It provides continuous high efficiency air purification for low level contaminated air streams ranging in volume from 500 to 4000 CFM. These systems are typically used in free standing applications where fine purification of the air in a room is needed.

PFUs are most often used in computer control rooms as polishing filters to provide added assurance of air quality.

Christie's Auction House case study brochure
Christie’s Auction House has sold precious pieces of artwork and estate for hundreds of years. The first U.S. auction was held in 1977 in Rockefeller Center, New York, and since then, the U.S. branch has continued to host numerous priceless artifacts at auction. In 2015, sales totaled $7.4 billion.

Needless to say, Christie’s must take extra precautions to protect these valuable pieces. Even the slightest amount of pollution in the air can tarnish delicate artifacts, so it is incredibly important to keep the air inside the auction house free of all contaminants.

Christie’s looked to the air purification market for a solution to super-purify the air in its facilities.
