Large-Scale Ducting & Exhaust Design

Engineered Airflow for Massive Spaces.

Proper ventilation is critical for factory safety and comfort. We provide airflow balancing, static pressure diagnostics, and duct modification for large-scale AHU systems, fresh air intakes, and toxic exhaust extraction networks.

Technical Capabilities
  • Static Pressure & Friction Loss Calculations
  • Anemometer Airflow Balancing (CFM/Velocity)
  • Motorized Damper Actuator Servicing
  • Canvas/Flexible Joint Replacements
Industrial SLA

We operate across Chakan, Ranjangaon, and Wagholi MIDCs with 4-hour response times for critical manufacturing plant breakdowns.

Fault Code Library

Common Large-Scale Ducting & Exhaust Design error codes and our diagnostic response protocols.

AHU / Exhaust Standards

Low Static Pressure

Duct leakage or slipping fan belts

Action:Perform smoke test for leaks; tighten blower belts.

High Static Pressure

Clogged filters or closed fire dampers

Action:Check secondary filters and VCD/FD damper positions.

Preventive Maintenance

Our standardized operating procedures (SOPs) for routine maintenance.

  1. Measure total external static pressure (TESP) across the blower.
  2. Inspect canvas connections for tears or air leaks.
  3. Verify all Volume Control Dampers (VCDs) are locked in their balanced positions.
  4. Check exhaust fan motor bearings for vibration using diagnostic tools.
Case Study Highlight

Frequently Asked Questions

Q. Why is the airflow weak at the end of the duct run?

This is usually caused by excessive friction loss, poor duct transition design, or uncalibrated dampers diverting air too early.

Q. What is the standard velocity for industrial exhaust?

It varies by application. Fumes require ~2000 FPM, while heavy dust extraction may require 4000+ FPM to prevent settling.
