Frequently Asked Questions

A transparent automatic drain allows real-time visual monitoring of condensate discharge in a compressed air system.

Unlike conventional drains, it provides immediate visual control without disassembly or technical intervention. This allows you to :

  •  verify proper system operation
  •  quickly detect an anomaly
  •  identify the presence of water, oil, or contaminants

It is an ideal solution to improve preventive maintenance and system monitoring.

Le drain transparent est particulièrement adapté aux installations où la visibilité et le contrôle sont essentiels.

Il est recommandé pour :

  • les laboratoires et environnements propres
  • les installations nécessitant une surveillance régulière
  • les systèmes d’air comprimé de petite à moyenne taille
  • les applications pédagogiques ou de démonstration

Il est idéal lorsque l’on souhaite contrôler rapidement et facilement le fonctionnement du drain.

The transparent automatic drain operates on a simple principle :

  1.  Condensates (water, oil, and particles) accumulate in the body of the drain.
  2.  An internal mechanism automatically triggers the discharge.
  3.  Condensates are discharged outside.
  4. The user can directly observe the process thanks to the transparent body.

This operation ensures autonomous condensate management with continuous visual monitoring.

A transparent drain is recommended when :

  •  when visibility of operation is essential
  •  when maintenance needs to be simplified
  •  when the environment is clean
  •  when the need for extreme precision or robustness is limited

However :

  • a float drain is better suited for contaminated environments
  • an electronic drain allows for precise adjustment
  • a stainless steel drain is recommended for corrosive environments

👉 The choice always depends on your application and operating environment.
