Local Exhaust Ventilation (LEV) / Source Capture Arms

Air Quality Engineering uses proven technologies and a comprehensive range of equipment to control harmful airborne industrial contaminants such as coolant mist, welding smoke, and grinding dust.

2 examples of local exhaust ventilationThe source capture arms from Air Quality Engineering are the result of input from our customers and years of engineering development. We recognize that one of the largest hurdles to using source capture arms is the ease of use. Consequently, our new arms are job-tested to be both easy to move and stable once positioned. While old designs tended to “spring-back” the new parallel linkage design allows the arm to retain its position even when fully outstretched. AND it will eliminate recoil when the arm is positioned closer to its mounting. The arms are designed with a minimal amount of internal restriction resulting in maximum airflow. The design of the arm also incorporates minimal wear components to insure long life.

Features and Benefits:

  • Smooth interior for minimal friction losses and maximum airflow
  • CFD-Engineered hood design for maximum efficiency of capture
  • Both 6″ diameter and 8″ diameter arms produced in 13 foot lengths to meet your needs
  • Optional LED lighted hood for maximum brightness with minimal energy
  • Optional hood mounted blower controls for user convenience and operability
  • Parallel linkage design keeps arm positioned where you want it
  • Easy to position – arm can be placed into position with one hand
  • Optional shut off damper for multiple arm installations

Air Flow Profile

The conical hood design of our source capture arm was the result of an intensive effort to model and develop the most efficient and practical hood design using leading edge computational fluid dynamics programs. These programs use numerical analyses to effectively and accurately model the airflow pattern at the inlet of the hood and maximize the capture velocity as far away from the hood as possible. This mitigates user error and allows for more forgiveness in hood positioning.
