Air leak detection in compressed air

Reduce the energy costs of your compressed air system with an air leak detection audit from BCAS.

All compressed air systems have leaks. The average leakage rate of is approximately 25% but some plants lose as much as 80% of their compressed air due to leaks.


While it may not be practical to eliminate all leaks, it is not difficult to greatly reduce and minimise them. The percentage lost to leakage should be less than 10% of your total compressed air production. A well-maintained system with a proactive leak detection programme in place should allow you to achieve this.

Detect, repair, save.

BCAS engineers use the latest ultrasonic testing equipment to identify and quantify all air leaks, many of which are imperceptible to the human ear.


Once a system has been logged and leaks have been tagged, a detailed report is produced outlining the extent of the losses and the recommended works.


And if you wish, BCAS can then carry out the necessary leak repairs. In fact, BCAS can manage the entire process for you and can even incorporate it into an overall energy efficiency programme for your compressed air system.
