How to choose the best Rolair Air Compressor

Choosing the most suitable Rolair Air Compressor for your specific need does not have to be a challenge. Air compressors power pneumatic tools and sprayers, inflate tires, and clean dust from crevices and cracks, making them a critical part of any job site or workshop. Learn how compressor features affect performance and find the Rolair® Air Compressor to meet your needs.

Factors You Should Consider When Buying A Rolair Model

All About Airflow

A compressor’s primary function is to provide a reliable high-pressure air flow to pneumatic tools or other accessories. The delivered airflow rating, in cubic feet per minute (CFM) at a given pressure in pounds per square inch (PSI), tells you how much air a compressor delivers. The airflow rating of the Rolair air compressor you choose should exceed the air requirements of your highest-demand tools by about 50 percent. If you plan to run multiple devices off a single compressor, add up the air requirements of all tools in simultaneous use to find a unit with sufficient air capacity.

Compressed Air Storage Capacity

All Rolair compressors have one or more metal tanks that store compressed air. These tanks are typically proportional in size to the unit’s airflow rating. The compressor motor runs long enough to fill the tank and then shuts itself off or idle to cool down and reduce noise. A large tank ensures smooth air delivery and offers a longer cooling interval.

Single-Stage and Two-Stage Compressors

Most compressors use either a single-stage or two-stage design. Single-stage models have one piston that pushes air into the storage tank. Two-stage Rolair compressors have two pistons in a sequential arrangement. The first piston forces compressed air into the second, compressing the air further and pushing it into the air tank. Single-stage designs are small and light, making them ideal as portable compressors. Two-stage models deliver large air volumes at high pressure. They’re an excellent choice for high-demand applications such as running multiple pneumatic tools simultaneously.

Transportable Air Provisioning

When choosing a compressor, how you get the unit to the job site is an important consideration. Stationary electric compressors excel in shop settings, while heavy-duty, gas-powered models with truck mounts provide plenty of air capacity for remote locations. Compact compressors like the Rolair JC10 offer convenient carrying handles that let workers take their air source almost anywhere, and larger, wheeled models combine portability with the airflow and tank capacity necessary to take on big jobs. Many portable models also feature roll cages that protect engine components and air fittings from damage if they fall over or are in the path of falling debris.

Gas Versus Electric Rolair Compressors

Both gas compressors and electric compressors come in a broad range of sizes, but there are differences between these products. You can use electric compressors indoors or outside, and they are often quieter than gas-powered models. Many run on the standard 120V household current, but some heavy-duty models offer a variety of high-voltage power connections. Rolair gas compressors, on the other hand, are a solid choice for remote job sites and eliminate the need for extension cords that may create trip hazards. However, they are not for use indoors without proper ventilation for exhaust gases.

All gas and electric compressor motors have a horsepower rating. While this value does not directly affect the unit’s airflow, a robust motor speeds pressure recovery and reduces the duration of tank-filling cycles.

Rolair Compressor Safety Features

Safety is a significant concern when using power tools, and Rolair products have features that ensure safe and reliable operation. A built-in sensor detects overheating and automatically shuts down the motor to prevent damage, and a safety relief valve vents excess pressure from the air tank to avert catastrophic failure. Models with an output regulator give you control over the air pressure reaching your tools, and separate tank and regulator gauges clearly indicate tank and output air pressure.

Pneumatic tools are essential in commercial shops, construction sites, and DIY workshops. Gas and electric air compressors provide the airflow you need to power these devices in almost any setting. Choose the Rolair compressor that meets your job site needs, and enjoy the safe, quiet, and reliable operation these products offer.
