Buying Guide
Choosing the right air horn compressor depends on a few key factors. Here’s what to consider:
- Air Pressure (PSI): Higher PSI means a louder and more powerful horn. Check the recommended PSI for your air horn.
- Air Volume (CFM): Higher CFM means the compressor can fill the air tank faster, allowing for longer blasts.
- Tank Size: A larger tank means you can blast the horn for longer periods without the compressor having to constantly run.
- Portability: If you need to move the compressor around, consider a portable model with a carry handle or bag.
- Durability: If you’ll be using the compressor in harsh conditions, choose a rugged model built to withstand the elements.
- Power Source: Most compressors run on 12V DC power, but some require 110V AC. Make sure the compressor is compatible with your vehicle’s electrical system.
- Budget: Air horn compressors range in price from under $50 to several hundred dollars. Set a budget and stick to it.
FAQs
Q: What size compressor do I need for an air horn?
A: It depends on the size and type of air horn. Check the horn’s specifications for recommended PSI and CFM. A good starting point is a compressor that can deliver at least 100 PSI and 1 CFM.
Q: Can I use a tire inflator to power an air horn?
A: Some tire inflators can be used for small air horns, but they may not provide enough pressure or volume for larger horns. A dedicated air compressor is usually a better option.
Q: How do I install an air horn compressor?
A: Installation varies depending on the compressor and air horn. Follow the manufacturer’s instructions carefully. Generally, you’ll need to mount the compressor, connect it to a power source, and run an air line to the horn.
Q: Are air horns legal?
A: Laws regarding air horns vary by location. Check your local regulations before installing and using an air horn.
Q: How loud are train horns?
A: Train horns can be extremely loud, often exceeding 150 decibels. This can cause hearing damage, so use them responsibly.
