If you've ever worked in a hotel, restaurant, or inn kitchen, you know these spaces generate a significant amount of smoke and grease. This smoke and grease must be promptly exhausted outdoors to avoid a severely polluted indoor environment. To do this, a circular duct is needed, which is known as a spiral exhaust pipe. There are various types of spiral exhaust pipes, and they serve multiple functions.

A wide variety of spiral ducts are available.

Spiral ducts are categorized based on material and adaptability, including galvanized spiral ducts, composite spiral ducts, and stainless steel spiral ducts. Among these types, stainless steel spiral ducts stand out for their superior quality and versatility. Galvanized spiral ducts are widely available in the market, sharing the characteristics of stainless steel spiral ducts at a lower price. Composite spiral ducts have less stringent environmental requirements and are also quite convenient to use.

The Applications of Spiral Ducts

Helical ducts are suitable for air distribution and exhaust of cooking oil smoke. Helical ducts are used for air supply and ventilation, and in some production workshops or factories, indoor production activities can generate exhaust gases or harmful substances. When these gases are discharged outdoors, they are often channeled through helical ducts. These ducts expel indoor gases to the outside while bringing outdoor air into the building. This is the air distribution function of helical ducts. Helical ducts can also be used for exhaust of cooking oil smoke, commonly found in kitchens. Here, they are also referred to as smoke and oil ducts.

2. Spiral ducts are suitable for dust removal and material transportation.

Spiral ducts are effective in dust removal. In areas with poor air quality and high dust levels, dust removal systems are necessary. In ducts with high airflow, spiral ducts are the ideal choice. Spiral ducts can also serve as an insulating medium for transporting materials. They have an aesthetically pleasing appearance and offer insulation properties, making them suitable for transporting loose particles such as foam plastics. Their performance is quite satisfactory.

After gaining a general understanding of spiral ducts, people can choose the spiral duct that suits their needs. When purchasing spiral ducts, it's advisable to consult with the seller to see if the purchase includes free installation services. If the manufacturer can provide installation services, it will save you a lot of trouble.
