The AT-Cleaner coolant filtration system offers advanced cleaning for water-soluble coolants using a proprietary hydraulic centrifugal separator that is media and maintenance-free. The media-free design offers for significant savings on consumables and downtime versus typical bag filters. The cleaner coolant, to 10-15 microns, increases coolant, pump, and tool life while improving part accuracy and finish.

DPF - THE COMPACT PAPER FILTER UNIT
As a deep-bed paper band filter from the MMF series, the DPF impresses with its compact design and a good price-performance ratio.

Its optimized design uses hydrostatic pressure to achieve efficient filtration of the cooling lubricant.

High filter fineness combined with low paper consumption make the DPF an intelligent solution for modern demands on cooling lubricant preparation.

• Good value for money
• Super compact design (40% less floor space, compared to most other paper filters with similar flow capacity)
• Suitable for all machining processes
• High filter fineness
• 100% side seal efficiency by special Tsubaki chains

MODE OF OPERATION
Contaminated cutting fluid enters the filter unit from the side into the inlet diverter.

In the filter housing, the coolant flows through the paper media into the clean tank, while swarf and other residues stay on the paper media.

Swarf and other residues build up and form a filter cake on the paper media and cause the fluid level in the filter to rise until a level sensor is actuated.

The scraper conveyor then removes contaminated paper, swarf and other residues into a collecting container

The High Pressure Bypass filter (HPBF) provides high pressure coolant to a machine tool and also continuous cleaning of the main coolant thanks to its bypass filter function.

FEATURES AND BENEFITS

• High-pressure coolant provides faster production, longer tool life and better surface quality
• The paper media continuously and economically removes dirt particles in bypass filtering mode, even when the high-pressure pump is not running
• The automatic operation of the paper filter minimizes production losses and costs from having to change any bag or magnetic filters
• Increased machine uptime through cleaner coolant, less sludge settling and reduced coolant tank maintenance
• Integrated sensors in both machine tool and HPBF tanks give a warning when the coolant level is low or high
• Easy installation for both existing and new machine tools

THE UNIVERSAL AND MULTI-VARIANT PAPER BAND FILTER
The HPF paper band filter from our MMF series is a proven standard in our filters. Its optimized design enables the filtration of cooling lubricants of all cutting processes with a high filter fineness. The operating principle of the deep bed filter is based on hydrostatic pressure, which acts on the liquid on the filter paper and thus allows increased throughput and improved filtration with less space and paper consumption. The HPF is easy to handle and offers the possibility of pre-depositing ferromagnetic chips, for example, by means of a magnetic pre-separator.

• High filter fineness
• Suitable for all machining processes and materials
• Compact design
• Low maintenance
• Perfectly customizable system (magnetic pre-separator, etc.)
• Efficient handling of light floating chips
• 100% side seal efficiency

MODE OF OPERATION
Contaminated cutting fluid enters from top of the filter into the inlet diverter.

Hydrostatic pressure forces the dirty coolant through the Filter Media and into the clean tank. With this, a filter cake will be formed on the paper media

Media Carrier Belt reliably removes contaminated filter paper from the unit into a collecting container.

The lift bottom centrifuge is designed for continuous operations. This up and down motion of the live bottom pushes the chips upward through the sieve. The centrifugal force, up to 500 times the force of gravity, will dry the chips, resulting in the maximum degree of de-oiling. The remaining oil content is extremely low. The dry chips fall down over the edge of the drum into a container. The are different models and different drives available.

The coolant filter for highest quality demands especially for grinding, honing and superfinishing applications. The modular design allows easy up- and downgrading and the candle filter with dry discharge is energy saving.

The safest way to prevent faults.

Coolant filter used for central coolant cleaning for several machine tools. The universal central filter for short swarf.

This filter is used for the filtration of coolant with high flow rates. Paper- or endless belts are available.

THE NEW GENERATION OF MEDIA-FREE FILTER UNITS
For customers where maximum availability and low maintenance requirements come first, we offer the RBF-E in our MMF series. The RBF-E is a self-cleaning filter without consumables.

Its rotating endless steel filter fabric not only makes changing the paper roll superfluous, but is also particularly insensitive to increased chips.

The compact design and efficient principle of hydrostatic pressure as the driving force of the filtration allow a sizing of the filter capacity from 100 l/min to 1500 l/min with a good filter fineness.

• Paper-free filter system
• Resistant construction
• Low maintenance
• Filter capacity of 100 to 1500 l/min possible
• Filter screen cleaning technology by both backwash and brush
• v2a filter fabric

MODE OF OPERATION
This filter is based on the build-up of a filter cake which is periodically moved through rotation.

The coarse particles are carried out by special cleats.

Simultaneously, the filter cake is removed by the brush and the filter screen pores are additionally cleaned using a separate clean coolant (flushing) pump from inside to outside.

More and more, strict environmental requirements oblige companies to process the swarf and dispose of them in a dry condition. The reclaimed coolant is to be fed back in to the production process. The VBU centrifuges are available in different dimension and are used for continuous operations

Mayfran drum filters have proven themselves many times over through their reliability, the flexible set-up possibilities and low operational costs for filtering the emulsion or coolant.

In most cases they do not need pre-separation of swarf and therefore are especially suitable for being included into the planning of the swarf disposal set-up as well as being retrofitted as an extension of the filtering capacity.
