G-Series bag-in/bag-out filter housing allows a single filter element (prefilter, HEPA filter or gas adsorber) to be installed in a low CFM ventilation system. These filter housings are designed for particulate filtration and gas filtration. The G-Series design is built so that the housing can be tested in place and is flexible, accommodating various arrangements of inlet and outlet ports to fit particular applications.
One of the primary uses of HEPA filters is to contain toxic materials. When filters become contaminated with these materials, it is important that there is a method for the filters’ removal without direct operator contact. The bag-in/bag-out feature of the G-Series filter housing allows an operator to change filters without coming into direct contact with the collected toxic materials, including viable organisms, radioactive dust, and carcinogens. Air is supplied to and exhausted from the G-Series filter housing through round inlets and outlets that are connected to the operator’s pipe or ducting.
G-Series filter housing is designed for single filter replacement from the top of the unit. This filter housing can be installed through side access, but it is not recommended that the unit be supported by inlet and outlet connections. Instead, a mounting stand or some other means of support should be used.
There is no specific diameter for the inlet and outlet connections on the G-Series filter housing, since requirements vary considerably. The purchaser or system designer can simply specify the required pipe (or tubing) sizes and lengths. The G-Series inlet and outlet connections can be a standard rolled stainless steel sheet metal nipple or optional stainless steel piping.
The filter-to-housing fluid seal is created between the housing and the filter by means of a continuous knife edge in the housing. This knife edge mates into a channel on the upstream (air entering) side of the filter, which is filled with a highly viscous non-drying sealing compound. The knife edge seal is guaranteed to pass an in-place DOP test.
