G4 Iso Coarse 60% 265 x 523 x 30 mm

Manufacturer Name Murano Feniks: MF/FLT/WRD G4 ISO COARSE 60% 265x523x30 mm

Flat filter with a frame for coarse filtration in mechanical ventilation, recuperation and air conditioning units. The structure of the filter is made of a synthetic polyester non-woven material laid flat and then tightly glued into a cardboard frame. The 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 265x523x30 mm allows to capture 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.
