The Spectra SMF Pocket Filter offers high efficiency filtration while maintaining low resistance to airflow. The non-shed media eliminates fibre migration downstream, and the ultrasonic welding provides zero leakage from pocket edges. The open throat design and the precise pocket spacing produces a product that is aerodynamically balanced and provides excellent all-round performance.

Spectra PTP 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 significantly 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 very 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 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.
