What is the best ducting?
Sheet metal air ducts are the most durable type of air duct construction, and because of their non-porous surface, are the least likely to have mold or biological growth.
How many types of ducting are there?
There are three main types of rigid ductwork: sheet metal ducts, fiberglass lined ducts, and fiberboard ducts.
What is the function of duct How are duct classified?
Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air.
Why is ducting equipment important?
Properly sized and installed ductwork has multiple benefits. First, it will reduce the strain on your HVAC equipment, prolonging its life and saving you money in energy costs. Second, your air will be cleaner with fewer dust particles, allergens, and germs floating in the air.
What is galvanized duct?
Most ductwork manufactured with galvanized metal is hot-dip galvanized, a process of coating steel with a thin zinc layer. Galvanized sheet steel ducting is commonly used in most dust collection ducting applications.
Why is duct size important?
If your ducts are too small to accommodate the air flowing through them, the pressure increases and backs up in the system. This causes resistance for the blower fan, reducing your HVAC system’s efficiency and longevity.
What type of metal is used for ductwork?
Made of galvanized steel or aluminum, rigid sheet metal is the most common type of ductwork. The thick, solid wall makes the duct very durable. The interior is known to trap dust and other particles, but the smooth surface is generally easy to clean.
What is a PVC duct?
Used mostly by contractors and builders, PVC duct is a thin walled version of traditional PVC pipe. Because of its thin walls, duct is not used to carry pressurized liquids like standard pipe. Instead, it is used for light drainage, fume, and exhaust applications.
