Product Description
The Close Pleat Box HEPA Filter uses ultra-fine glass fiber or synthetic fiber as the filter media, achieving higher filtration efficiency and lower air resistance.
This design reduces the filter's size and weight, facilitating installation and maintenance, and lowering long-term operational costs.
The frame is usually made of aluminum alloy, offering high strength and corrosion resistance.
It is widely used in cleanrooms, laboratories, hospitals, and pharmaceutical industries, appreciated for its high efficiency, low resistance, lightweight design, long service life, and cost-effectiveness.
