Aluminum and PVC vent pipe ventilation hose not only has a huge difference in the material production process, and applications in the industry also has a similar distinction, the price difference is also big differences between the ventilation hose with PVC double-layer aluminum foil ventilation hose; Category ventilation hoses also are many, as described in this article is the foil material with conventional PVC hose ventilation ventilation hose.

First, you can first understand the nature of the significant differences between them under the double aluminum ventilation hose is made of high-grade aluminum foil (layer) outside the adhesive layer of imported glass fiber cloth, spiral wire support and made of aluminum foil is usually applied insulation and flame height, maximum pressure 350MMWG; PVC ventilation hoses As the name suggests, is mainly made of PVC material within the spiral wire support, on top of the lower PVC hot wire bonding, adhesion to strengthen the attachment and tension, PVC ventilation hoses are also flame-retardant effect, but the drawback is not insulation, does not apply to the use of extreme low temperatures, PVC at very low temperatures likely to cause the cracking tube body.

However, for different industries, also has a similar distinction, double aluminum foil ventilation tube through long use in air conditioning installation, indoor and outdoor ventilation, the most common is the central air-conditioning duct, this pipeline need to add insulation material; but also for the in many parts of the kitchen, as fumes pumping tube, and some factory chimney directly as oil, aluminum foil duct temperature is generally -30 degrees to 150 degrees.

PVC ventilation hose made of different materials, are not suitable as air conditioning ducts, general electronics factory soldering smoke used, bathroom exhaust chamber is evacuated, machinery, factory exhaust ventilation, chemical, gas and other exhaust hose; PVC ventilation pressure hose is advantageous not only 300mmwg, at the same time has a high elastic bending resistance, easy construction, the general temperature of -15 degrees to 80 degrees.

Final note, customers in the choice of the ventilation hose, you should first consider what industry, what are resistant to temperature requirements, you can choose what kind of material the ventilation hose, the paper can be used as a reference to the customer to make the purchase process avoid unnecessary economic loss.
