You to choice a suitable portable air compressor depends on your job requirements. Portable compressors have increased in popularity and are now available in a variety of power / size categories.
The following factors should be considered before you spill your monies on a compressor.
» 1. Demand user.
First, you need to determine exactly need to use air compressor for the your job. This is necessary to avoid you have to buy many different compressors or to user a compressor not enough capacity order to work and vice versa.

» 2. Size and Weight.
Portable air compressors are available in different shapes and sizes. The smaller ones are easy to be hand-carried around in a storage bag, while the larger ones have wheels under them allowing them to be moved. A light lubricant free compressor, with a capacity of 2-6 gallons, will do a good job if you require tire inflation or nail gun finishing to be done. However, if you need to frame a nail gun or similar heavy duty work, you will require a larger (wheel barrow) portable air compressor, which is powerful and yet easy to move around. The size naturally increases as the nature of your work gets tougher.
» 3. Power Source:
You can choose between fuel and electric powered motor. The electric powered motor usually runs on the household voltage and as there is no fume emitted, electric compressor becomes an ideal choice for indoor work. On the other hand fuel powered motor emit exhaust fumes and is usually used in the more powerful machine which make it more suitable for outdoor works.
» 4. Horsepower.
While not as imperative as the SCFM rating, a compressor’s horsepower (HP) rating can give you a relative feeling of the model’s strength. HP demonstrates how capable the motor is, while the SCFM rating lets you know how much power the compressor really gives to your tools. Compressors for the most part have HP drive between 1.5–6.5 HP. Stationary oil-greased compressors with a rating over 2 HP need a 230/240v energy source to supply the high volume of air required for the high utilization in tools like sanders, processors and sandblaster.
» 5.SCFM Rating:
Once you’ve decided on the portability and power source for your air compressor, you can determine the device and the brand best for you by judging from the key performance ratings. Perhaps the most important rating to consider is the SCFM (Standard Cubic Feet per Minute) which is the amount of compressed air released each minute. For a fair comparison, look at the SCFM for 90 PSI between different brand products and choose the one which is the most optimum. Smaller work usually requires a SCFM rating between 0 → 5, while larger work requires at least 10
To meter the SCFM ratings you need to observe the SCFM requirements of all the tools you intend to use. Take the product of the highest tool rating by 1.5 to get the least compressor SCFM for your needs. This allows you to have a little breathing space. On the off chance that you hope to work various pneumatic apparatuses in the meantime, you’ll require more power. For this situation, figure the base SCFM compressor by adding the SCFM prerequisites for every device that you’ll utilize. Most light home compressors are intended to power one apparatus at once, however bigger sized compressors can deal with various tools. » 6.PSI:( Pounds per Square Inch)
The pneumatic pressure the compressor produces inside the tank is measured in Pounds per Square Inch, or PSI. Light-work compressors for the most part have 90 psi, which is ordinarily adequate for pneumatic instruments for basic house tasks, including nailers. All the more powerful compressors may produce 150 psi or higher.
» 7. Tank Size.
The size of a compressor’s tank is critical in light of the fact that it decides the duration air apparatuses can keep running before the compressor restarts. Tank sizes are judged in gallons, and keep running from 1 gallon as far as possible up to 80 gallons.
» 8. Pump Type.
You can find a variety of pump types in terms of quality and working. Generally pump is divided into either single stage or two stage. In the single stage, compressed air is produced at the same output pressure. Two stage has two or more cylinders working to compress air while keeping the tank pressure high, letting the device run longer.
» 9. Lubrication Vs Lubrication-Free: Lubricated compressors require oiling to work properly and keep from wear similar to how car engine needs oiling. Lubricant Free compressor is made of non-stick material and doesn’t require much maintenance. It is used more commonly in lighter portable air compressors, compared to lubricated compressor which is used in larger machines.
» 10. Maintenance.
Air compressor proprietors regularly overlook that an ounce of care will make up for giving up cash. Keeping up your air compressor can spare you both time and cash not far off. A few must do’s to take care of your machine includes pump oil level and oil leak inspection (unless it is lubricant free), check for moisture in tank, check for weird noise and vibration, inspect all air leaks, inspect belts, check air filters and safety relief valve, tighten all bolts. Maintenance is needed regularly after every week or so.
Note: Most lubricant free compressors come with lower maintenance requirements compared to oil pump ones.
Accessories need compatible with the compressor. The manufacturers often integrate accessories come with the machine. You need to choose the compressor with accessories can be replaced and search easily in your area.
» 12. Heat Overload Switch.
Shuts off motor in case of excessive heating. In case of internal heating reaching the cut off value set in the thermostat, the circuit is activated inside the motor and it will cut off the supply of electricity to prevent overheating and a possible fire in the machine.
» 13. Cooling Mechanism.
Proper vents are installed which allow the machine to cool down. This also extends machine life as the parts are unable to endure heat, which gathers under length operations, for long durations.
» 14. ASME Certification.
Product meets the high standards of manufacturing and performance as set by American Society of Mechanical Engineers. These products will be more reliable and are usually of better quality.
» 15. Roll Cage.
Protects the motor and pump. This is important especially if you are working outdoors.
» 16. Brand.
There are tons of brands to choose from, with several veteran companies and some new ones, all trying to take a part of the pie, which is the consumer base. So as a consumer you need to make a choice. When you are purchasing a product from a brand you are buying an experience. Look for the brand with a better reputation and great customer service. The most reputed brands are always the innovators and use the modern technology to better equip your device. Also make sure that you are being given a solid warranty for the product. Most cheap and especially Chinese brands come with little or no warranty time which is not what you need. The good brands always have a bold warranty plan.
And finally, is price. The price of a portable air compressor starts from a low 50 US dollars and can go up to a premium 3000 US dollars. While the cheapest ones are for the light works you may encounter inside the walls of your home, the heavy duty ones usually damage your wallet a lot more. It is essential that you prefer quality over price, as this is an investment which usually goes the long run.
Great. Now you can choose a portable air compressor best to using the best for your job. Thank you for visiting my blog. Good luck.
