Push pull system

The push-pull ventilation system works by having ducts placed across from each other about four to six meters high. These ducts are used for both pushing the clean air and pulling the dirty air. They are connected to a central filter unit. Bomaksan has developed two distinct methods for extracting air from halls – mixed ventilation and upstream layered ventilation. In both scenarios, a central extraction unit is utilized, such as the Bomaksan ECOG or LINE setup. This unit can be installed indoors or outdoors and is connected through extraction and intake air pipelines. The push-pull mixing ventilation is prefferable when the hall height is lower than 7,5 mt and/or the welding wire consumption is lower than 10 tons per year. If the hall height is higher than 7,5 mt and/or welding wire consumption is higher than 10 tons per year, upstream layered ventilation should be applied. In both systems, Bomaksan engineers, project designers and solution partners ready to implement highly energy-efficient tailor made design. With high quality Bomaksan filter units, minimise the pollutant loads for employees and comply with the local exposure regulations. Bomaksan’s modular units also allows for future expansion without re-investing on total filtration systems. In the context of layered- or displacement ventilation, fresh air is introduced into the designated area through vents located near the floor. This helps facilitate the upward movement of welding fumes by assisting in the thermal updraft.
