The easy to install, rugged 2504-A allows for higher vacuum levels and provides better internal corrosion protection and longer life. Its internal sound suppression results in lower operating noise levels, which makes it well suited for noise sensitive environments like laboratory applications. In addition, this compact unit offers high flow, pulse free air making it ideal for applications requiring consistent air pressure and air flow.
