Abstract
A retention system for use within a molecular sieve unit includes a perforated plate having a top face and bottom face. The perforated plate is configured to be positioned atop a packed sieve bed proximate an outlet end cap of the molecular sieve unit. A skirt is coupled to the bottom face of the perforated plate and a biasing member is configured to engage the outlet end cap and the top face of the perforated plate. The biasing member urges the perforated plate against the packed sieve bed. The biasing member may be one or more wave springs thereby reducing the risk of losing sufficient biasing force against the perforated plate. In the event that a sufficient biasing force is lost, the skirt may operate as a failsafe so as to minimize or prevent tilting of the perforated plate within the housing.
