These compact high efficiency filters are constructed by micro-fiberglass filter paper formed into mini-pleats which are separated by continuous thermoplastic wires. The mini-pleat packs form rigid V-shaped dihedrons sealed within end panels and support frame. Both cell sides and frame are made in plastic, ensuring the complete possibility to incinerate exhaust filters.
Applications
They are used in air treatment units and ventilation plants either as final filters or as pre filters for absolute ones. No fibers are lost by the media, so these filters are particularly well suited for applications like food processing and pharmaceutical production. RP filters are ideal for use in VAV (Variable Air Volume) systems and everywhere there is discontinuity in air flow.
Features
They are available in 4 models: RP 60, RP 80, RP 90 and RP 95.
The efficiencies and filtration classes in accordance with EN ISO 16890 and EN 779 and the initial pressure drops at the rated flow rate for standard formats available are:

| Filtration class according to EN ISO 16890 | ISO ePM2,5 55% | ISO ePM1 55% | ISO ePM1 70% | ISO ePM1 85% | ||
| Filtration class according to EN 779:2012 | M6 | F7 | F8 | F9 | ||
The limit working temperature is of 90°C approx.
Capacities comprised between 0% and the 125% of the nominal ones are allowed for a good working of filters. It is possible to consider, inside this range, a linear correspondence between resistance and capacity.
Installation & service
It is advisable to foresee a pre-filtration stage before these filters. The RP filters can be installed into proper holding frames having frontal access and usually designed to fit any possible pre-filters. It is advisable to replace these filters once having reached a resistance of 250÷300 Pa.
