Donaldson’s high efficiency filtration removes particulate contamination from critical environments. Donaldson engineers have worked closely with the aerospace and defense industries to design filters that operate at the highest efficiencies, are easy to maintain, and provide superior protection for passengers, crew, and equipment.

The breadth of our experience in all types of air filtration and close partnership with major airframe manufacturers and airlines enabled us to develop a product line that includes cabin air filters, chemical filters, and specialty filters for the protection of avionics and other equipment.

Behind all our filters stand 80 years of Donaldson filtration experience, as well as our corporate commitment to technologically advanced products and responsive customer service worldwide.

Donaldson and Proponent

With extensive experience in supporting the MRO, OEM and airline markets, our organization offers innovative inventory and supply chain management solutions to OEM and aftermarket customers.

Donaldson brings cleanroom filtration technology to aircraft cabin recirculation systems.

Donaldson Company is the leading manufacturer of HEPA (High Efficiency Particulate Air) filters. HEPA filters have a removal efficiency of 99.97 percent of all 0.3µm particles. The 0.3µm benchmark is used in efficiency ratings, because it approximates the most difficult particle size for a filter to capture. The filters are even more efficient in removing both smaller particles (tobacco smoke, atmospheric dust, microbiological material) and larger ones (lint, pollen).

HEPA filters can be especially effective in removing bacteria and microbial aerosols from aircraft cabin air.

Because these microbiological organisms are likely to stick to larger particles — in the 1µm to 10µm range — the filter efficiency for particles carrying bacteria or virus is much higher than the minimum efficiency.

The filters remove dust particulates, allergens, bacteria, viruses and odours from cabin air.

Donaldson Le Bozec HEPA filters meet or exceed Airbus specifications for aerosol particulate removal. Our filters for single-aisle and long-range aircraft offer the highest efficiency ratings available.

Proponent and Donaldson Filtration Solutions are ready to negotiatiate attractive prices and excellent availability for airlines, lessors and MRO's.
