FAQ
Q1: What applications is this primary filter suitable for?
A: Ideal for commercial buildings, factory workshops, cleanroom pre-filtration, and HVAC systems. It effectively captures large particles like dust, hair, and fibers, extending the lifespan of medium/high-efficiency filters.
Q2: How often should the filter be replaced?
A: Replacement intervals depend on the operating environment. Generally, inspect every 3-6 months. Replace when resistance reaches the final resistance (e.g., ≥250Pa) or visible dust accumulation occurs.
Q3: Can it be cleaned and reused?
A: Not recommended. Washing synthetic fiber media reduces filtration efficiency. We advise replacing the filter cartridge directly for optimal performance.
- Premium Materials: High-strength frame + synthetic fiber media ensure low resistance, high dust capacity, and extended service life.
- Flexible Compatibility: Multiple sizes (customizable) and flanged/flangeless installation options to fit various ductwork requirements.
- High-Efficiency Filtration: Complies with EN779 standard (G1-G4 available), effectively protecting downstream high-grade filters.
- Cost-Effective & Durable: Replaceable cartridge design reduces long-term maintenance costs, offering better value than disposable filters.
