Introduction
Zipper
duct 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.
