Working:
Dirty fluid is fed under pressure in to inlet manifold. It is distributed equally in 4 different plates. Filter papers clamped & supported between plates separate the dirt & form a layer (cake). This effects finer filtration. The same filter with pre-coating can add further to fineness of filtration.
Applications:
Suitable as centralized fine coolant filtration for finish grinding, filtration of high viscosity grinding fluids & filtration of honing oil with pre-coat arrangement.
Features:
Very large filtration area is accommodated relatively small dimensions. The unit shown is having 10 m2 filtration area.
Totally automatic pneumatically actuated operation.
Dirt is purged with compressed air to recover fluid.
Low initial & operational costs.

The rotary vacuum drum filter (RVDF) is one of the oldest filters applied to industrial liquid filtration. A rotary drum filter resembles a large drum on its side. Half of the drum is submerged in the slurry, with the other half above it. The filter cloth winds around the drum and as the drum rotates, the slurry is sucked into the cloth. As the drum rotates out of the slurry, the cake is dried. This drying is caused by the vacuum continuously being drawn through the cake in the exposed section of the drum. At the end of the rotation cycle, at approximately a three o'clock position, the filter cake will be discharged and the process repeats itself. The filters may incorporate a drum cloth that is caulked onto the drum itself, or they may utilize an endless belt which tracks off and discharges away from the drum.
Typical Applications:
- Kaolin clay
- Titanium dioxide
- Alumina (red mud)
- Pharmaceuticals
- Chemical Processing
- Food processing (starches)

BONO ARTES developed a innovative solution that matches gravity filtration with self-cleaning operation. The result is a very simple unit with high filtration efficiency and low installation costs that is particularly suitable for cooling water filtration where very large capacities are concerned.
Filtration of raw water is operated by gravity. The operating principle is the hydrostatic level of the water up to the sand layer. The unit is provided with three chambers: one contains the filtration media, one filtered water and another is used for the separation between the filling media and the clarified water storage. Filtered water here contained is used to backwash the filter when the pressure drop reaches the set-point value. Unlike pressure-operated filters requiring pumps and blowers, backwashing is done by gravity and no rotating machinery, spare parts and control equipment (automatic valves, flow-meter, regulating instruments, control panels etc.) are required . Moreover the filter is operated without any supervising personnel.
The benefits of such applications lay in the efficient filtration process, very low operating costs and the advantage of being able to treat large flows of water.

Suction filters up to 18.5 gpm, Tank top mounting, ES 074/ES 094
Application
To be installed in the suction line of the pumps of hydraulic systems resp. upstream of the charge pumps of hydrostatic drives.
Performance features
Protection against wear: By means of filter elements that, in full-flow
filtration, meet even the highest demands regarding cleanliness classes.
Protection against malfunction:
By means of full-flow filtration in the system return, the pumps, above all, are protected from dirt particles remaining in the system after assembly and repairs, which are generated by wear or enter the system from outside.
Special features
Filter element locking valve:
Foot valve:
Ensures that dirt accumulated in the filter element is removed along with the element and cannot return to the tank. When the screw-on cap is removed for maintenance, the foot valve closes automatically. This makes it possible to service the filter even if it is submerged below the oil level in a full tank.
Filter elements
Flow direction from center to outside.The star-shaped pleating of the filter
material results in:
- large filter surfaces
- low pressure drop
- high dirt-holding capacities
- long service life
In filters with a magnetic system, the ferromagnetic particles in the fluid first pass through a strong magnetic field and are separated.
Filter maintenance
By using a clogging indicator the correct moment for maintenance is stated and guarantees the optimum utilization of the filter life.
Materials
Screw-on cap: Filter head: Filter bowl: Seals: Filter media:
Polyester, GF reinforced
Aluminium alloy
Steel
NBR (Viton on request)
EXAPOR®-inorganic microfibre web
Paper-cellulose web, impregnated with resin
Accessories
Electrical and optical clogging indicators are available. Dimensions and technical data see catalog sheet 60.20.

Polytech's conventional vacuum filters provide reliable automatic filtration of water based machine tool coolants and are suitable for coarse or fine solid contaminants and coolant flow rates from 20 to over 600 gallons per minute. Conventional vacuum filters utilize the difference in pressure between the dirty coolant tank at atmospheric pressure and the lower pressure created by the centrifugal pump's suction characteristics to force coolant through a non-woven filter fabric. The filter pump supplies clean, filtered coolant to service. These systems use a robust sludge conveyor to transport spent filter media and solid contaminants from the filter while a clean coolant reservoir provides a means of supplying coolant while the filter media indexes so that there is no interruption in coolant supply to the machine tool(s).
Conventional vacuum filters can typically provide 5 PSI differential pressure across the filter media so that coolant flow rates and contaminant loading per square foot far exceeds the capability of gravity type filters. The non-pressurized design is more reliable than pressure filters that require complex media handling and sealing arrangements. The automatic, unattended operation is much easier and less labor intensive than cartridge or bag filters that require manual filter changes.

Installed upstream of the pump or accessible from the outside in a particularly service-friendly configuration with a contamination indicator integrated in the suction line, suction filters protect the pump from large-particle contamination. A selection of elements adapted for use with the system protect installations and pumps in the range from 10 %u2013 25 µm with our micro-quality products, or in the coarse particle range using easy-to-clean wire gauze.

Vacuum Filtration
Vacuum suction is used to remove small contaminants from the spent coolant. A vacuum pump draws contaminated coolant through the filter screen. As the filter continues to run, it builds up a thick residue on its surface, known as filter cake, which traps even smaller contaminants and keeps them from migrating thorugh the filter screen.
