Compressed air tanks, also known as air receiver tanks, are an essential component of an air compressor system. They store compressed air and serve as a buffer to smooth out fluctuations in air pressure and flow. They also help to reduce the wear on the air compressor by allowing the compressor to run in cycles rather than constantly running.
Key Functions of Compressed Air Tanks:
1. Pressure Stabilization: The air receiver smooths the flow of air by acting as a reservoir to buffer pressure drops. This ensures a more consistent supply of air when the compressor is not running.
2. Storing Compressed Air: The tank allows the system to store compressed air for later use, which is especially important when there are fluctuations in air demand.
3. Reducing Compressor Cycling: By storing compressed air, the air tank reduces the frequency with which the compressor turns on and off, leading to increased lifespan and energy efficiency.
4. Cool Down of Compressed Air: Air compressor tanks also help in cooling down the compressed air before it reaches tools and equipment, reducing the chance of damage due to high temperatures.
Types of Air Tanks:
1. Horizontal Air Tanks:
o Mounted horizontally, these tanks have a wider footprint but are stable and suitable for systems that require a larger storage capacity.
2. Vertical Air Tanks:
o These are space-efficient tanks mounted upright and take up less floor space. They’re ideal for situations where storage space is limited.
3. Modular Tanks:
o Used in larger systems, these tanks can be connected together to scale up storage capacity as needed.
4. Stationary vs. Portable:
o Stationary Tanks: Fixed in place, these are typically used in industrial settings.
o Portable Tanks: Small, portable tanks are used with smaller compressors for home or mobile use.
Key Specifications:
When selecting an air tank for your compressor, consider the following specifications:
1. Capacity (Gallons or Liters):
o The size of the tank determines how much air it can store. A larger capacity is useful for high-demand applications.
2. Pressure Rating:
o Air tanks are rated for maximum pressure, commonly 125 PSI or higher. Make sure the tank is rated for the maximum pressure your compressor can generate.
3. Material:
o Most air tanks are made of steel, though some may be made from aluminum or composite materials, depending on the application. Steel tanks are durable but can rust if exposed to moisture, while aluminum tanks are lighter and resistant to rust but can be more expensive.
4. Drainage Valve:
o Moisture builds up inside the tank from the compression process, so a drainage valve is crucial for keeping the tank free of water and preventing corrosion.
5. Inlet and Outlet Ports:
o These are used to connect the tank to the compressor and air lines. The tank may have one or more ports, depending on the design.
6. Safety Valve:
o A safety valve is a critical component that ensures the tank doesn’t exceed its pressure rating. This valve will release pressure if it becomes too high.
Choosing the Right Air Tank Size:
• Compressor Size: For example, a small 1-3 HP compressor will generally need a smaller air receiver, while larger industrial compressors (5 HP and above) may require much larger tanks.
• Air Consumption: If you’re using air tools that require a lot of air (like sanders or spray guns), a larger tank is beneficial.
• Duty Cycle: High-duty cycle applications may require a larger air tank to handle the consistent air demand.
Example Sizes:
• Small Tank (2-10 Gallons): For small, portable compressors or home use.
• Medium Tank (20-30 Gallons): Suitable for light to moderate use in small workshops or garages.
• Large Tank (60+ Gallons): For industrial or heavy-duty use.
Maintenance Tips:
• Drain Regularly: Always drain the tank of accumulated moisture to prevent rust and damage.
• Check Safety Valves: Make sure that the safety valve is functioning properly.
• Inspect for Rust or Damage: Regularly inspect the tank for signs of wear, corrosion, or leaks.
• Check Air Pressure: Make sure the air tank operates within the safe pressure range as indicated by the manufacturer.
