Features

	The two-stage exhaust system has lower pressure (good vacuum) than the one-stage exhaust system.
	Low noise and low vibration.
	The backflow prevention mechanism prevents oil from flowing back to the vacuum chamber when it is stopped due to a power failure.
	The exhaust speed is stable due to the installation of the forced oil supply mechanism.
	Operation from atmospheric pressure is possible.
	Easy connection by internal components knock pins and maintenance by flange motor.

Applications

	Chemical, science experiment, Analyzer and Laser system.
	Backing pumps for the electronic microscope.
	Semiconductor, sputtering and vacuum evaporation equipment.
	Vacuum dryer, freeze dryer.
