When it comes to ducting systems, efficiency is critical. An inefficient ducting system will not only increase energy costs but can also risk non compliance if used for moving harmful pollutants from the workplace. Whether you’re working in commercial HVAC or industrial LEV, one of the quickest wins for improving efficiency comes down to a simple principle: stop air leakage. That’s where sealed ducting makes all the difference.
The Power of Sealed Ducting
In many cases, duct leakage can account for a 20–40% reduction in overall efficiency of heating and cooling systems. For HVAC and ventilation systems this not only wastes fan energy, creates inconsistent temperatures and in LEV systems, potentially dangerous reductions in extraction efficiency. Our range of sealed ducting helps to eliminate air leakages with its double-lipped EDPM sealing gasket providing enhanced protection against leakage. When installed as recommended, the built-in gaskets provide superior air tightness of class D. Furthermore the EDPM rubber gaskets are incredibly durable and can withstand temperatures from -30˚C to +100˚C.
Benefits of sealed ducting for ventilation professionals:
Energy efficiency: Less leakage equals smaller fan loads and reduced kW draw.
Consistent performance: Capture efficiency in LEV and airflow balance in HVAC remain as designed.
Cleaner systems: Sealed ducts reduce the risk of contaminants being drawn in from unconditioned spaces.
Compliance support: For LEV, sealed ducting helps maintain the airflow levels required for COSHH and HSG258 standards.
System longevity: Lower stress on fans, motors, and filters.
Other Practical Steps to Boost Efficiency
Whilst sealed ducting is the backbone of a high-performing system, it’s not the only tool in the kit. HVAC and LEV professionals should also:
- Test and Commission Properly
Airflow verification and pressure testing should confirm that leakage rates are within industry standards. - Maintain Filters and Fans
A blocked filter or struggling fan negates any efficiency gains from sealed ducting. - Balance the System
Proper commissioning ensures supply and extract are aligned, keeping negative or positive pressures where needed.
For ventilation professionals, efficiency is about delivering systems that perform as designed, comply with regulations, and save clients money. Sealed ducting is one of the most effective solutions to achieve that.
