Leak detector

ICT FILTRATION Fluorescent Leak Detection Powder (FLDP) increases the performance and eco-efficiency of industrial filtration installations easily, conveniently, safely, efficiently, economically and in less than five minutes.

Leak detector for filter bags

This is a contrast powder which, when added through one of the filter suction mouths, reaches the filter bags mixed with the product being filtered. This process takes between 3 and 5 minutes. Under ultraviolet (UV) light, the Fluorescent Leak Detection Powder (FLDP) becomes visible at any emission points where there are leaks. The high-visibility fluorescence of the powder highlights even small leaks. It also makes it possible to locate any leaks that might have occurred in joints, gaskets or cracks in welds.


  • Minimises production shutdowns.
  • Checks the operation of the installation and detects any leak in five minutes.
  • Shows which bag needs replacing and allows the rest to continue in operation.
  • In new installations, a preventive check will avoid any surprises when production starts up.
  • In working installations, regular checks detect any defective bags that need replacing to keep the installation’s safety, performance and eco-efficiency at 100%.
