Overview: combined high efficiency filter, also known as the amount of wind / W type / V type filter, modular frame plastic frame, galvanized frame, aluminum frame, stainless steel frame Optional (used mostly for plastic frame combined). By a multi-chip low resistance, waterproof, fire retardant superfine glass composition V filter without clapboard structure, mounted in a frame, a large load, high efficiency air filters. Features: specifically designed for the needs of the design and development of wind capacity to achieve low resistance, medium expansion area than traditional big 1-3 times larger filter area can provide a longer service life. More likely to achieve greater efficiency and higher dust holding capacity at the same air volume, initial resistance is far lower than traditional filters, and therefore more energy-efficient, lower operating costs. Applications: all kinds of winds of terminal air purification system and a higher air cleanliness requirements for air conditioning and ventilation system filters
