The Double K CHALLENGAIR 850 High-Velocity Stand Dryer is the most effective and versatile dryer on the market. The CHALLENGAIR 850 has no heating element due to the “flow‑thru” motor configuration. The air is warmed by the operational heat of the motor, which saves electricity and produces heat up to 45 degrees above room temperature.

The high-velocity air in concert with the “Air Sweep” nozzle will blow the water from the animals' coat and dry them faster. The CHALLENGAIR 850 Animal Dryer offers great versatility using the assorted nozzles for the desired effect. The stand model can function as a conventional “Fluff” dryer, forced air dryer or cage dryer at the operator's discretion.

Key Features:

  • Twist‑on hoses and nozzles included in a two-year warranty

  • Powerful air volume - motors produce up to 248 cfm.

  • Sound damping foam lining reduces dryer noise.

    Double K (DB) - Ships From Chatsworth, CA

    • The current lead time for all Double K items is 5-6 weeks for fabrication with additional time for shipping depending on your geographical location. All items are made to order, and there are significant logistical issues due to the macroeconomic effects of the COVID-19 on supply chains worldwide.
    • Ships Via UPS Ground. Add Transit time using map below:



    We offer free shipping on orders over $99.

    We know that high-quality pet care equipment is heavy and we do not want shipping costs to be an issue when you buy from us. That’s why on most orders over $99, shipping is 100% free!
    Please note that in some specific situations, unfortunately, we cannot offer free shipping. These include:
    • International orders
    • Orders shipped outside the contiguous United States
    • Some brands such as TK, Rhino and Owens have a higher minimum order amount to qualify for free shipping (their items are much larger and heavier than typical orders)
    • Very large items (e.g., kennel fences) that must be shipped via large industrial freight trucks, when shipped to a non-commercial address or an address with limited access. (On these we still cover the shipping costs, while the customer pays the freight company’s additional delivery fee – usually $70 to $80 on most orders)
    We want to make sure you have all the relevant shipping cost information when placing your order. So if you have any questions, please get in touch!
    Write to us at, call us at 1-855-PET-PRO1 or you can message us on Facebook!

    We pride ourselves in maintaining excellent communication between our suppliers and our customers.

    Please take some time to review our shipping process to know exactly what to expect when placing an order with us.

    Order Confirmation

    As soon as you place your order you will receive an order confirmation e-mail and we will immediately notify the appropriate supplier to begin processing your order.

    Item Availability

    While we almost always have the most up-to-date inventory information, there are rare occasions in which an item may be unavailable or on back-order. If the item is unavailable, we'll let you know and give you the option of receiving a refund or ordering a similar item. If the item is on back-order, we will contact you directly and provide you with an updated shipment date. From there you may either choose to cancel the order or continue with the updated shipment date. Certain made-to-order items may have a longer than normal lead time. If this is the case, the lead time will be specified on the product page.

    If you would like to confirm the availability or potential lead time of an item prior to purchasing, please email us at or call us at 1-855-PET-PRO1.

    Delivery Estimates

    For standard orders we normally ship within 1 to 3 business days and you can expect to receive your goods in 3 to 10 business days total. Please allow 1 to 3 weeks if your order is large and must be shipped by LTL freight truck (as opposed to standard carriers such as Fedex or UPS). For custom orders that require fabrication by our manufacturers, please allow 2 to 4 weeks for fabrication and shipping. Please note that some items may either be on back order with our manufacturer or require more weeks for fabrication and lead times may be longer than 4-6 weeks (especially larger metal items) - these will typically be flagged on our product pages for that product if that is the case. If you are not sure about shipping times for your product or require a rush order, please contact us and our team will check with the manufacturer to confirm shipping time for your specific product or variant. In all cases, to ensure we meet your shipping time needs, please just contact our team at or 1-855-PET-PRO1.

    Shipping Confirmation

    We ship from warehouses all across the country, depending on the item(s) ordered and your location. Depending on the physical size of your order, items will ship either by freight or a regular parcel carrier such as USPS, Fed Ex, or UPS.


    LTL (less-than-truckload) Freight is used when shipments are 120 lb+ or for oversized equipment, which results in a truck with a large container delivering your order. Our freight carrier will contact you once your order makes it to the distribution center closest to the delivery address specified, and set up an appointment time for delivery.

    Pet Pro Supply Co. Free LTL Freight Shipping - Curbside Delivery

    Our standard Free Freight Shipping option for LTL deliveries is curbside, which is to a delivery to a Commercial Address and does not include a liftgate. If your order is to be shipped freight, you will have the option to specify whether the item will be delivered to a Residential, Limited Access, or Commercial address. If there is no option to select a shipping location, then this cost is already included in the price.

    We strongly recommend adding the optional Liftgate for all deliveries to locations without a loading dock or forklift.

    Freight Delivery Locations

    This option specifies whether the delivery location is a Commercial, Residential, Residential Business, or a Limited Access address.

    • Commercial - These addresses are those defined by our freight carriers and/or zoned by local municipalities as commercial sites. Typically these addresses are zoned as commercial real estate or are used exclusively for business. Most commercial sites have tractor-trailer access and a loading dock.
    • Residential - If the address used a residence, select this option. This includes Apartment/Condo complexes and dormitories.
    • Residential Business - Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a Residential Business.
    • Limited Access - Locations where deliveries are restricted, limited, or very far from a distribution center. Examples Include:
      • Place of Worship
      • Restricted Areas - Secure Research Facilities, Military Bases/Installations, Correctional Facilities, Government Buildings
      • Farms, Ranches, and Rural Areas
      • Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
      • Individual Storage Units
      • Sites - Convention Centers, Construction Sites, Mines
      • Schools and Universities
      • Commercial establishments not open to the walk-in public during normal business hours

    Freight Liftgate

    A liftgate is a hydraulic lift that is attached to the back of a truck that can lower freight to ground level. Freight carriers prevent their drivers from assisting with the unloading of heavy equipment other than using a liftgate to ground level. We highly recommend any delivery address without a loading dock, select this option.

    However, please know that for certain very long items, such as Kennels over 6' in length, a Liftgate will not be able to bring the entire order down to ground level. Please have the necessary manpower available to receive your items with limited delay to the driver.
