Robust and efficient filtration solutions for power generation applications (wind, thermal, nuclear or biogas) to optimize your processes, minimize equipment maintenance tasks and avoid safety risks
Protect your equipment
Today’s power generation industry cannot afford to stop the continuity of its service due to the growing demand for electricity.
Power generation systems, whether power plants, thermal power stations or renewable energy facilities, often use engines, turbines or other sophisticated mechanical equipment. This equipment is expensive and requires proper maintenance.
Air filtration prevents solid particles and contaminants from entering the systems, which can cause premature wear, corrosion and damage to components. By filtering the air, the life of the equipment is extended and maintenance and repair costs are reduced.

Diesel Engines
Diesel Engines
Diesel engines need protection from various aspects such as extreme temperatures or pollutants during the combustion process. The surrounding environment is also exposed to gases and must also be protected by proper filtration.
Internal combustion engines and all their components such as rings or pistons can become worn due to dust particles in the surrounding environment. This leads to costly maintenance repairs, which can be eliminated with the right filtration solutions. In addition, these particles also decrease process efficiency.
Another problem that can result from not having the right filtration system is the risk of overloading motors due to the extreme temperatures they are subjected to, among other things.
Our air inlet filtration solutions protect you from any risk of overloading, prolong the life of your engine, reduce CO2 emissions and maintain its original performance.
Gas Turbines and Engines
Gas turbines and engines
Gas turbines are electricity generators designed to operate in any area or region of the world, and even in extreme climatic conditions. Turbines must work properly in areas with polar cold, tropical areas, deserts, and even at high altitudes. Therefore, the filtration system used must match the conditions for optimal overall protection.
How does gas turbine filtration work?
Filtration in gas turbines is essential to avoid corrosion, engine wear, high load losses… At Venfilter, we offer you HEPA and molecular filtration solutions that will guarantee the good performance of your installations.
The air intake system to the compressor has the elements to ensure that the air coming from the environment enters the turbine in the most suitable conditions of cleanliness and with little turbulence. To do this, they have filters that are responsible for removing dirt that can drag the air and blade systems so that the air flow is as laminar as possible.
Common pollutants in gas turbines
The main factors that can make air the worst ally are, among other things, contaminants or particles of various sizes that it may contain. Damage to gas turbines can be divided into three main types:
– Mechanical damage
– Chemical damage
– Thermal damage
In applications such as offshore platforms, refineries… Turbines have to deal with pollutants such as salt that can create corrosion, heavy hydrocarbons or gases.
The importance of filtration in gas turbines
When it comes to power generation, costs must be as cost efficient as possible to cope with renewable energies in order to maintain profitability.
Air filtration is key to the role of energy efficiency. With our Venfilter Energy solutions adapted to the sector, you will protect your gas turbines by keeping the engines in perfect condition and prolonging their service life.
Nuclear Power Plants
Nuclear Power Plants
In all industries, filtration plays a fundamental role. But in the nuclear power industry in particular, it plays an even more important role because of all the risks involved. In fact, HEPA filtration systems were invented in the 1940s as part of a programme to remove radioactive particles. Air filtration is to be considered as a part of the safety plan of the whole nuclear power plant in these cases.
However, in this industry, the main focus is on achieving maximum levels of airtightness. The risk of contamination, both by aerosols and radiation, in nuclear power plants always exists.
Types of containment in nuclear power plants
- Static
This type of containment system acts by physically containing the risk of the plant. That is, through the design of the plant structure with doors, walls…
- Dynamic
This containment system is the one we work with at Venfilter, as it is based on relying on air filtration to stop contamination and guarantee that radioactive particles are filtered by the system and contained in a specific area of the plant.
Risks in the nuclear energy sector
When designing the filtration system in the nuclear sector, there is not only the risk of contamination and irradiation by pollutants such as hydrogen fluoride. The risk of explosion or fire, corrosion, condensation, seismic and climatic risks must also be taken into account.
Applications within the sector
We have developed our filtration solutions, taking into account the multitude of applications found in this area of “Energy and Cogeneration”. We provide you with filtration systems for:
- Fuel processing plants
- Storage centres or landfill sites
- Atomic energy research laboratories
- Radiotherapy departments in hospitals
| Non-radioactive air filtration system | Potentially radioactive air filtration system |
| These systems are based on the collection of air from outside. The importance here lies in the filtration in the air intake system. Therefore, the main pollutants will be external particles such as dust, pollen, etc…. Depending on the required parameters, outside conditions… The air intake system may also include a temperature treatment, to regulate the environment. | These filtration systems, as their name indicates, will try to contain radioactive particles. These systems will be located in the reactor building or in the containment building. In addition to the filtration required in non-radioactive air filtration systems, contaminants such as iodine must also be filtered out by molecular filtration. In these spaces, iodine is one of the main contaminants in nuclear power plants and can be found in gas or aerosol form. |
At Venfilter, we put our 30 years of experience in the filtration sector at your service, guaranteeing you with our equipment a dynamic containment with which you will protect people and also the environment from these particles and radioactive gases in any type of nuclear power generation facility.
