The Edwards E2M80 is a two-stage, oil-sealed rotary vane vacuum pump engineered for high reliability and performance in various industrial applications.

Key Features:

• Pumping Speed: Offers a nominal pumping speed of 74 m³/h (43.5 CFM) at 50 Hz and 90 m³/h (53 CFM) at 60 Hz.
• Ultimate Vacuum Pressure: Achieves an ultimate total pressure of 1 x 10⁻³ mbar (7.5 x 10⁻⁴ Torr) without gas ballast.
• Water Vapor Handling: Capable of handling water vapor with a maximum pumping rate of up to 300 g/h when using gas ballast.
• Motor Power: Equipped with a 3.0 kW (4.02 hp) motor, supporting robust operation across various tasks.
• Port Connections: Features an ISO40-F inlet flange and a 25mm NPT exhaust flange for standardized and secure attachment to system components.
• Oil Capacity: Requires approximately 3.0 litres (3.15 quarts) of oil to maintain optimal lubrication and performance.
• Noise Level: Operates at a noise level of approximately 70 dB(A), ensuring minimal workplace disturbance.
• Weight: Weighs approximately 102 kg (224 lbs), facilitating integration into different system configurations.

Design and Performance Highlights:

• Positive Pressure Oil Lubrication: Incorporates a well-proven positive pressure oil lubrication system, ensuring correct lubrication in all duty modes and preventing oil starvation under high gas loads.
• Reliable System Protection: Equipped with protection devices to prevent oil and air suck-back into the vacuum system if the pump stops while under vacuum.
• Gas Ballast Facility: Features a gas ballast valve to introduce a suitable gas into the stator during the compression stage, preventing condensation of vapours inside the pump and reducing oil degradation and pump corrosion.
• Low Noise Levels: Maintains Edwards’s reputation for quiet operation with a typical noise level of 70 dB(A).
