If you’re looking to buy an air compressor, here’s a solid guide on what to check plus a selection of good product options for you. I can tailor further once I know your budget, space and use-case (DIY, workshop, industrial, etc). ✅ Key things to consider before buying Here are what experts stress you need to check: Intended use: Identify what you’ll use it for — tyre inflation, powering nail guns, spray painting, heavy shop tools, or industrial use. That determines the size & specs. Chicago Pneumatic +2 Industry Buying +2 Airflow (CFM) & Pressure (PSI/bar): The compressor must deliver enough volume of air (CFM or l/min) and at sufficient pressure for your tools. If under-sized, it’ll struggle. The Home Depot +1 Tank size / Storage capacity: Larger tank gives you more stored air so tools can run longer without the motor constantly kicking in. For intermittent use smaller tank may be fine. ABAC +1 Power source / Electrical supply: Check your location’s supply (single phase vs three phase, voltage) and whether you’ll need electric vs petrol/diesel (especially if outdoor/mobile). Chicago Pneumatic Noise, portability, maintenance: If using at home or in a small shop, noise matters. Also oil-free vs oil-lubricated, maintenance ease, footprint and portability count. Atlas Copco +1 Quality of air / specific features: If you’ll use it for painting, food, clean work, you might need oil-free air or additional filters/dryers.
