AIRSMART™ CONTROL SYSTEM

L11VS – L18VS compressors are easy to use,L11VS – L18VS compressors are easy to use

thanks to the new and advanced AirSmart™h k t th d d d Ai S t

controller. You don’t need to be an expert on

variable speed drives to operate the CompAir

L_VS compressors. The controller takes care

of the details. It auto matically adjusts the

compressor performance to meet your

changing air system demands and saves

your energy costs.

AirSmart™ control system also includesAirSmart™ control system also includes

• Smart energy cost calculationS t t l l ti

• Pressures from 3 to 13 bar

• Integrated sequencing option

• Clear text indicator display

• Multiple languages

• Prevention of reverse rotation

INTEGRATED REFRIGERANT DRYER OPTION

COMMUNICATION AND SEQUENCING

The optional communication module allows the AirSmart™

units to talk to each other. This isn’t just an hour-balancing,

on/off sequencing function. Our controller allows the

system to truly optimize the efficiency because it knows s

the capabilities of the other machines and controls their th

operation. The communication module also allows

remote monitoring of the L_VS and fixed speed units,

providing better energy efficiency in part load operation.p

MAXIMUM FLEXIBILITY

Thanks to the new highly functional AirSmart™ control T

system, the new L11VS – L18VS series allows you to

choose any delivery pressure from 3 to 10 bar orc

from 10 to 13 bar depending on model. Options includefr

the i ntegrated refrigerant dryer, condensate handling

equipment and a wide selection of compressed air filters.e

These options are available to enable you to build aT

complete compressor station for your needs.c

LOW NOISE LEVELL

The sound-engineered enclosure of L11VS – L18VS

absorbs noise effectively. The package is so quiet, that ita

can be installed exactly where it is needed without any

special consideration for noise. This series is simply as

smart design with high quality parts. Quiet fan, segregated s

cooling air flow, plus motor and air end are isolated to

prevent noise transmission.p

SUPERB REGULATION RANGES

Flexibility comes as standard with the L_VS series.

With a 15 – 100% capacity range, the L_VS series features

quick and wide response to air demand changes.

EASY MAINTENANCE

This series has an advanced automatic belt-tensioning

system, which gives the optimal belt-tension in all

conditions. Due to its compact enclosure, the series

requires limited floor space and the installation of the

package is quick and efficient.

The use of high quality compoonents guarantees a long

service life. CompAir has a nettwork

of trained service providers

available whenever required too

ensure your compressor achieeves

the highest level of reliability.
