The Double K Challengair Extreme is a portable animal dryer for groomers removing water and working through undercoat after bathing. Two twin-turbine motor-and-fan assemblies supply the airflow, with each assembly listed at 124 CFM.

Its clamshell ABS housing gives access to the motors for brush changes and service. Noise- and vibration-damping motor enclosures, dual inlet filtration and isolated switches are part of the construction. The hose connects with a half-turn locking motion.

A ten-foot crush-resistant hose and Airgonomic nozzle tips are supplied, including the air-sweep nozzle for moving water off the coat. The Extreme range includes different speed-control and electrical configurations, so the ordered version should be matched to the available power supply and grooming setup. The portable format allows the dryer and hose to be positioned around the work area.
