Abstract: Wide-range disposal of waste bedding affects negatively on sanitation of barrier facilities. Therefore, it is very essential to develop an automatic litter suction equipment driven by vacuum vortex pump for reducing spread of the micro-organisms in barrier facilities, keeping healthy of laboratory animals, saving labor and consumables costs, as well as maintaining environmental sanitation inside and outside the barrier facilities.
