Types of Compressors
When shopping for used compressors for sale, it's important to understand the different types available. Each type of compressor is designed for specific applications, so choosing the right one is crucial for optimal performance.
Reciprocating Compressors
Reciprocating compressors are commonly used in industrial and automotive applications. They work by using pistons to compress air, making them ideal for high-pressure tasks. These compressors are known for their durability and reliability.
Rotary Screw Compressors
Rotary screw compressors are popular for continuous use in industrial settings. They provide a steady flow of compressed air and are less prone to overheating compared to reciprocating compressors. This makes them a great choice for businesses that require constant air supply.
Centrifugal Compressors
Centrifugal compressors are typically used in large-scale operations. They use rotating impellers to compress air and are best suited for high-volume applications. These compressors are energy-efficient and require minimal maintenance.
Benefits of Buying Used Compressors
Purchasing used compressors for sale offers several advantages over buying new ones. Here are some of the key benefits:
- Cost Savings: Used compressors are significantly cheaper than new ones, allowing you to allocate your budget more efficiently.
- Proven Performance: Many used compressors have already been tested in real-world conditions, providing you with a better understanding of their capabilities.
- Environmental Impact: By buying used, you contribute to reducing waste and promoting sustainability.
Considerations Before Buying

Application Requirements
Determine the specific requirements of your application. Consider factors such as pressure, flow rate, and duty cycle to ensure the compressor meets your needs.
Condition of the Compressor
Inspect the condition of the compressor thoroughly. Look for signs of wear and tear, rust, or damage that may affect its performance. Request a detailed inspection report from the seller if possible.
Warranty and Support
Check if the compressor comes with any warranty or after-sales support. While warranties for used compressors may be limited, having some form of protection can provide peace of mind.
Where to Find Used Compressors for Sale
There are various platforms and sources where you can find used compressors for sale. Here are some of the most reliable options:
Online Marketplaces
Platforms like eBay, Craigslist, and specialized industrial equipment websites offer a wide selection of used compressors. These platforms allow you to compare prices and read reviews from other buyers.
Local Dealers
Local dealers often have a selection of used compressors that have been inspected and refurbished. Buying from a local dealer can provide you with the opportunity to inspect the compressor in person and ask questions directly.
Auction Sites
Auction sites such as GovDeals and Ritchie Bros. Auctioneers frequently list used compressors for sale. Participating in auctions can help you secure a compressor at a lower price, but it requires careful bidding strategies.
Inspect Before Purchase
Inspecting a used compressor before purchase is crucial to ensure its quality and reliability. Here are some key areas to focus on during your inspection:
Motor and Controls
Test the motor and control systems to ensure they function properly. Look for any signs of malfunction or irregularities in performance.
Air Intake and Filtration
Check the air intake and filtration system for cleanliness and efficiency. A clogged filter can reduce the compressor's performance and lead to premature wear.
Valves and Seals
Inspect the valves and seals for leaks or damage. Leaky valves can result in pressure loss and increased energy consumption.
Maintenance Tips for Used Compressors
Proper maintenance is essential for extending the lifespan of your used compressor. Follow these tips to keep your compressor in top condition:
- Regularly change the oil and air filters to maintain optimal performance.
- Inspect belts and pulleys for signs of wear and replace them as needed.
- Monitor pressure readings and adjust settings to prevent overloading the compressor.
