The Most Advanced Barrel Fan Ever Created

Built to deliver mobile comfort to virtually any space, Sidekick is your facility’s best choice for immediate airflow on the go. Its six-blade design and permanent-magnet motor move more air than any barrel fan on the market with class-leading energy efficiency and the quietest sound level.

Lightweight and impact-resistant, Sidekick offers optimum maneuverability with four locking swivel casters, a large handle, and convenient 12-foot power cord. At 4 feet wide, Sidekick is sized just right for the power you need and easy to store when not in use.

More Airflow, Less Energy

Sidekick’s permanent-magnet motor moves more air at nearly double the efficiency of its closest competitor. With a magnetron core, it also runs cooler than induction or belt-driven motors, ensuring a long life of peak performance.

  • Smaller, lighter, and more powerful than any other fan motor in its class
  • Brushless DC motor design further reduces friction and energy loss
  • 100% passive cooling keeps operating temperature low and efficiency high

Quiet by Design

Sidekick’s smooth, quiet operation is no accident. We engineered the fan with a vented shroud to reduce noise, and its six-blade design provides consistent airflow with none of the choppy sound common to three-bladed fans.

Built Like No Other

Features such as a patented airfoil system, variable speed direct-drive motor, and impact-resistant frame are what set Sidekick apart from the barrel fans of yesteryear.

  • Sleek, durable reinforced nylon airfoils
  • Fully adjustable variable speed control dial
  • OSHA-compliant steel screen and HDPE shroud

Maximum Mobility

Versatile? That’s Sidekick’s middle name. Its convenient 4-foot diameter fits easily through standard interior doorways, while its four locking swivel casters and 12-foot power cord make cooling airflow quick and convenient anywhere in your space.

Rated 5 out of 5 by from Big Ass Fan SIDEKICK We saw the ad's and jumped on the initial batch. This was our first BIG ASS FAN product and we are truly fans! We've tried all those "blah blah" bay fans as well as the usual depot/freight ones. They all fell short. It wasn't a matter of money, even the most expensive ones they carried, moved very little air. Seems as though CFM and all these ratings aren't really accurately documented. It's almost like purchasing a car amp that has 100000watts and some blue neons in it. We thought all hope was lost until we stumbled onto this fan. THIS BAD BOY IS AWESOME! We have a rectangle sized warehouse about 5000 sq ft. We have this thing right outside the main bay door blasting air in. It's crazy to say that even past half way in, you can still feel the fresh air. This was a little splurge of a purchase but worth every penny. We were debating on getting some of the ceiling ones, but this solved all our problems. Fresh air inside a muggy warehouse is the best. The build quality of the fan is fantastic as well. Everything seemed quite nice, the packaging and unpacking was nice. Casters roll nicely as wel.. The ONLY thing I can say that is negative is the operating temp. On hot days, I'm scared to screw up the fan by operating it outside it's operating temp. I know what you're thinking, does it really matter? Some of their high models have a higher temperature rating. Besides that, this thing is A W E S O M E. We would highly recommend this to anyone looking to cool down their warehouse. The fresh air is nice. If it's a little chilly out, the warehouse now gets too cold. And I wish I had this 15% deal when we ordered..

Rated 5 out of 5 by from If Chuck Norris was a Big Ass Fan… Well built and an absolute must-have for outdoor spaces. I was worried because there wasn’t much online defining how quiet it really is. Sitting 15’ - 20’ away, at 30% speed it is dead silent and gives a great breeze. At 60% it’s moving a ton of air but you can still carry on conversations. At full speed it’s a bit louder but it will blow the napkin off your lap. I’d bet money both my brother-in-law and father-in-law buy one.

Rated 5 out of 5 by from Awesome!!! This this thing is great. I bought the AirEye and that was a horrible mistake. The sidekick is superb. It is so quiet at high speeds. It is so easy to move around my garage. If it gets dirty, I can hose it down. If you have the space for this 4 foot diameter fan, then look no further. The SideKick is it. This should last me a lifetime.

Rated 5 out of 5 by from Big Ass Man likes the Big Ass Fan Sidekick This fan moves some serious air and is so much quieter than most other barrel fans. I like that you can "dial" your speed instead of getting 3-4 settings. There is no assembly required. Once you unbox it is ready to go.

Rated 5 out of 5 by from great fan for family fun I purchased this fan to sit by the pool on hot days. I live in the midwest, so I knew a swamp cooler would not work well. I find that my family and I spend more time by the pool since we have a constant breeze.

Rated 2 out of 5 by from Not bad but flaws on pricing Very happy with fan but when on sale 2 days after for $400 cheaper and hand rail is mounted on wrong side. Really needs 2. Quiet and powerful though
