"Compact, High Flow Vacuum Pump with ""ASR"" (Air Saving Regulator) LEM+ series"
Presentation
. Nozzle Ø : 2 ; 2.5 mm
. 2 vacuum levels : 60% et 85%
. Suction flow rate : up to 275 Nl/min
. Integrated pressure regulator (ASR)
. M12 connections

LEM+ Series, compact, high fl ow vacuum pumps, integrate ASR (Air Saving Regulator) technology that allows up to 40% of energy savings. They are designed for gripping porous products or those with a rough surface.

For gripping airtight or semi-airtight products, it is recommended to use the LEMAX+ Series.
Advantages
• Easy implementation: Plug & Play, multiple choices, every type of application.
• Maximum automatic energy savings:
ASR: 40% savings for porous products.
• Compactness: LEM+ vacuum pumps are the most compact on the market.
• Short response times: Possible installation very close to vacuum pads.
• Automatic blow-off: Reduced PLC I/O requirement thanks to the automatic blow-off function (blow-off time configurable from 0 to 10s).
• Dust resistant: Non-clogging through-type silencer.
• Safety: Product gripping is maintained even during power failure.
Air Saving Regulator (ASR)
Whatever the pressure supplied by the compressed air network is, the integrated regulator feeds the venturi at 3,5 bar pressure, which is optimal for its operation.
-No more unnecessary compressed air consumption.
-No external regulator required and thus the risk of inadvertent misadjustment is eliminated.
As for the usual compresses air network pressures (5-è bar), the calculation opposite shows that the achieved economy is 40% on average.
