Effectively blocks backstreaming by absorbing hydrocarbons
Traps water vapor
Regeneration using built-in heater
Type 304 stainless steel trap body
Available in five connection sizes ISO KF and LF ports
Molecular Sieve Traps containing Type 13X synthetic zeolite effectively prevent oil backstreaming at room temperature. They also trap water vapor in the sieve charge. The sieve charge can be
reactivated by baking out in place when the base vacuum cannot
be achieved. A valve should be used to isolate evolved gas from
the system during bakeout cycle. During the bakeout the mechanical
pump removes the evolved gas from the sieve trapping material.
Normal bakeout can be accomplished by use of a timer during
Any oils trapped by the sieve material cannot be removed by baking.
Periodic replacement is required whenever the sieve material
exhibits evidence of hydrocarbon loading as determined by empirical
observation. Sieve trapping material can be replaced through
port on top of trap. Traps can be mounted in the standard vertical
or horizontal position.
The built-in heater requires wiring to a 115VAC wall outlet. Once
turned on, the heater reaches and maintains a self-regulated constant
150ºC temperature. Bakeout time depends on the amount of
water vapor loading of the zeolite, within the range of 4 to 12
