Zipper duct

Introduction

Zipper duct can be divided into positive and negative air duct, duct pressure, high-temperature high-pressure cylinder forming a whole technology, vertical seamless, flame retardant, antistatic, wind resistance, seamless wind and high strength, suitable for coal mine tunnel local fan support for forced ventilation. eamless cylinder vacuum duct elastic spring steel billet heightening the use of advanced high-pressure heat sealing process is refined, it has a suction effect, easy to bend, easy transportation and storage (each section individually wrapped), longer life etc., applicable to coal mine dust ventilation, especially suitable for pumping gas use, but also for other dust tunnel ventilation.
Zippered duct, especially for large diameter duct size, it has a connector is not easy to leakage, easy to transport, carry, and easy to use. Shaped duct, head size hairdryer, trigeminal hairdryer, pants duct, high quality PVC material with high elastic spring steel refined, especially for multi-port and fans began to air, double fan strongly parallel air, with air supply flexible, multi roadway while air, ease of use.
