SFL Series FlowLogic™ Flow Controllers

Most plant air systems have sufficient compressed air capacity. The problem is distributing this capacity where and when it is needed in the system. Peak demands will often exceed capacity. The deficiency is made up by drawing air from the distribution system. To compensate for these demands, the system pressure is increased, leading to significant energy waste.

There is a new paradigm for your compressed air system. Oversupply is not the answer. The answer is delivering the required flow, pressure and level of air quality at the lowest cost--no more, no less.

Sullair FlowLogic Controllers provide a product-based solution in the total air system approach by managing the distribution of compressed air to production. This is done by creating upstream storage and controlling its flow into the plant air system.

Results may include:

  • Stable system pressure (± 1% or better)
  • Reduced energy consumption
  • Improved productivity
  • Fewer complaints

Models vary by region. Please contact your Sullair sales representative for more details.