Wind energy
Wind Energy
Wind turbines, whether onshore or offshore, have to cope with extreme conditions. Therefore, filtration must be highly efficient to ensure performance, prolong equipment life and minimise energy costs.
These wind turbines are installed in challenging locations where corrosive elements such as salt, water or moisture are present. Proper filtration will keep the nacelle, generator, tower and electrical equipment and substations clean.
Filtration needs of wind turbines
There are different parts in wind turbines and each one will have different needs. That is why Venfilter has developed specific filtration solutions for towers, nacelles and substations.
The tower of each wind turbine needs good air recirculation for the air conditioning process. Venfilter systems for these installations ensure clean air free of contaminants for the processes.
The nacelles of each wind turbine must have a correct filtration system to protect the most sensitive components to contamination such as the generator, the gearbox, the brake and the control electronics.
If any contaminants, such as dust, were to reach these controls there would be a high risk that they could overheat, resulting in costly damage. However, with the correct filtration system, the proper functioning of the installation is guaranteed.
Offshore or coastal wind farms have substations and they are essential to carry out the functions of the wind farm. They are responsible for connecting the energy generated in the turbines to the electricity grid. The substations must be protected from salt and humidity generated in the installation environments. Venfilter provides you with optimal filtration systems to guarantee correct ventilation and air filtration.
| Air filtration in onshore wind energy | Air filtration in offshore wind energy |
| Turbines installed on land are exposed to high levels of pollution from agricultural or terrestrial air pollution. In rural environments, the main pollutants are dust, pollen or other particles of agricultural origin. In industrial environments, the main pollutants will be smaller particles from hydrocarbons and other industrial pollution. Without proper filtration, this can lead to yield losses and even wind farm failures. | Wind turbines installed in offshore and coastal environments present a higher risk, as they are exposed to very harsh conditions. With 98% of the particles being smaller than 1 micron, filtration must be optimal to cope with their small size. The challenge of filtration lies in being able to filter out corrosive elements such as salt and moisture from the mist. In addition, the filtration system must be able to cope with high water loads. Without proper filtration, these contaminants can reach sensitive plant components, creating downtime, costly repairs and in some cases equipment failure. |
Generators
Generators
There are different types of power generators, but the main function of any power generator is to be a self-contained device capable of transforming mechanical energy into electrical energy.
Types of power generators
Depending on factors such as the amount of energy, the operating area, dimensions… these types of generators will be used:
- Gas generators
- Diesel generators
- Petrol generators
Why is filtration necessary for power generators?
Generators can be exposed to environmental elements such as water, salt or extreme temperatures. It is the ventilation unit that must provide adequate protection in order to optimise its service life and cost-effectiveness.
While it is clear that we must protect the machinery, we must also protect its environment from hazards such as the high level of noise generated. One solution is to add silencers at the air inlet and outlet to protect the devices.
A good maintenance of the generator through filtration will be key to maintain its functions of use. Above all, aspects that damage generators are the weather and the quality of fluids such as fuel.
At Venfilter, we have a wide range of air filtration products that adapt to both indoor and outdoor generators and optimise the operation of the machinery for the peace of mind of both operators and owners.
Compressors
Compressors
In many industrial processes, air compressors are essential to maintain efficient filtration over long periods. Compressed air is the fourth largest form of energy after water, gas and electricity.
In process industries such as agriculture or steel, compressors are used as air separation or insertion units and become a key component. They depend on optimal filtration to keep costs down and extend their service life.
Why is filtration necessary for energy compressors?
Each installation will have completely different environmental or operating conditions, such as temperature, humidity or airborne contaminants. In addition, the risk of overload and pressure drop must be taken into account to increase filtration efficiency.
The function of the compressor will be to generate compressed air flows. The latter can often be contaminated by dust, solid particles, oil particles… If not treated with the correct filtration system they can cause:
- Defective finished products
- Equipment wear and tear
- Increased maintenance costs
- Irruptions in the production process
- Pressure drop
- Contamination of the final product
At Venfilter, we have been working for more than 30 years in the filtration sector and we customise our solutions for you according to your needs, providing durability and reliability for your equipment and installations.
Improve the efficiency of your processes with proper air filtration.
Contaminated air can negatively affect the efficiency of the power generation process. For example, if the air used in combustion contains impurities such as dust, dirt or metal particles, it can affect combustion efficiency and reduce energy production. In addition, contaminants can clog ducts and heat exchange surfaces, decreasing energy transfer and affecting the overall efficiency of the plant.
By filtering the inlet air, a clean supply is ensured and the performance of the power generation process is optimised.
