Select the right air compressor


Compressors is a useful tool for homeowners in the garage or workroom, and they are the necessary equipment in commercial stores, factories, and on job sites everywhere pot. They provide great flexibility and help in getting all kinds of work done. This buying guide will discuss the use of compressors and their different sizes to help you make an informed decision on your next air compressor purchase.

Compressors are used for two main functions. The first is inflation. Around the house, they inflate bicycle tires, sports equipment, air mattresses, some kind of lake, and some of the toys used in the pool. In automotive garage, compressors inflate tires but also be used to blow out clogged lines or dirty air filter. The second use is to drive the compressor air support tools. Just about any power tool can also be found in an air-powered models, including drills, saws, sanders, spray cans, wrenches, and much more. Engine air compressor is powered by a stronger, faster, and more durable than electric models, making them an attractive option for homeowners and contractors.

Homeowners use a compressor to inflate operating items and air tool will do a good occasion for one of the small air compressors have enough light to carry, or a small handheld unit. These will have enough power to run a paint sprayer, nail gun Small crafts finish carpentry, or gas drilling. Contractors use regular air compressor to run tools or for cleaning small things like water or dusty computer, will be well served by the mobile model is often called “hot dog” or “cake” model.

They will drive any air tools, including a nail gun frame or a ratchet wrench / impact, though will only power a tool at a time. These units will increase tire, too, although not as fast as larger air compressor. Growers and small engine repair shops make good use of them to maintain or repair tires lawn care equipment.

Where compressors are used all day long, or for powering more than one tool at a time, a large single-stage, two-stage units will serve you best. Heavy duty air compressor with a large tank will easily inflate a tire that does not slow down, and they will run two or three frame nail gun or spray paint at a time, making them a reasonable choice ideal for builders, contractors paint. A large number of portable compressors, while others often stand in the garage or mounted on a truck at the construction site. Shop for compressors should be based on your needs, and you will see there are many quality compressors from which to choose.

  1. Buy an air tank with a mounting plate on the top of the tank. An example of this would be found in the first link in the Resources section below and comes from Granger Industrial Supply. Measure the holes for the air input and safety valve, as you will need this information later in the build.
  2. Bolt the compressor to the mounting plate using 1/2 “14 TPI bolts and nuts about 1.5 inches long.
  3. Purchase a horizontal shaft gasoline engine of at least 5 horsepower rating. It must not be a gear reduction motor. Set the gasoline engine on the mounting plate. Carefully align the drive pulleys and measure the distance around the outside of them where the drive belt will be. With this measurement in hand you are now able to purchase and temporarily install the drive belt.
  4. Mark the location of the engine mounting holes on the mounting plate and remove the engine.
  5. Using a center punch, make a punch mark at the center of each engine mounting holes location. Make another punch mark ¾” fore and aft of these marks. Then, drill all 3 holes at each location using a 7/16″ drill bit.
  6. Use a rotary tool and join the three holes to form a slot. Do this at each engine mounting bolt location.
  7. Place the engine back on the mounting plate and install a 3/8″ by 16 TPI by 1.5″ bolt at each mounting hole. Do not tighten too much just yet.
  8. Install the drive belt on the engine pulley and compressor pulley.
  9. Slide the engine back in the slots on the mounting plate until the belt is tight. You should be able to push the center of the belt down about ½” when the tension is correct. Tighten the engine bolts securely.
  10. Make belt safety guard by forming 2″ x 48″ 16 gauge sheet metal are around pulleys and belt. Allowing at least ½” clearance between guard and belt. Cut to the proper length after forming and join the ends with two 3/16″ pop rivets. Form brackets from the same sheet metal and attach to the engine and compressor. Close the front of the guard with the hardware cloth, pop riveted to the sheet metal guard.
  11. Install the unloaded valve (see the third link below as an example) in the airline threads on the compressor.
  12. Mount the throttle control valve (the fourth link below leads to one) on the engine. The exact mounting will vary by engine model, but generally the throttle control valve will mount on the throttle plate of the engine and connect to the throttle linkage with a rod or cable.
  13. Connect the throttle control valve to the unloaded valve with ¼” nylon airline tubing and compression fittings. Clamp the air line tubing to the engine using cable clamps to secure it and help support the throttle control.
  14. Screw the check valve into the air in-port on the tank. The correct size for the valve will be the measurement of the air in-port of your air tank, minus 1/4″.
  15. Install a brass pipe tee to the check valve. The tee will be the same thread size as the check valve, which will be either 1/4″ or 3/8″. Mount the tee to the check valve with one opening to the side.
  16. Install the air pressure gauge in the side opening of the brass tee.
  17. Install the male air hose fittings in the one-foot-long piece of 3/8″ air hose and secure with hose clamps.
  18. Connect the brass tee to the unloaded valve using the one-foot-long piece of 3/8″ air hose..
  19. Install the safety release valve in the tank. It will screw in to the port.
  20. Check the oil levels in the engine and compressor.
  21. Start the engine and check for proper operation of the throttle.
  22. Check for air leaks.

