Porvair engineers new patented HEPA filters

Porvair Filtration Group has engineered a patented, validated range of high flow, high strength, radial flow HEPA filters

Developed in response to the challenging demands of the US Department of Energy, Porvair Filtration Group has engineered a patented, validated range of high flow, high strength, radial flow HEPA (High Efficiency Particulate Air) filters. These filters are capable of handling large volumes of gases at high differential pressures in high humidity environments.

Within large volume settings, HEPA air filtration systems circulate air in a laminar flow environment, thus removing any airborne contamination before it is re-circulated back into the environment.

Porvair's patented high-strength HEPA filters can be retrofit into existing installations, ensuring optimum air conditions and a contamination-free environment in many commercial settings. Typical applications include:

High volume commercial and residential

HVAC HEPA filters are an essential part of any overall air quality hygiene regime and are available in self-contained, retrofit and portable HVAC systems.

  • Hospitals, nursing homes, retirement homes, vets
  • Entertainment facilities: cinemas and theatres, event venues
  • Hospitality: restaurant, food preparation facilities
  • Work: large open plan office environments
  • Education: Schools, universities, dormitories
  • Hotels
  • Retail settings: grocery stores, warehouses
  • Waiting rooms
  • Transportation hubs
  • Courtrooms, prisons
  • Military facilities, government offices
  • Religious settings, churches, wedding venues

Industrial HVAC

The purification of the immediate environment in which critical processes are being carried out such as microelectronics fabrication and biopharmaceuticals production.

Nuclear

The removal of radioactive particulate emitted during the vitrification and other containment processes of Nuclear waste thereby preventing contamination of the atmosphere.

Features and Benefits include:

High strength - This patented filter is able to withstand differential pressures much greater than typical glass fiber HEPA filter elements.

Extreme dirt-holding capacity - The filtration media is capable of withstanding high pressure loss (due to high dirt load) before media failure, in both wet and dry environments.

Low pressure loss - Porvair's patented corrugated separators ensure optimal pleat spacing and openness resulting in low differential pressures at high flowrates.

Resistance to flammability - Tested in accordance with UL586, the elements do not contribute to flammability and have a low loss-on-ignition content.

Trevor Waghorn, VP of Sales and Marketing, explained: "This high strength, high flow, range of industrial HEPA filters has been specifically designed in conjunction with the US DOE and a major US EPC firm to handle high exchange rates. The constant circulation and cleansing of the air we breathe should be a critical part of any holistic COVID-19 protection regime."
