As the vacuum pump of this type uses oil for keeping lubrication and vacuum of the rotating part, a stable and reliable vacuum can be obtained, and thus this product can be applied to various industries.
This product can be used in any environment because of air cooling, recycling of the lubricating oil, built-in oil dust filter for clean exhaust air, low noise and low vibration.
In addition, this product can be used for a long time as it is easy to maintain by applying a simplified handling method such as a simple structure and air cooling system. When oil change is required, you need not replace other consumables at the same time. Direct coupling drive using the flange type motor of international standard reduces power consumption and pump weight, and maintenance is very easy.
