Bơm chân không cánh gạt một cấp kiểu liền trục SERIES EM 4-8

EM 4 – 8

Áp suất chân không max: ≤ 2 and ≤ 20 mbar
Lưu lượng: 4÷10 m3/h

The EM 4 and EM 8 are single-stage rotary vane lubricated pumps with oil recirculation.
The rotor is keyed directly onto the motor shaft.
The oil tank is provided with a system for separating the oil mists from the exhaust air.

The gas ballast, except for EM4, prevents condensation inside the pump when small quantities of steam are sucked.

The EM 4 and EM 8 pumps are suitable for the evacuation of closed systems or to operate at a constant vacuum included in the following range:

EM 4 – EM 8 from 2 to 300 mbar (absolute)

EM 4 B – EM 8 B from 20 to 850 mbar (absolute)
