We represent one of the finest air filtration system manufacturers in Cosatron and are proud to offer their technology on your next project.
Importance of Quality Air Filtration
Indoor air quality has become a much larger topic of concern in recent years. With people spending 90% of their time indoors, federal, state, and local legislators have begun to institute stricter regulations for air filtration with the goal of creating healthier indoor air environments. Even buildings that appear clean can expose their occupants to a number of airborne contaminants without the proper air filtration systems in place.

How Does Excitation Work?
Standard mechanical systems are designed to remove particles that are larger than 3 microns. However, 98% of all particles are smaller than 3 microns and are therefore less influenced by standard HVAC systems. Excitation systems counter this by accelerating the natural process of conglomeration, a process by which particles collide, stick together, and grow. As particles reach 3 microns, they become air entrained and return to the mechanical filters for removal.
This is how excitation systems effectively improve indoor air quality by controlling the contaminants inside buildings. Excitation is the most effective means to minimize contaminants in a building by controlling and reducing particulate levels. This creates safer and more comfortable buildings and, as a bonus, can reduce energy usage and overall operating costs. Excitation is a unique, patented, high-tech means of providing clean air by increasing the size of the particulates in a given space, allowing them to be transported by the HVAC system to the filters to be removed.
Frequently Asked Design Questions
- What is the static loss of your system? 0.05”. The grids are 87% free area and have very little associated static loss.
- How much power/energy does the equipment use? The generator uses 50 watts of power
- What is the required power supply? 120v
- Are the units custom? The units are engineered for each application.
- Standard practice has the Series 1000 Units designed for the available wind tunnel dimension of the AHU.
- Standard practice for the Series 2000 Units is sizing them per standard filter velocities; 500-550 fpm, when the companion filter is used. If the filter is remote the units are designed for 825 fpm.
- Can the Units be installed in existing equipment? Yes, the units require 9” of space.
- Can the Units be installed at the factory? Yes, coordination can occur and the units can be shipped directly to the AHU manufacturing facility.
- What are good applications of the technology? Any in which you would like to clean the air outside of Grease Duct Applications and 100% humidity with moisture droplets. The Cosatron grids have electric fields. The grease would adhere and the moisture could shut down the systems until they dry out.
- Where are the Units installed? They are installed on the return side of the AHU after the filter.
- Can the Units be used to clean outside air? Yes, this application would be a single pass application and a final filter is required, MERV14 or HEPA.
- Can any MERV Rated filter be used with the Units? Yes, however keep in mind in a recirculating fashion a MERV8 is typically recommended. The higher the MERV Rating the smaller the excited contaminants are, therefore the conglomeration to 3 microns takes longer.
- Do the Units increase filter changes? Yes, the units make the filters 50% more efficient. The filters will capture more contaminants and filter frequency changes will go up. How much more frequent depends on how dirty the air is.
- Do the Units remove gaseous and particulate contaminants? Yes
