Kaishan’s oil free screw air Equipment has precision host produced manufacturing process and technology has high volume ratio, low noise and heat generation, long service life, and noise as low as A) It can be placed next to the gas point to reduce the installation cost. High temperature resistance, normal operation at 55 ℃, convenient installation, low maintenance cost, high quality consumables, long service life, and easy replacement
Energy saving: more than 15% energy saving compared with dry oil-free engine
Environmental protection: no lubricating oil is used to avoid environmental pollution
Reliable: absolute oil free guarantee
As the purified water participates in the sealing, cooling and lubrication in the compression process, the efficiency is greatly improved. The gas production at the same specific power is more than 15% higher than that of the dry oil-free engine, which greatly reduces the energy consumption. Its consumables are only cheap water, air filter element and water filter element, and the maintenance cost is extremely low.
In the process of food and beverage processing, drug manufacturing, packaging, electronic manufacturing, painting, powder coating and textile manufacturing, any risk of oil pollution must be eliminated, otherwise it will lead to serious consequences, damage, production stoppage, brand and credit damage. Simeon oil-free screw Equipment uses pure water as the lubricating medium, and the main engine has no lubricating oil at all. Because of the cleaning effect of pure water on the air, the compressed air produced is absolutely pure, without any pollution.
