Tri-Sorb 2 & 4 are thin-line filters that provide both molecular and particulate filtration. Their thin profile — just two and four-inch deep — allows easy use in current HVAC systems without the need for expensive modifications.

Molecular filtration is typically an after thought – for situations arise that were not planned for in the original HVAC system. This puts a premium on the ability to easily retrofit without expensive and messy construction projects.

Tri-Dim offers a full selection of molecular filtration bulk media to remove a broad spectrum of airborne molecular contaminants (AMC). The media types highlighted below are the more commonly requested, but specialty media is also available. 

Tri-Sorb M13 is a pleated hybrid filter offering both particulate and molecular filtration. With particle filtration, Tri-Sorb M13 provides MERV 13 performance per ASHRAE 52.2. This level of filtration efficiency is recommended by various agencies and organizations as one strategy to reduce the spread of airborne illnesses.

Tri-Sorb filters are available in either pads, triple stage filtration and dual stage pleated configurations and are designed to remove gaseous contaminants.

Tri-Sorb R offers both molecular and particulate
filtration and offers easy retrofit into existing systems.
Tri-Sorb R is offered in both a metal no header version
and a metal single header version – this allows for
easy interchange with current filters without the
costly retrofit of HVAC system.

The Tri-Sorb R M15 filter is a molecular filter that offers MERV 15 particulate efficiency – all with low resistance and easy retrofit into current HVAC systems. The Tri-Sorb R M15 is offered in a variety of frame styles – single header and no header box style – this broad offering of frame styles allows for easy and convenient retrofit into most all housing/holding frame configurations. The no header version will work in applications using a double header filter.

Tri-Sorb VH is a V-bank carbon filter that features special honeycomb panels. These panels hold 24 lbs of carbon per 24 x 24 x 12 filter—either 100% 6 x 12 mesh, industrial-grade CTC high-activity carbon, or a 50/50 blend of carbon and potassium permanganate. These types and quantity of carbon allow Tri-Sorb VH to be used in applications with heavy concentrations of unwanted gases and to control a wide range of odors.

Tri-Sorb V M15 packs 11.5 lbs of carbon into a nominal
24 x 24 x 12″ sized filter. Unlike most carbon filters,
Tri-Sorb V M15 utilizes a smaller mesh size, which
exposes more of the carbon’s surface area to the air
flow. This larger open surface area translates into a
higher removal efficiency of airborne molecular
contaminants.

Tri-Sorb XL is available in three distinct grades – Heavy Duty, Medium Duty and Light Duty to match the demands of your applications. The Heavy Duty has the maximum amount of media and the highest carbon loading with 225 grams of
carbon per square foot of filter face area in a two-inch deep filter. The Medium Duty has 150 grams of carbon per square foot of filter face area in a two-inch deep filter and the Light Duty offers 140 grams of carbon per square foot of filter face
area in a two-inch deep filter offering options for less demanding applications.

Various pollutant systems require both adsorption and reactive chemistry for effective removal of all pollutants. Therefore, Hydrosil created a product called XB-17. XB-17 is a 50/50 blend by volume of activated carbon (HS-AC) and HS-600. The blend is commonly used to remove volatile organic compounds (VOC) from gas phase.

Hydrosil’s HS-AC is highly active granular activated carbon (GAC) manufactured via high temperature steam activation from selected grades of coconut shell. Coconut shell activated carbon is known for its high hardness, low dust, and low ash content. The HS-600 is a hard zeolite in the granular form. Its’ high impregnated level of potassium permanganate and insignificant dusting attributes make it an ideal media for gas phase filtration. The two products blended together casts a wide net to remove a handful of inorganic and organic compounds.
