väliekraan

Väliekraan is a term often encountered in discussions related to ventilation systems, particularly in buildings. It refers to an intermediate screen or filter used within a ventilation duct. The primary purpose of a väliekraan is to capture larger particles of dust, debris, or other airborne contaminants before they reach more sensitive components of the ventilation system, such as fans, coils, or finer filters. This pre-filtration helps to extend the lifespan and maintain the efficiency of these downstream elements.

These intermediate screens are typically made of durable materials like metal mesh or coarse synthetic fibers, designed for easy removal and cleaning or replacement. Their installation can be found in various types of ventilation systems, including those used in residential, commercial, and industrial settings. The effectiveness of a väliekraan is dependent on its mesh size and the airflow rate it is designed to handle. Regular maintenance and inspection of väliekraan are crucial for optimal performance and to prevent potential blockages within the ventilation network. In essence, it serves as a first line of defense in the multi-stage filtration process of many air handling systems.
