AirDog by PureFlow

---

PureFlow manufactures and supplies AirDog fuel air separation systems and Raptor lift pumps for stock and high-performance diesel pick-up trucks. The Air Dog Fuel Preporator high-output pump and filtration system is designed to remove water, particulates, and most importantly entrained air & vapor from diesel fuel. Help increase fuel economy and performance in your Ford Powerstroke, GM Duramax, or Dodge Ram diesel with an AirDog.

PureFlow manufactures and supplies AirDog Fuel Air Separation Systems and Raptor lift pumps for stock and high-performance diesel pick-up trucks. The AirDog lift pump is the only true air separation system on the diesel market today. They help increase fuel mileage, horsepower, and torque, and can extend the life of your expensive fuel injection system components.

With many different units to choose from, PureFlow has you covered. Raptor 4G fuel pumps offer increased performance with a budget in mind. The Raptor fuel pump combines performance and affordability. The 100 GPH is the perfect option for the user just looking for a replacement fuel pump and the 150 GPH version provides higher than stock flow rates to feed your modified engine with the steady flow and fuel pressure it needs.

The Original Air Dog, AirDog II-4G, and AirDog II-5G products remove all entrained air, water, and particulates down to 2 microns from your diesel fuel. The AirDog Fuel Preporator lift pump is the original Fuel Air Separation System. With the capability to provide fuel at flows and pressures beyond the maximum requirements of the engine. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or jam the gyrator fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump.

Next, the AirDog II-4G features many innovative improvements for increased pump performance, less noise, and less maintenance. The advanced 4G technology offers protection and performance like never before! The patented air separation, along with a water separator, and fuel filter makes sure your expensive injection system components get all the clean fuel they need. The II-4G also overcomes loss of power due to driving in higher altitudes. In addition, it improves engine performance by eliminating spray pattern disruption due to air entering the system. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases overall engine efficiency across the power and torque range. The 4g is available in either 100 or 165 GPH units.
