Collins Aerospace’s HEPA filter kit improves cabin air purity on Dash 8 aircraft

  • Designed to remove and trap at least 99.97% of airborne particles with a diameter of 0.3 micron

WINSTON-SALEM, NC (June 16, 2020) – Collins Aerospace Systems, a unit of Raytheon Technologies Corp. (NYSE: RTX), has developed and introduced the only Cabin Air Recirculation high-efficiency particulate air (HEPA) filter installation kit for use on Dash 8 (-100/-200/-300) aircraft. The HEPA filter kit mounts inside an aluminum enclosure along with a prefilter and together trap at least 99.97% of the harmful airborne particles that have a diameter of 0.3 micron. These include bacteria, viruses, pollen, dust, mites and other microscopic airborne contaminants in aircraft environmental control systems. To date, five separate airlines operating Dash 8 aircraft have placed orders and adopted the Collins Aerospace HEPA filter solution.

In the current cabin environment, air is drawn from the cabin where it is mixed with fresh air before being distributed back to the cabin with minimal filtering. Designed as a retro-fit for Dash 8 (-100/-200/-300) aircraft, the upgraded HEPA filter solution enables cabin air to be filtered before reaching the condenser mixer.

“Our customers are searching for partners and solutions that can provide higher air quality for their passengers as we work together through the changing aviation landscape,” said Trevor Skelly, vice president and general manager for Collins Aerospace. “These HEPA filter kits are simple to install, improve cabin air purity and provide a more comfortable aircraft environment at a low replacement cost.”

“While this specific solution is an exclusive drop-in replacement for Dash 8 operators,” continued Skelly. “We’re ready and able to partner with airlines and operators of other platforms to help deliver a HEPA filtering solution to best fit their existing fleet, as well.”
