Model ID: DY195
The DY195 Venturi Effect Vapor Recovery Nozzle is a masterclass in passive environmental engineering. While many Stage II vapor recovery systems require expensive, high-maintenance external vacuum pumps to pull fumes back into the storage tank, the DY195 utilizes the fundamental laws of fluid dynamics to achieve the same result. By incorporating a precision-engineered Venturi chamber within the nozzle body, the flow of liquid fuel creates a localized area of low pressure. [Image showing the Venturi principle: fluid velocity increasing through a constricted neck to create suction] This naturally occurring vacuum is used to "inhale" volatile organic compounds (VOCs) directly from the vehicle’s fill pipe, returning them to the underground tank through a dedicated vapor return line.
This "Pump-Free" recovery method makes the DY195 the most cost-effective and reliable solution for gas stations looking to meet strict environmental emission standards without overhauling their existing infrastructure. Because it relies on the physical flow of fuel rather than an electric motor, the suction is always perfectly proportional to the fueling speed, ensuring optimal recovery efficiency at all times. The DY195 also features a liquid-sensing safety shut-off, which instantly closes the vapor path if any liquid fuel enters the return line, preventing "spill-back" or contamination of the vapor system. Built with Feiya’s signature durability, the DY195 is the ideal choice for high-volume stations that require a simple, robust, and environmentally compliant fueling solution.
