Selfclean 6.46 Fuel Oil Filter
The Task
The economic operation of small and medium-sized diesel engines and generators with heavy fuel oil over a long period makes increased demands on the cleaning of lubricating oil. The quality of filtration of the lubricating oil is one of the factors determining its useful life, smooth engine operation and hence also the level of operating costs.
The Concept
The Boll concept separates filtration from lubricating oil care. The Boll selfclean type 6.46 automatic filter fulfills the task of lubricating oil filtration in the best possible way. It can be fitted directly to the engine as a main flow filter. Another solution is to incorporate it in the plant`s pipe system, possibly with additional flushing oil treatment. A double filter fitted directly onto the engine takes over the function of an indicator filter. In both cases, the Boll selfclean type 6.46 keep all solids away from the bearings. Removal of combustion residues from the lubricating oil, on the other hand, it is carried out by a separator or another auxiliary flow treatment section. This solution has proved to be advantageous both with regard to operational safety and from the point of view of economy.
The Solution
The Boll selfclean type 6.46 automatic filter`s superiority is demonstrated not only by a perfect filtration result, but also by the best possible operating behavior. Its high- precision construction is convincingly simple and robust. The selfclean 6.46, which can be mounted horizontally or vertically as an attachment or plug in filter, has a housing made from grey cast iron. The filter is available in various sizes with nominal diameters up to 150 mm and can be easily adapted to engine manufacturers` special requirements.
The Advantages
Bollfilters consistently remove dirt particles from contaminated liquid and recycle cleaned liquid back into the process. They help to ensure the plant`s operational safety continuously over a long period. This saves resources, protects the environment and reduces costs. Bollfilters are the best insurance for the product and the process. Boll automatic filters` special advantages include:
- precisely defined filter grades
- large filter surfaces
- low flushing quantities
- low pressure losses
- long service lives
- precise function of the back-flushing device
- compact, modular construction
- simple handling
- low maintenance costs
- long life
- low operating costs
SELFCLEAN 6.60/ 6.61
The Task
The trouble-free operation of all internal combustion engines or machining plants requires consistently good plant conditions, for which the cleanliness of the fuels, lubricants or cutting oils and coolants is essential. A constant operating pressure is also important. To achieve the necessary purity of these liquids, and guarantee constant pressure ratios, efficient automatic filters are required. These filters must
- have the capacity to handle high rates of flow and remain compact and ergonomic in design
- minimize back-flush discharge volumes to minimize waste
- guarantee a defined degree of cleanliness of the liquids
- achieve a high level of filter surface regeneration by efficient, dynamic self-cleaning
- prevent any drop in system pressure during the backflushing process
- protect moving parts from wear, increasing the useful life of the plant, and
- help to keep operating costs low by using durable components
The Concept
The Boll automatic filter selfclean type 6.60/6.61 is designed precisely to fulfill the task. The filter housing is equipped with several filter chambers. Each filter chamber contains a filter insert made-up of a number of filter candles, each candle is made from a spiral-wound support structure over which high-grade filter mesh is drawn. Large filter surfaces with high ``free passage`` areas guarantee a low pressure differential. As each filter chamber becomes dirt-loaded, it is isolated from flow and regenerated by back-flushing, each in sequence with no interruption to operation.
The Solution
During the filtration operation the liquid to be filtered enters through the inlet into the change-over housing, on which the filter chambers with the filter candles are mounted. The rotary selector mechanism is located in the centre of the housing. The contaminated liquid is fed into the filter chambers and flows through the filter candles from outside to inside. The solids to be filtered out are retained on the filter mesh. Cleaned liquid passes through the inside of the candle to the filter outlet in the lower section of the housing.
The Advantages
In economic terms, the best is always the result of ``as much as possible`` for ``as little as necessary``. Where the use of liquid fuels, lubricants and cutting oil and coolants is concerned, this means: consistent, precise filtration and regeneration of the liquid with minimal losses, a requirement for a forward-looking business. One-off investment in high quality filter systems becomes more cost-effective with increased service life and improved protection of machinery. In many cases it is possible to replace existing, outdated filters with the new Boll 6.60/6.61 model, with minimum disruption.
Advantages of the Boll automatic filters type 6.6O and 6.61 include the following:
- precisely defined filter fineness
- large filter surfaces
- minimal flushing quantities
- low pressure losses
- long service life
- precise function of back-flushing system
- compact, modular construction
- simple handling
- low maintenance costs
- long working life
- low operating costs
