Specification for SD250 heat recovery fresh air unit
.Super purification
3 stage air purification: coarse filter, electrostatic cleaner, HEPA filters. It can reach 99.99% air purification efficiency
Super energy-saving
Aluminum alloy heat exchanger enables heat exchange between outdoor fresh air and indoor exhaust air, the heat recovery efficiency is as high as 90%, dramatically reducing the AC load.
Monitoring oxygen deficiency
CO2 sensor can monitor the indoor oxygen deficiency in real time, and automatically alert the end users to increase ventilation when oxygen deficiency occurs.
Ventilation
Intake the outdoor fresh air, meanwhile vent the indoor dirty air. The ventilation frequency is 1.5 times per hour, giving you a sense of nature.
Quiet operation
Inverter-controlled fan produces inaudible noise under low speed operation.
Extremely low Cost
Excellent life cycle cost; replacement interval of HEPA filters is three times longer, low maintenance cost.
Simple installation
A plug-and play concept; 100% fresh air or return air can be selected with return air adjusting valve separately.
