AirDog® II-4G Fuel Air Separation System featuring Demand Flow Technology and Enhanced Features

AirDog® II-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the fuel pump.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog® II-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.

Sharp knives, but some defects
The knives cut well and are generally functional. However, I had some issues with the overall quality. The handle doesn’t feel secure when holding it and arrived slightly peeled, which raises concerns about durability. Additionally, the largest knife arrived with a slightly bent tip, which was disappointing. They work, but the quality control and packaging could definitely be improved. For these reasons, I can’t give a higher rating.

Good quality
Color: White, Color: White
5 Stars - Excellent Quality and Performance! I couldn't be happier with this knife set! Each knife is incredibly sharp right out of the box and cuts through everything with ease—whether it's vegetables, meat, or bread. The handles are comfortable to hold and well-balanced, making food prep a breeze. The design is sleek and looks great in my kitchen. I've used them daily for a few weeks now, and they’re still holding up perfectly. This set offers outstanding quality at a great price. Highly recommended for home cooks and pros alike!
