VOC Filters and Cassettes


VOC Filters and Cassettes are gas filters filled with chemical adsorbents/ media, designed for easy handling and replacement. Stream Peak’s VOC Filters and Cassettes are available in different models to cater to different air treatment applications.

Particulate Filters

Pre-filters, absolute filters, electrical filters and high-efficiency filters.


Standard frame gas filter, incorporated with chemical media. This filter is widely used in the inside of air treatment units for industrial applications. It is suitable for air deodorization and purifications in public buildings, hospitals, laboratory, museums and archives, hotels, restaurants and many more.


The AP12 and AP18 chemical filtration modules are rugged plastic housings that contain chemical filtration pellets to ensure optimal performance with low-pressure drops. These modules are designed to minimize maintenance time and reduce operational cost. It is also available in 4 different sizes to suit all applications and are designed for easy handling and replacement. They can be applied either prefilled, directly from our production facilities or refilled through the removable caps.

The design of your system would determine which module is required. Factors that are taken into consideration include:

  • Available space
  • Air-flow volumes
  • Type and concentration of contaminants
  • Desired medial life

  • Chemical Media Specifications
Alphablend 8A This is our standard chemical media for this filter and consist of a blend of virgin activated carbon and Alphasorb 8, capable to remove a broad spectrum of malodorous and toxics compounds such as hydrogen sulphide, dimethyl sulphide, mercaptans, nitric oxide, formaldehyde and VOC’s among others.
Alphasorb 8 Potassium permanganate impregnated activated alumina spheres for the removal of oxidative compounds such as formaldehyde, ethylene and mercaptans.
Alphasorb 15 Caustic impregnated activated alumina spheres for the removal of chlorine and acid gases such as H2S.
Alphasorb 60 Virgin activated carbon for general odours & VOC’s adsoption.
Alphacarb N Impregnated activated carbon for the removal of ammonia and aminos.
Alphacarb HG Impregnated activated carbon for mercury vapour’s removal.
