Types of Direct Driven Air Compressors

A direct driven air compressor is a type of air compressor where the motor and pump are directly coupled. While direct driven compressors come in various forms, they can generally be divided into types based on two key criteria: the mechanism used to compress air and the power source used to drive the compressor.

• Compression Mechanism:

Within a direct-driven compressor, the mechanisms used to compress air can vary between models. Two common types are the piston (also known as reciprocal) and screw direct drive air compressor.

• Piston Direct Driven Air Compressors:

  Piston direct driven air compressors are models where the compressor pump uses a piston to compress air. The piston moves back and forth within a cylinder, drawing in and compressing air. These models are quite common and are often used in small to medium-sized compressors. Their smaller size makes them useful for portable compressor models. Piston compressors can be further divided into two types based on their design: single-stage and two-stage.

  Single-stage compressors are models where the air is compressed in a single cylinder. They are most suitable for applications that do not require a high-pressure output. On the other hand, two-stage piston direct driven air compressors compress air in two cylinders. They have a higher efficiency and deliver compressed air at higher pressures. This makes them more suitable for industrial applications.

• Screw Direct Driven Air Compressors:

  Screw direct driven air compressors use a rotary mechanism to compress air. Two rotors within the compressor housing rotate in opposite directions, squeezing and pushing air into the storage tank. This moves it with a warm compression process. This abstracts the air pressure internally. Direct driven rotary screw compressors are very efficient, especially at higher pressures. They are most commonly used in industrial settings where high volumes of compressed air are required continuously.

Another way to categorize direct driven air compressors is based on their source of power.

• Electric Direct Driven Air Compressors:

  Electric driven direct air compressors are models that use electricity to power the motor that drives the pump. They are the most common type of air compressor found in homes and workshops.

  The motor within an electric direct drive air compressor is usually integrated into a single unit with the pump. This makes for easier installation and a shorter overall length within the compressor. Electric direct driven air compressors are quiet and emit no fumes. However, users must ensure that their power supply provides enough voltage to run the motor smoothly.

• Gas Direct Driven Air Compressors:

  Gas driven direct air compressors are models powered by gasoline engines. This gives them the ability to compress air without needing to be plugged into an electric outlet. Gas compressors are suitable for outdoor use in remote locations where electricity is unavailable. Their design is basically similar to electric direct driven compressors in that the motor is directly coupled to the pump. Gas compressors tend to be larger and heavier due to the weight of the engines and fuel tanks.

Specifications and Maintenance

Industrial air compressors are serious machines built for serious jobs. That's why bearing-driven air compressors have familiar and direct-driven simple specifications. Knowing some key specs helps buyers understand their work ability and needs better.

• Compressor Power: This shows how much direct-driven power the compressor produces. It usually appears in simple horsepower (HP). Each additional one in HP boosts the power and air volume a little more.
• Running HP: Direct-driven air compressors have a running horsepower rating too. This is how much horsepower the motor uses while running. A motor needs a certain amount of horsepower to run efficiently. Smaller compressors run at 3/4 HP, while larger ones can reach 5 HP.
• Motor Type: Motors that drive the compressor directly are normally permanent split capacitor (PSC) or totally enclosed fan-cooled (TEFC) motors. PSC motors are less expensive and often found in smaller PSC models. Larger motors use TEFC to protect from dust and heat better. Motors rotate at typical speeds of 1,725 revolutions per minute (RPM) or 3,450 RPM. Higher RPM means more compressed air volume. 1,725 RPM is normal for pistons, while TE motors use 3,450 for less friction and more efficiency
• Operating Pressure: This is the pressure at which the compressor works best. It has to be the same as what tools and jobs need. The working pressure is given in pounds per square inch (PSI). Common working ranges are 90 to 150 PSI. Simple hand tools like nailers work great at 90 PSI. Bigger tools like spray guns and sanders may need up to 150 PSI. Knowing the pressure tools need helps pick a compressor with enough pressure.
• Pump and Tank Size: Direct-driven compressors have pump sizes from small 1-gallon hot dog tanks to bigger 60-gallon vertical tanks. Vertical tanks take up less floor space. Selecting a compressor with more tank size means storing more air to run tools longer.
• Management of Filter: To work properly, it is essential to clean or replace the air compressor intake filter. The filter stops dust and dirt from entering the compressor. A blocked filter can reduce airflow and performance.
• Condensate Drain: Moisture builds up inside the air compressor while it runs. It is necessary to drain water out regularly. Water left in can cause rust and damage over time. Draining is generally done through a tap at the bottom of the compressor tank.

Usage scenarios for direct driven air compressors

How to choose a direct driven air compressor

Direct-drive air compressors are popular and generally suitable for business buyers on a budget because of their lower initial cost. However, plenty of other things need consideration when selecting an air compressor for business use.

• Nature of the business

  The tools and equipment which need compressed air to function are likely to differ depending on the industry. Assess the air tools used in the particular trade. Pay attention to the required CFM and PSI to pick a machine that can adequately energize the tools. Consider the number of tools and compressed air needed as well. A machine used in an auto repair shop that regularly services cars will need to be more powerful than one used in a woodworking shop that mostly uses manual tools.

• Operating environment

  The environment the air compressor will be working in is another important thing to think about. Consider whether the space the compressor will be in has sufficient ventilation to safely and comfortably use a direct-driven air compressor. Ventilation is essential because the motor can overheat during prolonged operation, and the machine will generate heat. A suitable way to cool down belt-driven compressors is to use more belts but allow the motor to run more loosely so it can do less running.

• Initial purchase and operating costs

  The direct drive model generally has lower initial purchase and operating costs because it is more energy efficient. Consider the cost of replacing the air compressor if it needs to be replaced earlier than the life expectancy. The typical life expectancy of a direct-drive compressor is about 5 to 7 years compared to a belt one, which may last for 10 to 15 years or more.

• Noise from the motor

  Direct-driven models have noisy motors, which some people may find disturbing. Although they are generally more affordable, they may not be the best choice if protecting against noise is essential. Belt-driven models are quieter but cost more.

• Portability

  Direct drive air compressors are usually small and light enough to carry if portability is important. Consider what size and weight a portable compressor will be before buying one.
