It is designed to be easily installed in various vehicles, from industrial equipment to marine vessels and heavy-duty trucks. The separator box features a durable, corrosion-resistant stainless steel housing, ensuring it can withstand harsh environmental conditions and prolonged use.
The primary function of the GTB681 is to separate water and other contaminants from diesel fuel. This is achieved through a combination of gravity and centrifugal force, which causes the water and other impurities to collect at the bottom of the tank, while the clean fuel rises to the top and exits the tank through a filter element. The filter element, a Racor replacement for part number 9002, is highly effective at removing even the smallest particles and water droplets, ensuring that only clean, high-quality fuel reaches your engine.
The GTB681 is equipped with a 2.5-micron filter element, providing exceptional filtration efficiency. The filter element is easy to replace, ensuring that you can maintain optimal performance of your separator box. The box also features a clear sight glass, allowing you to easily monitor the condition of the filter element and the accumulation of water and contaminants.
The GTB681 comes with a drain valve and drain hose, making it simple to drain the accumulated water and contaminants from the tank. The drain valve is equipped with a valve cover to prevent debris from entering the tank when it's drained.
In conclusion, the Griffin GTB681 Diesel Fuel/Water Separator Box is a reliable and efficient solution for protecting your diesel engine from water and other contaminants. Its compact size, corrosion-resistant stainless steel housing, and high-quality filter element make it an excellent choice for various applications. Regular maintenance and replacement of the filter element are essential to ensure the longevity and performance of your separator box.
