Product Details What is a Cassette Filter? G4 cassette filters are a type of filter technology used in air filtration systems. “EU” standards are a system that classifies the performance of air filters determined by the European Union. EU classification is usually made according to the EN 779 standard. The G4 level is a classification that indicates filtration efficiency. EU4 filters are typically used in ventilation and air conditioning systems and can capture between 60 and 70 percent of particles in the airflow. This effectively captures medium-sized dust particles and contaminants in the environment. Cassette filters are a configuration where a number of bag filters are combined. These types of filters are typically used in industrial applications where high air flows are required. Cassette Filter (Panel Filter) is one of the other products of the air filter group , better known as the pre-filter . It constitutes an important part of the industrial field of the air filter class. It captures coarse dirt in compressors, air conditioning units, ventilation ducts or specially designed places. Cassette filter (Panel Filter) is made in square or rectangular shape as the name suggests. We can prepare the contents of the cassette filter in different types. In addition to the galvanized and cardboard outer structure, it is possible to prepare the contents as glass fiber, fiber, active carbon, polyurethane, fortitude, sponge, carbon coal.
Are EU4 and G4 Filters the Same? The G4 and EU4 filter classes represent similar performance levels. Both are similar in their ability to capture particles from the environment. The G4 class is a class of air filter typically used in ventilation and air conditioning systems and has a particle retention efficiency of 90 to 95 percent. Class EU4 is also a classification indicating air filtration efficiency, and particle trapping capacity varies between 60 and 70 percent. However, G4 and EU4 belong to different classification systems. G4 is classified based on ASHRAE standard while EU4 is determined by European standards. Both filter classes can effectively capture medium-sized dust particles in the environment. These types of filters are generally used in places such as office buildings, industrial facilities, shopping malls.
Classes G1 and G2 are filters with low efficiency levels used in air filtration systems. What is G1 Filter? It is typically in a filter class that can capture 65 to 75 percent of particles in the airflow. It can effectively trap larger particles. G1 filters are generally used to meet basic air filtration needs. What is G2 Filter? The G2 filter is in a filter class that can capture 80 to 90 percent of particles in the airflow. It has the ability to capture finer particles than G1. G2 filters are generally used to meet moderate air filtration needs. These filter classes are typically used in environments with lower air quality requirements. For example, G1 or G2 filters can be used to meet basic air filtration needs in some sections of industrial facilities, warehouse areas or building entrances. However, air quality requirements can vary from application to application. Therefore, the filter class to be used should be determined based on the needs of the specific application and the ambient air quality requirements. This type of filter is used to meet basic air filtration needs and to slightly improve air quality. However, more sensitive environments may require filters with higher efficiency levels. Therefore, when determining air quality requirements, the characteristics of the environment and the intended use must be taken into account. WASHABLE CASSETTE FILTER (POLYURETHANE) The filter used as a pre-filter is in the G2, G3, G4 class. Being washable extends the life of the filter and makes it economical. We produce cassette filters in special sizes according to your requests.
