Map and globe skills read a map answer keyInline centrifugal fan from 6" up to 10" inlet. Mounted on a roof curb or a Inline, JET fans generate a high plume exhaust to ensure maximum dilution of gases in the environment. Smooth and quiet performance. Ideal for water treatment plants and fume hood exhaust applications. Soil vapor extraction (SVE) is a prevalent remediation approach for volatile contaminants in the vadose zone. A diminishing rate of contaminant extraction over time is typically observed due to 1) diminishing contaminant mass, and/or 2) slow rates of removal for contamination in low-permeability zones.

  • MAXTECH ENGINEERS is established as one of the leaders in the Air Pollution Control industry. Our experience covers all facets of Dust, Fume and Industrial Ventilation Control systems for general industrial applications. There are two methods of high vacuum extraction: welding guns with built-in extraction (fume extraction guns), or separate suction nozzles of various designs. Fume extraction guns. Use fume capture nozzles built into the gun tube and handle. The extraction airflow is approximately 35 to 60 CFM (60 – 100 m3/hr) for integrated fume extraction guns.
  • fume hoods shall not be placed in a location that will . adversely affect their performance. Placement with respect to open windows, doorways, personal traffic flow areas and supply air diffusers can influence containment. A good rule of thumb is at least 10 feet from a door or window and at least 5 feet from a supply air diffuser. ASHRAE 110-1995
  • Fumes and smoke made up of smaller particles create higher, and more severe, exposure risks when fume extraction systems are not implemented. While laser cutting and plasma cutting vary in application, they both require fume extraction systems to capture and filter contaminants at or near the source.
