In any kitchen extract system, maintaining proper airflow is critical for both safety and efficiency. One often overlooked component is the mesh terminal grill, which plays a vital role in ensuring air exits the system smoothly. However, when these grills become clogged due to grease, dust and debris, they can cause severe operational issues. In this article we will explore why cleaning mesh grills in extract systems is an essential part of the system maintenance.
Why Cleaning Mesh Terminal Grills is Essential
Over time, mesh terminal grills in kitchen extract systems accumulate contaminants that restrict airflow. This blockage not only reduces system efficiency but also poses a serious fire risk. According to NAAD21 Regulations, regular maintenance and cleaning of extraction systems are required to ensure compliance with fire safety and air quality standards.
The Consequences of Neglecting Mesh Terminal Grill Cleaning
If mesh terminal grills are not properly cleaned or replaced, the system begins to experience restricted airflow, leading to several operational problems:
- System Blockage: A clogged grill prevents air from escaping, causing a pressure build-up within the extract system.
- Backdraft Issues: Instead of moving outward, air can be forced back down through the system, known as a backdraft. This can reintroduce grease, smoke and contaminants into the kitchen, impacting air quality.
- Extraction Fan Motor Failure: The backdraft places additional strain on the extraction fan motor, leading to overheating and ultimately, system failure. Replacing a burnt-out motor can be costly and result in downtime for the kitchen.
How Rope Access Ductwork Specialists Ensure Proper Maintenance
Accessing and maintaining mesh terminal grills can be challenging, especially in high-rise buildings or hard to reach areas with limited accessibility. Our expert rope access ductwork teams specialise in:
- Deep cleaning mesh terminal grills to restore full airflow.
- Replacing grills when cleaning is not possible, which releases air pressure and prevents system blockages.
- Ensuring compliance with NAAD21 Regulations, guaranteeing your extract system meets fire safety and air quality standards.
Replacing the Exit Grill to Prevent Airflow Restrictions
In cases where the mesh terminal grill is beyond cleaning, replacing it becomes necessary. A new, clean grill releases the built-up air pressure, preventing backdraft and ensuring the extraction fan operates efficiently. This simple yet crucial step can prevent costly damage and extend the lifespan of your extract system.
Key Facts
- Regular cleaning of mesh terminal grills is essential for maintaining proper airflow and system efficiency.
- Blocked grills cause backdraft, leading to air pressure build-up and extraction fan motor burnout.
- Rope access ductwork cleaning allows safe and effective maintenance of hard-to-reach terminal grills.
- Replacing clogged grills restores airflow and prevents long-term damage to the extract system.
- Compliance with UK Regulations is mandatory to ensure fire safety and avoid regulatory penalties.
