Tips Before You Buy: Why Does a Hose Need a Wearstrip?

Just as some ducting hoses resist internal abrasion, a wear-strip protects a hose from external abrasion. Hoses often see use in heavy-duty applications where they come into frequent contact with abrasive surfaces. Over time, abrasion degrades the hose walls, wearing out the hose. A wearstrip wraps around the hose’s exterior in a spiral, receiving any abrasion and allowing the hose walls to last longer.

Wearstrips are especially useful for ducting used in enclosed spaces, such as mining shafts. Air ventilators and material collection ducts extend the full length of the mine, and tend to be dragged along the ground or against the shaft’s walls when transported. Flex Ducts with wear-strips resist external abrasion also last longer, and are thus more useful for these kinds of heavy-duty applications.

A flex hose’s external wear-strip often follows the same path as the internal metal wire helix. Because of the wire’s weight, when a hose is dragged on the ground, the hose wall tends to receive the most abrasion near the wire helix. By following the same path as the wire helix, the wear-strip protects the part of the hose that wears out fastest.

Ducting Insights: Thermoplastic Rubber Ducts in the Outdoors!

Since outdoor temperatures vary throughout the day and from season to season, outdoor ducting hoses need to be able to withstand a variety of conditions to function long-term. As a result, ducting hoses made from thermoplastic are ideal for outside installation.

As their name suggests, thermoplastics are designed to handle both hot and cold temperatures. This allows these sturdy hoses to function at different times of the year, enduring the heat of summer and the chill of winter. For instance, the Thermoplastic Flex Medium Duty has an operating temperature range of -40º to +275º Fahrenheit. Thermoplastics are flexible, sturdy polymers, typically a combination of rubber and plastic. These waterproof materials allow thermoplastics to resist moisture from rain or other weather conditions.

Thermoplastic hoses have excellent resistance to other outdoor factors that can damage other ducting materials over time, such as UV light, ozone, and various chemicals. They also resist internal abrasion from common outdoor materials and debris. Light-duty thermoplastic hoses see use in dust collection or air ventilation, while heavy-duty thermoplastic hoses are often used to transport sand and gravel.

Leaf Vac Hoses

Perfect for suburban homes or mountain compounds both, mechanical leaf vacuum hoses are an excellent way to keep your property leaf-free. Everyone loves nature, and it is an understatement to say that trees add value to property. However, it is just reality that trees, bushes, and shrubbery of all varieties produce messy deposits of leaves, sticks, and other wooden refuse. That is why a good lawn vac hose can mean the difference between a clean and an enjoyable property versus a bedraggled one coated with rotting leaves.

The modern day leaf hose machine generally takes the form of a motorized, lawn tractor. These tractors can be operated much like a sitting lawn mower, that is to say, where the driver is perched on top of the machine and navigates it similarly to an automobile. Though they, of course, can come in all shapes and sizes, many lawn vac hose machines are powered by engines of up to 223 ccs and can hold roughly 200 gallons of leaf waste and other landscaping refuse. Some of the higher end models also feature steel impellers in the collection duct area of the tractor, which mulches up incoming debris and thereby increasing the total potential volume of the container massively while in use.

Probably the most critical component of any leaf vacuum worth its salt, however, is the lawn vac hose. Though they can come in several differing materials, polyurethane and rubber are two highly favored choices of consumers in the common, residential leaf hose market. Both of these materials are durable and long-lasting, and can withstand the multitude of damaging abrasives that leaf vacuum hoses face in their day-to-day operation. By installing a purposefully reinforced hose into the design of their mechanical leaf tractors, manufacturers are taking an important step in providing you –the consumer- with a lawn vac hose system you can rely upon for all your home landscaping and leaf removal needs.

When it comes to the leaf vacuum hoses and ducting themselves, it is critical that they be the proper size, in addition to being made from the necessary material. 8 inch duct is a commonly selected sizing of leaf hose because it is naturally capable of handling large amounts of refuse. There are few things worse than attempting to unclog a leaf-stuffed duct while in the midst of a busy landscaping project on a hot day. That is why it is so important to use an 8 inch duct (or larger) to ensure all your lawn vac jobs remain safe and efficient. As an aside, an 8 inch duct is compact enough to still produce maximum sucking power and ventilation. 8 inch leaf vacuum hoses really do make the best of both worlds.

If you are a homeowner, landlord, or resident who is tired of raking up pesky leaves by hand, seriously consider getting yourself a fully-operational leaf vacuum hose tractor. These tractors are purpose-built and designed to make tedious yard work as quick and enjoyable as possible. Know that when you use leaf vacuum hoses to handle all your leaf collection and disposal needs you are ensuring that your yard receives only the best and most thorough of care!

