![]() You may find them in chemical plants or manufacturing centers.The Buying Guide: Our Advice on How to Buy the Best viair compressorīefore you invest your hard-earned money into a product, you should properly educate yourself about the available products and the best alternatives in the market. Centrifugal compressors: They use a multi-stage compression process that produces a high amount of energy.They’re often found on ships or planes and not used in construction. Axial compressors: These types of compressors are expensive.Two types of dynamic compressors include: ![]() They use fast-rotating blades to pull air in rapidly, then create pressure by restricting the air. Single-stage compressors work adequately for small jobs, such as wood or metalwork, but you may need a multi-stage compressor (up to 30 horsepower) for larger tasks such as auto assembly.ĭynamic compressors can reach 1,000 horsepower or more. They build pressure using a piston inside a cylinder, which displaces air. ![]() They are used for tasks such as home construction projects. Reciprocating air compressors: More often found at smaller worksites.Rated at 5 to 350 horsepower, rotary screw compressors generate energy by trapping air between two opposing rotors that turn in opposite directions to build up pressure. They don’t require much maintenance and can be lubricated with oil or run oil-free. Rotary screw compressors: Good for continuous use at large construction sites.Two common types of positive displacement compressors include: Positive displacement compressors store air from the outside in an internal cavity, where it’s slowly compressed. Within those categories, there are multiple types of air compressors. They need to stop and cool down, or the parts can become damaged.Īir compressors fall into two categories: positive displacement and dynamic compressors. However, reciprocating compressors are not designed for continuous use. Rotary screw compressors, discussed below, have an internal cooling system that enables them to operate continuously. How long can you leave an air compressor running?ĭepending on the type of air compressor you’re using, it can be left running anywhere from a few hours to 24 hours a day (seven days a week for compressors on ships or planes). The tools you need for each of these jobs will likely require a different CFM-more for heavy-duty jobs that require a continuous flow of air. The average drill requires 3-6 CFM at 90 PSI and the average orbital sander requires 8-12.5 CFM at 90 PSI.Ĭompressors can power an array of tools for tasks including sawing, nailing, chiseling, cutting, painting, and sanding. The easiest way to determine what size air compressor you need is to check the air requirements on your tools. ![]() Exact rates may vary depending on your worksite location.Ĭheck for quotes on other compressors that BigRentz offers including 375 CFM and 750 CFM machines. A larger 1,600 CFM compressor that can provide air at higher PSI for an extended period will run you $710 a day, $2,031 a week, or $4,914 a month. A 185 CFM diesel air compressor that can power blasting pots or jackhammers can rent for $114 a day, $312 a week, or $754 a month. How much does it cost to rent an air compressor?ĪAir compressor rental costs vary according to size and flow capacity. ![]()
