ST-Series
Features:
●
High vacuum, high flow rate
ST Series pumps are driven by rotary vane, with high
flow, vacuum can reach over 0.1 Torr. It is suitable for
laboratories that need high/medium volume and
vacuum for experiments.
●
Quiet and low vibration
ST Series pumps feature low noise level, low vibration and
long product life.
●
Thermal protection device
Every motor of ST Series pumps has a built-in thermal
protection device to shut off the pump automatically
when overheated and then restart it when the
temperature cools down.
Applications:
●
Vacuum filtration
●
Vacuum drying
●
Vacuum oven
●
Centrifuge
●
Various vacuum application.
