Spectra Dust Collector filter pad is  progressive density fiber glass  allows the pollutant to penetrate deep into the media, along with the harmless tackifier over the fibers arrest the pollutant and make it stick together. The filter pads can be constructed  with suitable frames depend on the use of the application. 

Spectrum Drop Shield rigid 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 airborne particulate matter but also snow, mist and fog, acting as a filter and a coalescer in one. DS rigid filters are specially designed for the elimination and drainage 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, thus significantly prolonging their life and increasing their operational safety.

Ruggedly constructed, heavy duty, high efficiency filter. A special dual layer, graded density media ensures extremely high dust holding capacity & therefore lower operating pressure loss.

Spectra Pre-TM filters are used for supply, exhaust and circulating air filtration in a Turbine application which built for high dust holding capacity, used in all industrial gas turbine and compressor 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.
