Oil Mist Trap TM/TMX Series

When an oil rotary pump is started at atmospheric pressure, and operated during low vacuum operation, the pump oil is exhausted along with the exhaust gas that is pumped out. The TM and TMX series oil mist traps help to ensure a clean working environment and protect indoor equipment from contamination that would otherwise be caused by this oil mist.


  • Removes Oil Droplets (“smoke”)
    The amount of pump oil replenishment is greatly reduced
    due to drastic decrease of pump oil consumption by oil
  • Excellent Noise Reduction Effect
    Noise is most effectively reduced when the pump starts
    from atmospheric pressure, during low vacuum pumping,
    and during gas ballast operations. Low frequency noise is
    particularly reduced.
  • Selectable Oil Recovery Method (optional)
    When the oil mist trap is used with trapped oil remaining in
    it, the filter lifespan is decreased and pump problems may
    Recovery method of the trapped oil is dependent on pump
    operating conditions, please consult ULVAC for advice
    about your particular pumping task and to help ensure
    suitable components for your application.
  • Easy Connection to Pump
    Since the connection ports of TM series units are made to
    match standard pump exhaust ports, attachment is easy.
    (An adapter is required when TM-2(F) is attached to VD601
    and VD901)
  • The Internal Filter Element is a Replaceable Cartridge
    Replacing this filter cartridge is easy. (An adapter is
    required when changing filters of old TM-3,4, and 4S
    models to cartridge filters)
    *1 Be sure to use an oil mist trap that is suitable for the pumping speed of the
    pump and the volume of the chamber which is being evacuated.
    *2 An adapter is required for attachment to PVD series, VD151 and VD201.
    *3 Oil recovery cannot be used with TMX-1 and TMX-2 models.
    *4 Conversion to a cartridge filter is not possible for TMX-1, TMX-2, and TM-2
    (old model) units.
