These In-Line Molecular Sieve Traps perform a dual function. A zeolite molecular sieve, grade 13X, desiccant removes hydrocarbons (mechanical pump oils) which back-stream toward the chamber. Also, the molecular sieve traps water vapor and other condensable gases before they reach the mechanical pump and contaminate the pump oil. All molecular sieve traps are supplied with a molecular sieve charge and a regeneration heater.
Note on Quantity:
The 4-inch body OD traps require 0.75 # of molecular sieve; the 6-inch body OD traps require 1.5 # of molecular sieve and the 8-inch body OD traps require 4.75 # of molecular sieve.
