1. Reinforced Waterproof Paper Frame & Tight Sealing: Upgraded thickened waterproof hard paper frame features integrated cutting and compression molding, with neat edges and no burrs. It effectively resists moisture, deformation and cracking in humid ventilation environments. The close-fitting structural design ensures zero air leakage after installation, avoiding unfiltered air mixing into the ventilation system and guaranteeing overall filtration accuracy.
2. Standard G4 Grade Stable Filtration Performance: Strictly compliant with EU industrial filtration standards, the filter media achieves stable G4 filtration efficiency, accurately intercepting particles above 5μm. Consistent filtration effect is maintained under long-term high-speed air flow operation, solving the problem of unstable filtering capacity of inferior filters and ensuring long-term reliable air purification effect.
3. Energy-Saving Low Resistance & Super Large Dust Holding: The three-dimensional fluffy fiber structure enhances air permeability greatly with ultra-low initial wind resistance, which does not increase the load of ventilation fans and reduces equipment power consumption. The optimized fiber laying process enlarges the internal dust storage space, effectively prolongs the service life of the filter and reduces frequent replacement costs.
