If you've ever worked in a kitchen in a hotel, restaurant, or inn, you know these places generate a significant amount of smoke. This smoke must be promptly vented outdoors to prevent indoor air quality from becoming extremely poor. To achieve this, a circular duct is required. This circular duct is known as a spiral duct, which comes in various types and serves 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, commonly found in the market, share the characteristics of stainless steel spiral ducts but at a lower price. Composite spiral ducts have lower environmental requirements and are also quite practical.

Applications of Spiral Ducts

1. Spiral ducts are used for air supply and exhaust of cooking fumes. Spiral ducts are employed for air distribution and ventilation. In some production workshops or factories, indoor production can generate waste gases or harmful substances. When these gases are discharged outdoors, spiral ducts are utilized. They expel indoor gases to the outside and bring outdoor air into the building. This is the air supply function of spiral ducts. Spiral ducts are also used for exhaust of cooking fumes, commonly found in kitchens. Here, they are also referred to as smoke and fume ducts.

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

Helical ducts can remove dust. In areas with poor air quality and high dust levels, dust removal systems are necessary. In large air flow conduits, helical ducts are the go-to solution. Helical ducts can serve as an insulating medium for material transport. They have a pleasing appearance and offer thermal insulation, making them ideal for transporting loose particles such as expanded plastics. Their performance is quite effective.

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