Easy air compressor maintenance

Air compressors not only a convenient tool we use in the home and garage of us, they are investments, and to get the most out of your investment, you need to correct the only way maintain it. Here are some tips to maintain the air compressor easily, you can use to ensure your unit lasts for years to come.


Clean All Intake Vents

This is one of the most important things you can do to keep your computer functioning properly. Dust and particles in the air can wreak havoc on your equipment by clogging the vents. Check frequently and gently clean any of obstructions from your vents.

Check the Hoses Regularly

Your pipe is like your compressor arteries – without them your device may not function properly. Hoses are one of the first things to go because the materials from which they are made and the rigors that they are going through in the store and garage. Check your pipes regularly and look for any possible weaknesses or creasing. If you find any, replace the hose immediately or risk unnecessary stress placed on your computer.

Drain Moisture from Tanks

Compressor is a process and in this process, your computer will collect moisture. This is especially true in the summer months when more humid climate, or if you happen to live in an area of the country suffering from year-round humidity. All compressors come with a special valve to release air and moisture out of the tank. Check weekly and drain when necessary. This is one of the most important things you can do to maintain your equipment and ensure a long life.

Change oil

If specific compressor oil you use, you should always head it off before using it. And, like a car, you will need to completely change the oil often. A general guide is the oil should be changed after 500 – 1000 hours of use.

Tighten All Fasteners

The more you use your compressor, the more likely it will be that nuts and bolts become loose over time. This will cause the machine parts to rattle and move in ways not intended, which can cause unnecessary wear and tear. Be sure to check periodically turn nuts and bolts of your compressor and tighten any loose belongings were.

How to Choose Air Compressor for Industrial Needs

Air compressor is the key machine in the all types of industries. Even if you own only a small industry, there should be an air compressor required for different purposes. So, you need an air compressor with good functionality and less cost to buy it. That’s why we are going to give you the importance knowledge for you to buy a new air compressor for your industrial needs.

Air compressors have numerous applications in industry and are used in various fields, including automation and assembly, chemical manufacturing, agriculture and construction. All compressors work by converting power from an external source, such as an electric motor or diesel engines, into stored energy which can be released in the form of pressurized air. The pressurized air is then used to power tools and machinery.


Identify the Uses for your Compressor

First of all, you need to know what compressor is needed and what type of work does it need to follow. As with most power tools, there are many different types, makes and models of air compressors that you can choose from. To make sure you choose the best air compressor that is most suited to your needs, there are many factors to consider that will influence your purchase.

The next thing you should do is to decide what exactly you intend to use the compressor for. For example do you just need a simple model for inflating car tires, or do you plan on using it for various carpentry air tools, or mechanic’s air tools such as pneumatic impact wrenches.

How to Choose the Right one?

Choose the right one is not any easy thing for all of us. So, we need a perfect knowledge about the product that we are going to have it. However compressors vary in their method of operation, air capacity and level of pressure that they can deliver. The right compressor will able to hold enough air and deliver a high enough level of pressure for the task, but performance should be balanced against considerations such as cost and durability. Compressed air is measured in cubic feet per minute (CFM), with a high requirement for CFM needing a larger air capacity and higher horsepower (HP). You can choose the right one for your industrial purpose by following the information we given below for you.

Types of Industrial Air Compressor

First of all, we need to know the different type of air compressors that are widely used in the present world. There are three major types of industrial air compressor based on the method of operation. These are reciprocating compressors, rotary screw compressors and centrifugal compressors.

  1. Reciprocating

Reciprocating compressors are positive displacement compressors, where air is reduced in volume to increase its pressure. Reciprocating contain pumps driven by pistons with a cylinder compressing and displacing the air. There are two types, direct drive compressors and belt drive compressors. Belt drive compressors are more durable and able to deliver higher pressures.

  1. Rotary Screw

Rotary screw air compressors also work by a positive displacement process. They use two helical screws meshed together to force air through and compress it. The method of operation is a smoother process than that of pistons, with less surges and vibration than that sometimes found in reciprocating compressors. They are durable and easy to maintain.

  1. Centrifugal

Centrifugal air compressors work by a different mechanism. They use the momentum gained from a rotating disk to transfer and pressurize air. This process is known as dynamic displacement and is a continuous process, resulting in a steady supply of pressurized air. They can deliver extremely high pressures. However the method also requires higher speeds and higher air capacities than other compressors.

Size Matters

As mentioned earlier, you should think about how you intend using the compressor to determine what capacity or size of tank you need. The air demands of different tools varies significantly, for example simpler types (such as nail guns etc..) only require intermittent use, and don’t have very high flow requirements.

Oil -Lubricant or Oil-Free

Air compressors can be quite complex tools, and need a bit of maintenance TLC to keep in tip top working order. Some require more maintenance than others however, specifically the ones that are oil lubricated.
