G4 Iso Coarse 60% 146 x 396 x 20 mm

Manufacturer's Name Murano Feniks: MF/FLT/OC G4 ISO COARSE 60% 146x396x20 mm

Flat filter with a metal frame for coarse filtration in mechanical ventilation, recuperation and air conditioning units. The construction of the filter is made of a synthetic polyester non-woven material laid flat and then tightly glued to a metal frame. Filter fleece is 100% polyester fibers with increasing density at the air outlet side of the filter. Provides very low air resistance throughout the entire period of filling the filter with impurities. The frame flat filter G4 Iso Corase 60% in the dimension 146x396x20 mm allows for capturing 60% of coarse particles from the air, i.e. leaves, insects, hair, sand, ash, fine sand, plant spores, pollen and other impurities larger than 10 μm (micrometers) . It is included in the coarse filtration pre-filters, thus this filter allows for basic air filtration in mechanical ventilation systems with heat recovery, called recuperation. Our filters are made of materials that meet high energy classes to ensure the lowest possible consumption of electricity by your recuperator.
