G4 Iso Coarse 70% 287 x 287 x 48 mm

Manufacturer's Name Murano Feniks: MF/ZLX/CRD G4 ISO COARSE 70% 287x287x48 mm

Partition filter with cardboard frame for coarse filtration in mechanical ventilation, recuperation and air conditioning units. The structure of the filter is made of a synthetic material in pleats resembling a slightly stretched accordion, then tightly glued into a cardboard frame. This form of the filter cartridge allows for more effective use of the frame volume by obtaining a larger filter area, ensuring longer filter operation. Filter fleece of synthetic material with increasing density on the air outlet side of the filter. Provides very low air resistance throughout the entire period of filling the filter with pollutants. The pleated G4 Iso Corase 70% cassette filter in the size of 287x287x48 mm allows capturing 70% 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.
