The small but mighty sprayhead is the unheralded work horse for most BUNN coffeemakers. The average coffee drinker probably is unaware of the importance of this component and its function in a quality brewer. It is the critical delivery vehicle that controls how the water gets dispersed, or "broadcast," over the coffee with the ultimate goal being uniform flavor extraction from a bed of grounds.
BUNN’s unique sprayhead designs create the right amount of turbulence to cause the grounds to rise and suspend in the hot water solution in order to extract flavor evenly and thoroughly from all of the grounds. Without a proper sprayhead design, water drips straight through and often does not expose coffee evenly. This will result in very erratic levels of extraction, often all in the same pot of coffee.
