Rotary pump & chiller acoustic boxes overview

Effective noise reduction for rotary vacuum pumps and water chillers

silentLab acoustic enclosures are especially designed to reduce the noise level generated by vacuum pumps and water chillers used with SEMs, TEMs, FIB-SEMs, sample preparation instruments and other analytical systems.

If it is not possible to locate vacuum pumps and/or the water chiller to a separate room, the noise level generated can be irritating and distracting. Using a silentLab acoustic enclosure will significantly reduce noise to an acceptable level and allow operators to concentrate on the task at hand. silentLab acoustic enclosures are sophisticated and safe soundproofing boxes which are placed over the noisy vacuum pump or water chiller. They facilitate power and vacuum pumping lines, provide cooling and will allow vacuum pumps or water chillers operate at their full specifications.

silentLab models 4, 6 and 7 were originally designed for SEMs, TEMs and FIB-SEM systems, but they are equally useful for other systems with noisy rotary vacuum pumps. silentLab 3 has been specifically designed for smaller pumps used with SEM sputter coaters, EM carbon coaters, RF plasma etcher/asher/cleaners and vacuum ovens. silentLab 5 is intended for analytical systems with larger noisy rotary vacuum pumps.

 silentLab noise reduction enclosures features:

    • Noise reduction approximately 15dB to 12dB, depending on type
    • Robust all-metal construction with high performance acoustic foam
    • Acoustic foam with optimised pattern to reduce low frequency noise
    • IEC mains connectors with fuse for easy installation
    • Fans are only switched on when the rotary pump is running
    • Sophisticated air flow system with low noise high capacity fans
    • Integrated digital thermometer
    • Top lid for easy service access
    • Powder-coated oil and water resistant surface
    • Flammability rating to DIN 75200 / FMVSS 302
    • Internal KF25 installation kit included
