The Double K Challengair 850 is a portable animal dryer using motor-generated warmth rather than a separate heating element. Air passes through the motor system and is directed through the hose and selected nozzle for coat drying.

The dryer housing is cross-linked polyethylene, with sound-damping foam inside and filters that can be accessed for cleaning. Twist-on hoses and nozzles provide the connections used to configure airflow at the grooming position. The air-sweep nozzle is intended to move water from the coat.

The 850 family includes standard and XL versions and different speed controls. Match the exact ordered configuration before relying on a particular airflow or electrical rating. This catalog entry identifies the portable format; accessories and control options should be checked against that specific package.
