The indoor self circulating smoke and dust purification integrated machine sends purified air into the work area and forms a thin layer of air on the ground. The air layer is formed by the diffusion of cooler fresh air. Indoor heat sources (personnel and equipment) generate upward convective airflow. Fresh air, due to the buoyancy of the heat source, flows towards the upper part of the room and becomes the dominant airflow for indoor air movement. The exhaust outlet is set at the top of the equipment and draws polluted air into the interior of the equipment. The indoor self circulating integrated air supply speed is about<0.5m/s. The movement of the air supply is so low that it has no actual impact on the dominant indoor airflow.

Host Introduction:
The method of treating welding fumes by indoor self circulating integrated machines is through rate filtration. The purified air is sent out from the middle of the equipment and forms a traditional dust supply air flow organization with the suction port on the top of the equipment, which is particularly suitable for the treatment of welding fumes in large workstations. The advantage is that there are no pipelines, and the host location can be flexibly selected and arranged according to the site. As this equipment is purified by indoor air before being discharged into the room, it can greatly reduce the cost of heating and cooling in summer and winter,

Equipment features:
Equipment installation without pipelines, vertical installation, flexible layout, small footprint, able to meet different process requirements of users;
Adopting a reasonable and effective airflow organization of upward suction and downward delivery to capture smoke and dust;
Using high-quality filtering materials, the filtered air meets emission standards; The system adopts indoor circulation to reduce energy loss caused by direct external discharge
