Product Description


x-series is a quickly assembled series for round ventilation ducts. the series except the ducts is based on
a double-lipped,factory-installed seal made from EPDM rubber. the moulding,which can withstand rough handing,
and is almost insensitive to temperature changes, has a great gas tighteness.

advantage of x-series
1. quick assembly
2. factory fitted seal with no loose fittings
3. can be twisted and adjusted, but has no effect on the gas tighteness
4. installation without sealant or solvents
5. can be used in all kinds of climates
6. the gas tighteness can keep good from 5000 Pa negtive pressure to 3000 Pa positive pressure
7. both ends of the fittings are disposed with the process of turnup, which makes both ends smooth, reinforced
and also underformed.

1. that is impossible that the x-series can keep the perfect and complete gas tighteness. in general, the
connection between ducts and fittings will exist the situation of air leak normally, but we can guarantee
that the leakage is much lower than the international standard. and leakage will increase with the
increase of the differnce between inside pressure and outside pressure.
2. X-series includes ducts , bends, reducers,connection branch,couplings, joints,dampers,silences,and so on.
the detailed thicknesses and specifications can be produced as required.
3. all the products in X-series are made of galvanized or stainless steel
