The Double K Challengair 9000II is a stand dryer for animal grooming with an adjustable head and a five-legged base. Its one-third-horsepower brushless motor drives a centrifugal impeller, with the manufacturer listing 260 CFM of airflow.

A gas-spring stand assists height adjustment, while ratcheting handles position the drying head. The motor sits beneath the main head assembly, and the nozzle can be positioned from 19 inches to 6 feet 8 inches above floor level. Heat and air-volume controls let the groomer adapt the drying setup.

An intake filter protects the impeller area, and cleanable EZ Roller casters support repositioning the stand. The housing is designed to resist rust and dents. An accessory kit is available separately, allowing the base stand-dryer setup to be expanded without assuming those optional parts are included.
