Fluorescent powders

What are they?

Fluorescent (contrast) powders are designed for leak testing of filter bags and ventilation systems. When the powder is introduced into the filter system, it settles on the leaky spots. The use of powder in combination with a UV lamp allows the detection of even small leaks, which can lead to contamination of the system.


The fluorescent powder is safe to use, it does not dissolve in water. It can be used in almost any industry – the exception may be some food or pharmaceutical sectors, due to different procedures.

Before using a particular color, make sure it is suitable for the case (filtered dusts must emit electromagnetic radiation with a wavelength that contrasts with that of the powder).

Particle characteristics: 90% nominally between 3 and 5 microns.

We offer powders in the most popular colors:

  • green
  • pink
  • yellow
  • orange

The product is sold in 2 kg buckets.


The use of fluorescent powders is a simple yet essential tool for the control of an existing installation, but also for new installations. It helps to prevent failures and unplanned shutdowns. An important aspect of using fluorescent powders is also optimization of energy costs by eliminating unwanted pressure drops caused by air leaks.
