The Mini Dyna Probe uses a reinforced air hose with a pneumatic motor that runs the air wash and brush simultaneously. This eliminates the need for heavy cables. A single technician can use the Dyna Probe, and he or she can easily maneuver through ductwork, including elbows. The unit comes with 7.5-, 10- and 21-in. brushes. An optional sanitizer and wash system is also available.
