Ducting Basics: 3 Applications That Need Collection Ducts

Material Collection ducts are used every day to help keep our surroundings clean and free of clutter. Here at Ducting.com, we provide the proper ductwork needed to collect various types of debris such as dust, dirt, leaves, and even common paper litter. The types of ducting that are intended for collection purposes are often made of sturdy material such as PVC, thermoplastic, or polyurethane. They tend of have thicker wall hoses in order to accommodate the abrasive nature of the materials that go through them. Here are three examples of major industry applications that require the use of a collection duct:

Agriculture Storage: Workers in rural settings such as farms and ranches need to transfer large amounts of grain and animal feed on a daily basis. They need to use flexible ducts in order to do transport and stockpile these materials. The ducts used in these applications need to be durable. The ducting required in these applications sometimes must be made with FDA acceptable materials due to the fact that they are involved in transporting consumables.

Leaf Blowers: We have all seen and heard leaf blowers in action. They are used in residential and commercial areas to help maintain cleanliness by sucking up leaves and other types of outdoor yard waste. Not only must the duct hoses in these applications be durable, but they need to be made to channel air efficiently.

Woodworking: Few other applications really highlight the importance of collection ducts quite like woodworking. Huge amounts of wood dust and shavings are constantly present in carpenter workshops and furniture warehouses. Such materials can be a health hazard so it is imperative to remove them for everybody’s benefit. Ducting with smooth interiors are very popular for wood dust collection because that prevents any of the fine particulate matter from clogging the ducting.

Tips To Remember Before You Buy

What is diameter?
Diameter is a very important unit of measurement when it comes to flexible duct sizing because all duct sizes are measured according to their diameters. Flexible ducting is normally sized according to the internal (or inside) diameter, often labeled as ID. How do you measure the diameter of a round object? The diameter of a circle is the length of a straight line going from one side of a circle to the opposite side. To measure the diameter, simply choose two points on the edge of a circle that are directly across from each other, and measure the distance between these points.

Do not mistake circumference for diameter
A circle is a two dimensional shape made by drawing a curve that is the same distance all around from the center. Circles have many components including: chords, curves, diameter, radius, tangents, arcs, sectors, semi circles and central angle to name a few. It was Archimedes who developed the formula for determining the area of a circle.

The diameter of a circle is the length of the line through the center and touching two points on its edge. In the figure above, drag the orange dots around and see that the diameter never changes. The diameter is also a chord. A chord is a line that joins any two points on a circle. A diameter is a chord that runs through the center point of the circle. It is the longest possible chord of any circle.

Diameter: The center of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle.

Radius: The radius is half the diameter. Radius The radius is the distance from the center to any point on the edge.

Circumference The circumference is the distance around the edge of the circle.
Diameter = 2R
R is the radius of the circle where:
C is the circumference of the circle
π is Pi, approximately 3.142
