COVAL Energy Saving Solutions al ps iti o n p u m Trad uum Vac (ASR): Porous Applications The LEM+ and LEMAX+ vacuum pumps, which integrate an ASR “venturi regulator” combination, share values that COVAL values greatly: they greatly reduce the volume of compressed air consumption and noise level. 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...

LEM+ / LEMAX+: Implementation Mountings and Connections 1- Mounting from side Version: one M12 connector Mounting from side is the simplest to implement: Two Ø 5 mm through screws or bolts with large washers. 3/8"BSP 2- Mounting from front For mounting from front, in addition to the module, you need to order an additional kit: Individual installation plate with 4 mounting screws Mounting from front kit: 1 plate + 4 screws For a static mounting (for example, in a cabinet), a module can be clipped onto a DIN rail. For this purpose, the module must first be equipped with an individual plate...

Reminder: LEM+ modules are adapted for gripping all porous or airtight products. If you handle mostly airtight products, the LEMAX+ (ASC) modules will enable you to achieve remarkable air economy. VACUUM LEVEL NOZZLE DIAMETER 1- Maximum Vacuum Level It depends on the mixer profile: - 85% of maximum vacuum is optimal for gripping airtight products. - 60% of maximum vacuum is optimal for gripping porous products. 2- Nozzle Diameter It reflects the generated vacuum flow rate, as well as the power consumed. Therefore, it must be selected to meet the right requirements, without excess. Handling...

SPECIFICATIONS ■ Threaded female connectors. ■ PVC covered cable. ■ IP65 protection. Part Number LEM / LEMAX: 2 Complementary Series LEM+ and LEMAX+ meet the “high capacity flow rates” needs of installations. They complement the LEM and LEMAX series provided for average flow rates. 11 LEM Series Designed for any gripping: ■ Porous products: cardboard, coated wood, pastries, etc. ■ Airtight products, when LEMAX is not feasible. LEMAX Series Designed for gripping airtight products: ■ “ASC” self-regulation saves from 60 to 99% of energy without any operating constraints. vacuum managers
