Ducting & Air Distribution
(Engineered air conveyance and distribution systems for performance, balance & comfort)
Engineered Airflow Delivery from Source to Space
Ducting and air distribution systems form the physical backbone of any HVAC installation, responsible for conveying conditioned air from air handling equipment to occupied spaces with minimal losses and balanced airflow. Proper duct engineering directly affects system efficiency, noise levels, indoor comfort, and energy consumption.
At Compress India, ducting and air distribution are treated as engineering systems, not fabrication-only activities. Our designs focus on correct sizing, pressure loss control, airflow balancing, acoustic performance, and seamless integration with air handling and ventilation equipment.

What are the different types of ducting materials available?
Common ducting materials include GI (galvanized iron), MS (mild steel), SS (stainless steel), aluminium, pre-insulated PIR/PUF ducts, and fabric/flexible ducts. Selection depends on application, environmental conditions, and hygiene requirements.
How is duct sizing determined for HVAC systems?
Duct sizing is based on airflow requirements (CFM), velocity limits, pressure drop calculations, acoustic considerations, and space constraints using methods like equal friction, velocity reduction, or static regain.
What is air balancing and why is it important?
Air balancing adjusts airflow distribution to ensure each space receives designed airflow. It's crucial for system efficiency, comfort, energy savings, and preventing hot/cold spots.
What are the key factors in duct layout design?
Key factors include shortest practical route, minimum bends/transitions, access for maintenance/cleaning, coordination with other services, structural support, fire/smoke containment, and acoustic considerations.
How do I control noise in ducting systems?
Noise control involves proper duct sizing (velocity limits), acoustic lining, vibration isolation, flexible connectors, sound attenuators, proper fan selection, and avoiding abrupt transitions.
What maintenance is required for ducting systems?
Regular maintenance includes visual inspections, cleaning (especially for hygiene-critical applications), checking insulation integrity, verifying damper operation, ensuring proper sealing, and monitoring pressure drops.
What are fire dampers and smoke dampers?
Fire dampers close during fires to prevent flame spread through ducts. Smoke dampers control smoke movement. Both are critical for compartmentation and life safety, required by building codes.
What is the difference between supply and return ducting?
Supply ducts deliver conditioned air to spaces, typically under positive pressure. Return ducts collect air from spaces and return it to the HVAC unit, typically under negative pressure. Sizing and design considerations differ.
How does duct insulation affect system performance?
Proper insulation prevents thermal losses/gains, controls condensation (especially in cooling applications), reduces noise transmission, improves energy efficiency, and maintains desired air temperatures.
What are the standards for ducting fabrication and installation?
Key standards include SMACNA for fabrication/installation, ASHRAE for design, NFPA 90A/90B for fire safety, ISHRAE guidelines, and local building codes. Cleanroom applications follow more stringent standards.
How long do ducting systems typically last?
With proper design and maintenance, GI/MS ducts typically last 20-30 years, stainless steel 30+ years. Factors affecting lifespan include environmental conditions, maintenance, air quality, and operational hours.
What are common ducting system problems and solutions?
Common problems include inadequate airflow (undersized ducts), noise (high velocity/poor design), leaks (poor sealing), condensation (insufficient insulation), and imbalance (improper design/installation). Solutions involve proper design, quality installation, and regular maintenance.
