The Challenge: Clients required a High Volume Air Sampler for particulate monitoring which would take accurate samples whatever the wind direction, simplify sample collection, operate quietly and use less power.
The Solution: Lear Siegler Australasia designed and produced the Flowset High Volume Air Sampler for particulate monitoring. A special feature of all models is the unique, variable speed pump controlled by true mass-flow sensing.
The design provides many significant advantages over previous units. Constant air flow is maintained well within 1% of the preset flow rate in conditions ranging from clean filter to more than 80% blockage. There is no need for temperature and pressure corrections and because the motor load is determined by the filter load and not by mechanical restrictions then the consumption of energy is very low.
These High Volume Air Samplers are very quiet running so not to attract attention or annoy neighbours. The vaccum pump has been proven in power stations at full load around the clock for many years and because of the absence of other mechanical or moving parts this helps to eliminate problems found in other high volume particulate monitoring.
Lastly, these High Volume Air Samplers offers user friendly filter collection and replacement for particulate monitoring. No more struggling with fragile tissue on-site in bad weather. The unique removable filter support and transport cover allows filter loading and recovery in a protected laboratory environment without risk of losing the sample.
