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 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-Pre ROD filters are used for supply, exhaust and circulating air filtration in ventilation systems which built for high dust holding capacity, used in all industrial, HVAC and pharmaceutical application. Where subsequent final filters are placed, they protect them from coarser dust and fog, thus significantly prolonging their life and increasing their operational safety.

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.
