What is the term used for an oil-less primer?

• A. Electric primer
• B. Hydraulic primer
• C. Air primer
• D. Manual primer

Answer: (C)

The term used for an oil-less primer is air primer. An air primer operates by utilizing compressed air to create a vacuum, which allows for the rapid drawing of water into the pump. This method eliminates the need for oil, making it suitable for various applications, especially where oil contamination could be a concern. In terms of its functionality, the air primer is advantageous for achieving efficient priming quickly without the risk of introducing oil into the system, which could affect the fluid being pumped or the environment. It is particularly effective in situations requiring clean operation, such as firefighting or other emergency services. Electric primers, hydraulic primers, and manual primers all involve different mechanisms that may incorporate oils or lubricants or rely on physical effort or power sources other than air compression for operation, which is why they do not fit the definition of an oil-less primer.
