Peregrine and Lee Aerospace Partner on Clean Air Solution for Challenger 600 Series Aircraft


Peregrine and Lee Aerospace have once again joined forces to deliver Aviation Clean Air (ACA) system installation data and Supplemental Type Certificates (STC’s) for the Challenger 600 Series of aircraft. The ACA pathogen disinfection technology eradicates the COVID-19 virus.

The Challenger 600 family of aircraft includes the following models: Challenger 600/ Challenger 601/Challenger 604/ Challenger 605/ Challenger 650 series including CL-600-1A11, CL-600-2A12, CL-600-2B16 (601-3A Variant, 601-3R Variant, and 604 Variant).

Challenger aircraft are equipped with fresh air systems that deliver 100 percent outside air with leading cabin air replacement rates. The ACA ionization technology offers an added layer of protection in the cabin.

The STC and installation hardware kit for Challenger 600 series aircraft are available exclusively from Peregrine and can also be purchased and installed at Bombardier Service Centers or qualified Part 145 repair stations.

“We are proud to partner with Peregrine again on this all-important health protection ACA technology,” said Jim Lee, founder and president of Lee Aerospace. “Assuring that passengers and crew feel safe flying again is vital to the growth and recovery of business and private aviation.”

Peregrine-developed STC’s for the ACA system are also available for aftermarket installation in the Citation 560XL, Gulfstream G-IV and GIV-SP models, Falcon 50 and 900, and the Bombardier CL600 series family. Peregrine expects to announce additional air certification agency validations for these STCs to support greater accessibility to this technology.

“This system implements a layered defense for protecting aircraft passengers and crew by supplementing cleaning procedures with an active, always-on system that provides continuous, effective neutralization of harmful pathogens,” Lee said. “This installation demonstrates the availability of the ACA system to users and operators of most sizes of business aircraft.”

The Aviation Clean Air units offer a proactive air and surface purification system for aircraft, providing immediate clean, safe, and healthy interior air. In addition to removing odors and allergens, their patented ionization technology kills pathogens throughout the cockpit and cabin, including, but not limited to:

  • COVID-19
  • Bacteria associated with SARS
  • Bird Flu (H5N1)
  • Swine Flu (H1N1)
  • Staph
  • Eliminating mold spores, MRSA, coli, Tuberculosis, C.diff, pneumonia, and more

Testing at an independent laboratory showed that the ACA system was 99 percent effective in eliminating SARS-CoV-2 (COVID-19).
