High Efficiency Replace for Hitachi 50HP New Style Air Oil Separator 59031060 52303020 52303021 52303330.The oil mist filter for vacuum pump is my company independent research and development production of high efficiency filtration product, used for oil lubricated rotary vane vacuum pump exhaust the oil and gas separation device, installed in the vent pipe of the vacuum pump, in the process of vacuum pump operation, exhaust gas go through the filter, oil mist particles in liquid form cannot directly go through glass fiber filter paper, and then attached to the filter paper, clean gas is under certain pressure go through the glass fiber paper discharge smoothly, and to reduce pollution,ensure a clean environment. Data: Brand model size of interface sucking rate Nanfeng KF25 DN25 8L/S Product features: 1, Vacuum pump oil mist filter shell adopt imported high strength transparent material production, high temperature resistance, corrosion resistance, good appearance, and can directly observe the oil and gas separation condition; 2, Long service life, effectively filtering mechanical pump vent discharge of oil mist, filtration rate above 99%, can effectively reduce the air pollution, improve the working environment; 3, Filter material adopt imported glass fiber paper, stable performance and strong oil absorption; 4, The device is designed as a quick release v band clamp flange, quick installation and easily fitting with vacuum pumps exhaust pipe of different models and import brands . Replacement steps of exhaust filter: 1.After the vacuum pump stops, ensure that the system is under pressure. 2.Remove the quick release v band clamp flange on the filter. 3.Remove the oil mist filter and replace it with a new one. Note: when replacing the oil mist filter, it is better to replace the vacuum pump oil at the same time.
