Outside Air Intake


Controlling airborne pollutants is essential to maintain a comfortable indoor environment in hospitals. Twin Filter is specialized in manufacturing air purification systems that remove gaseous and particulate contaminants. Pollutants can come from inside and oustide the hospital.
Outside sources of odors, including the heliopad, incinerators, loading docks, ambulances, and waste diposal units, are usually located in the rear of  the building mostly near the HVAC air intake. Emissions from nearby industrial facilities or residential furnaces can also result more pollutants.
Inside sources can be breakrooms, cafetarias, cleaning compounds, laboratories, and the use of special medical equipment or machinery. Also office furnishings and printers can worsen indoor air quality.

For clean indoor Twin Filter offers an extensive product selection of Purafil. From pleated chemical filters to modular front and side acces units. Our systems are designed for easy maintenance and are incorporated into your supply or return airstreams.
We offer a broad selection of dry-chemical adsorbents called media. The media removes contaminants through chemisorption. The contaminants are chemically transformed into hramless solids remained trapped inside the media. Gaseous pollutants that are trapped are for example; sulfur dioxide, Nitrogen oxides, Hydrocarbons, VOC, Ozone, Formaldehyde, Mercaptans and Tobacco smoke.
