Environmental practical on Respirable dust sampler envirotech APM 460BL


            The APM 460 sampler uses an improved cyclone with sharper cut off ( D 50 at 10 microns ) to separate the coarser particulates from the air stream before filtering it in the glass microfiber filter. By using the APM 460, measurement of Respirable Particulate Matter can be done accurately and TSPM can also be assessed by collection of dust retained in the cyclone cup. 
The particulate matter emitted into the atmosphere from various source is one of the pollution, It is collected through the filter paper with the help of vacuum cleaner type motion fitted high volume sampler. Stock's low offers the basic approach to collection by this technique.


  • Brush-less blower reduces equipment downtime and maintenance effort.
  • Provision of light for the flow and time reading during night.
  • Toolbox within the instrument.
  • Lockable caster, top cover and gaseous attachment.
  • Improved cabinet design which is more sturdy and durable with SS hardware.
  • Electromagnetic Interference ( EMI ) to TVs totally eliminated.
