Inflate a swimming pool or a ball, a bicycle wheel, check the pressure of your car tires , use a low pressure paint spray gun to paint small areas, use a blow gun if you are looking for a small compressor to help you out in these occasional tasks that require little pressure and air flow, a portable compressor is perfect.
Operating without oil, light and portable and most often delivered with a lot of inflation tips, we like its attractive price and the services it provides. 1.5 horses (hp) for 8 bars (B) cover the needs.
In the event of prolonged use, take breaks because their small capacity tank (6 liters, 8 l etc.) causes their motor to often start. The mini compressors without tank operate continuously and are for even more occasional needs. You can go for the air compressor at harbor freight there now.
Compressor for household use & small DIY
Inflating, stapling, nailing, blowing with a blower, small paint jobs, gluing, pressure on car tires for longer lasting work but still for domestic use, you can turn to a single cylinder compressor.
Prefer a volume of 50 liters for rapid recharging, a certain autonomy and a moderate engine release. Wheels are essential for its movement to be practical. A flow rate of around 15 m 3 / h with a power of 1.5 hp will be sufficient.
Compressor kits offer pneumatic tools with a suitable working pressure for domestic tank compressors often 8 bars minimum required.
Compressor for regular use
Inflating, stapling, blowing, painting, gluing, drilling, chiseling for DIY enthusiasts who regularly use their compressor, it is essential to have a substantial air reserve and a correct air flow. A tank of 100 to 150 liters and a flow rate of 15 to 25 m 3 / h will be perfect.
The power of the compressor group will range from 2 to 3 hp. If you work in a workshop, you supply a pneumatic network, prefer a fixed compressor.
If you tinker in various places or outside, choose a wheel compressor, preferably inflatable for greater maneuverability.
Professional compressor
There are all basic works as well as the use of pneumatic tools such as impact wrench, sanding machine, sander, grinder. For intensive use with large air requirements, a tank of 200 liters minimum with a flow of at less 40 m 3 / h are ideal.
The power will be at least 5.5 hp. Prefer a compressor with a stage compressor group to guarantee a continuous air flow and a comfortable pressure. With such characteristics the compressor will be fixed.
In a professional workshop, a three-phase 400 V compressor is a good choice. If you need mobility, then you will need to turn to a “trailer” type compressor equipped with an internal combustion engine.
Points to remember to make the right choice
The tools operating continuously require a larger tank to avoid a continuous triggering of the engine which generates a noise nuisance and premature aging of the compressor (the main tools: pneumatic sander, pneumatic gun (to paint large areas), sandblaster, chisel etc.).
The air flow (l / mn) and the pressure (bars) are to be chosen according to the tools that you will use (cumulate the flow rates of the tools if use of several at the same time). Multiply this flow rate by 1.5 for comfortable use and add 2 or 3 B to that required.
