Heat Recovery Ventilator

The S&P HR Series heat recovery ventilators (HRVs) are ideal for use in cold climates where home heating is essential. The HR Series uses one motor to exhaust stale room air and another motor to bring fresh outdoor air back into the house. The technology of a plate heat recovery core is that it transfers warm ambient air from one airstream to the other without mixing the air streams for maximum efficiency and comfort.

Downblast Belt Drive Centrifugal Roof Exhaust Fan

Downblast belt drive fans are designed to exhaust air up to 28,000 CFM, with high static pressure capability up to 1-1/4". The belt drive results in lower operating RPM and sound levels, making the DB well suited to applications where quiet operation is important. Belt drives also permit easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof mounting permits short duct runs and more efficient operation.
