Brief Introduction
TC precise ceramic vacuum filter combines mechanical and electric machine, ceramic tube with micro-hole and ultrasound to separate solid and liquid depending on vacuum suction and capillary function with high efficiency and energy-saving equipment; they are widely used for mine, metallurgy, chemical industry and environmental protection industry.

Characteristics:
High vacuum degree (0.090.098MPa), filter cake has low water content
Solid content of liquid <50ppm, repeated application is available, drainage is lessened.
It can save 90% energy or above in contrast with traditional filter with low consumption and low cost.
Filter cake cleaning process is added to clean proper materials.
It combines PLC, computer and automatic valve control with high automatization and labor force has been lowered.
Close structure, cover less floor area, convenient installation and maintenance
Advanced drainage system fits for any working state.
