Frequently Asked Questions
Q: What is the diameter of this flexible aluminum exhaust duct?
A: The duct has a diameter of approximately 100 mm (4 inches), making it compatible with standard 4-inch exhaust fans, range hoods, inline fans, and HVAC fittings.
Q: Can this aluminum ventilation hose be used in a grow tent or greenhouse?
A: Yes! This flexible aluminum duct is an excellent choice for grow tents, greenhouses, and grow rooms where consistent airflow and temperature management are essential. Its wide operating temperature range (-30°C to 100°C) and high-pressure tolerance make it suitable for both intake and exhaust applications.
Q: How flexible is this duct — can it bend around corners?
A: Absolutely. The spiral steel wire construction allows the duct to flex, extend, and compress, making it easy to route around corners, through walls, and into tight spaces without losing its shape or restricting airflow.
Q: Is the duct heat-resistant and safe for use near kitchen appliances?
A: Yes. The double-layer aluminum foil construction offers strong heat resistance, with a rated temperature range of up to 100°C, making it well-suited for kitchen exhaust and range hood venting applications.
