Product Overview
PVC Exhaust Ventilation Duct is engineered for industrial and commercial air extraction systems requiring flexible routing, stable airflow, and moisture resistance.
Manufactured with reinforced PVC and a continuous spiral steel wire core, this ducting efficiently exhausts smoke, fumes, dust, odors, and contaminated air from localized working environments.
Compared to rigid metal ducting, it offers easier installation, lighter handling, and superior flexibility for movable or temporary connections between ventilation equipment and extraction points.

Performance Advantages
Stable Airflow Under Pressure: Precision wire pitch spacing maintains structural integrity under dynamic airflow without collapsing.
Moisture & Mild Chemical Resistance: Protects against corrosion caused by damp environments, water mist, and non-corrosive air mixtures.
Fast Installation: Easy connection via standard quick-release hose clamps or built-in end cuffs without specialized HVAC tools.
Space-Saving Freight Advantage: Up to 80% compressed volume drastically reduces container shipping costs for overseas buyers.
Recommended Applications
PVC Exhaust Ventilation Duct is optimized for localized exhaust, flexible machine connections, and portable air movement:
Welding & Soldering Fume Extraction: Direct capture of welding smoke at localized extraction arms or portable fan stations.
Industrial Air & Dust Exhaust: Removal of airborne dust, light particles, process odors, and ambient heat from production lines.
Equipment & Enclosure Ventilation: Flexible duct connection for blowers, cooling fans, laser cutters, and CNC machinery.
Temporary & Confined Space Ventilation: Rapid-deploy air supply and exhaust for tunnels, underground utilities, basements, and construction sites.
Laboratory & Chemical Vapors: Exhaust routing for light chemical fumes (chemical compatibility validation recommended prior to exposure).
Product Construction
Engineered with a balanced multi-layer design to maximize durability and smooth air distribution:
Outer Protective PVC Layer: High-abrasion PVC casing that shields against exterior wear, tears, and environmental moisture.
Embedded Steel Wire Helix: Continuous high-carbon spring steel wire locked within the wall layer to maintain circular duct shape under positive and negative airflow pressure.
Smooth Inner Wall: Low-friction interior surface designed to minimize static pressure loss and optimize airflow velocity.
Customization Options
Dimensional Customization: Precision diameters and specified cut lengths tailored to client blowers and ports.
Material Formulations: Anti-static options for dust hazard zones, flame-retardant options for high-risk work environments.
Branding & Packaging: Custom colors, OEM branding, barcode labeling, and retail/distributor packaging.
Accessories & End Connections: Pre-installed clamps, quick-connect sleeves, metal flanges, and reduced-diameter adaptors.
Product Selection Guide
When selecting the correct PVC duct specification, evaluate:
Required Airflow Volume & Static Pressure: Match inner diameter to CFM/m³h requirements to prevent high pressure drops.
Operating Environment: Assess working temperature, relative humidity, chemical concentration, and ambient mechanical stress.
Regulatory Requirements: Identify if flame-retardant or anti-static properties are mandatory for job site compliance.
Physical Installation Constraints: Determine connection type, line length, and frequency of relocation.
Comprehensive Quality Assurance
Every production batch undergoes strict quality control before dispatch:
Raw Material Inspection: PVC tensile strength and chemical safety compliance (RoHS/REACH).
Dimensional Accuracy: Strict tolerance checks on inner diameter, wall thickness, and wire pitch.
Flexibility & Wire Bonding: 10,000+ cycle bend testing and spiral wire adhesion inspection.
Pressure & Air Tightness: Leak testing and positive/negative pressure stability checks.
Standardized Export Packaging
Compression Packing: Vacuum-compressed rolls wrapped in protective PE film.
Outer Protection: Packed into reinforced double-wall corrugated cartons or heavy-duty woven bags.
Palletization: Fumigated wooden or plastic pallets wrapped with stretch film for safe container loading and unloading.

Frequently Asked Questions
Q: What exact technical details are required to get an accurate quotation?
A: Please provide the duct inner diameter, segment length, operating temperature, required flame-retardant rating (if any), total quantity, and shipping destination port.
Q: Is PVC Exhaust Ventilation Duct safe for chemical fume extraction?
A: Standard PVC is resistant to moisture, alkalis, and mild acid vapors. For high-concentration organic solvents or aggressive acids, please contact our technical team with your specific gas composition for compatibility testing.
Q: What are your Minimum Order Quantity (MOQ) policies?
A: For standard diameters (100 mm – 400 mm), our standard MOQ is 50 rolls. For custom colors, special wall thicknesses, or custom branding, MOQ starts at 100–200 rolls depending on specification complexity.
Q: Can you provide samples for quality evaluation prior to bulk orders?
A: Yes. Free 1-meter material samples or standard short-length sample ducts are available for qualified procurement buyers. Freight costs can be collected or credited toward the initial bulk order.
Q: What is the typical lead time for wholesale and OEM orders?
A: Standard orders (100–500 rolls) are typically produced within 12–15 business days. Custom OEM orders or full container loads (20GP/40HQ) generally take 20–25 business days after sample approval.
