TRR two-stage series Roots vacuum pump Roots blower

This series of products includes two-stage series Roots blowers and two-stage series wet Roots vacuum pumps.
Due to factors such as efficiency and temperature rise, the pressure ratio of a single-stage blower (vacuum pump) is generally limited to 2.2. In order to achieve a higher pressure ratio, two blowers (vacuum pumps) are usually connected in series to form a two-stage series blower (vacuum pump). Among them, the two-stage series Roots blower is equipped with an intermediate cooler between the two stages.
