Auto 20 bar air compressor

Types of 20 bar auto air compressors

The air compressor works by drawing in ambient air from its surroundings and compressing it into a storage tank. The process happens through a motor-driven pump or tension spring. The motor of an air compressor is powered by electricity, gas, or solar energy. Once the air is compressed, it increases the pressure within the tank. Valves and pressure switches control the release of the compressed air and its flow rate.

The function of an air compressor is to supply and maintain a consistent amount of compressed air. Tools such as nail guns, paint sprayers, impact wrenches, air ratchets, air hammers, and grease guns use compressed air on a daily basis. Heating and cooling systems also use compressed air in ducting work. Blowing dust and debris from work surfaces is another common use for compressed air.

There are two basic mechanisms for which an air compressor works. An air compressor can be a reciprocating or a rotary (helical). A helical compressor can also be a scroll design. Within these mechanisms, the motor-driven pumps are further divided. For example, a piston and cylinder cast the reciprocating compressor, and an array of circular chambers makes up the rotary compressors. This is how a rotary compressor differs from a roll in design.)

Types of air compressors based on pressure:

• Low pressure:

  LP air compressors have a pressure range of up to 10 bar and are suitable for applications like inflating tires, small tools, and spraying.

• Medium pressure:

  MP compressors work well for nail guns, paint sprayers, and airbrushes. Their pressure range is between 10 to 15 bar.

• High pressure:

  High-pressure air compressors have a pressure range of 15 to 30 bar. They are suitable for applications like scuba diving filling stations, carbonated beverage systems, and gas stations.

Another common way to categorize air compressors is by dividing them into two main categories: positive displacement compressors, which include rotary and reciprocating compressors, and dynamic compressors, which rely on high-speed motors. While positive displacement compressors force air into a smaller space, dynamic compressors rely on centrifugal force and pressure.

Regardless of the kind of compressor used, the need for tanks is constant. The auto air compressor with a tank stores the compressed air and releases it at a steady rate.

Specifications and maintenance of an auto 20 bar air compressor

Specifications

The specifications for a 20-bar AC are as follows:

• Maximum Pressure: The maximum pressure of the AC determines the highest pressure the air AC can achieve. In this case, the air AC can achieve a maximum pressure of 20 bars. This is equal to 2,900 PSI. Such ACs are suitable for applications requiring higher pressure levels, such as inflating tires and spray painting.
• Horsepower System: Horsepower (HP) refers to the power output of the air compressor. 20-bar ACs can either have a two-horsepower rating or a higher rating. Higher horsepower ratings are suitable for more demanding tasks.
• Tank Size: The tank of an air compressor stores compressed air. The tank also determines the overall size and weight of the AC. Auto 20-bar air compressors have the following tank sizes: 6L(1.6 Gallon) to 24L (6.4 Gallon) or no tank at all. Smaller tank sizes are usually more mobile. Larger tanks provide a higher supply of compressed air.
• Voltage: The voltage rating of the air compressor determines the amount of power it provides. An auto air compressor runs on a 12V battery. In some cases, the AC can also use a 110-to-220V battery, which is equivalent to standard household electricity.
• Decibels: The decibel (dB) rating refers to the noise level of an auto air compressor. A smaller auto air compressor can make noise levels between 60 and 90 dB. Higher-dB levels are annoying and can affect work and health. dB levels higher than 100 can be fatal to human health.

Others include:

• Cut-On/Cut-Off Pressure: This refers to the pressure at which the compressor motor turns on and off. For a 20-bar air compressor, the typical cut-on/off pressure is between 6-8 bar (870-1160 PSI).
• Maximum Flow Rate: It refers to the measured cubic feet per minute (CFM) that the AC can achieve at a pressure of 20 bars. Higher maximum flow rates push more volumes of air.

Maintenance

With proper maintenance, an air compressor can operate for many years without breaking down. Below are some air compressor maintenance tips:

• Check for any signs of damages or air leaks. Repair any leaks or damages before using the AC.
• Dust and dirt builds up on the AC over time. Cleaning the compressor helps maintain its maximum performance. Use a vacuum or blower to remove dust and debris from the compressor.
• Replace the air filter regularly. The air filter prevents dust and debris from clogging the internal parts of the tool. A clean filter allows for smooth airflow.
