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.

The 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

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.

Source capture arms and local exhaust ventilation systems, such as those offered by Air Quality Engineering, play a crucial role in maintaining workplace air quality and protecting workers from harmful airborne contaminants. Some additional points to consider about these systems:

• Applications: Source capture arms and local exhaust ventilation systems are versatile and can be used in various industrial applications. They are effective for controlling and capturing contaminants like coolant mist, welding smoke, grinding dust, and other airborne pollutants.
• Customer-Centric Design: Air Quality Engineering emphasizes customer feedback and engineering development to refine their source capture arms. This customer-centric approach ensures that the equipment meets the specific needs and challenges of users.
• Ease of Use: Traditional capture arms may have been challenging to position and prone to “springing back.” The new parallel linkage design of these arms addresses this issue, making them easy to move and stable once positioned. This design minimizes recoil, making it more user-friendly.
• Maximized Airflow: These arms are designed with minimal internal restrictions, allowing for maximum airflow. This design feature ensures efficient contaminant capture and removal, maintaining a healthier work environment.
• Longevity: These arms are designed with minimal wear components to ensure a long service life, reducing maintenance and replacement costs over time.

Our source capture arms and local exhaust ventilation systems are essential tools in industrial settings to maintain air quality, protect worker health, and ensure a safe and productive work environment. Advancements such as user-friendly design, optimized airflow, and variety of choices make AQE systems effective and adaptable for your industrial application.
