Casella has launched its new Apex2 range of personal air sampling pumps, using maxon’s DC motors, to monitor the personal exposure to dust, fumes and vapours in high-risk occupational sectors and to safeguard the future health of workers against serious respiratory disease.

Air sampling pumps are used to collect a dust or vapour sample in a working environment. The Apex2 personal pump is a small, robust appliance that an individual wears on the body. It draws air through a filter, or sorbent tube, where the hazardous substances are deposited. 

The filters, or tubes, are then processed in a lab to determine the levels. An occupational hygienist will be able to calculate the level of exposure to the individual using data from the pump, such as the flow rate and the volume of air drawn through the filter, or sorbent tube, and the amount of hazardous substance from the lab results. Companies can use this data to ensure their workers are operating within the exposure limits for that particular substance.

Global organisation Casella approached three companies in the UK to supply sample motors for the Apex2 personal sampling pump, maxon motor uk being one of them. The maxon A-max 22 brushed DC motor was chosen due to the high efficiency and low current, in comparison to the others. 

Key benefits of product application

  • The efficiency of the motor at a working load means less power is required and, as the pump is battery operated, the battery life is prolonged (>45 hours).  This results in extended run time of the product, i.e. the pump will run for an entire shift without recharging.
  • The low inductance of maxon motors helps mitigate low spark ignition, so they don’t ignite gases or dust.
  •  maxon’s added value service included a strip down and inspection after a set amount of running hours and a comprehensive report was produced. This included photographs of the worn motor components after testing. From this report the company was able to estimate how many more running hours were achievable.
