If you do not have a filter for the above mentioned, harmful substances will be able to pass freely, which will lead to performance reduction in air conditioning systems.

Inhalation of contaminated particles has negative consequences to the human body: allergic reactions, lung strain and respiratory tract irritation, unpleasant feeling caused by bad smells, lack of concentration, general weakness, etc.

By installing a cabin vehicle filter, all above mentioned adverse impacts will be removed, drivers and passengers would feel better and more comfortable and the air conditioning system in the vehicle will be protected.

We can easily conclude that, in the times when the world is fighting for a healthy environment, one of the important factors in this process is the cabin filter.

Our filters use optimal materials with a high degree of filtration so they are providing little resistance to airflow and cause a very small pressure drop in the air conditioner.

Our filters meet all of the air conditioners’ requirements (protection and facilitation), but above all, they protect the health of people in the cabin, and the journey is pleasant and comfortable.

Hydraulic oil contaminant in these systems is caused by abrasive particles, water, chemicals and other dirt from hydraulic systems and environment.

BOSFILTER hydraulic filters successfully protect against these impurities, preventing clogging of hydraulic valves and damage of vital components of the system.

Our development and research, testing and quality control provide high performance and quality of our hydraulic filters.

These filters are of compact structure with properly defined “by-pass” valves, high-quality corrosion protection and careful selection of high quality filtering materials.

Contemporary designed, superbly done and controlled according to European standards, our filters meet all requirements set by world leading hydraulics manufacturers.

These are hydraulic presses, hydraulic generators, hydraulic pumps, etc.

Dirty fuel can damage the gasoline high-pressure pump and valves and diesel engines jets.

A failure in the fuel system, due to the dirt that is already in the fuel or due to penetration of particles coming from the environment (dust, sand, organic compounds) and water, requires one of the most expensive engine repairs.

In addition to pump, valves and nozzles wear, unclean fuel causes lower engine performance, increased fuel consumption and environmental pollution.

BOSFILTER fuel filters are designed and manufactured according to the highest standards and strictest requirements (for the original part). High quality fuel filter is our imperative and it is achieved through:

• selection of the highest quality filter materials that are controlled in the laboratory and well processed in the filter production process, which provides conditions that allow only clean fuel to enter the engine
• optimal filter paper surface placed in a small volume
• great retention capacity and accumulation of dirt, pentane, paraffin and abrasives
• corrosion protection with optimal housing structures
• detailed craftsmanship and high quality seals for optimum sealing and quality in the toughest working conditions

In addition to the filter paper, another filter material that is used is felt or special cotton fibers.

Also, we have a wide range of fuel filters, which are made as complete filters or as inserts. The complete filter is a unit consisting of housing and insert.

Filter inserts can be rough or fine and can be used only once. They are installed in the fuel system according to the engine manufacturer’s instructions.

We also manufacture fuel filters for medium power engine systems and high-pressure pumps that fully meet the requirements of the renowned engine manufactures.

All fuel filters are tested in accordance with the terms defined by engine manufacturers and are certified in the laboratory.

Air filter inserts provide effective engine protection from damage caused by the presence of dust and other contaminants in the air.

Our air filter inserts are carefully designed and manufactured to meet the engine and industrial facilities manufacturer’s requirements, which are the ones that need filtered air.

BOSFILTER’s imperative is a high quality air filter achieved by:

• high efficiency purification, up to 99.9%
• selecting the highest quality filter paper which is controlled in the laboratory and is successfully processed during filter production
• corrosion protection for metal parts
• detailed craftsmanship and high quality seals for optimum quality and sealing

These prerequisites make our air filters well accepted by the consumers and they recognized as a guaranty for:

• long and reliable life
• full functionality
• compliance with engine manufacturers regulations, as well as with international standards in the air filtration field

Heavy-duty air filter inserts are made as a two-stage (primary and secondary).

Primary implant acts as the main filter, while the secondary is a security filter, thereby insuring adequate motor protection in extreme operating environment.

We also manufacture the so-called dry air filters. These filters consist of a housing with connections, inserts or primary and secondary implant sets, a dirt indicator and a dust vacuum container.

BOSFILTER also produces air filters with oil bath, which are intended for use in medium and heavy working conditions. The filters are usually made of two-part housing, where the lower part of the chassis houses oil and the upper one the inset.

Filtering material of the insert is usually a wire cloth, PVC or natural fiber which provides air purification efficiency of 99.5%.

