SilverGuard™ Antimicrobial-coated Ductwork

Your customers realize that harmful bacteria can contaminate their HVAC and ventilation systems, threatening the health and safety of everyone in the building. However, potential contamination from destructive microbes is not limited to terrorist attacks, it is a day-to-day concern.

Outdoor pollution levels have improved over the past 20 years, but many schools, hospitals, day-care centers, aquatic facilities, and offices have become much tighter buildings with minimal fresh air flow. These buildings retain pollutants at greater levels. If maintenance of the HVAC system is haphazard and moisture is present, bacteria, mold, mildew, and other fungi can thrive.

Dirty Duct

Unmaintained duct can be a breeding ground for mold, mildew, and other fungi.

Most of the 300,000 known types of mold are harmless, but scientists are concerned about the potential dangers of exposure to molds that can produce mycotoxins, natural compounds that can cause serious respiratory problems.

In response to the rise in asthma and allergies among schoolchildren today, the U.S. EPA has issued new air quality standards to provide additional protection for children and asthmatics. The governor of California has also signed a bill creating the Toxic Mold Protection Act, which sets the toughest toxic mold standards in the nation.

With a focus on HVAC systems, members of ASHRAE are studying retrofit programs to improve health and safety in existing buildings, and design features that could be incorporated into new buildings to improve health and safety.

You Have a Revolutionary New Safeguard

The first line of defense against destructive microbes is a clean and well-maintained HVAC system with good air distribution.

McGill AirFlow's SilverGuard ductwork is a second line of defense in the battle for good indoor air quality (IAQ).

SilverGuard antimicrobial ductwork inhibits the growth of bacteria, mold, mildew and other fungi on its coated surfaces.

SilverGuard ductwork is the perfect solution for applications where indoor air quality is an issue, such as food preparation facilities, hospitals, day-care centers, nursing homes, and schools. It is ideal for both consumer and industrial installations — anywhere bacteria, mold, and mildew grow.
