The equipment Use static breeze technology to distribute the clean air to each single cage, The level of filter is up to 99.99% to provide the best protection of animals. Users can adjust the ventilation number of cages per hour, the air inside the cage will go to the outdoors through high efficiency filter, to protect the health of operators. The gas diffuses slowly, the air flow rate inside the cage is less than 0.13m / s, the air flow rate of animals is usually 0.02 ~ 0.04m / s, the operation noise is less than 49dB. the self-closing tunnel ensure cages integrate and are absolutely sealed: the self-closing water channels ensure provide fresh water to animals in minimizing the number of cases. IVC can ensure the air go through effective filtration before enter each cage while also maintaining the same system, relatively independent of each rearing unit without disturbing each other. The product consists of four components, which are air supply systems, air exhaust systems, racks and cages. Air supply system and exhaust system are used imported fan with long life, and low noise. Exhaust system use high efficiency active carbon, to ensure environmental protection. Rack is made of shaped stainless steel tubes steel 304,and the cage is made of PSU material, it will not deformate under high temperature 121 °Cand 15 pounds pressure within half an hour.
