Paper Air Filter Cartridge 188x120
Product description
The Paper Air Filter Cartridge is a high-efficiency filtration solution designed for air intake systems requiring reliable particulate removal. With its compact dimensions, this cartridge delivers robust filtration performance in a space-saving package, making it ideal for equipment where larger filters cannot fit.
This element is constructed from premium F7-grade pleated cellulose filter paper, featuring a graded density structure where the outer layers capture larger particles and progressively finer layers trap smaller contaminants closer to the core. This design achieves up to 99.5% filtration efficiency for airborne particles, effectively protecting downstream components from dust, dirt, pollen, and other contaminants that would otherwise cause premature wear.

product features
-
* F7 Filtration Grade: Features premium pleated cellulose filter paper with F7 filtration rating, effectively capturing fine particulates and airborne contaminants.
-
* High Filtration Efficiency: Achieves up to 99.5% filtration efficiency for airborne particles, protecting sensitive equipment from premature wear.
-
* Hydrophobic and Oil-Repellent Media: Special fiber filter material resists moisture and oil aerosols, preventing media blinding and maintaining low pressure drop even in challenging environments with oil mists or humidity.
-
* Graded Density Structure: The density of the filter material increases progressively from outer to inner layers, achieving high efficiency, low resistance, and large dust-holding capacity.
-
* Reliable Sealing: Features a durable sealing ring at the connection point between the filter element and housing, ensuring no airflow short-circuiting and preventing impurities from bypassing the filter.
1. Special design can achieve an effective filtration area of 100%;
2. Each component adopts a seamless fusion method, which solves many problems that originally existed in use and ensures safety;
3. The design adopts a metal folding frame, which can be reused and replaced;
4. The density of the filter material shows an increasing structure, achieving high efficiency, low resistance, and large dust capacity;

Filtration grade explained
The F7 filtration grade follows EU standard classification for air filters (EN 779). This classification defines the filter‘s ability to capture airborne particulates:
| Grade | Average Efficiency | Typical Application |
|---|---|---|
| F5 | 40-60% | Coarse pre-filtration |
| F6 | 60-80% | General ventilation |
| F7 | 80-90% | Fine filtration (this product) |
| F8 | 90-95% | High-efficiency fine filtration |
| F9 | 95-98% | Very high-efficiency fine filtration |
An F7-grade filter effectively captures fine dust, pollen, mold spores, and other airborne particulates, making it suitable for protecting sensitive equipment and maintaining clean air in industrial environments.

FAQ
Q: Can this filter element be cleaned and reused?
A: Paper air filters are typically designed as disposable and should not be cleaned for reuse. Cleaning can damage the delicate cellulose fiber structure, creating pinholes that allow contaminants to bypass the filter. However, the metal folding frame design does allow for easy replacement when service is needed.
Q: How do I know when to replace this filter element?
A: Replace when the differential pressure indicator signals, when airflow is noticeably restricted, or during scheduled maintenance intervals. Many systems are equipped with a restriction gauge or service indicator that alerts when the filter needs replacement. For applications without indicators, typical replacement intervals range from 6 to 12 months depending on operating conditions.
Q: How does the sealing ring prevent bypass?
A: The filter element features a reliable sealing ring at the connection point between the filter element and the filter housing. This ensures that airflow does not short-circuit around the element and prevents impurities from entering the downstream without passing through the filter media.
