From the team that brought you the industry-changing RY10 Pro Crackfill Machine are at it again! This time they've rethought the air-operated spray system, inventing a powerful, professional machine that will revolutionize your sealcoating business.
If you sealcoat parking lots, then you know you need that unbeatable power and capacity. The AirBoss 300 Air-Operated Sealcoat Spray System delivers, with:
- 304-gallon sealer capacity
- 1.5" dual-diaphragm air operated pump
- 6.5 HP Kohler gas engine, 196 CC
- 2-piston single stage compressor
Getting a smooth finish fast is critical to professional sealcoating. This system has an output of 12CFM. Compare that to spraying with a centrifugal sprayer: you get more power so you can cover more space more quickly.
The sealcoat sprayer's steel tank has manual agitation; 2 rubber paddles attach to a 1.5" bearing shaft. 3:1 gear reduction reduces torque but increases the speed, saving you time and effort. You can agitate sealer with just one arm, so you won't get fatigued keeping your sealer mixed properly.
This sealcoating equipment comes with a 9-gallon compressor comes with a pressure regulator and gauge, delivering a max working pressure of 120 psi and transferring 12 CFM of air flow. You'll complete work faster with this powerful machine.
The 2 piston, single-stage pump has been field-tested to hold up to the toughest sealcoating conditions.
Weight: The AirBoss 300 weighs 1,200lbs empty and 4,240 lbs when filled fully with sealer. We recommend using trucks or trailers with a payload of 5,000 pounds and up. Clients use the F-450, Sierra 3500, Silverado 3500 and Ram 3500, or a trailer to tow this spray system.
What's included: the AirBoss 300 Base Model ships with a 3/4" seventy-five foot hose, and a lightweight, durable 60" aluminum spray wand with a 3/4" full port ball valve. The asphalt sealcoat sprayer's basket strainer holds 3 gallons and features 0.1575" (4 mm) holes to keep particles out of your pump.
The AirBoss 300 sealcoating spray system comes fully assembled on a pallet. Just load it into your truck, add oil to the engine, fill it with gasoline, load it with sealer, and you're all set.
If you're ready to up your game to a high-quality, bulletproof air-operated unit, the AirBoss 300 won't let you down: sealcoat like the pros do with this air-operated spray system.
