About us

    Hangzhou Donghuang Pressure Filter Factory,Since the foundation of the enterprise in 1984, it keeps improving. The Pressure Filters can be sold in more than 20 cities in China. The products can be found every where in China except Tibet and Taiwan. The sales and production amount is increasing in Viet Nam, and Indonesia. In 2003, the total capital of the enterprise can be 19.60 million yuan. While pay much attention to the quality of the products, the factory highlights the improving of the service, which wins the acknowledgement of the customers.
The factory can produce all kinds of specifications of pressure filters( from IM2一$00M2) and it offers all kinds of polypropylene pressure filters as well as belt pressure filters, processing according to the requirement is available as polypropylene filters, filter frames. The customers can have all specifications of polypropylene frames with the original machine frames.
Strengthen polypropylene pressure filters can be widely used in foods, pharmaceutical, wax, petroleum, metallurgy for the separation of solid and liquid. The structure is simple and it is easy to operate. But some of the casting iron frame is heavy and it is hard to operate and it is easy to be corrosive. Some of the materials can be anti-corrosive as anti-corrosive steel frame, glass plates frame, rubber frame. The anti-corrosive steel frame is expensive, wood frame is easy to be deformed and other frames are not strong enough (the rubber frame will generate a kind of chemical element which can affect the quality of the media when it is used for a long time)
The strength polypropylene pressure filters produced by the factory is improved based on the original metal structure frame pressure filters. The metal frame is treated with anti-corrosive processing and the frame is made from the polypropylene materials pressed with the best method. The mechanical properties are great and the chemical properties are stable. It is anti=pressure, anti-high temperature and the permitted temperature can be within 110℃, even 120℃ in short period. The material is non-toxic, anti-corrosive, light and easy to operate and the surface is flat. The speed of the filtration is faster than other frames. The technology power is strong. It is the idealist equipments at present.
