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 s
pring steel billet heightening the use of advanced high-pressure heat sealing process is refined, it has a suction effect, easy to bend, easy tra
nsportation and storage (each section individually wrapped), longer life etc., applicable t
o coal mine dust ventilation, especially suitable for pumping gas use, but also for other d
ust tunnel ventilation.
Zippered duct, especially for large diameter duct size, it has a connector is not easy to lea
kage, easy to transport, carry, and easy to use. Shaped duct, head size hairdryer, trigemin
al hairdryer, pants duct, high quality PVC material with high elastic spring steel refined, especi
ally for multi-port and fans began to air, double fan strongly parallel air, with air supply flexible, multi roadw
ay while air, ease of use.
