RenewAire Adds Model S to EV Series Premium ERV Product Line

Share With:

RenewAire®, a leading manufacturer of HVAC and indoor air quality (IAQ) products, introduces the EV Series Premium–Model S, a static plate enthalpy core-based energy recovery ventilator (ERV) for smaller, entry-level, IAQ-oriented applications in North America.

Like the larger EV Series Premium M and L models introduced in 2020, the Model S offers one of the HVAC industry’s best CFM/watt, exhaust air transfer ratio (EATR) and static pressure capabilities with best-in-class, customizable operational features, but at an economical price point.

The Model S is Home Ventilation Institute (HVI)-certified (CSA 439-09) and designed for pinpoint (IAQ) in new 3-bdrm/2-bath single-family homes under 2,500 square feet, condos, dormitories, manufactured homes and light commercial buildings. Contractors can eliminate the upfront capital, installation and maintenance costs of conventional bathroom fans with one Model S in compliance with the International Residential Code (IRC), but also add energy-saving heat recovery and a sensor-activated Boost Mode to offset IAQ challenges, such as bathroom showering, kitchen cooking or house guests with potential infections. Using a Model S to supplant bath fans reduces home penetrations from four to two, improves the Home Energy Rating System (HERS), and provides local and federal rebate incentives for contractors. 

The Model S’ HVI-rated 1.82-CFM/watt (tested under IECC 2021 standards for motors up to ½-hp) efficiency surpasses the competition. Its many features include variable fan speeds supplying 30 to 130-CFM by an EC motor. The space saving impellor fan helps reduce its footprint to 22-1/2 (l) x 9 (w) x 23-3/4 (h)-inches (571 x 228 x 603-mm) for fitting tight spaces.

The Model S also future-proofs new homes with its 1-inch w.g. external static pressure capacity, which far surpasses the upcoming 0.4-inch w.g. ASHRAE 62.2 Standard revision. Fan speeds automatically adjust to room activity contaminants that are monitored and activated automatically to Boost Mode by CO2, VOC, IAQ or occupancy sensors, or manually with a remote push-button in the space.

The EV Series Premium Model S’s other features are:

The Model S joins the M (Medium) and L (Large) EV Series Premium models, which accommodate spaces of up to 4,000-square-feet and five bedrooms with a minimum 165-CFM of outdoor air, have operating ranges of 30 to 225-CFM and 30 to 280-CFM, respectively.
