The Vents Micra 150 Ductless HRV - High-Efficiency Single-Room Energy Recovery VentilatorImprove your indoor air quality with the Vents Micra 150 Ductless HRV, a high-performance single-room heat recovery ventilator designed for spaces up to 1,200 sq. ft. This compact, wall-mounted unit is ideal for apartments, bedrooms, offices, new builds and additions, essentially any room where balanced ventilation and an upgrade in indoor air quality is needed - without the hassle and expense of ductwork. At the heart of the Vents Micra 150 is a counter-flow polystyrene plate heat exchanger delivering up to 85-88% sensible heat recovery efficiency, helping reduce heating and cooling loads while maintaining comfortable indoor temperatures year-round. Cold weather note: If the exhaust air temperature measured after the heat recovery core drops below 37.4°F, the unit shuts off the supply fan and runs in exhaust mode until the core warms. Once the supply air temperature rises back above 37.4°F, the unit returns to its normal operating mode. MK-2 Mounting Kit included: Comes complete with the MK-2 mounting kit. (external powder coated metal exterior duct and internal ducting) Key Features: Powerful Efficient: Delivers up to 71 CFM of fresh, filtered air for rooms up 1200 sq ft using low-energy EC motors that consume just 8 to 51 watts, keeping operational costs low. Quiet Operation: Designed for noise-sensitive environments with sound levels ranging from just 1.0 to 1.8 Sones. Built-In Filtration: Includes MERV 7 filter for incoming air and MERV 5 for exhaust, protecting the heat exchange core and improving overall air cleanliness. Cold Climate Ready: Advanced anti-freeze protection system automatically shuts off the supply fan if exhaust air temperatures drop too low, allowing the core to warm up before resuming normal operation. Easy Installation: Ideal for renovations or retrofits: no ductwork required!
