Pumps for Dust and Pollution Measurement or IAQM

Charles Austen Pumps have been designing pumps for air quality monitoring since the practice began with the national survey in the 1960’s as a response to the infamous London ‘pea souper’ smog’s.

Since then as the impact of airborne pollution on health and well-being has become clearer, the use of volumetric or Iso-kinetic air sampling has become more necessary, including the sampling of PM 2.5- PM10 particulate levels in the air as well as traditional concerns such as asbestos.

This has led to a demand for more flexible sampling pumps that can be easily adjusted to meet a range of worldwide sampling standards including EN12919, ISO-9096, EN13284, EN 16911 & EPA 201A.

Charles Austen Pumps have continued to develop our pump range to help our customers meet these challenges thanks to the addition of the CAPEX V2 Duplex Pump to our CAPEX range.

We are able to supply single and dual headed CAPEX Pumps for sample aspiration with flow rates from 8 l/pm – 32 l/pm (480 to 1920 l/ph), while still offering a range of motor options including low current draw DC BLDC specification for portable battery powered applications.

All CAPEX pumps include an exhaust port for connection to a flow rate/mass sensor which allows downstream control of the flow rate via a sampling filter. This helps to maintain much-needed accuracy in sampling results.
