Acoustic Enclosure Reduces Noise Level by up to Seven Decibels
May 07 2010
Edwards has launched a new competitively priced acoustic enclosure for its popular EM and RV rotary vane pumps. The enclosure reduces the noise level of each pump by up to seven dBA, enabling scientists to
work in a significantly quieter environment.
The enclosure incorporates an acoustic foam lining to reduce noise and has been designed to ensure sound is dissipated efficiently. The new enclosure houses any Edwards EM and RV pump ranging up to the E2M28 series and is fully compatible with Edwards inlet traps and exhaust mist filters when these are fitted with extension spools.
The compact enclosure is assembled or disassembled simply, without tooling, which makes the pump easy to access. A removable front panel enables quick access to the oil sight glass and if required, a side panel can be removed to allow access to the oil filler cap. Oil can be drained without having to remove the pump. The enclosure has castor wheels and brakes for easy manoeuvring.
It features integrated cooling fans to maintain the optimum pump running temperature and has an over-temperature buzzer alarm with battery back-up, so customers can ensure their pump is run in a benign environment.
“Individually the pumps are quiet. However, in a laboratory containing many vacuum pumps, the noise level can often become quite noticeable and distracting,” said David Goodwin, Product Manager Scientific Pumping, Edwards. “We previewed a prototype acoustic enclosure at the American Society for Mass Spectrometry’s conference last year and received lots of positive customer feed back. This has contributed to the refinement of the design we are bringing to the market today.”
