FRP Ventilation Duct

FRP Ventilation Duct

The Jinyang FRP (Fiberglass Reinforced Plastic) ventilation duct is a corrosion-resistant ducting system designed to carry corrosive exhaust, fumes, and industrial air. With a smooth, non-porous interior and lightweight construction, it resists acid mist, chemical vapors, and moisture for long-term ventilation in polluted or aggressive environments.

How It Works

The duct is filament-wound or hand-laminated from FRP to a circular or rectangular cross-section. Exhaust air is drawn through the duct by fans and routed to scrubbers or discharge stacks. The sealed, corrosion-resistant walls contain fumes without rusting, and flanged sections bolt together to form long runs.

Key Features

• Corrosion resistant - resists acid mist, alkaline vapors, and chemical fumes that destroy galvanized steel ducting.

• Smooth interior - low air resistance and easy cleaning, no dust build-up.

• Light weight - easy to rig and install overhead without heavy support steel.

• Airtight joints - flanged or socketed connections prevent fume leakage into work areas.

• Fire-retardant option - flame-retardant resin available for HVAC and exhaust applications.

• Long service life - no painting or external corrosion protection required.

Technical Options

Round or rectangular sections, diameters 100-3000 mm, with polyester or vinyl ester resin. Bends, tees, reducers, dampers, and access doors available; fire-retardant and anti-static options on request.

Typical Applications

Chemical plant exhaust, laboratory fume extraction, scrubber ducting, plating lines, wastewater odor control, and industrial ventilation.
