Spectra PU Series Rigid Pockets are a premium high efficiency air filter designed for critical or harsh air handling units. Pockets are extremely durable and will perform flawlessly over a long period of time. The depth-loading filter media is manufactured in a progressive den­sity multi-layering technique to ensure high dust holding capacity with lowest pressure drop. For the user, this results in long filter life and low energy and maintenance costs. The pocket filter medium is inherently rigid, with a welded rib construction to form a pocket with the highest possible function security in even the most brutal air pressure and high dust-laden environments.

Spectra TP welded stiff pocket filters are aerodynamically designed for full media utilization. The filter incorporates high performance synthetic filter media featuring progressive density and high dust holding capacity, designed for critical or harsh air handling units. The depth-loading filter media is manufactured in a progressive density multi-layering technique to ensure high dust holding capacity with the lowest pressure drop. This translates to prolonged filter life and reduced energy and maintenance expenses for the user. 

Spectra AP Pockets stand out as highly efficient air filters specifically engineered for demanding air handling units. These filters exhibit exceptional durability, guaranteeing optimal performance over an extended lifespan. The filter media, designed for depth-loading, undergoes a progressive density multi-layering process, ensuring a remarkable dust holding capacity coupled with minimal pressure drop. This translates to prolonged filter life and reduced energy and maintenance expenses for the user. The inherently rigid pocket filter medium features a welded rib construction, creating a pocket that maintains its functionality with utmost reliability, even in harsh conditions characterized by intense air pressure and high levels of dust.

Spectra Drop Shield Reverse pocket (SDSRP) filters are unique premium hydrophobic pre-filters in reverse air flow direction where space is a constraint. The SRP pocket filters serve as efficient pre or final filters in air intake systems of Gas turbines in any environmental condition (including offshore, marine) and in any climate (including tropical). They efficiently remove air borne particulate matter but also snow, mist and fog acting as a filter and a coalescer in one. SDSRP filters are specially designed for the elimination of free water and air borne salt crystals. Where subsequent final filters are placed, they protect them not only from coarse dust but also from running in wet conditions. The SDSRP filters do significantly prolong the filter lifetime of the final filter and increase their operational safety.
