Compressed Air Controller
Manage up to 12 compressors

The CompAir SmartAir Master compressed air controller, can intelligently control up to 12 compressors of any combination (fixed or variable speed) and will reduce energy consumption. This is achieved by tightening the network pressure to the smallest possible band, keeping off load running to the absolute minimum.

Demand responsive operation ensures that where varying capacity compressors are installed, only the correct combination of compressors are selected to meet the system demand, resulting in maximum energy savings.

Where compressors of the same capacity are installed, the compressed air controller sequencer will equalize the running hours, offering even greater savings by optimising the service intervals.

Key Benefits

  • Maximised energy & cost savings
    By reducing off-load times to a minimum and operating all the system compressors to the narrowest pressure band, maximum energy and cost savings can be achieved.
  • Transparent & flexible operation
    This compressed air controller features an extremely user friendly and fully self explanatory large colour graphics, touch screen display which provides a quick overview of the compressed air supply and connected compressors at any time as well as; network pressure, pressure range and compressed air consumption, individual status display of each compressor connected, fault and warning messages and much more!
  • Simple to install
    With low cabling costs and using a data cable with a “bus structure”, the CompAir SmartAir Master compressed air controller is simple to install.
  • Complete compressed air system controller
    For a complete compressed air system controller, accessories such as dryers, filters and condensate drains can be easily connected to the CompAir SmartAir Master, either directly or to an extension module.
