UA-400 Air Purifier

Parker UA-400 PDF

There is more awareness and focus now than ever before on the air that we breathe and the desire to filter out and remove air pollutants such as allergens, dust, viruses, mould and bacteria that may be floating or airborne.



Parker Hannifin, the trusted, global leader in filtration systems innovation, is excited to introduce the UA-400 Air Purifier. The basis of the design is a particle irradiation and filtration system that uses advanced technology to purify and improve the air quality within a wide variety of indoor spaces where we live, work, and play.

Third party testing has shown almost 100% micro-organism deactivation in 15 minutes! This unit is designed for commercial purposes with a high concentration of people, or a large room application.

The UA-400 Air Purifier is a mobile particle irradiation and filtration system that utilizes electrostatic, ultraviolet energy, and high efficiency filtration to neutralize and clean ambient air within an occupied room or space.
The innovative design of UA-400 combines Electrostatic Precipitator (ESP) and Ultraviolet Germicidal Irradiation (UVGI) wavelength technology with high efficiency HEPA filtration to provide continuous cleaning of air in an indoor space. The combination of ESP, UVGI and HEPA filtration captures, irradiates and filters bacteria, dust, mould spores, odours and virus particles as small as 0.3 microns which is about 250 times smaller than a human hair.

UVGI uses short-wave ultravio­let C band (UV-C) energy to inactivate viral, bacterial and fungal organisms. UV-C has effectively been used for decades to reduce the spread of bacteria. In addition, UV-C radiation has been shown to destroy the outer protein coating of the SARS-Coronavirus and may also be effective at inactivating the SARS-CoV-2 virus.

Theory of Operation

As the air enters at the base of the unit and into the first stage, large particles are filtered out of the air stream by the pre-filter. The air then passes into a second ESP stage, where particles are captured up to 97% of 0.3 micron. Next, the air passes into a third stage, where particles are dosed with high-intensity UVGI energy. In the fourth stage, the high-efficiency HEPA filter captures particles as small as 0.3 micron, and the UVGI high intensity energy irradiates them. The cleaned and purified air is then returned out through an air diffuser and back into the indoor space. Prior to the air diffuser, there is also an optional fourth stage where the air can pass through a carbon filter to help with odours in difficult environments.
