Mayfran Central Coolant Filtration

PRESSURE MEDIA FILTER (DBF)

Proven reliable technology, the DBF is a highly efficient high flow coolant filtration system that is custom engineered and fully automatic.

The Pressure Media Filter (DBF) is a fixed chamber pressure filter capable of operating at high differential pressures to maximize filter cycle times, and can achieve clarity levels to 5 microns using standard filter media (both disposable and endless belt), and down to 1 micron using a filter aid (pre-coat).

Proven reliable technology, the DBF is a highly efficient high flow coolant filtration system that is custom engineered and fully automatic.

The DBF can be used for various processes and with various materials, removing fine particulates from metalworking fluids. With proper media selection, expect up to a 99% efficiency rating for applications including machining, grinding, drilling, honing, polishing, and washing.

The engineered DBF can use endless media belts, disposable media, or both to provide desired coolant clarity levels from 100 gallons per minute up to 10,000 gallons per minute.

E-SERIES VACUUM MEDIA FILTER

The VFE can be used for various processes and with various materials, removing fine particulates from metalworking fluids.
Chips and coolants are fed into the dirty tank together. The filter drum elements connected to a vacuum source are located in this dirty coolant tank. The dirty cooling lubricant is then sucked through the filter drum wall by the vacuum pump and pumped back to the machine tool. When penetrating the perforated drum walls, contaminations and fine chips form a filter cake. The regeneration process of the filter is triggerd by a time and vacuum switch. Here, only one drum segment is flushed with clean cooling lubricant before the drum is indexed by one cycle. As 98% of the filter surface is always being used under vacuum according to this principle, the coolant flow is not interrupted permanent flow) so that no clean tank is required. The flushed back filter cake is carried out by a scraper conveyor in the filter tank together with the chips.

RBF FILTER

To be used for machining and grinding of steel, gray cast iron, brass, copper and aluminium.
This filter is based on the build-up of a filter cake which is periodically removed through rotation. During the periodic rotation, the coarse particles deposited in the filter housing are also carried out by special cleats. Simultaneously, the accumulated filter cake is removed by the brush, and the filter mat pores are additionally cleaned using a separate clean coolant (flushing) pump from inside to outside. This lowers the coolant level and completes the cleaning cycle. The dimensions of the clean tank are matched to your local conditions.
