Brief:Features The outer frame of this deep-pleat separator Hepa filter is made of aluminum or galvanized, which is wear-resistant and dust-free. The filter element is made of glass fiber and PP paper, which has high dust capture and breath ability. The corrugated aluminum foil partition or paper partition can accurately maintain the spacing between the pleats, maximizing the use of filter material with minimal resistance. The aluminum foil thickness is 0.03mm, and the ripple height is 4mm, which can fully ensure the area of the filtering material and the quality of the filter. The filter material is made of high-density paper made of ultra-fine glass fiber.
