AIR FILTRATION MEDIUM WITH IMPROVED DUST LOADING CAPACITY AND IMPROVED RESISTANCE TO HIGH HUMIDITY ENVIRONMENT |
摘要 |
A method for filtering particles from water mist laden air involves passing the air through a medium that has a nanoweb layer in fluid contact with a hydrophobic nonwoven web. The hydrophobic web can be made of an intrinsically hydrophobic material, or can be coated with a hydrophobic coating. The medium does not undergo the large pressure drops normally associated with filtration of water mists and retains its efficiency well. |
