This RS PRO HEPA filter is a high-efficiency option that ensures strict particle filtration within your ventilation system. H11 grade filters such as this one are used in micro-technology and industrial environments to capture and contain the finest dust particles.
The product's glass fibre material is made from extremely fine mini-pleated thread, so it remains uniform throughout the unit and can capture more dust particles. The filter has an excellent particle retention ability due to its thermoset resin laminate, which means only air can pass through.
The filter is sealed in polyurethane and fixed to a galvanised steel frame, so it remains securely in place once installed. Its glass media helps prevent the build-up of moisture and is less likely to shed fibres than other filtration materials, keeping your system protected from contamination for longer.
