A Trident Air Prime, Manual Control is a pump primer system that uses compressed air to prime a fire pump. It is a manual system, meaning that the operator must manually activate the primer.
To use a Trident Air Prime, Manual Control, the operator must first depress the push button on the control panel. This will open an internal valve to the water pump, allowing air to flow from the primer to the pump. The operator must then hold the push button down until the discharge pressure gauge begins to rise, indicating that the pump is primed. Once the pump is primed, the operator can release the push button.
The Trident Air Prime, Manual Control system can be used to prime a fire pump from a variety of sources, including the vehicle’s braking system or a properly regulated high pressure air cylinder. It is a reliable and effective system for priming fire pumps in a variety of conditions.
