How do I find the right filter for my paint system?

Selecting the right filter for your paint system is a crucial step to achieve optimal results and efficient performance. At NeuFilter, we offer you a range of individually adaptable solutions. One of them is our own development, the PaintBlock filter cube.

Here are a few steps and considerations that may help you choose:

System protection/filter class: Selecting the right filter system is crucial for protecting your system and the quality of the painting result. Filter classes vary in their ability to separate particles of different sizes. A suitable filter not only protects the quality of the paint but also the system components from wear and contamination. This can extend the life of the system and reduce maintenance costs.

By including filter class and system protection in your considerations, you can make an informed decision and choose the most suitable filter for your paint system.

Environmental emissions of exhaust air

  • Emission standards: When choosing the right filter, you should ensure that it meets applicable emission standards to minimize the environmental impact of exhaust air.
  • Air quality: A high-quality filter can help remove harmful particles and volatile organic compounds (VOCs) from exhaust air, resulting in improved air quality around your plant.

By including the environmental emissions of exhaust air in your selection criteria, you contribute to the sustainability and environmental compatibility of your paint plant.

Type of paint/Paint data sheet: Different painting processes and types of paint, as well as their characteristic features, require different types of filters. Factors such as solids content, water-based and solvent-based play a significant role in choosing the right paint separator.

Painting plant schematic/layout: The layout of your paint system can influence the selection of the filter. Some filters are better suited for compact designs, while others have been developed for large-scale systems.

Air flow: The way the air is routed through your system also influences the filter selection. Factors such as the relaxation area and the distance from the paint material to the paint separator play an important role in our selection.

flow rate: The airflow in your system is a decisive factor for the optimal filter selection. It influences the achievement of the ideal sinking rate and therefore has a direct influence on the quality of the painting result.

differential pressure: The pressure conditions in your system can influence the efficiency of the filter, so choose a filter that fits the pressure conditions of your system.

Custom-Made: Since all NeuFilter products are made to order, they can be individually adapted to the specific needs of your system.

modular systems: Some of our filter solutions are modular so that they can be easily adapted to changing conditions.

references: Ask about reference projects or case studies that had similar requirements so you can make an informed decision.

Inventory and target/actual analysis: An initial consultation is the fastest and best way to find the right filter. It is important for us to understand all filter stages as well as the entire painting plant and your process as a whole.

With our wide range of products, we will work together to find the right filter for your application and application. Because many plant parameters in paint deposition have an enormous influence on the absorption and separation capacity of filters.

What are the delivery times for filter cubes at NeuFilter?

At NeuFilter, we value short and reliable delivery times. Delivery times at NeuFilter may vary slightly, as most products are manufactured according to customer orders. This enables a high degree of adaptability to the specific needs of your system. You are welcome to discuss details of the delivery conditions directly with our sales department. The delivery times for our PaintBlock filter cube are usually 1-2 weeks.

How does the pressure difference between filter boxes affect my air balance and energy balance?

The pressure difference of a filter is an important factor that directly influences the air balance and energy balance of your system. A filter with a low pressure difference has several advantages:

  • More efficient air circulation: A filter cube with a low pressure difference allows more efficient air circulation through the system, resulting in better air quality.

  • Lower load on fans: Since the resistance of our filter boxes is lower, the fans have to work less to push air through the filter. This can extend the lifespan of the fans.

  • Energy saving: A filter cube with a low pressure difference requires less energy to filter the same amount of air. This results in a reduction in operating costs.

  • Sustainability: The lower energy consumption with our filter cubes also reduces CO2 emissions, which leads to an improved environmental balance.

Example: The PAINTBLOCK filter box from NeuFilter

The PAINTBLOCK filter cube from NeuFilter is a good example of a filter with a low pressure difference and a high absorption capacity. This combination makes it the first choice for dry separation and offers significant advantages both in terms of air balance and energy balance. Compared to standard filter cubes, the initial differential pressure is approximately 60% lower.

By choosing a filter cube with a low pressure difference, such as PAINTBLOCK, you can therefore not only increase the efficiency of your system, but also reduce operating costs and contribute to environmental protection.

How do I correctly install my NeuFilter product in my paint system?

Our specialists will be happy to advise you during installation.

The correct installation of your NeuFilter product in your paint plant is crucial for optimal performance and safety. Here are a few steps and considerations to keep in mind:

  • installation guidelines: Read the manufacturer's installation guidelines carefully.

  • positioning: Place the filter at the intended location in the paint system. Make sure it is easily accessible for future maintenance.
  • startup: After installation, you should run a test run to make sure that the filter is working correctly and that there are no leaks or other issues.
  • Pressure difference measurement: Perform an initial measurement of the pressure difference to document the initial state of the filter.
  • Installation log: Document the installation process, including all tests and measurements performed, for future references.

By following these steps and considerations carefully, you can ensure that your NeuFilter product is installed efficiently and safely in your paint plant. If you have any further questions or concerns, please feel free to contact NeuFilter's customer service.

Are there any special safety measures that I should take when using NeuFilter products?

Yes, certain safety measures should be observed when handling NeuFilter products, in particular dry separators such as PAINTBLOCK and PAINTGRID:

Expert installation: The installation should only be carried out by trained personnel to ensure that all components are correctly assembled and connected. We would be happy to provide you with information on how to set it up and how to install it correctly if you still need it.

Switch off the system: Before maintenance work or the replacement of filter elements begins, the system should be switched off and, for safety reasons, the power supply should be interrupted and secured against accidental switching on.

Personal protective equipment (PPE): Gloves, goggles and, if necessary, a respirator should be worn when servicing or replacing filters.

Proper disposal: Used filter elements should be disposed of in accordance with local waste disposal regulations.

No open fire: Since the filters can absorb materials such as paint particles that could be flammable, disposal should be carried out away from open flames.

By following these safety measures, you can minimize the risk of accidents and ensure the longevity of your NeuFilter products.

How can I tell when the filter is saturated or needs to be replaced?

Detecting a filter that is saturated or needs to be replaced is an important aspect of maintaining and operating your system safely. Here are some methods and signs that may indicate that your NeuFilter product needs to be replaced or serviced:

  • Damages: Any form of physical damage, such as cracks, holes, or worn areas, is an immediate sign that the filter needs to be replaced.
  • deformations: If the filter appears deformed or compressed, this could indicate an overload or possible damage.
  • material fatigue: Look for signs of material fatigue, such as fraying or fiber breakage, as these may affect the integrity of the filter.
  • Pressure difference: An increase in pressure difference above a certain threshold may indicate that the filter is saturated and needs to be replaced. The ultimate pressure difference can be found on our data sheets.
  • Airflow meter: One reduced airflow (flow rate) can also be an indicator of a saturated filter.
  • legal regulations, such as VDI6022, a German guideline that sets quality standards for the hygiene of ventilation systems and devices.
  • If you're unsure, it's always a good idea to contact NeuFilter customer service for more information.

By following these methods and signs, you can ensure that your filter is always in optimal condition and that your system is running efficiently and safely.

What do I have to consider when disposing of used NeuFilter products?

Appropriate disposal when treated depends on the paints used and local municipal regulations. If you have already disposed of your filters as residual waste, you can continue to do so. The usual waste code for this is 080112 paint and varnish waste with the exception of those falling under 080111 (paint and varnish waste containing organic solvents or other hazardous substances). In any case, the classification depends on the type of paint used. If your paint is considered toxic due to the solvent content, the filter can be dried. Please follow the manufacturer's instructions and disposal instructions in accordance with the paint manufacturer's DIN safety data sheet.
