To select the right air compressor for your needs, you must understand your application and demand for air. The right type and size compressor can help you reduce energy costs and optimize productivity. Here’s how to get it right.
Compressed air flow is typically measured in cubic feet per minute (CFM) or liters per second (l/s). Compressed air pressure is typically measured in pounds per square inch (PSI) or bar. Think of flow as the ability to perform a process within an acceptable time frame, and pressure as the ability to support multiple processes at once.
A compressor that’s too small won’t produce enough flow and pressure to complete required tasks. A compressor that’s too large will cost more to buy and operate, and can lead to mechanical problems. Right sizing a compressor requires real data about your needs, not guesswork. Whether you’re upgrading your current compressor or designing a new system, ask a compressed air sales professional to conduct an air system audit to measure your actual demand.
If you’re planning for future capacity, keep in mind that a compressor should be sized to address actual demand. Instead of anticipating potential future demand by oversizing today, add a compressor when the time comes to provide flexibility and redundancy as your operation expands. Also keep in mind that process improvements often reduce air demand; you may be able to expand your operation without expanding air production.
Most commercial air compressors designed for commercial duty are either of two types: piston or rotary screw.
