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.

Spectra Cell Compact mini pleated filters offer substantial advantages over conventional deep pleat ASHRAE filters, not the least of which are higher flow capacities, less space, reduced resistance to flow, and greatly enhanced dust holding capacities. It serves as an excellent final filter for air intake systems of combustion engines and as a final filter in HVAC systems.

 

The Spectra Cell Deep pleat is a ruggedly constructed, heavy duty filter which has a higher media area and  ensures extremely high dust holding capacity with lower operating pressure, stable performance at variable airflow. Filter media layers with aluminium separators makes the air to flow through the entire media area and increase the lifetime of the filter.

High efficiency deep pleated HEPA filters are used for removal of airborne contaminants, including fine dust, smoke, soot and microorganisms.
