas of the home. Thermal comfort is enhanced because warmer air is drawn naturally from the heated living areas to the cooler bedrooms. The BVS is designed to filter both indoor and incoming fresh air, and prevent the introduction of contaminants as a result of unwanted infiltration through leaks in the building's envelope. By slightly pressurizing the structure, the BVS also reduces risk of back-drafting heating appliances, water heaters, and fireplaces. Quiet continuous-duty energy efficient external rotor motors with permanently sealed bearings provide many years of maintenance-free performance.
Construction: The BVS series fans are constructed of heavy gauge galvanized steel to prevent corrosion caused by moisture. The cabinet is internally lined with UL rated, acoustic closed-cell foam vapor barrier insulation. This allows for installation directly above living space, or in unheated plenum spaces without concern for noise or condensation. Duct connecting collars may be relocated on the fan intake manifold to accommodate differing installation requirements.
Fan Controls: The fan can be operated manually, or automatically by a programmable timer, dehumidistat, or other appropriate electronic switch device. The fan may also be operated in conjunction with a variable speed control.
Accessories: To ensure specifi ed performance, each BVS is supplied with compatible supply and return air grilles, corresponding rough-in boots with back draft dampers, and fresh air intake weather hood. Accessory packages are available to accommodate applications ranging from single bedroom apartments to five bedroom houses.
Locating and Installing the Fan: The compact dimensions and versatile mounting options permit installation above drop ceilings, between ceiling joists, or within a small soffit locations. They can be installed either horizontally or vertically.
