We've made some changes to EPA. Knowledge about air duct cleaning is in its early stages, so a blanket recommendation cannot be offered as to whether you should have your air ducts in your home cleaned.Rice university today
The U. Environmental Protection Agency EPA urges you to read this document in it entirety as it provides important information on the subject. Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle e. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes.
Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to your health.
There is substantial visible mold growth inside hard surface e. There are several important points to understand concerning mold detection in heating and cooling systems:. If any of the conditions identified above exists, it usually suggests one or more underlying causes. Prior to any cleaning, retrofitting, or replacing of your ducts, the cause or causes must be corrected or else the problem will likely recur. Some research suggests that cleaning heating and cooling system components e.
However, little evidence exists that cleaning only the ducts will improve the efficiency of the system. You may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should be occasionally cleaned.
Provided that the cleaning is done properly, no evidence suggests that such cleaning would be detrimental. EPA does not recommend that the air ducts be cleaned routinely, but only as needed. EPA does, however, recommend that if you have a fuel burning furnace, stove or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. If you do decide to have your air ducts cleaned, take the same consumer precautions you normally would in assessing the service provider's competence and reliability.
Air duct cleaning service providers may tell you that they need to apply chemical biocide to the inside of your ducts as a means to kill bacteria germs and fungi mold and prevent future biological growth. They may also propose the application of a "sealant" to prevent dust and dirt particles from being released into the air or to seal air leaks.
You should fully understand the pros and cons of permitting application of chemical biocides or sealants. While the targeted use of chemical biocides and sealants may be appropriate under specific circumstances, research has not demonstrated their effectiveness in duct cleaning or their potential adverse health effects.
No chemical biocides are currently registered by EPA for use in internally-insulated air duct systems see Should chemical biocides be applied to the inside of air ducts? Whether or not you decide to have the air ducts in your home cleaned, preventing water and dirt from entering the system is the most effective way to prevent contamination see How to Prevent Duct Contamination.
Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. Many companies are marketing products and services intended to improve the quality of your indoor air.At its core definition, a ducting hose is tube-like piece of equipment, with an opening at each end, which is made to transfer something from point A to point B.
These ducts are made specifically to move a range of materials. This range includes five categories — air of varying temperatures, dust and other fine particles, abrasives, larger non-abrasive materials, and fumes. There is no one ducting hose product which will be perfectly suited to each different type of material movement. A wide variety of hoses are available, all with different designs and made with different materials, and all boasting different capabilities.
Hose materials include PVC, coated polyester fabric, neoprene, silicone, thermoplastic rubber, aluminum, stainless steel and more. Each will provide different qualities. For instance, PVC ducting can provide a high degree of flexibility, while stainless steel is ultra strong and rigid. Some materials provide a higher working temperature, while others handle exposure to chemicals.
To ascertain what kind of duct is needed in any particular setting, you need to know what will be travelling through it, what temperature it must be able to handle, whether it needs any resistance to chemical exposure, whether it will be used with positive or negative pressure, and what size is needed in terms of length and diameter. In most cases, the open ends of the ducting hose are attached in place using a connector, clamp or belt.
The applications for a hose can include everything from transferring air within an air conditioning system, sucking up sand, pebbles and other small debris and abrasives, to ventilating harmful fumes.
In each of these applications — and many more — the hose itself does not have any powers of positive or negative pressure. It is simply there as a conduit, providing the channel to transfer a material from A to B.
Flexible ducting comes in a wide variety of materials and sizes, guaranteeing an ideal hose for each and every application. While it is nice to have so many options, selecting a flexible ducting made from the wrong material result in damage or total destruction of the hose. When compared to other ducting materials, the rubber hose is the most versatile option available, and luckily it comes in a variety of different elastomers and sizes to ensure a match for any application.
Unlike other ducting materials, a rubber hose can be used to transport a variety of different substances. From liquids to air, dust, and even small materials such as rocks and leaves, nearly anything can be transported through flexible rubber ducting. You will see them commonly used everywhere from a home ducting system to vacuum cleaners, motor vehicles, and industrial machinery. Rubber flex hoses made from thermoplastic are particularly a popular choice for most applications due to their enhanced physical durability.
A thermoplastic rubber hose can even be used for external applications, as the material resists ozone and UV rays better than alternatives.
Thermoplastic rubber ducting can even withstand chemical exposure and high temperatures without compromising its strength or flexibility. Though other ducting materials demonstrate stronger chemical and temperature resistances, no other material offers the same wide range of physical resistances that are found in the rubber hose. For versatility and exceptional strength across the board, flexible rubber ducting is as good as it can get. Ducting comes in a wide variety of materials and sizes, guaranteeing an ideal hose for each and every application.
