When it comes to my 21 gallon Central Pneumatic air compressor, finding the right parts is crucial for its performance and longevity. After researching and testing various parts, I have put together this buying guide to help others in their search for 21 gallon Central Pneumatic air compressor parts.

Understanding Your Air Compressor Parts

Before diving into the buying process, it is important to have a basic understanding of the different parts of your air compressor. This will help you identify which specific part you need and ensure compatibility with your 21 gallon Central Pneumatic model.

  • Air Tank: This is where compressed air is stored and typically has a capacity of 21 gallons for this model.
  • Air Pump/Compressor Pump: Responsible for compressing air and sending it into the tank.
  • Motor: Powers the pump to generate compressed air.
  • Pressure Switch: Controls when the motor turns on and off based on the desired pressure level.
  • Gauges: Display the current pressure level in both PSI (pounds per square inch) and bar units.

Finding Reliable Suppliers

The first step in purchasing any part for your air compressor is finding reputable suppliers. It is important to purchase from trusted sources to ensure that you are getting quality parts that will not compromise the performance or safety of your 21 gallon Central Pneumatic compressor. Here are some reliable suppliers that I have personally used:

  • Harbor Freight Tools: This is where I purchased my 21 gallon Central Pneumatic air compressor, so naturally, they are my go-to for replacement parts. They have a wide selection of original manufacturer’s parts available online or in-store at affordable prices.
  • eReplacementParts.com: This website specializes in replacement parts for various tools, including air compressors. They offer a wide variety of brands and models, making it easy to find specific parts for your 21 gallon Central Pneumatic compressor.

  • Fittings/Connections: Make sure that the fittings are properly sized and compatible with your compressor’s specifications. Leaks around fittings can greatly impact the efficiency of your air compressor.
  • Gauges/Accuracy:Gauges should be accurate within a reasonable range (usually within +/- 5%). It is also important to check if they have an anti-vibration feature, as excess vibration can cause inaccurate readings over time.

Purchasing replacement parts can add up quickly, so it’s important to have a budget in mind before starting your search. While it may be tempting to opt for cheaper options, keep in mind that sacrificing quality can end up costing more in the long run if you have to frequently replace those cheaper parts. I recommend setting aside a budget specifically for high-quality replacement parts to ensure optimal performance and safety of your 21 gallon Central Pneumatic air compressor.
