Panasonic’s Intelli-Balance 200 Energy Recovery Ventilator (ERV) provides a stand-alone (doesn’t require connection to central HVAC) balanced ventilation option with a standard MERV 13 filter. The unit, which can be floor, wall, or ceiling mounted, features a multi-speed selector that allows airflow adjustments from 60 to 200 cfm, as well as a boost function that allows occupants to increase ventilation on demand. This unit also features two electronically commutated brushless motors whose speed adjusts based on static pressure. panasonic.com
