Product Description

China Suppliers Air Filtration EU4 G4 Merv7 8 24x16x1 24x18x1 Filter Material Media
Our diverse product line features premium F5, F6, F7, and F8 medium-efficiency bag filters. These filters are meticulously engineered to serve as the ideal intermediate filtration solution in sophisticated air conditioning systems, delivering exceptional performance and superior air quality to meet the highest standards.
Designed with precision craftsmanship, the frame of our filters is crafted from top-quality aluminum alloy or robust galvanized plate, available in optimal thicknesses of 21mm or 25mm. This ensures enhanced durability and performance, promising long-lasting use even in the most demanding conditions.
Incorporating cutting-edge technology, the filter material is made of state-of-the-art melt-blown synthetic fiber. It features an innovative V-shaped bag structure that significantly maximizes filtration efficiency, ensuring cleaner air and better protection for your environment.
The inner framework is meticulously constructed with galvanized inner strips combined with sturdy galvanized pressure bars, ensuring exceptional stability and an extended lifespan. This robust design not only enhances longevity but also assures consistent performance over time.
Our thoughtfully engineered 'bag support grid' provides superior reinforcement, safeguarding the filter from collapse or deformation even under the most challenging conditions. Coupled with advanced hot melt technology, it effectively prevents excessive compression and leakage between bags, guaranteeing optimal performance and reliability for your filtration needs.
