Customer Questions & Answers

  • Question: What is the purpose of the Viair 93940 40 Amp Air Compressor Relay?

    Answer: The Viair 93940 relay is designed to control the electrical current to a 12-volt air compressor. It acts as a switch, allowing the compressor to start and stop based on the system's pressure needs. This ensures optimal performance and longevity of your air compressor by preventing overheating and providing a safe operation environment. If you're using an air suspension system or high-powered air tools, this relay is essential to manage the amps effectively.
  • Question: Is the Viair 93940 relay waterproof and durable?

    Answer: Yes, the Viair 93940 relay is built to withstand various environmental conditions. It features a robust design that helps resist moisture and debris, making it suitable for outdoor applications or in harsh conditions. This durability is crucial, especially for users who need reliable performance from their air compressors in rugged work environments. Whether you're off-roading or working at a construction site, the relay holds up under pressure.
  • Question: How do I install the Viair 93940 air compressor relay?

    Answer: Installing the Viair 93940 relay involves connecting the relay to the compressor and the power source according to the wiring diagram provided in the packaging. Typically, you will connect the input power to the relay's terminal, and output wires will go to the compressor. It's essential to use proper tools and follow best practices to ensure a secure connection. For instance, using heat-shrink tubing can enhance the connections' reliability and safety.
  • Question: Can the Viair 93940 relay be used for other applications?

    Answer: Yes, while the Viair 93940 relay is specifically designed for 12-volt air compressors, it can be used in various other automotive and industrial applications requiring relay control. This versatility allows it to power multiple devices that need high current, like electric fans or lights. Users with unique setups can benefit greatly from the relay's capability to manage higher amps safely in customized projects.
  • Question: What amp rating is suitable for my compressor when using the Viair 93940 relay?

    Answer: The Viair 93940 relay is rated for 40 amps, which is ideal for most 12-volt compressors. It's crucial to match the relay's amp rating with your compressor's specifications to ensure safe and effective operation. For instance, if your compressor draws 30 amps, the 40 amp relay provides an ample margin to avoid overload situations. Always double-check the compressor's manual for recommended relay specifications.
  • Question: Does the Viair 93940 relay have a built-in fuse?

    Answer: The Viair 93940 relay does not come with a built-in fuse. It's recommended to use an external fuse when installing the relay to provide an additional layer of protection against electrical surges. A fuse rated slightly higher than your compressor's draw ensures that you can handle short spikes without damaging your system. This precaution is especially vital if your application has varying electrical loads.
  • Question: Is the Viair 93940 relay suitable for high-performance compressors?

    Answer: Absolutely, the Viair 93940 relay is engineered for high-performance 12-volt compressors. It can effectively manage the power demands of high-output models, making it a top choice for those needing robust air supply for applications like air suspension setups or vehicle tire inflation. For users operating high-performance compressors, this relay helps maintain optimal function without drawing excessive current that might lead to system failures.
  • Question: Can I use the Viair 93940 relay with a standard automotive compressor?

    Answer: Yes, the Viair 93940 relay is compatible with standard automotive 12-volt air compressors. It is suitable for applications ranging from filling tires to powering pneumatic tools in automotive repair. For instance, if you commonly inflate tires during service work, this relay ensures that the compressor operates effectively without overheating, maintaining operational reliability during use.
  • Question: Where can I buy the Viair 93940 40 Amp Air Compressor Relay in Fiji?

    Answer: You can purchase the Viair 93940 40 Amp Air Compressor Relay at Ubuy in Fiji. Ubuy offers a convenient platform to find various automotive accessories, including reliable air compressor components. Their user-friendly interface allows easy navigation and selection, ensuring that you can find the relay you need quickly and efficiently.
  • Question: What is the difference between a relay and a switch for compressors?

    Answer: A relay and a switch may seem similar, but their functionalities differ, especially in high-current applications. A switch is a manual device that controls the power flow directly, while a relay operates as an automatic switch that can handle higher amps without manual intervention. The Viair 93940 relay is perfect for automating the compressor's operation based on system demands, making it more efficient for users who need continuous pressure without manual control.
