Vacuum roll is a nonwoven roll reinforced sucking and washing oil, water and other solutions by combination with a vacuum equipment.

FEATURES

• Speed-Up Production Line
  Capillary phenomenon effected by nonwoven fabric and reinforced suction by a vacuum equipment enable to decrease quantity of excess oil and speed up the production line.
• Improving Cleaning Power
  By drastically decreasing excess oil, quantity of washing oil can be increased to improve cleaning power furthermore.
• Adjustable Quantity of Excess Oil on the plate
  Controlling the vacuum equipment by the inverter enable to adjust vacuuming power, and control quantity of excess oil on the plate.
