Large scale industrial painting processes can produce dangerous fumes. Depending on the type of paint being used, there are a number of potentially harmful substances known as volatile organic compounds or VOCs. These can be up to 10 times more concentrated indoors than outdoors and bring a wide variety of both short and long term negative health effects. Fume extraction systems are specifically designed to capture these compounds to prevent harmful exposure to people and damage to the environment. InterApp’s resilient seated butterfly valve technology is ideal for use within dust & fume extraction systems. Please note: from May,2018, you can find J-PECO valve inspection service in Valve World Buyer's Guide+Oneline.
