MODEL ZJA DOUBLE-STAGE VACUUM OIL FILTER
This product is applicable to purifying transformer oil of above
500KV or below 750KV transformers as well as purifying insulation
oils of various electric apparatus.
MAIN FEATURES AND MERITS
International updated Oil Film Tension Osmosis Process” technique
is used so that water, gas and impurities can be effectively
High/low oil level automatic protection, automatic foam-removing,
high-effective needle foam-extinction are available. The article is
of automation, automatic constant temperature maintaining and easy
The machine has four filter stages for mechanical magnetic
filtering. The highest fineness reaches to 1m and cleanness of oil
purified reaches to NAS 1638 class 4.
Vacuum system consists of spinning vacuum pump and Roots Vacuum
Pump. Automatic circulation of filter unit of vacuum pump and
effective heat-exchanger make vacuum system work more reliably.
Most advanced Model TYB high-lift oil pumps are used as
inlet/outlet pumps, So,low noise is ensured.
Environmental protection Product of Sichuan Province.
Constant Qualified product.
Quality Product recommended by the national power ministry.
