Purchasing an air compressor ปั๊มลม is totally not simple as many people might think. This list contains almost everything people should know when deciding to choose and buy an air compressor.
Purchasing an air compressor can be very complicated for some people who are not the “experts” or “pros”. Therefore, in this article, We would like to make everything simpler for you by giving necessary knowledge and useful tips to help you choose your compressor with ease.
Compressed Air Requirements
If you could not determine which the total CFM requirements are, and at what pressure the compressed air should be delivered, you cannot know which compressor will suit your real need. Therefore, this is the very first thing you need to do.Remember, when you area unit filler a mechanical device, that 1 horsepower of mechanical device output generates concerning four CFM of compressed air at involving ninety PSI.
The following links will give you more knowledge of sizing an air compressor, and if you want to get an air compressor for running air cylinders, this information is suitable for you, helping you to choose a right air compressor with ease.
This is the well-accepted wisdom for an air compressor with the size of over 10 HP. For the compressors with smaller size – about under 10 HP, you should depend on the figures given by the producer or “guestimate” as you are getting around 2-3CFM of compressed air per HP @ 90 PSI.
Available Power Supply?
Notwithstanding the type of the compressor you buy, it definitely must have a power supply. If it is installed in a plant, what amperage’s or voltages will be available for you? To get the needed amount of air, will you need to upgrade the electrical system? Due to the volume of power available in a typical home 120 VAC circuit has limited the size and so does the amount of air from the compressor, if you decide to run multiple tool locations or high demand air tools, you will need to look at 220 VAC systems.If it is a free compressor style, do you want it powered by diesel, gasoline, or perhaps propane? Are there any different power selections necessary or available for you, relying on the place you are in?
Continuous Run Or Start & Stop Compressor?
Whether your air compressor should be continuously running, or it is the type of air compressor which starts and stops depended on the pressure cycle, might be explained relying on your requirements and demand. If it is not clear, you will need to consult the producers to get their benefits for an air compressor which fills a reservoir and stops until the little pressure signals a beginning or one that continuously runs, but just compresses the air when having a demand. Field portable units that usually run on diesel or gasoline, usually continuously run, as the need, to every few minutes, start and stop a fossil fuel motor, is not good for the engine.Compressed Air Losses
You should also notice that, in a typical plant environment, over time, you might lose about 10 percent of the overall air production due to the compressed air leaks or misuse and also due to the pressure drop in the system.You should choose the air compressor from where planning a 5-year-use expectation regarding the compressed air-related demand.
Portable Or Fixed Installation?
Are you looking for taking the air compressor with you to many different job sites or locations, or is your air compressor heading for a fixed installation?There will be a lot of applications for portable air compressors while most plants rely on fixed installations. If that is your selection, you should have a talk and discussion with the vendors about the methods of portability; is the compressor wheeled itself, trailer type; is the air compressor carried, come already installed on a cart or wheelbarrow, etc. You will need to discuss this with the sale outlet of the compressors based on your expected demand.
Financing
You will need to know if there are some creative financing selections available from the different compressor firms to help to attract your purchase to their services.Some might “bring the paper” of the loan, and if they will, and you do not want to get this benefit, might be refusing it will lower the fee you need to pay for the unit somewhat?
Capital cost
How much will you need to pay to buy each type of compressor you have narrowed your list down to?Some might quote delivered your plant, others not, so you will need to put installation or delivery costs to the capital cost of each if the price quoted does not include that. Therefore, all vendors’ prices are cited the same.
Parts Cost
You are looking for a company with a great warranty, backing it up with in-plant service, but you will need to know the parts cost.Once you know UN agency can repair the mechanical device, you should kindle a elements breakdown, get the answer that parts ar seemingly to fail from the seller and asks for the acquisition value you may need to get those elements. There will be vital rating disparities for similar elements from entirely different vendors. Take the time to check as parts value might be an oversized a part of your mechanical device budget as time goes on.
Who fixes?
Do you have someone in your shop who knows how to repair an air compressor when the warranty was over?If not, do you think about who could fix the air compressor then? Are there travel expenses, what the response time is, where their offices are, and how much you will need to pay for an “out pay” service?
Warranty
Not all guarantees or warranties are equally made. To get a contract with you, some producers might have some positive changes on their warranty. If that is the case, you should ensure to get the guarantees in writing.You would be able to save much money on an air compressor which offers a poor warranty, but you possibly find yourself completely replacing it, backed by a secure guarantee, long before a more costly unit, might have been used up.
Life expectancy
How long this particular model lasts when it is used for a normal operating period.If to save some capital expenses up front, you have considered under sizing your air compressor, and end up pushing it over its acceptable duty cycle, how this can affect the compressor’s life expectancy? Will you have to buy another air compressor much sooner than you think?
Maintenance
What is the thing that must be needed and regarded relating to the upkeep for the mechanical device that you just square measure wanting at? What square measure the prices of the numerous consumables every mechanical device may want, for long-term or regular maintenance? What are the mean times between maintenance functions…For instance, if it is an oil lubed compressor, how typically do you have to be compelled to amendment the oil, and what type of oil you'll have to be forced to use? Some producers advocate synthetic oil which can take you costlier expenses. If so, what advantages you will expect if you settle for a better cost?
What Will Come With An Air Compressor?
A producer will have a list of the features included which shows clearly about extra cost accessories.You must consider about building a spreadsheet with benefits and features of each system from the vendors. This is an effective way to compare “apples to apples” from many producers and compressors ปั๊มลม.
Operating Costs?
Your compressed air pressure and supply demands will lead you to choose compressor producers who actually make compressors of the flow and capacity that you expect.After that, the available power supplement might further narrow the vendors list to those who will give you a unit running on the power you already have or which you will make use.
For any electrically driven compressor, sometimes greater voltage units generate compressed air with the cheaper fee. You should ask the vendor for the available voltages, and ask for the advantage because it pertains to decrease the operating cost based on that voltage.
Might be you can see that a propane unit releases lower operating cost than gasoline for a mobile unit.
