BN series: Inline continuous deaerators



This deaerator allows you to easily and continuously remove air bubbles without a pressure-reduction device.
Air bubbles and dissolved gas can be removed from low- to high-viscosity liquids.

Features

Kurabo Inline Continuous Deaerator continuously removes air bubbles using centrifugal action of high-speed rotation instead of using a pressure-reduction device.
Since this system requires no stock tank and can be connected to the coating line or the production line, it requires a minimal installation space.

  • Inline continuous defoaming
  • Requires no pressure-reduction device and involves no evaporation of volatile components such as fragrance and solvent ingredients.
  • Enables defoaming in a high-viscosity solution.
  • Enables defoaming in a short time.
  • Allows you to easily perform operations without requiring any troublesome set-up.
  • Enables defoaming of only the required quantity only when necessary.
  • Requires no stock tank, thus saving space.

Main intended uses

Chemical, resin, adhesive, emulsified liquid, paint, ink
Sealing materials, polymers, cosmetics and food, etc.
