Renewaire has a complete lineup of residential Energy Recovery Ventilator (ERV’s) to fit any home size and budget. The smallest unit is the BR70, which has an airflow range of 40-70 CFM. The BR70 is optimally sized for the small residential home, apartment or condominium ( up to 1500 sq. ft.). The BR70 is designed to mounts directly to furnace (AC) return air ductwork, or to an exterior wall (with TW Kit) with just two duct connections. This units cuts the installation time drastically. Effective ventilation is ensured with integral automatic proportional runtime control.
The next size up from the BR70 unit is the GR90, EV90, EV90P. The airflow range of these models is 40 – 110 CFM. The GR90 is the “economy” model. It has a galvanized cabinet and no power cord. The GR90 is ideal for installations where the unit is not visible and can be hard wired. The EV90 comes with a line cord and has a painted cabinet and we consider this to be the “standard” model. And the “premium” model in this size range is the EV90P, which is similar to the EV90, however it has a larger energy recovery core, making the EV90P a more efficient model. These units are optimally sized for the small residential home, apartment or condominium (up to 2000 sq. ft.).
Going up a size takes us to the EV130 and BR130. The BR130 shares the same design concept as the BR70, which is designed to be mounted to an exterior wall or directly to furnace (AC) return air ductwork with just two duct connections. The EV130 and BR130 have typical Airflow Range of 50-140 CFM and are optimally sized for the average residential home (up to 2700 sq. ft.)
The next size up is the EV200. The EV200 has a typical Airflow Range of 100-200 CFM and is optimally sized for the larger residential home (up to 4000 sq. ft.) The last and largest unit in the Residential lineup is the EV300. The EV300 has a typical Airflow Range of 150-300 CFM and it is optimally sized for the larger residential home (up to 6000 sq. ft.)
Depending on the layout of the home, it can be more effective to install (3) EV130 or EV90’s instead of (1) EV300. This decision needs to be made by the designer and might help in having more uniform “fresh air” within the home. Ideally you want to try to extract the air from areas like the kitchen and bath, this way you will be removing odors. However, be careful not to put the air intake too close to the stove, as you don’t want to get grease inside the unit.
