About Compact Band Filter

What is a Compact Band Filter?

A Compact Band Filter is an automatic gravity-type coolant filtration unit designed to filter fine and coarse particles from liquids like cutting fluids, grinding coolants, and other process fluids. It uses filter media (filter paper) that automatically advances as it clogs, ensuring uninterrupted filtration.

CONSTRUCTION & WORKING

Main Components:

Inlet Chamber: Receives dirty coolant.
Filter Bed: Supports the filter media roll.
Filter Media (Paper Roll): The disposable paper removes contaminants.
Clean Tank: Stores filtered coolant.
Float Switch / Level Controller: Senses clogging and triggers media advancement.
Drive Motor / Gear Mechanism: Moves the filter media forward when clogged.

Working Principle:

Dirty coolant enters the inlet.
Coolant passes through filter paper solid particles are retained.
Clean coolant is collected below and reused.
When the filter paper gets clogged, the float switch activates the motor.
Used media is rolled up, and fresh paper is unrolled.
