Airless sprayers are efficient tool used by contractors for various painting, coating, and spraying applications.  But how do contractors choose the right one for their needs? We will explore the most common factors of airless sprayer choose by professional contractors.

Power & PSI

When undertaking bigger commercial jobs, you need a sprayer packing some serious punch to meet the increased demands. Commercial airless sprayers designed for contractors feature more powerful motors, longer hoses, bigger paint tanks and metal parts made to withstand heavy daily use across multiple worksites.

Look for a contractor-grade airless sprayer offering at least 0.75 horsepower or 3000 PSI maximum pressure. This higher power and psi means you can use longer hoses for larger areas, push paint through the line quickly and handle thicker paints or specialty coatings with ease. More power also equates to faster coverage and greater efficiency in getting jobs done on time.

Hose Size & Length

The size and length of hose a paint sprayer can support is another key factor. Standard hose sizes on commercial sprayers range from 1⁄4 inches to 3⁄8 inches. While 1⁄4 inch is good for average residential jobs, having a 1/2 inch hose allows you to spray greater volumes over longer distances without losing pressure or slowing your pace.

Tip Sizes

Airless nozzles are an important part of airless spray systems, aiming to achieve the perfect spray pattern with as little mist as possible, and this is where the material atomizes. You can identify these two key factors by the number on the nozzle. The first digit represents the Angle, which ultimately determines the jet width. The second and third digits indicate the nozzle aperture.

The size of the spray tips the paint sprayer accommodates determines the spray patterns you can achieve. Standard tip sizes range from .015 to .035 inches. Smaller tips around .015 to .021 inches are best suited for finer finish work, while larger tips from .025 to .035 work better for broad wall spraying with more coverage.

Versatility  

To maximize your investment in a commercial paint sprayer as a contractor, look for versatile models that can handle different materials beyond just paint. Multi-use airless sprayers allow switching out spray guns, tips and hoses to apply not just paints, but also sealers, stains, enamels, primers, lacquers and even thicker materials like cement compounds.

Choose airless sprayers with separate air regulators to adjust pressure as needed per coating material for the highest quality finish. Being able to spray joint compound one day and multi-story exteriors the next maximizes versatility and return on your spray equipment.  

Mobility

As a contractor, the ability to transport your spray equipment safely and efficiently between worksites is a must. Look for airless sprayers built with solid frames, all-terrain wheels and built-in handles for maneuverability across terrain. Tilt mechanisms that allow rolling the unit onto wheels like upright luggage also improves mobility.

Other smart design features that ease transportation include tip/line strainer baskets that detach for storage during transit and cords/hoses that wrap securely on the unit. Big all-terrain wheels that handle stairs, gravel, grass and more enable one-person portability for easy in-and-out across job sites.

Durability and Longevity  

Look for metal or advanced polymer-built sprayers rather than plastic consumer models that can crack over time under heavy workloads. You’ll also want to examine key components like the pump, prime valve, filters, hose and spray tip to ensure they are corrosion and abrasion-resistant for longevity even under harsh job conditions and exposure to caustic painting chemicals. Additional armored guards to protect vital components can greatly expand sprayer life.

With the right sprayer, you’ll finish jobs faster and have more flexibility taking on diverse residential or commercial painting contracts. RONGPENG 512 gas powered hydraulic airless sprayers are ideal for contractors. 14L large fuel tank, comes with a high-pressure airless spray gun and high pressure hose, ideal for larger jobs.
