Types of On Board Air Compressors
On board air compressors come in a variety of types, each with its own advantages and disadvantages. The most common types include:
- Rotary Screw Compressors: These compressors are known for their high efficiency and reliability, making them a popular choice for heavy-duty applications. They use a pair of rotating screws to compress air, which creates a smooth and continuous airflow.
- Reciprocating Compressors: Reciprocating compressors are simpler and less expensive than rotary screw compressors, making them a good option for light-duty applications. They use a piston to compress air, which can create a pulsating airflow.
- Scroll Compressors: Scroll compressors are similar to rotary screw compressors, but they use a pair of spiral-shaped scrolls to compress air. They are known for their quiet operation and high efficiency, making them a good choice for residential and light-duty applications.
Factors to Consider When Choosing an On Board Air Compressor
When choosing an on board air compressor, it is important to consider a number of factors, including:
- Airflow: The airflow rate is measured in cubic feet per minute (CFM) and determines how much air the compressor can deliver. Higher CFM ratings are generally better, but the specific CFM requirements will depend on the intended application.
- Pressure: The pressure rating of an on board air compressor is measured in pounds per square inch (PSI) and determines the maximum pressure that the compressor can generate. Higher PSI ratings are generally better for applications that require high pressure, such as inflating tires or using air tools.
- Tank Size: The tank size determines how much compressed air the compressor can store. Larger tanks can provide a longer run time before the compressor needs to refill.
Maintenance and Care of Your On Board Air Compressor
Proper maintenance is essential for keeping your on board air compressor running smoothly and efficiently. Here are some tips for maintaining your compressor:
- Check the oil level regularly: Most on board air compressors require oil to lubricate the moving parts. Make sure to check the oil level regularly and add oil as needed.
- Drain the condensate tank: Water vapor can condense in the air tank, which can lead to corrosion. Drain the condensate tank regularly to remove any accumulated water.
- Inspect the belts and hoses: Regularly inspect the belts and hoses for wear and tear. Replace any damaged or worn parts immediately.
Best On Board Air Compressors Buying Guide: Choosing the Right Tool for the Job
An on-board air compressor is a valuable asset for anyone who regularly needs compressed air for tasks like inflating tires, operating air tools, or cleaning. From off-road enthusiasts to professionals working on construction sites, these portable powerhouses offer convenience and efficiency. However, navigating the diverse world of on-board air compressors can be overwhelming. To help you find the perfect unit for your needs, we’ve compiled this comprehensive buying guide.
1. Tank Size and Capacity:
The tank size of an on-board air compressor dictates how much compressed air it can store. Larger tanks mean longer run times and more air available for demanding tasks. For casual use, a tank size of 1-2 gallons might suffice. But if you frequently use air tools or plan to run them for extended periods, consider a larger tank, such as 3-5 gallons or more.
The compressor’s capacity, measured in cubic feet per minute (CFM), indicates how much air it can produce per minute. Higher CFM ratings allow for faster inflation and tool operation, especially for high-demand tools like spray guns or impact wrenches.
2. Compressor Type:
On-board air compressors are primarily categorized into two types: diaphragm and piston. Diaphragm compressors are lightweight, compact, and generally quieter. They are well-suited for smaller applications like inflating tires or light-duty tasks. Piston compressors, on the other hand, are more powerful and durable, making them ideal for demanding applications with higher air consumption.
Choosing the right type boils down to your specific needs. If you prioritize portability and quiet operation, a diaphragm compressor may be the best choice. But if you require high power and long-lasting durability, a piston compressor is the better option.
3. Pressure and PSI Rating:
The pressure rating of an on-board air compressor determines the maximum pressure it can generate. PSI stands for “pounds per square inch,” and higher PSI ratings mean greater force for applications like driving nails or operating air tools.
For basic inflation and light-duty tasks, a PSI rating of 100-150 PSI is usually sufficient. But if you need to operate demanding air tools or work with high-pressure applications, you’ll need a compressor with a higher PSI rating, typically 175 PSI or more.
4. Horsepower (HP):
Horsepower (HP) is a measure of an air compressor’s power output. Higher HP ratings generally translate to faster filling times and increased air output. This is particularly important for compressors with larger tanks or those intended for demanding applications.
Consider the tasks you will be performing and the tools you plan to use. For light-duty tasks like tire inflation, a 1-2 HP compressor might suffice. However, if you need to power heavy-duty tools or operate a large tank, a 3-5 HP compressor or higher may be necessary.
5. Duty Cycle and Operating Time:
Duty cycle refers to the amount of time an on-board air compressor can operate continuously before needing to cool down. It’s expressed as a percentage, with a higher duty cycle indicating greater continuous run time.
A high duty cycle is essential if you plan to use the compressor frequently or for prolonged periods. For demanding applications like construction or industrial use, look for compressors with a duty cycle of 50% or higher. However, for less intensive tasks, a lower duty cycle might be adequate.
6. Features and Accessories:
Modern on-board air compressors often come with a variety of features and accessories that enhance functionality and convenience. Some common features include:
- Automatic pressure switch: Automatically shuts off the compressor when the desired pressure is reached.
- Pressure gauge: Monitors the air pressure inside the tank.
- Regulator: Controls the output pressure for specific applications.
- Quick-connect couplers: Enable easy attachment and detachment of air tools and accessories.
- Integrated air filter: Removes impurities from the compressed air.
Consider the features that are most important to you and choose a compressor that offers those.
7. Noise Level:
Noise can be a significant concern, especially when using an air compressor in residential areas or sensitive environments. While all compressors produce some noise, some are quieter than others.
Diaphragm compressors are generally quieter than piston compressors, but quieter options are available in both types. Consider the environment where you will be using the compressor and choose one that meets your noise tolerance. Check the manufacturer’s specifications for noise level ratings.
Choosing the best on board air compressors for your needs requires a careful evaluation of your specific requirements and preferences. By considering the factors outlined in this guide, you can make an informed decision that ensures you get the right tool for the job and a rewarding experience.
