At Profits Unlimited, every piece of equipment — from two-post lifts rated to 12,000 lbs to oil-free compressors running at 60 dB — is selected because it holds up under daily shop use. We stock gear with specs you can verify: CFM, PSI, lift capacity, wattage. Free shipping on most orders within the Continental U.S. (excludes AK/HI), with tracking included on every shipment.
Questions We Get a Lot
Most impact wrenches and die grinders draw between 4 and 8 CFM at 90 PSI under continuous use. If you're running multiple tools or a spray gun, add up the CFM requirements for each tool you plan to run simultaneously and size your compressor at least 1.5x that number so the pump isn't fighting to keep up. Check the product specs on each unit — CFM at 90 PSI is listed where available.
An oil-free pump uses pre-lubricated or PTFE-coated cylinder walls, which eliminates the oil change interval and removes the risk of oil carryover contaminating your air lines or finish work. The trade-off is that oil-free pumps typically run at higher RPM and generate more heat, which is why duty cycle ratings matter — a compressor rated for a 50% duty cycle needs rest time between heavy draw cycles, while one rated higher can sustain longer runs.
Tank size is storage, not supply. A larger tank lets you draw air in short bursts without the motor cycling on, which is useful for intermittent tools like a brad nailer. But if you're running a continuous-draw tool like a grinder or sandblaster, what matters is CFM output — the pump has to keep pace with the tool in real time, and a bigger tank only buys you a few extra seconds before pressure drops below the tool's minimum PSI.

About Our Air Compressors
An air compressor converts motor power into stored pressure, then releases that pressure on demand to drive tools, inflate tires, atomize paint, or clear debris. The right unit depends on three numbers working together: CFM output, maximum PSI, and duty cycle. CFM tells you how much air the pump can produce per minute at a given pressure — this is the number to match against your tools, not tank size. PSI tells you the upper pressure ceiling. Duty cycle tells you how long the compressor can run under load before it needs to rest, which separates a shop-grade unit from one built for occasional residential use. Oil-free designs trade some longevity for zero maintenance and clean air output, making them a practical choice for finish work or any application where oil contamination is a concern. Before you buy, list the tools you plan to run, find the highest CFM draw among them, and buy a compressor with enough headroom to keep up without running at its limit all day.
