Ventilation hoses are critical for air circulation, fume extraction, and temperature control in industrial, commercial, and even specialized environments. Their design varies widely to meet specific needs like high-temperature resistance, flame retardancy, or flexibility in tight spaces. Below, we explore common types of ventilation hoses, highlighting their structures, key features, and ideal applications—with insights into how Orientflex’s solutions stand out.
1. Flame Retardant High-Temperature Vulcanized Hose
Core Design: Constructed from fiberglass cloth, non-combustible polymers, and silicone rubber, reinforced with a spiral steel wire. Formed by high-temperature rubber curing (300°C), ensuring a smooth, even structure with no rough edges.
Key Features:
- Flame retardancy and non-toxic materials, making it safe for high-heat environments.
- Strong elasticity, anti-UV properties, and corrosion resistance.
- Smooth inner wall reduces wind resistance for efficient airflow.
Applications: Perfect for high-temperature air and fume transport, including dryers, printing machinery, hot air blowers, automobile engine heating systems, and industrial furnaces. It excels at circulating hot/cold air and exhausting industrial fumes in aviation or military equipment.

2. Nylon Mesh Duct
Core Design: A lightweight hose covered with durable nylon mesh, supported by high-carbon steel wire for structural stability.
Key Features:
- High flexibility and easy installation, with a standard length of 10m.
- Heat resistance, acid/alkali tolerance, and strong flame retardancy (self-extinguishing when away from fire).
- Max pressure resistance of 1000Pa, ideal for moderate airflow demands.
Applications: Used in mechanical ventilation systems, chemical waste gas emission, and general industrial air circulation. Its flame-retardant and corrosion-resistant properties make it suitable for harsh environments like chemical plants or high-temperature workshops.
3. PVC Multi-Purpose Telescopic Hose
Core Design: Made from super flame-retardant PVC sandwich cloth, reinforced with thickened high-carbon steel wire and a black encrypted plastic frame. Equipped with metal rings for secure installation.
Key Features:
- Telescopic and flexible, allowing free expansion, contraction, and bending—easy to carry and install in tight spaces.
- Excellent sealing (no air leakage), wear resistance, and high compressive strength.
- Flame retardancy, heat resistance, and insulation, dedicated to air conveying.
Applications: A versatile workhorse for large-scale air management. Ideal for tunnels, basements, machine rooms, municipal projects, mining, greenhouses, and fire rescue. Works seamlessly with portable suction fans for circulating cold/warm air.
4. Temperature Resistant Telescopic Duct (-70~450°C)
Core Design: Built with imported high-quality fiberglass-coated cloth and high-strength fiber thread, clamped by stainless steel clips to form a spiral structure.
Key Features:
- Ultra-light yet tough, with a near-outer-diameter bending radius for easy maneuvering.
- High pressure resistance (up to 5000Pa) and a 1:10 compression ratio for space-saving storage.
- Extreme temperature tolerance from -70°C to 450°C, with a tightly sealed tube wall to prevent leakage.
Applications: Designed for high-temperature fume and gas extraction, including automobile exhaust, high-temperature solder smoke, and boiler hot gas circulation in industrial machinery.

5. High-Temperature Telescopic Duct (-70~800°C)
Core Design: Features multi-layer heat-resistant fiber, high-temperature coating, and high-strength fiber thread, with metal clips forming a spiral extension structure.
Key Features:
- Industry-leading temperature range (-70°C to 800°C), making it suitable for extreme heat environments.
- Same robust pressure resistance (5000Pa) and flexibility as its lower-temperature counterpart, with a 1.2:10 compression ratio.
- Tight airtightness ensures no leakage, even under intense thermal stress.
Applications: Critical for special machinery, high-temperature boilers, and heavy-industry hot gas circulation/discharge—where extreme heat resistance is non-negotiable.
