Molecular Sieve Traps Molecular Sieve Traps Description TLI's molecular sieve traps utilize synthetic zeolite with a high surface area per unit volume. Its design insures effective trapping of hydrocarbons and water vapor, as well as preventing backsteaming of mechanical roughing pump oil. The molecular sieve trap operates at room temperature, thereby eliminating the necessity of any refrigerants. A built-in heater reprocesses the sieve material when necessary at a bakeout temperature of 375°C. Specifications TLI molecular sieve traps are fabricated of type 304 stainless steel. An internal screen assembly serves to contain the sieve material, preventing it from entering other areas of the vacuum system. Baffles are arranged around the sieve container to insure the passage of all molecules into the sieve material area. Inlet and outlet ports are available either 180° apart inline (or 90° apart right angles) with or without flanges. Mech.
