Product description

Parameters

The function of the air extractor is to continuously extract the non-condensable gas in the condenser to facilitate the condensation of steam into water. The auxiliary air extractor is also called the start air extractor. It is generally used to extract the air in the condenser and the steam turbine body before the steam turbine starts, and quickly establish a vacuum to shorten the start-up time.