Best Sellers – Air Ventilator Hoses

Air ventilation hoses are designed with several different factors in mind. As such, these ducting hoses are very versatile products and have a huge number of potential uses. To boil it down to basics, the hose products are made to transfer air and facilitate circulation. But within that very broad definition, there is a huge number of applications that the hoses can be used for.

The Air Ventilator hose range is so versatile and effective because of the way the products are made. They are constructed from PVC rubber and vary in size from a 4-inch diameter to 24-inches, making them useful in every setting, from small-scale to industrial. The ducting is reinforced with a spring steel wiring that makes it extremely strong, even when flexed. It is also resistant to heat, standing up to a range of temperatures from -20 to 180 degrees Fahrenheit, while the Air Ventilator hoses can also compress to a fraction of their usual size.  These hoses have a 10 to 1 compression ratio, meaning a 25 footer can compress to a 2.5ft size.

The range of applications for the Air Ventilator hoses are far-reaching. If there’s a need for air ventilation then this duct hose can fill it. That includes air conditioning, mobile and fixed chillers and dehumidification units. With the temperature resistance capabilities and the variety of sizes available, the hoses can be used in any setting, from an in-home HVAC system to large industrial machinery which needs ventilation tubing. While air flow – specifically in cold and heating systems – might be the primary use for the air ventilator hoses, they also have plenty of more obscure capabilities, such as a smoke ejector.

Portable AC Hose

When a project requires an AC hose to be frequently moved between locations, it presents a unique set of demands that requires a portable hose. Portable AC hose products need to be durable, flexible, and compressible. They also need to be able to withstand the rigors of the outdoors. For work that requires high levels of movement, it is also important to have a retractable hose for convenient transportation. The benefits of having a proper portable AC hose are no more evident than when it is used in—of course—a portable air conditioning unit.

What Causes Black Dust on AC Vents?

Black dust on AC vents is caused by leaking ducts pulling in unfiltered air from dusty, dirty areas of your home. Because HVAC units cycle air, this unclean air adds extra sediment to your system. Even if your kitchen, bathrooms, and bedrooms are gleaming, your attic or in between your walls are probably not. Of course, you cannot do much to prevent dust from building up in these untouched areas of your house—hence, it falls upon your HVAC ductwork to compensate. If gaps or cracks in the AC-unit ductwork circulate inside your household, these leaks can pull dusty air from your ceiling or crawl spaces into the ducting. If air filters are the bouncers that prevent particles from entering or exiting the central air-conditioner duct-system, then dirty air sucked in from outside sources can be considered the uninvited gate-crashers, infringing on the process of HVAC. Dryer vent work—when it crosses by a leaky HVAC hose—can also be a source of dark-colored dust coming out of AC vents inside your home. Despite whether a dryer hose or a dusty attic is what causes black dust, the main issue is leaky AC ductwork. Not only do leaking ducts suck in unfiltered air, but they also reduce airflow inside your HVAC system, leading to uneven heating and cooling and an inefficient unit. Therefore, it is imperative to watch out for signs of leaky HVAC air-ducts—elevated energy bills, uneven HVAC, excessive dust levels, and more.

Agricultural Hoses

The potential uses for heavy duty hoses when it comes to agricultural and resource cultivation concerns are practically limitless. Agricultural hoses are important to so many facets of these industries because of its ability to move plentiful and/or heavy material from one location to another, while conserving labor and energy. The flex tube itself is a revolutionary development within the agricultural ducting market. Having a length (or series of lengths) of agriculture hoses that can bend and move in varying ways has a laundry list of advantages over more immovable and inflexible ducts. From floor duct to gypsum transporters to fertilizer broadcasters, it is clear to see that potential agricultural hose implementations are only limited by the imagination of the consumer.

Farms and other resource cultivation areas exist for the sole purpose of generating and gathering the various products and material required for our modern day societal needs. According to www.agday.org, “Forty-one percent of the U.S. total land area is farmland (938.28 million acres). In 1900, the average farm size was 147 acres, compared to 441 acres today.” For reference, one acre is almost the size of a standard 100-yard American football field. With such massive amounts of agricultural land present in the United States (let alone the world as a whole), heavy duty hoses and ducts are perhaps now more important than they have ever been.

A primary use of agriculture hoses are for the purposes of functioning as a collection duct. Grains, feed, and wheat (all commonplace products on almost any given farm or ranch) all require short-and long-term storage. This is where the collection duct comes into play. Often made from rubber, polyurethane, or stainless steel, these kinds of agricultural hoses rely on either gravity or suction to absorb fallen grain and feed, and transport it to a suitable storage basin.
