Roof exhaust fans — weather-tight extraction above the roofline

Roof-mounted extractors ventilate warehouses, kitchens, plant rooms, and commercial buildings without consuming floor space. Sri Venkateshwara Air System in Bangalore supplies and installs roof exhaust units with curb bases, flashings, and connections coordinated to your duct riser and structural loads.

Roof exhaust fans (roof extractors) mount on the building roof and discharge hot, stale, or contaminated air above the weather line. They are common in industrial halls, commercial kitchens, parking ventilation stacks, and mechanical rooms where vertical discharge is preferred.

Typical applications

  • General building exhaust and heat relief
  • Kitchen and grease exhaust risers (where design allows roof termination)
  • Plant and warehouse ventilation
  • Toilet and light commercial exhaust manifolds

What we coordinate on site

Curb and roof interface: Matching the unit base to roof sheet profile, curb size, and waterproofing details.

Duct connection: Rigid or flexible connections from the vertical riser, access for cleaning where required.

Electrical: Motor voltage, starters, and speed control aligned with your panel and BMS points.

Duty selection: Airflow and static pressure matched to your system — including allowance for filters, louvers, and weather caps.

Why work with us

We fabricate and install related ductwork and supports in-house, so roof units arrive as part of a coordinated package rather than an isolated purchase. Share your consultant’s schedule or a site survey brief and we can propose sizes, curb drawings, and installation scope.
