HOFFMANN vacuum belt filters are used for cleaning emulsions and low-viscosity oils for machining steel, castings, aluminum and other nonferrous metals.

Method of Operation:

The coolant tank for the filter facility is made up of two chambers:

• the fouled tank section (bottom made of bolted, stainless slotted-screen elements), and the
• suction chamber (clean tank section) located below the fouled tank section

Advantages:

• easy installation
• high surface quality of the fabricated part being machined
• continuous supply to your machine tool with cleansed coolant without any down time. The suction pump transports around 10% more medium than required for filtration, ensuring that the clean tank section is also adequately filled during the cleaning phase.
• fully automatic operation
• high filtering capacity with small filter surface area thanks to high vacuum level
• stainless, removable slotted screen bottom
• low maintenance
• ideal for oily chips and accumulation of graphite
