Displacement air pollution control for moderate to heavy welding fumes The displacement ventilation piping system is connected to a central extraction and filter system. It is suitable for workshops with medium to high levels of smoke and dust where a spot extractor system is not feasible, or it is used to supplement spot extractor systems. At the workplaces, the system ensures a constant, low velocity, circulating air stream.

• Optimized, low velocity air flow by using thermal air currents
• Uninterrupted continuous operation due to automatic differential pressure-controlled filter cleaning
• Can be adapted to specific work areas due to a flexible number of outlet pipes
• Little noise emission due to a low noise level
• Heating costs minimized by air recirculation
• Convenient operation due to intelligent control via touch screen with diagnostic system
• Contamination free dust collection due to compressed air lift for duct collection container
• Automatic filter cleaning, pressure-controlled
• Control via touch screen
• KemTex® ePTFE filter cartridges
• Dust collection container with pneumatic lifting device
• Can be connected to various extraction systems
• Can be combined with other intake systems to one extraction system
• Adaptable in line with contamination level (outlets)
• Low velocity air flow
• Economical
• Low noise level

Mode of Operation:
• Outlet pipes are installed close to the floor, inlet pipes at a height of 4-6 m and connected to a central extraction and filter system
• Contaminated, warm air rises, is collected through the inlet pipes and cleaned in the filter unit
• The purified, clean air exits from the outlet pipes at low velocity near the floor
• The warm, fresh air displaces the welding fumes towards the inlet pipes and at the workplaces a constant, circulating air stream is created

• Medium to high levels of smoke and dust
• Workshops where local exhaust ventilation is not possible
• To complement local exhaust ventilation systems
• Environments with changing sources of smoke and dust
• For large work pieces or where work positions are well separated
