2 cylinder piston air compressor

Types of 2 cylinder piston air compressors

The 2 cylinder piston air compressor is the most common type in the air compressor category. It works by changing the volume of a space, thereby forcing more air into that space to develop pressure. The gas laws state that when the piston of an air compressor moves downward, the volume of a particular space increases. Once that happens, fresh air rushes into the chamber. When the piston moves upward, the volume decreases, and the air pressure increases.

Despite the popularity of 2-cylinder piston compressors, manufacturers have seen it fit to create variations to ensure specific needs are adequately taken care of. Here are some:

• By Design

  Separating air cylinders compressing more than one stage is a single 2 piston stage air compressor. An air compressor with a single 2-piston cylinder will usually heat up faster than compressors with two stages. This is because the cooling process is happening internally, thanks to the second cylinder. Therefore, it is best for applications that have a constant air requirement. On the other hand, dual 2-cylinder piston compressors have two cylinders. While they may be 2-piston compressors, they also have one stage or two compressing roles.

• Mounting

  Base-mounted air compressors typically sit on a horizontal or flat surface. They are usually used in business and industrial settings. This is because they have huge motors and tanks that supply a vast amount of compressed air. They also offer more accessibility when it comes to maintenance. A direct drive mounted compressor, on the other hand, has the motor attached to the compressor. This allows it to offer higher compression, and that is why it's common in small to medium-sized direct drives.

• Lubrication

  Compressors can be oil-filled or ooze-less. The oilless 2-piston air compressor works without lubrication. manufacturers mostly make them with NO lubrication requirements. Therefore, they are ideal for non-industrial uses. That said, two-piston oilless air compressors are more prone to wear and tear. Oil-based and oil-filled compressors use oil to reduce friction between moving parts. They provide longer lifespans and are more durable, thanks to the consistent lubrication. They are also better at withstanding harsh conditions. As a result, businesses are more likely to use oil-lifting compressors.

Specifications & maintenance of 2 cylinder piston air Compressors

Specifications

• Power

  The power of a two-cylinder air compressor is usually expressed in kilowatts (kW) or horsepower (HP). It represents the capacity of the machine to compress air. The HP of the air compressor can be from 5 HP to 15 HP or more, depending on the model and usage requirements.

• Working Pressure

  The working pressure of a two-cylinder air compressor is expressed in pounds per square inch (PSI). The working pressure determines how much pressure the machine can provide. Generally, the working pressure of a two-cylinder air compressor can reach up to 175 PSI or more.

• Airflow

  The flow rate of a two-cylinder air compressor is expressed in cubic feet per minute (CFM) and determines the speed at which the machine compresses air. Depending on the model and usage requirements, the flow rate of a two-cylinder air compressor can be from 15 CFM to 35 CFM or more.

• Storage tank

  The storage tank of a two-cylinder air compressor plays the role of storing compressed air. Its capacity is expressed in gallons (G) and determines the amount of compressed air that can be stored. The capacity of the storage tank can be 60G, 80G, 100G, etc., depending on the model and application requirements.

Maintenance

For users of two-cylinder air compressors, routine maintenance is crucial to ensuring the equipment's optimum performance and prolonging its service life. The following suggestions will assist users in efficiently maintaining their air compressors:

• Check the oil regularly: A two-cylinder air compressor is routinely checked to make sure it has the right amount of lubricating oil and the right quality. Replenish or replace the oil as instructed if the oil level is below the specified range or if it becomes unfit for use.
• Maintain cooling: The air compressor's refrigerating parts, such as the radiator, fans, etc., should be cleaned up on a regular basis to ensure adequate cooling effect. Avoid using the air compressor in high-temperature environments or for extended periods at a time to prevent damaging the internal parts from overheating.
• Replace wearing parts: Over time, components such as air compressor belts, filters, and valves may become worn out or damaged. It is important to replace them promptly to ensure the normal operation of the equipment.
• Pay attention to noise: A two-cylinder air compressor produces some noise under normal operating conditions. If the noise level significantly increases during the operation, it indicates that there may be parts of the equipment that are worn out or damaged. In this case, users should stop using them to avoid damage and have them checked and repaired as soon as possible.
• Keep it clean: Clean the outside surface of the air compressor machine regularly to avoid dust and dirt buildup. This not only improves the equipment's aesthetics but also helps with heat dissipation, lowering the risk of overheating and ensuring normal operation.
• Follow your operating manual: Each model has different maintenance requirements and methods. Users should refer to the operating manual and follow the instructions for maintenance and care.
• Regular professional maintenance: In addition to daily maintenance and care, users should also have their two-cylinder air compressors routinely checked and maintained by professionals to ensure that the equipment is in excellent condition and to avoid potential problems.

How to choose

Consider the following factors when selecting a 2-cylinder air compressor for a business.

• Evaluate power needs

  Determine the required power to run tools and equipment. Look at the horsepower and CFM rating. Make sure the air compressor provides sufficient power for all applications. Investing in an underpowered air compressor can disrupt workflows.

• Pick the right tank size

  Consider selecting a compressor with a large storage tank. A bigger tank reduces the frequency of the compressor running. It also provides a steady supply of compressed air. Choose a 60-gallon tank or larger for heavy-duty, continuous use.

• Think about noise levels

  Take into consideration the noise rating of the air compressor. Choose a model with a low decibel rating to keep the work environment comfortable. Air compressors tend to be loud, so consider options that will lessen the impact on workers. This might mean selecting a portable air compressor with insulation or rubber mounts to dampen vibrations or a two-stage compressor that is quieter during operation.

• Decide between portable and stationary

  Determine whether a portable air compressor works best for business needs or if a stationary model is a better fit. A stationary compressor is more suited to a workshop that requires compressed air at a constant high volume. Consider a portable model for external worksites or applications that need a flexible, movable solution.

• Simplicity of operation and maintenance

  Pick an air compressor that is simple to operate and maintain. Consider the design of the controls and the frequency of required maintenance tasks. Select a model with minimal maintenance requirements to save on long-term operational costs.
