MultiSmart™ extraction arm’s unique, clear-thru design gives a completely uninterrupted airflow and the lowest pressure loss of any arm on the market. Maintaining high airflow without turbulence eliminates the build-up of particulate and reduces the cost of maintenance. The safety-encased arm mechanism is outside the air stream producing “one touch” smooth movement combined with outstanding stability. The MultiSmart™ (MSA) is versatile, lightweight and safe, providing unsurpassed airflow with ergonomic design, and easily accessible controls.