In addition to our standard production program, we have developed an air Ram fitter program, filter plates, filter bags and sleeves for industrial filtration and dust collection. For the purposes of high efficiency air filtering in electrical, food and pharmaceutical industries, we have developed a series of absolute filters.

In addition to its primary function – lubrication, oil is also used for cooling, corrosion protection and cleansing. The following functions emphasize the importance of maintaining adequate levels of oil cleanliness in a system.

BOSFILTER oil filters are designed to ensure the highest possible engine protection against abrasiveness and other contaminants and provide oil’s full functionality.

Our imperative is a high quality oil filter that we achieve with:

• highest quality filter paper selection in well-treated filter production process
• optimal surface filtration with minimal resistance to fluid flow
• high level of dirt accumulation
• casings resistant to high pressure and protected against corrosion
• impeccable performance of the by-pass valve at cold engine start, in situations when the filter is dirty or under extreme operating conditions
• proper functioning of the check valve, which prevents filter discharge when the engine is switched off
• detailed craftsmanship and high quality seals for optimum sealing and quality in the toughest working conditions

We also have a wide range of oil filters and oil filter inserts that are used on most types of petrol and diesel engines to filter the engine oil and transmission fluid. Each filter is designed and constructed in a way which meets or exceeds the requirements which are defined by the leading engine manufacturers.

BOSFILTER also produces a large number of different types of oil filters for heavy mining and construction equipment.
These filters are designed based on the latest findings in the field of filtration and allow proper machine operation in conditions of extreme loads.

Available technology and production, as well as the specific process requirements enable us to repair different kinds of filters, as well as special construction filters or filters that can rarely be seen in everyday practice.

We have a large number of specific filtering materials, as well as the types of adhesives for the filter industry, so we can make an adequate substitute.

Reparation is being done when a customer is in need of a filter in a short time period, because in order to create a new filter, it is sometimes necessary to create new tools, master new technologies, and thus the filter price can be drastically increased.

By repairing a filter or by replacing filter material, we can save from 20% – 40%, and the derived-repaired filter is fully operable.

Also, by repairing the filter and saving the material, we can significantly influence the environment preservation and raise the ecological awareness of our satisfied customers.

The filter paper made by „Hollinggsworth & Vose and Neenah Gessner“, as well as the entire semi-finished products which we use, have been attested by the manufacturer, and together with our professional staff, guarantee the excellent quality of all the filters which come out of our production line.

BOSFILTER produces air filters for all types of internal combustion engines in cars, buses, trucks, locomotives, ships, agricultural and construction machinery etc.

We also have air conditioning filters for all the motor machines mentioned above. Also, we produce hydraulic filters for cars, as well as industrial machines which are widely used. Our offer includes filters for special purposes and the ones made according to customized requests (cabin coating for electronic dust painting). In the future, we plan to offer the EKO filters as well.

Our annual production capacity is of 1.5 million filters, with the technology accommodating mid and small production series, and which also has the possibility of quick program change needed for the wide spectrum of filters. We are devoted to producing best quality filters, together with the best service offered at a reasonable price to our clients.

Air filters have a significant influence on fuel consumption and this is why they should be timely changed. It is recommended that the air, fuel and oil filters should be replaced every 10,000 kilometers. Having in mind that our roads are full of dust and dirt, the timely replacement of the air filter is of great importance.

Oil filters are of big importance when it comes to the life of the engine, and in particular attention should be paid and the filter should be replaced when switching from synthetic to mineral oil and vice versa.

Replacement for all types of filters should be done by qualified personnel, because of the technical, as well as the ecological aspects. Drivers who change filters on their own often do not leave them in the places reserved for recycling, and filters end up in backyards and rivers. It is known that one liter of oil pollutes about a million gallons of water in rivers.

Because fuel filters are used to remove impurities from the fuel and facilitate the proper functioning of the engine and contribute to consumption savings, it is necessary to replace them on time. Engines in cars may stop working because of irregular filter changing.

The air conditioning system should be cleaned and checked for bacteria that may have accumulated in the last season before the heat period starts, and before the air conditioning is used in vehicles every day. It is also good to replace the filter in the heating and cooling system of the vehicle cabin, which is often mistakenly misunderstood as being the same as the air conditioning filter.

Air enters the air conditioner through the cabin filter, whereas the air conditioner has no filter whatsoever. Maintenance is also very important and drivers should not do it on their own, they should hire a professional. Freon must also be checked, air conditioning cleaned from any bacteria, and that cannot be done by the driver.
