PIR detection, the PIR sensor will detect when the operating area has been clear of personnel for more than 15 minutes and automatically switch to LNS green-saving mode to reduce the noise level, save energy and prolong the service life of filter.

The hot-bulb airflow velocity sensor performs real-time monitoring of the air velocity of the working area and keeps a constant air velocity in the cabinet by regulating the fan speed with a microcomputer system.

High efficiency AC centrifugal fans combined with an innovative air distribution system to ensure lower noise and more uniform air flow.

The operating area utilizes an airflow disruption design and its front window has air curtain protection at the upper edge and in the surroundings, which can prevent cross over air flow between the inside and outside and thus preventing the diffusion of the internal and external pollutants.
