When traditional Roots vacuum pumps are still limited by the cumbersome process of "pre vacuuming and starting the front stage pump", Yital has launched the ETR-WEH series Roots vacuum pump - the world's first breakthrough product to achieve "simultaneous starting with the front stage pump under atmospheric pressure", completely overturning the efficiency logic of vacuum operations and injecting unprecedented acceleration energy into industrial production.

In depth analysis of core selling point: What is the strength of synchronous start of atmospheric pressure?

Ultimate time-saving, start working immediately upon startup

Traditional Roots pumps require waiting for the front stage pump to pump the system pressure to a preset threshold (usually 5000pa< Only when the pressure is below 1300pa can it be started, and the size of the cavity is related to the duration of each startup, which seriously affects the production line rhythm. The ETR-WEH series breaks the pressure limit, and the Roots pump and the front stage pump can start synchronously when turned on, without the need for pre pumping waiting. It can enter a stable pumping state within 30 seconds

The single batch operation time can be directly reduced by more than 80%, especially suitable for batch production and continuous operation scenarios (such as semiconductor, vacuum coating, lithium battery drying, chemical distillation, vacuum freeze-drying, vacuum furnace, vacuum reactor vacuum pumping and other processes).

Strong adaptability to working conditions, fearless of harsh environments

For high dust, high steam, and highly corrosive working conditions, the ETR-WEH series optimizes the rotor profile design and sealing structure, which can avoid problems such as rotor jamming and wear even when starting directly at atmospheric pressure. Its air inlet can directly withstand an instantaneous pressure shock of 101325Pa (standard atmospheric pressure), combined with anti fouling coating and anti backflow device

Ensure stable performance under complex working conditions and significantly reduce maintenance frequency.

More optimized energy consumption and direct reduction in operating costs

In traditional processes, the front-end pump requires long-term high load pre pumping, resulting in serious energy waste. The ETR-WEH series uses "synchronous start+intelligent pressure regulation" technology to match the load of the front-end pump and Roots pump in real time, avoiding ineffective energy consumption. The overall operating power consumption of the machine is reduced by 25% -35% compared to traditional models; Simultaneously reducing the number of device starts and stops

Extending the service life of the core components of the pump body (bearings, seals) can save 40% of annual maintenance costs.
