Panel filters

Panel filters are air filters mainly used in heating, ventilation and air conditioning (HVAC) systems, as well as in industrial processes and clean rooms. They are designed to filter particles, such as dust, dirt, pollen, bacteria and other contaminants, from the air. This makes panel filters an essential component for improving air quality, reducing allergies and ensuring the efficiency of HVAC systems. as pre-filters in multistage air handling units for various applications. 

Construction and operation

A panel filter usually consists of a frame (usually made of cardboard, plastic or metal) in which a filtration material is placed. The filtration material can vary depending on the type of filter, but it is usually a combination of synthetic fibres, steelwire, fibreglass or carbon. The material has a certain density and structure that allows airflow to pass through, while retaining particles or impurities in the air. 

Applications of panel filters

Panel filters are widely used in:

1. HVAC systems: They are used to purify air and improve air quality in both commercial and industrial buildings. This not only helps protect the health of the people there, but also makes the system work more efficiently by preventing dust and dirt from blocking the air ducts or heat exchanger.

2. Industrial processes: In factories and manufacturing environments, panel filters are often used to clean air discharged by machines or processes. This prevents harmful substances or contaminants from polluting the environment.

3. Cleanrooms: In laboratories, hospitals or other controlled environments, high-quality panel filters are used to ensure sterile air quality.

4. Food industry: Filtration in demanding air handling, air conditioning and ventilation systems to capture grease and oil, capture mist and suitable for use in extractor hoods. This reduces the need for exhaust duct cleaning, prevents fires, extends the life of fans and motors in the exhaust duct and improves air quality.

Advantages of panel filters

1. Cost-saving: Panel filters protect downstream, higher-quality filters from damage and premature failure. This can save costs, as expensive filter elements in the final filter stages need to be replaced less frequently. 

2. Improved air quality: They help to clean the air and reduce impurities, which can contribute to a healthier living or working environment.

3. Energy efficiency: The use of a good panel filter can increase the efficiency of an HVAC system because airflow is less obstructed by contaminants. And, panel filters with pleated media, promotes airflow and maximizes the dust holding capacity (DHC). Lower pressure drop reduces energy consumption and lower operating costs.

Available filter classes panel filters

• Coarse 35%
• Coarse 70%
• ePM10 50%
• ePM10 70%

Panel filters are a cost-effective and versatile solution for filtering air in various applications. They help improve air quality, save energy and optimize the operation of HVAC systems. Despite their limitations in terms of fine particle filtration, they remain a popular choice for industrial applications.

When choosing a panel filter, it is important to consider the specific needs of the system, the desired air quality and the frequency of replacement to ensure the best performance and efficiency.
