High Vacuum Dust Collection
Keeps
High Volume Welding Up To Speed
A West Coast manufacturer of car and truck bumpers for OEM
and aftermarket customers was experiencing excessive amounts
of in-plant smoke and dust generated by robotic welding in
its assembly area.

The robotic units operate 20 hours a day, 6
days a week, consuming nearly 5,000 pounds of weld wire per
month. The resulting high levels of weld fumes, smoke, and
dust caused potential for worker health and product quality
problems. To address these problems the company first considered
a large, water wash industrial electrostatic precipitator
with a custom-made canopy hood collection system over each
welding booth. This approach was expensive, required downtime
for setup and had potential to interfere with the robots arm
movement. Instead, the company installed a small, cartridge-type
vacuum dust collection unit. The unit, however, had no self-cleaning
function, requiring frequent filter change-outs and higher
than expected replacement filters and man hour costs.

The Airflow Systems Answer
 |
| Before Airflow Systems V Series in operation. |
 |
| After Airflow Systems High Vacuum V
Series in operation. |
Looking to avoid the expense of a larger
system, while still providing high vacuum collection, the plant
manager met with the local Airflow Systems distributor who recommended
a test program using an Airflow Systems V2 High Vacuum Cartridge
Dust Collector. The V Series provides high reliability and low
maintenance with source capture of contaminants at efficiency
levels up to 99.97% with HEPA after-filters.
Positive Proof of High Vacuum
Effectiveness
After just one month the company was impressed by the Airflow
Systems V2 high vacuum performance and ordered two Airflow
Systems V410 dust collection systems with the Vibra-Pulse®
self-cleaning feature. Installing Airflow Systems V410 units
saved the company over 50% of the cost of its original canopy
hood proposal. The high vacuum V410s also proved powerful
enough to accommodate a variety of process equipment used
in their fabrication and assembly operations. The self-cleaning
feature of the V410s extended filter life to an average of
6 months, reducing downtime and maintenance expense. The Airflow
Systems design was also able to integrate with the robotic
arm eliminating the concern over interference with
the arms movement.
