We are engaged in researching and manufacturing solid & liquid separation machines and components. Our mainly products are: TC series ceramic disc vacuum filter, DU series rubber belt vacuum filter, HVPF vertical press filter, LXD series continuous dumping centrifuge, PBF series continuous horizontal vacuum belt filter, DZY and DY series belt press filter, precise candle filter, ceramic plate, filtration fabric and belt, and soft-start and so on, which of them are widely used in mining, metallurgy, chemical industry, powder plant, food, environment protection and so on, which covers the 70% share of the Chinese filter market, meanwhile our products export to more than 20 countries. The unique production line of professional ceramic plate and rubber belt on the world was built up in our factory in 2005.

Now we are the largest manufacturer and supplier of the filter in China, of which the output of vacuum filters is the first of the world.

Our company passed the ISO9001-2000 International Quality Management System certification in 2001;

We become the Standard Drafter of the National filtration Machine Standardization in 2003. Now the National precise ceramic vacuum filter and large-size rubber belt filter, ceramic plate and rubber belt four kinds standards are drafted by our company; Meanwhile we are the pointed filter supplier of FGD industry in national electrical industry;

We got the "CE" certification on 2010. Our enterprise technical center was risen as the grade of Shandong province, and only our company win these strength in Chinese filter industry;

Products & Services

TC series precise ceramic vacuum filter is a new model high-effect, energy conservation filtration equipment, which is gathering electric-mechanical technology and the capillary effect, depending on the vacuum suction to come true the separation of liquid and solid. That's why this filter has very low power consume than traditional disc filters. Due to high efficiency of the new effect, especially the ceramic plates, this filter is welcome used in mining, metallurgy, chemical industry, environmental protection and so on.

PBF Series Horizontal Sway Pan Filter combine horizontal sway pan with the cloth to form vacuum chamber, which can accomplish the solid and liquid separation, cake washing, cake discharge and cloth washing functions together in one. This kind of filter is widely used in food industry, mining, chemical industry, environment protection industry and so on.

We have two kinds of belt press filter, one is DZY (DY) Series Belt Press Filter, and another is HVPF Series Vertical Press Filter.

DZY series belt press filter combines the pressure between the rollers with vacuum suction accomplish the solid and liquid separation.

HVPF series vertical press filter combines pump pressure, the gravity of the material and air, water pressure together form different pressure between both sides of the cloth, to separate the solid and liquid in high efficiency.

DZY series belt press filter is mainly used in waste water treatment industry, but HVPF series vertical press filter is widely used in mining, chemical, food, coal and waste water treatment industry and so on.

DU Series Rubber Belt Vacuum Filter is a kind of high efficiency automatic new-type filter. It adopts fixed vacuum chamber and the rubber belt moves on the chamber. It accomplishes the continuous filtration, cake cleaning, residue unloading and cloth cleaning and regeneration etc. It has been used in chemical industry, coal chemical, metallurgy, mines, flue gas desulfurization, food industry etc.

We are the candle filter manufacturer pioneer in China, now we have different kinds of candle filters, which of the filter media include e-PTFE candle tube, PE pipe, ceramic pipe, SS pipe. The precision of this media is from micron to nanometer. These filter is used in waste water treatment, food industry, Chemical industry water treatments, the clear filtrate can be back in system again.

Now we are the largest vacuum filter manufacturer in Asia, in NITX Group we can manufacture not only the filter frame, but also the filter media and automatic control system, for the filter media, we have ceramic products, such as plate and tube; the filter cloth and rubber filter belt.

Now for the ceramic plate, we have patent on the manufacture technology, which the strength and filter efficiency is much higher than other company.

Meanwhile for the cloth, we have cooperated with Finland Company to build the filter cloth co., in China. All of these are in order to supply the best service to the customer in time.
