Zero leakage fans are a type of special fluid conveying equipment designed specifically for the requirements of "no medium leakage and no outside air infiltration". The core achieves "zero escape and zero cross-contamination" during gas conveying by optimizing the sealing structure and adopting isolated transmission or medium barrier technology. They are suitable for industrial scenarios with extremely high requirements for medium sealing. The core design logic is to address the leakage issues caused by the wear of seals and pressure imbalance in conventional fans, ensuring that the conveyed medium (such as toxic and harmful gases, flammable and explosive gases, precious process gases, clean gases, etc.) is completely confined within the flow channel, while preventing external impurities from entering and affecting process purity or posing safety risks.

Core design features: Upgraded sealing structure: Abandoning traditional packing seals and ordinary mechanical seals, advanced sealing forms such as dry gas seals, magnetic seals, and double-end face mechanical seals (with buffer liquid circulation systems) are adopted. Through the design of "medium isolation + pressure compensation", leakage channels are blocked. Some models are equipped with a sealing monitoring system to monitor the sealing status in real time and ensure the continuous and stable sealing performance.

The high-efficiency Centrifugal Fans of Shanghai Jipu Fan Equipment Co., Ltd. have formed a differentiated competitive edge in the industry by virtue of their technological and product advantages.

The DREM series centrifugal fans feature a direct drive structure for their motors. The DREK series centrifugal fans are directly driven by couplings. Their core advantages are primarily reflected in high energy efficiency and low loss. Introducing German blade design technology, a single diameter series covers 55 blade shapes, and the fan efficiency can reach over 90%, far exceeding the industry average. Combined with the streamlined volute design, it effectively reduces airflow resistance and can significantly reduce energy consumption costs in the long term.

Secondly, there is adaptability and durability: The products cover multiple fields such as industry, construction, and environmental protection. Special working condition models such as high-temperature and anti-corrosion can be customized. Key components are made of high-strength materials and have undergone dynamic balance tests. They have low operating vibration and noise, and their service life is more than 30% longer than that of conventional fans.

It has both service and response advantages: Relying on the abundant inventory of the base in Zhenjiang, Jiangsu Province, the order delivery cycle has been shortened to 60% of the industry average, and one-stop selection and installation guidance services are provided. Coupled with a standardized parts system, the later maintenance is convenient and efficient.

These advantages make its centrifugal fans suitable not only for specific scenarios such as automotive laboratories and tobacco processing, but also for the stable air supply requirements of large-scale industrial projects, making it a cost-effective choice in the field of ventilation equipment.
