The CFT Series traps are an effective design, which reduces mechanical pump backstreaming to the vacuum chamber. The activated OFHC® copper media is held in place by stainless steel screens which are recessed to allow maximum conductance while accomplishing high trapping effectiveness. Using CFT Series traps will result in a cleaner system that will ensure longer operation cycles before service is necessary. CFT traps need no bakeouts or cooling and are maintenance free. Stainless steel media can be provided by adding "-SS" to the suffix of the part number at no additional cost.
