Compact, High Flow Vacuum Pump with ASR (Air Saving Regulator) LEM+ series

Technical Specifications

• Nozzle Diameters: 2 ; 2.5 mm
• 2 Vacuum Levels: 60% and 85%
• Suction Flow Rate: up to 275 Nl/min
• Integrated pressure regulator (ASR)
• M12 connections

The LEM+series, compact and high-flow vacuum pumps, integrate ASR (Air Saving Regulator) technology, providing up to 40% energy savings. They are specially designed for gripping products with porous or rough surfaces. The LEMAX+ Series is recommended for gripping airtight or semi-airtight products.

Advantages

• Easy application: Plug & Play feature, multiple options, suitable for every type of application
• Maximum automatic energy savings: Up to 40% savings on porous products with ASR
• Compactness: The LEM+ series is among the most compact vacuum pumps on the market
• Short response time: Allows installation very close to suction cups
• Automatic blow-off: Adjustable (0–10 s), reducing PLC input/output requirement
• Dust resistance: Non-clogging flow-through silencer
• Safety: The product remains gripped even if power is cut

ASR – Air Saving Regulator

Regardless of the pressure coming from the compressed air network, the integrated regulator supplies the Venturi with a constant 3.5 bar—which is the optimal operating pressure.

• Unnecessary air consumption is prevented
• No need for an external regulator, eliminating the risk of incorrect adjustment
• An average of 40% savings is achieved considering network pressure (5–7 bar)
