Primarily used for secondary pressurization of compressed air in factories, to address issues of unstable pressure in robotic vacuum suction cups that cause failure to hold products and product detachment. This product ensures a stable supply of air volume and consistent supply pressure, improving product retrieval rates, significantly enhancing production efficiency, and reducing equipment failure rates and maintenance time. The equipment features a lubrication-free design, meets explosion-proof requirements, and utilizes oil-free compression technology, ensuring gas remains uncontaminated. It does not require electrical equipment, eliminating the risk of sparks. The output pressure can be infinitely adjusted. The driving air flow can be regulated, allowing control over the pressurization frequency, management of the output flow of pressurized gas, and extension of the service life of the pressurization system. It is self-cooling and does not require a cooler. It offers advantages such as compact size, lightweight, simple operation and maintenance, and easy repair.
