Oferecendo alta confiabilidade, baixo custo de vida útil e desempenho comprovado, a série de estágio único nES da Edwards representa o novo avanço nas bombas de vácuo de palhetas rotativas seladas e lubrificadas a óleo para utilização em uma ampla faixa de mercados e aplicações.
O sistema otimizado de retorno e separação de óleo auxilia no desempenho estável da bomba e minimiza a perda de óleo.
Motores com refrigeração eficiente, retenção de óleo otimizada, baixas temperaturas da bomba, alta confiabilidade e manutenção mínima fornecem um custo de vida útil excelente em comparação com outras bombas de palhetas rotativas de estágio único.
