Vacuum Filter

About Vacuum Filter

 What is a Vacuum Filter?

A Vacuum Filter is a high-efficiency continuous filtration system that uses a vacuum (suction) to pull liquid through a filter media. It is ideal for fine particle filtration, particularly in grinding operations, where superior coolant clarity is required.

CONSTRUCTION & WORKING

 Main Components:

• Dirty Liquid Inlet Tank
• Vacuum Chamber (negative pressure zone)
• Filter Media Conveyor (paper/cloth)
• Clean Tank with Coolant Pump
• Vacuum Pump
• Float Switches & Sensors

Working Principle:

• Coolant with chips enters the dirty tank.
• It is drawn through the filter media into the clean tank under vacuum pressure.
• Solids stay on the media, clean fluid passes through.
• Clogged media triggers auto-indexing mechanism (media roll moves forward).
• Spent media is collected in a waste bin.

TECHNICAL SPECIFICATIONS (Typical Ranges)

APPLICATIONS

• CNC grinding machines
• Surface/cylindrical/centerless grinders
