Energy-Efficient Air Solutions
High-Efficiency HVAC Ductwork &
Airflow Control Systems.
Minimize static pressure loss and maximize energy savings. We engineer aerodynamic ducting and smart control units designed to lower Fan Energy Index (FEI) for LEED-certified global projects.
Low-Friction Aerodynamics
Class C Airtightness
SMACNA & ASHRAE Compliant
The Physics of Energy Efficiency.
“Leakage is not just air loss; it is direct financial loss.”
01. Class C Airtightness Standard
Our fabrication process guarantees Eurovent Class C / SMACNA Class 3 airtightness. This reduces fan workload by preventing the escape of conditioned air in high-pressure risers.
02. Aerodynamic Optimization
By utilizing smooth-bore spiral locking seams and long-radius elbows, we reduce the System Static Pressure (ESP), allowing for smaller, more energy-efficient fans.

Technical FAQ
Expert insights on ductwork efficiency, leakage standards, and installation.
How does “Class C” airtightness save money?
Duct leakage forces fans to work harder to deliver the required air volume. By using Class C airtight ducts (which leak 9x less than standard Class A), you can significantly reduce fan speed and power consumption, directly lowering your monthly electricity bills.
What is the advantage of Spiral Duct over Rectangular for energy efficiency?
Spiral ducts have a round profile which offers the least resistance to airflow (aerodynamics). They also have less surface area for heat gain/loss compared to rectangular ducts of the same capacity, making them the most energy-efficient choice for exposed high-velocity systems.
Are your VAV units compatible with BMS systems?
Yes. Our Pressure Independent VAV Terminal Units are equipped with DDC controllers that natively support BACnet and Modbus protocols, ensuring seamless integration with your Building Management System for centralized energy monitoring.
Can you fabricate custom fittings for retrofit projects?
Absolutely. We specialize in custom HVAC fabrication. We can manufacture non-standard transitions, offsets, and plenums to match existing site conditions, ensuring a perfect fit without compromising airflow efficiency.
