Duct fans increase the effectiveness of heating, cooling, and ventilation systems in industrial, commercial, and residential settings. They push warm or cool air through a room or space, remove toxic substances, and maintain temperature in critical environments. Duct fans can be placed at the mouth or intervals of a duct and carry the risk of […]
Duct filters remove contaminants from air flowing through central heating and cooling systems. They capture dust, pollen, and pet dander, making them beneficial for allergy sufferers. Filters need to be periodically changed or cleaned. Installation is usually simple and can use custom or standard filters. A duct filter is a type of air filtering device […]
Air conditioning ducts distribute air throughout a building and are a central component of HVAC systems. They carry cool air in summer and heated air in winter, along with ventilation needs. Ducts come in different sizes, shapes, and materials. The supply duct carries fresh air from the unit to each room, while the return duct […]
Duct panels are made of fiberglass and foil, used for heating and air conditioning insulation. They are lightweight, durable, and easy to install. The fiberglass insulates the air passing through and prevents the spread of mold, while the foil acts as a vapor barrier. Duct panels also reduce noise from HVAC systems. A duct panel […]
The common bile duct carries bile from the liver and gallbladder to the small intestine. It is joined by the pancreatic duct and regulated by the sphincter of Oddi. Blockages can cause jaundice and require surgery or ERCP to remove stones. The common bile duct (CBD) is an important part of the gastrointestinal tract responsible […]

Thyroglossal duct cysts are fluid-filled masses near the thyroid gland that are present at birth and usually discovered when infected. Treatment involves removing the cyst or monitoring its size with ultrasound or thyroid scans. The Sistrunk surgical procedure may be necessary for larger cysts. A thyroglossal duct cyst is a fluid-filled mass found near the […]
Furnace ducts are used to distribute heat in buildings and homes. They are made of metal or plastic and can be placed under the floor, above the ceiling, or suspended from the ceiling. Furnaces are often connected to ducts, and it’s important to maintain seals in each segment. The ducts are joined together and have […]
Duct tape doesn’t work on ducts, according to a scientific study. Of the 33 types of sealants tested, duct tape was the only one that failed reliably. Despite this, duct tape remains popular for other uses. It was developed by Johnson & Johnson during World War II and is sometimes called “duck tape”. The amount […]
Duct design for HVAC systems involves four main types: trunk and branch, radial, spider, and perimeter loop. All designs revolve around the furnace unit, with size varying based on building size. The trunk and branch method is common, while radial and spider methods are efficient for smaller buildings. The perimeter loop is less common. Duct […]
Make a duct tape bag by cutting and gluing strips of tape together to form a sheet, cutting the sheet into a desired shape, folding it over, and attaching a strap. Use different colors of tape for a unique look. A duct tape bag is a do-it-yourself fashion accessory. As the name implies, it is […]
Bile duct obstruction occurs when bile tubes become blocked, causing medical conditions such as jaundice and fever. Causes include cysts, gallstones, inflamed lymph nodes, and tumors. Symptoms include pain, dark urine, and jaundice. Diagnosis methods include physical exams, blood tests, and imaging. Treatment depends on the cause. A bile duct obstruction, also known as biliary […]
Masking tape is reinforced tape used for shipping and sealing containers. It includes filaments for strength, and can be clear or brown.
