Coval´s new LEMAX IO series of mini vacuum pumps with IO LINK communication integrate all the required
functions for optimized vacuum management in a compact package. Via their IO-Link communications
interface, the mini vacuum pumps communicate permanently with the environment and thanks to ASC (Air
Saving Control) technology, combine productivity with energy savings, adapting to a multitude of applications
in packaging, robotics or plastics processing. Without needing extra peripherals, these all-in-one mini pumps
are fully compatible with Industry 4.0 automation.

IO-Link, simplified communication
The IO-Link interface ensures efficient real-time communication between LEMAX IO vacuum pumps and all
the higher-level protocols (Ethernet/IP, PROFINET, EtherCAT, etc.) used for supervising the production line.
IO-Link enables continuous diagnostics, centralized programming and pump control. The availability of realtime
diagnostic status data makes it possible to optimize production. In addition to fast and cost-effective
installation, preventive maintenance is easier and the replacement of vacuum pumps does not require
reconfiguration.

Energy savings
ASC technology, which ensures intelligent vacuum control by stopping air consumption when the set vacuum
level is reached, generates energy savings of between 75 and 99% depending on the application. In
addition, ASC analyses the application and adapts to either impermeable or porous parts to optimize
operation and energy consumption.

Compact size and light weight
Compact in size, the LEMAX IO pumps have all the principal functions integrated in a single module:
pressure regulation, solenoid valves, anti-clogging open silencer, electronic vacuum switch, M8 connector
(direct Plug & Play connection) and adjustable blowing. Their reduced size and weight (130 g) allow the
suction cups to be positioned at minimum distance to achieve the shortest possible grip time without load
loss.

Modularity
The LEMAX IO can be adjusted to the needs of integrators and users. They are available in three nozzle
diameters (1, 1.2, 1.4 mm) allowing a suction flow rate from 29 to 70 Nl/min (max. vacuum 85%). They are
optionally equipped with a normally closed (NC) or normally open (NO) solenoid valve. This variant is
recommended for applications where gripping the workpiece must be guaranteed in case of an unexpected
power failure, or even if leakage occurs (positive safety).

Several LEMAX IOs can be combined in an island with a single pressure supply.
