Vessels and Housings
Bag housings are sometimes called filter vessels. They are top loading with a hinged or threaded lid. A perforated restrainer basket fits inside the shell to support the filter bag under pressure. The plastic ring¹ at the top of the filter bag snaps into a precision groove inside the housing, providing a positive seal to prevent bypass.
The lid is sealed by a gasket which is typically nitrile (buna) or fluorocarbon (Viton®) rubber² depending on your product's temperature and chemistry.
The surface area of the filter bag determines the quantity of contaminants it can capture before it is used up. The pressure drop across the bag will increase when it reaches the end of its life. Each housing has a ¼" NPT port in the lid for a pressure gage.
Our internet prices are for standard single bag housings. Please contact us for flanged, sanitary, multi-bag, ASME code, and other special requirements.
1. For legacy applications we also offer filter bags and housings which use a metal sealing ring sewn into the top of the bag.
2. Gaskets are also available in EDPM/EPR, Teflon® encapsulated EPR, solid Teflon®, and silicone.
