Edwards Silencer for XDS35i Dry Scroll PumpFeatures - Compact design combines both filtration effici (more)ency and noise reduction - Integrated inlet diffuser optimizes sound attenuation - Multi-stage noise reducing features including final stage sound absorbent insert - Tubular silencing design - tube is positions to maximize attenuation and air flow while minimizing pressure drop - Patented high grade element with built-in butterfly gasket seal which creates positive seal between housing hemispheres and a new seal with each element - Seamless drawn housings - no welds to rust or vibrate apart - Durable carbon steel construction with black powder coated finish - Ability to mount vertically or horizontally The Edwards Silencer for XDS35i Dry Scroll Pump has two main functions: to reduce exhaust noise during pump down and gas ballast operation as well as to collect and retain tip seal dust as the pump is operated. Exhaust gases exit the exhaust port when the pump is being used to evacuate a process chamber, or when the gas ballast control is being used, or both. The noise level when pumping down rises as the throughput increases and the silencer is used to reduce this noise level. The outer can is made of pressed steel and is split to allow access to the filter elements. The filter element housing is made from Santoprene thermoplastic elastomer. The element itself is polyester. The foam block is manufactured from filter foam. INCLUDED: The Edwards Silencer for XDS35i Dry Scroll Pump includes: - NW25 Clamp - Centring Ring - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