While it is nice to have so many options, the choices can be overwhelming to a duct heating novice. It is important to choose the right heating duct for your system, otherwise you may end up with poor air quality, circulation, or worse — a damaged heater hose.
Next time you are shopping for a heating air duct, make sure the product you choose hits these important points:. Heat-Resistant Hose — This may seem like a no-brainer, but it is important to choose a heating duct that can handle the temperatures present in your application. There are several different kinds of heat-resistant Hose that perform under different maximum temperatures.
Portable Ventilation Ducting
For commercial and industrial applications that experience higher temperatures, fiberglass heating hoses can be coated with silicone or aluminum. Durability — Flexible heat ducting is usually fairly sensitive, no matter what material it is made of.
The risk of tears and punctures in the material is high for both transporting the heat duct and installing it. Many heating ducts come equipped with wear strips to prevent such damage and ensure safe handling of the tubing.
Insulation — Regardless of whether you are installing a cooling or heating duct, insulation is an important quality to have. An insulated heating duct has an extra layer to it that protects the airflow and temperature from escaping while maintaining an efficient level of flexibility. This is important for any heat ducting system in order to ensure that air quality and temperature levels are up to par.
Now available in numerous materials and gauges, quick fit ductwork has expanded from its dust collection beginning to the preferred option in hundreds of different industries.

Welded seams prevent leaks and damages. Available in galvanized or stainless steel. Covid Plan.The duct, or air distribution, system used in cooling and heating your home is a collection of tubes that distributes the heated or cooled air to the different rooms.
This branching network of round or rectangular tubes—usually constructed of sheet metal, fiberglass board, or a flexible plastic-and-wire composite—is found within your home. Leaks, one way in which conditioned air is lost in the duct system, make the HVAC system work harder, thus increasing your utility bill. In addition, duct leakage can lessen comfort and endanger your health and safety.
Your duct system has two main air-transfer systems—supply and return. The supply side delivers the conditioned air to the home through individual room registers—what you feel blowing out of the registers.
The return side withdraws inside air and delivers it to the air handler of your central system. All of the air drawn into the return duct s is conditioned and should be delivered back through the supply registers.

The needed airflows include, for example, supply airreturn airand exhaust air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. A duct system is also called ductwork. Planning laying outsizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design.
Galvanized mild steel is the standard and most common material used in fabricating ductwork because the zinc coating of this metal prevents rusting and avoids cost of painting. For insulation purposes, metal ducts are typically lined with faced fiberglass blankets duct liner or wrapped externally with fiberglass blankets duct wrap. When necessary, a double walled duct is used. This will usually have an inner perforated liner, then a 1—2" layer of fiberglass insulation contained inside an outer solid pipe.
Rectangular ductwork commonly is fabricated to suit by specialized metal shops. For ease of handling, it most often comes in 4' sections or joints. Round duct is made using a continuous spiral forming machine which can make round duct in nearly any diameter when using the right forming die and to any length to suit, but the most common stock sizes range evenly from 4" to 24" with 6"" being most commonly used. Stock pipe is usually sold in 10' joints. There are also 5' joints of the non-spiral type pipe available, which is commonly used in residential applications.
Aluminium ductwork is lightweight and quick to install.
Also, custom or special shapes of ducts can be easily fabricated in the shop or on site. The ductwork construction starts with the tracing of the duct outline onto the aluminium preinsulated panel. Aluminium tape is applied to all seams where the external surface of the aluminium foil has been cut. A variety of flanges are available to suit various installation requirements.
All internal joints are sealed with sealant. Aluminum is also used to make round spiral duct, but it is much less common than galvanized steel. Traditionally, air ductwork is made of sheet metal which was installed first and then lagged with insulation. Today, a sheet metal fabrication shop would commonly fabricate the galvanized steel duct and insulate with duct wrap prior to installation.
However, ductwork manufactured from rigid insulation panels does not need any further insulation and can be installed in a single step.
Both polyurethane and phenolic foam panels are manufactured with factory applied aluminium facings on both sides.How to refresh the page in sapui5
The thickness of the aluminium foil can vary from 25 micrometres for indoor use to micrometres for external use or for higher mechanical characteristics. Most manufacturers of rigid polyurethane or phenolic foam panels use pentane as foaming agent instead of the aforementioned gasses. A rigid phenolic insulation ductwork system is listed as a class 1 [ clarification needed ] air duct to UL Standard for Safety.
Fiberglass duct board panels provide built-in thermal insulation and the interior surface absorbs [sound], helping to provide quiet operation of the HVAC system.Product Price : Get Latest Price.
