Title: Innovations by James I Grantham
Introduction
James I Grantham is a notable inventor based in Raleigh, NC (US). He has made significant contributions to the field of filtration technology, holding a total of three patents. His work focuses on developing advanced methods and devices for testing and improving filter efficiency.
Latest Patents
One of his latest patents is a scan device and method for testing filters for leaks. This innovative scanner is designed to inspect high-efficiency filters and detect the presence of pin-hole leaks. The scanner features a plurality of funnel members that are movable along guide members and connected by tube members to a monitoring device. This setup allows for the detection of any contaminants contained in gases entrained in the funnel members.
Another significant patent by Grantham relates to disposable filter modules for filtering. This invention offers a solution to the challenges posed by traditional replaceable filter elements in fixed permanent housings. Instead of using plastic bagging techniques, his design allows for easily disposable and incineratable filter modules. These modules can be removed and replaced as integral units while providing complete protection against contaminants from filtered exhaust air. This is particularly useful in environments containing airborne or potentially airborne hazardous materials, such as biological safety cabinets and nuclear facilities. The modules are maintained under negative pressure via a filtered vacuum source at all times while the inlets and outlets are open, ensuring safety and efficiency.
