Progressively denser synthetic media, it comes with PU frame with galvanised steel frame. The filters are tested as per ISO 16890-16 in European laboratories. Available ISO Coarse efficiencies and Energy rated as per EUROVENT (4/5).

Spectra pre Rod filter is a primary stage pre filter used commonly in stand alone system, AHU and other HVAC applications. The pleated synthetic filter media supported by Rods give higher media area and rigid structure enables lower pressure drop and less energy consumption. The construction of the filter is rigid, lightweight and easy to handle.

These are robust filters made of some layers of synthetic mesh that are non woven, sandwiched in between. The pleats are V shaped and rounded well to increase the dust arrestance of filters. Media is further enforced by metal expanded mesh to give extra rigidity to pleats so that peats would retain their shape at higher pressure drop.

Spectra Eco Pleat is specially designed to protect coarser filters with high dust arrestance. Designed with moisture resistance cardboard frame, engineered with expanded metal backed synthetic media, ECO pleat is fully incinerable.
