Based on the Star GP design and built on innovations first developed in the Bell Infusion, the Star Infusion is the ultimate in forced air helmet technology. The Snell SAH2010 Star Infusion is the first model in the industry that can be used as either a side air forced air or top air forced air model. Sold in the top forced air configuration, the Star Infusion can easily be adapted for use as a side forced air helmet though an innovative kit system. The helmet can also be used in a non-forced air configuration. Developed with feedback from the world’s best NASCAR and Sports Car drivers, the SAH2010 Star Infusion is the helmet of choice for racers in a closed car environment using a forced air system. The Star Infusion features an ultra-lightweight carbon composite shell, high-tech aggressive aero styling and a pro-plus style interior that provides superior comfort. The pro-plus interior delivers a custom interior fit by combining Bell’s soft plush-density fit pad system, contoured cheek-grip pad system to reduce movement and integrated collar that is designed to fully support the driver’s lower jaw bone area. With the versatility of the Star Infusion, professional racers no longer have to choose between a side forced air or top forced air model. Sold in the top forced air configuration, the helmet can be transformed into a side (left) forced air helmet (side air kit sold separately). The Star Infusion incorporates Bell’s ground-breaking air chamber technology to increase pressure and accelerate airflow (when used with an external forced air system) to maximize airflow for improved ventilation and comfort. In the top forced air configuration, the Star Infusion divides the air inflow evenly in vent channels that direct ventilation to the front of the helmet to cool the face and prevent shield fogging and into the air chamber top pad, evenly dispersing airflow to cool the driver around the top of the head. The Star Infusion features the new Quick Lock forced air nozzle that locks the forced air connector in place yet allows for easy release. The smaller nozzle design helps accelerate airflow into the helmet. The Quick Lock nozzle can be used with traditional 1.5 inch diameter forced air hoses by using the following forced air adaptor that connects the hose with the Bell Quick Lock nozzle:
