Double K Industries Challengair 850 Instruction Manual Download Page 2

STAND MODEL ASSEMBLY

Your dryer is packaged in two boxes. Your boxes include: 

Box 1

: The dryer body. 

Box 2

: Stand base with casters, 

Y-Bar, stand assembly, two 6’ twist-on hoses, one arm extension, one air diffuser, 3 nozzles, 2 hose-to-cage 
attachments with tie-wrap fasteners and 2 hose adaptors. To assemble your dryer, first attach the Y of the 
Y-bar between the washers on the knob post. The Y-bar slot has a slight angle to it and should be positioned 
pointing toward the front of the dryer. Make sure the electrical cord exits toward the back of the dryer and the 
back of the Y-bar. Re-tighten knobs to hold dryer at desired angle. Attach the arm extension to the dryer body 
by loosening the finger nuts around the upper air outlet on the dryer body. Align the holes in the arm extension 
with the bolts in the dryer face. Tighten finger nuts securely for a snug fit.

Assembly of Stand

The stand tube assembly is pre-assembled and wrapped in paper. The stand tube assembly is compressed and 
held in position by the center clamp. Loosen the handle on the clamp and allow the spring to extend the tube 
assembly. Place the end of the larger outer tube down into the center of the stand base. Twist and push down 
firmly. Lift the dryer head assembly, and position over the assembled stand and slide the tube of the Y-bar into 
the upper stand tube. With clampling handle still loose, raise or lower dryer to desired height and tighten stand 
adjustment handle as explained in the  next paragraph.

Stand Height Adjustment and Dryer Angle Adjustment

Your dryer has “rachet” type adjustment handles on the stand 
and the dryer. To tighten and adjustment handle, turn the 
handle clockwise as far as is comfortable. As necessary, for 
additional tightening, pull the handle out to disengage the 
“rachet” and while keeping the handle pulled out, turn the 
handle counter-clockwise to a suitable position for continued 
tightening. Release the handle to engage the “rachet” again 
and repeat these procedures until the adjustment handle is 
tight. Reverse the turning direction of these actions to loosen 
the adjustment handle. 

NOZZLE

: The nozzle at the end of the 

extension arm may be rotated to change the direction of the 
airflow. Simply rotate nozzle to the desired direction. 

PORTABLE MODEL

Your portable 850 should include: 2 - 8’ twist-on hoses, 1 air 
diffuser, 3 nozzles, 2 hose-to-cage attachments with tie-wrap 
fasteners (4 with dual air outlet dryers) and 1 hose adapter       
(2 with dual outlet dryers).

CONGRATULATIONS!

 on your purchase of the 

Double K Challengair 850/850-XL Forced Air 

Dryer

. The Double K Challengair 850 and 850-XL Dryers produce high-velocity warm air under pressure to 

make your grooming tasks easier. Your new dryer is designed to provide long, reliable service.

The 850 and 850-XL are available in both stand and portable models. The stand model is equipped with a 
grooming arm for use during table drying. The 850-XL model produces 15% more air than the 850. Both are 
available with a variable speed option for greater air flow control.

Please read this manual carefully and completely before beginning operation of your dryer and keep in a 
convenient and safe place for future reference. A warranty card is included with your dryer and should be filled 
out completely and mailed to 

Double K Industries

 within 30 days of the purchase date of your dryer to 

validate your warranty. Online registration is available at 

www.DoubleKIndustries.com

.

Your 850/850-XL Challengair Dryer has brush-type motors (Both models have two motors). It is important that 
the brushes be changed when they become worn down, to prevent damage to your dryer motors (Brushes are 
a maintenance procedure not covered under warranty). We suggest checking the motor brushes after every 
600 hours of dryer use. Please see section on “

Maintenance -Brushes

” p.7, in this manual, for instructions.

A NOTE ABOUT HEAT: 

Your Challengair 850/850-XL dryer has no heating element. The Challengair 

produces heat by a “flow-thru” motor system, meaning the air is pushed through the motor and is warmed 
by the natural heat of the motor that occurs during use. This means greater electrical savings and efficiency 
for you. The dryer will reach maximum heat after about 3-5 minutes of use. Obviously, the greater the 
ambient temperature, the warmer the air from the dryer.
