AT501 systems are direct interface between the inside air and the outside air, installed in a sleeve that passes through the wall. AT501 systems work in pairs : units are wired together to ensure the house is not pressurized or depressurized, one blows in while
the other blows out; then after about a minute, they both reverse directions.
STANDARD FEATURES:

Germany COOPER total heat exchange core, upgrade the new dimension of heat and cold precision control, solve the problem of indoor and outdoor temperature difference, so that the indoor temperature is always constant and comfortable state. CFD simulation flow to design, two-way increase air exchange, small wind resistance, high static pressure. Original sheet metal air duct structure design, not only increases the structure of the oad-bearing, but also sound absorption Noise reduction, significantly reduce the crosstalk of fresh air and exhaust air and improve the purification effect.
