The Cool Boss CB-19SL delivers 6,840 CFM of cooling with Honeycool™ media, a 15-gal tank, timer, auto shutoff, and more—perfect for garages, patios, and home workspaces. Energy-efficient, compact, and eco-friendly cooling made easy.
The Ultimate Personal Space Cooler
You could spend a fortune on air conditioning just to see your electric bill skyrocket. Or, you could bring home the Cool Boss CB-19SL—an ultra-efficient, low-maintenance evaporative air cooler that’s tailor-made for dry, hot climates. At 6,840 CFM, this thing moves serious air without the serious cost, offering an ideal solution for residential garages, backyard spaces, and home gyms.
It’s not just a cooler—it’s a smarter way to beat the heat.
How Does the CB-19SL Deliver High-Performance Cooling?
At the core of the CB-19SL is a 19-inch axial fan working in tandem with Honeycool™ evaporative media. This advanced media is engineered for up to 30% greater evaporation efficiency compared to conventional pads, delivering increased cooling performance while using less water. The result is a more efficient system that reduces both water consumption and operating costs—without compromising output. Evaporative cooling works best in environments with low humidity (60% or less), and in those conditions, the CB-19SL hits its stride, cooling large areas using nothing more than water, airflow, and basic physics. No compressors. No refrigerants. No guilt.
And if you’re the type to set it and forget it, the CB-19SL has your back with a built-in timer, a variable-speed fan, and a low-water automatic pump shutoff. It even shuts off the water source automatically when you’re not using it—so no more surprise puddles when you fire it up after a few days off. It also includes an automatic water source shutoff to prevent unnecessary flow—eliminating the risk of unexpected leaks or puddling when the unit hasn’t been in use.
CB-19SL – Garage Friendly Cooling
Let’s talk build. The CB-19SL rides on a tough, antibacterial HDPE shell—rugged enough for shop abuse, light enough (just 40 lbs. dry) to move around. Standing 66 inches tall with an optimized footprint, it’s compact enough to stash in the corner but big enough to throw wind across your entire space. Add in the 15-foot power cord and 3-speed fan control, and you’ve got flexibility for just about any setup. Plug it into any standard outlet (or optional 208–230V if you’d like), and get ready to cool off.
How Quiet Is It Really?
At just 57 to 62 decibels, the CB-19SL hums more than anything. You’ll still be able to hear the game, take a call, or carry on a conversation without shouting over your shoulder. It’s the kind of background noise you’ll forget about—until you walk into the breeze.
Why Pick the CB-19SL Over Traditional AC?
Simple: It’s efficient, affordable, and environmentally chill. Air conditioners consume loads of power and use refrigerants that require regular service and regulation. The CB-19SL? It leans on the oldest cooling method in the book – evaporation. No harsh chemicals. Just smart airflow and natural water cooling.
That’s why it’s the go-to alternative for people who want relief without the sticker shock, especially in dry regions where traditional AC systems struggle to keep up. With the CB-19SL, you’re not just cooling your air – you’re saving big.

It’s built to work, built to last, and built to save you money, all while keeping things refreshingly cool. With Cool Boss, hot air doesn’t stand a chance.
