Here at ToolsToday we offer a wide range of air compressors, with everything from your small domestic direct drive air compressors right up to large three phase compressors and screw type air compressors. We offer quality compressors at both ends of this scale at a competitive price. Many businesses rely on compressed air as it's power source, so picking the right compressor in this case is essential. Our sales team can offer you expert advice to make sure you choose the right air compressor.
Choosing an Air CompressorYou should base your choice of Air Compressor around the Air Tools that you wish to use. Different tools will require different air pressures and volumes of air to run efficiently. Pressure is measured in bar or P.S.I (pounds per square inch) and volume usually measured in C.F.M (cubic feet per minute)
If you already have your Air Tools, you need to check what pressure they run at and how much air they require so you can buy an Air Compressor to suit. If you are planning to buy the compressor and then the tools, check the tools you intend to use before you buying the compressor.
For example, the Sealey SA31 Air Riveter uses 4.2cfm of air and operates at 90 psi, so you will need to buy a compressor which meets this requirement, it is always advisable to try and have around 30% more cfm than you need, so that the tool runs efficiently at all times and the compressor is not being over worked.
Take into account which tools you may look to use in the future, even if not at the current time. If you think you may be doing paint spraying for example, you may find it a better investment to go for something bigger than what you currently need, so check out the tools you think you’ll need long term before buying
If you do plan to spray vehicles, we recommend at least a 50 litre 3.0hp compressor, for short stints (panel at a time) and considerably larger for more prolonged regular use, spraying uses a lot of air and requires a smooth flow if you are to get a good finish.
Things To Look Out For..
Tank size: The bigger the tank the more air you can store and the less your motor and pump will have to work. Make sure whatever you buy will fit in the place you want to keep it.
Motor Power: The bigger the motor, the quicker your compressor can build up air and the higher the level that air flow can be kept constant at.
Voltage & Ampage: Make sure if you are buying a large Industrial Air Compressor that you buy the correct voltage, 400V is a three phase, electricity supply, so make sure you have this installed or are prepared to get it installed before buying. Some 230V compressors will run from a higher ampage (e.g. 16A, 18A or 32A) due to their motor size, this is not a big job to install, but will require an electrician if you do not already have it. 230V 13A can use a standard household 3 pin plug.
Piston Displacement & Free Air Delivery (F.A.D): These are both measured in cfm, but piston displacement is the volume of air produced at the pump and the free air is the actual volume of air that the compressor will produce (F.A.D is usually around 25-30% lower than the piston displacement)
