The Racor RK20046-01 filter head is a high-performance fuel filtration solution designed for use in diesel engines, specifically those that operate under heavy loads or in harsh environments. This filter head is part of Racor's RK Series, which is known for its robust design and exceptional filtration capabilities.
The RK20046-01 filter head features a spin-on design, which makes it easy to install and maintain. The housing is made of durable cast aluminum, providing excellent heat dissipation and resistance to corrosion. The filter element is located within the housing and is pleated, providing a large surface area for maximum filtration.
The filter element itself is made of cellulose media, which is known for its ability to trap particles down to 2 microns in size. The filter element is also rated for a beta ratio of 1000, meaning that it can remove 99.9% of contaminants that are larger than 1 micron in size. This ensures that the fuel being delivered to the engine is clean and free of contaminants, which can help improve fuel economy, reduce emissions, and prolong engine life.
The Racor RK20046-01 filter head also includes a built-in water separator, which helps to remove water droplets that can form in the fuel system. The water separator is designed to allow the water to collect and drain out of the system, preventing it from entering the engine and causing damage.
The filter head also includes a bypass valve, which allows fuel to bypass the filter element when it becomes clogged. This ensures that fuel continues to flow to the engine even when the filter needs to be replaced. The bypass valve is adjustable, allowing users to set the pressure at which it engages.
Overall, the Racor RK20046-01 filter head is a high-quality, high-performance fuel filtration solution that is ideal for use in heavy-duty diesel engines. Its robust design, exceptional filtration capabilities, and built-in water separator make it an essential component for maintaining the health and longevity of diesel engines.
