Negative pressure fabric air ventilation system

  LEED Points

Fabric air ducts and air dispersion systems are truly a value proposition. A better performing air dispersion system, at a lower cost, and many benefits that can be used to help achieve more LEED points. Depending on your project, Fabric air ducts may help you attain points in the areas of indoor air quality, acoustic environment and thermal comfort.

Everything is included in a Fabric air dispersion system 

Many functions known from conventional metal ducts are fully integrated in a fabric air dispersion system, making diffusers, grilles, dampers, etc.is redundant. Fabric dispersion systems are all inclusive. You can forget about the following when using fabric air dispersion
systems:
1).No extra grilles or diffusers are necessary. The fabric air dispersion systems function as both a duct system and as an air dispersion system.
2).No extra noise reduction is needed (except perhaps reduction of fan noise). Noiseless is the standard.
3).No inconvenient alterations or assembly on site. A fabric air dispersion system fits straight from the factory, is assembled with zip fasteners and is ready for installation as soon as it arrives.
4).No damper is necessary. A fabric air dispersion system does not require balancing.
5).Painting is not necessary as the fabrics are dyed.
6).No extra insulation is necessary. Fabric air dispersion systems are condensation free. 

30-70% less expensive than metal

Fabric air dispersion systems offer multiple opportunities to save money without sacrificing quality or flexibility in design. Utilizing Fabric Air dispersion systems can result in 30-70% savings over the cost of conventional ducting through a simple installation process, economical shipping solutions, space-savings and efficient materials.

A versatile system design

Fabric Air dispersion systems do not have limitations when it comes to elbows, reducers and take-offs, such as conventional metal ducting does. If you can imagine it, Then we can produce it. If you are used to metal ducting then you know to take your wallet out when you hear "non-standard". At fabric air duct, non-standard is what we do, because every job is custom. Any angle, any length, any diameter... Give us a call and we will turn what you have imagined into reality in three weeks or less

The entire duct is an air diffuser

In a fabric air dispersion system the fabric ducts distribute air along the entire length of the duct at the desired angle. The full length even air distribution is a standard feature of fabric air dispersion systems and does not come with a significant price premium, which is the case when using conventional metal ducts. The full length distribution comes in two varieties: Linear Flow Models (LFM) and Surface Flow Models (SFM). These two methods can be co-specified as needed. For example, a swimming pool would require a permeable fabric to avoid condensation; an SFM. It would also require a type of LFM,, to wash the perimeter surfaces.

Full length air dispersion is enabled through permeable fabrics and directional perforations in the surface of the ducts. This creates uniform, draft-free and condensation-free air distribution throughout the entire space, regardless of system complexity.

Metal ducts need grills and diffusers, which results in highly complicated installations and higher energy consumption. These additional fittings often cause uneven air distribution and add to the expense, space requirements, man hours, etc. of the project. Such uneven air distribution is a major cause for uncomfortable and unhygienic work environments as they lead to draft and condensation problems.

we design our air distribution and air dispersion systems with efficiency and excellence in mind. The fabric ducts are breathable, which makes every part of the duct functional and efficient, creating a uniform air distribution. Higher control and precision provides the area with a superior comfortable climate as far as ventilation, heating and cooling is concerned.

Full-length air dispersion allows for the gentle, noiseless exit of air from the duct surface. Ideal comfort with lower energy consumption is achieved through combining flow models to suit the specific area requirements. The use of tailored flow models allows the system to suit virtually any design requirement the end-user has without compromising the air dispersion results.

Easy installation

Fabric air dispersion systems are intuitive and simple to install. Each duct section is marked with an individual tag, which lets you know exactly where each piece should go. There are no trade specific tools required; everything you need can be found in a handy-man's tool box. Easy installation significantly reduces labor hours compared to metal ducts or other fabric duct systems. This helps to ensure that your project is built on time and within budget

Sustainable ventilation with a low carbon footprint

Fabric air dispersion and distribution systems have a smaller carbon footprint than conventional metal ducting. Fabric air ducts require less energy to produce and transport, and with a significantly lower weight fabric ducts place considerably less load stress on the construction, making the system ideal for retrofitting as well as new builds.

The efficiency of air distribution in fabric ducts is much higher and more precise than with conventional metal ducting. This means they can run at a low static pressure drop and require less energy to operate.

Efficient solution regardless of ceiling height

Depending on the application, Fabric air ducts and dispersion systems can be tailored to suit the specific needs of your building, by using the best flow model or combination of multiple flow models.

For example, in buildings with low ceiling heights, low-throw air flow models are often the option of choice to eliminate drafts. However, if the building has high ceilings and requires heating, high-throw flow models are used to ensure that the air reaches the occupied zone and to help avoid stratification. Fabric air dispersion systems ensure the ideal air distribution regardless of room size and ceiling height.

Lightweight design for heavy duty ducts

Fabric air ducts offers the most heavy duty ducts in the industry, in a lightweight design. Our ducts weigh as little as 300 g/m² [8.8 oz/yd²], thus it is like comparing a feather to a hammer, when compared to conventional metal systems. This is important especially in connection with retrofitting existing building mass, as Fabric air dispersion systems will not significantly affect the structural integrity. As a quick rule of thumb, using 3 kg/m [2 lbs/ft] for calculation purposes will provide a fair conservative estimate for the structural engineer in 99% of all project. The weight of an actual duct with suspension depends on the length and diameter of the duct. However, most popular fabric, Porous material Type A, weighs approximately 1/20 of steel sheet ducting

A flow model to fit your specific needs

we produced many different flow models to meet the specific demands of any project. The appropriate flow model depends on a number of project specific factors. What type of conditioning is being supplied: heating, cooling, ventilation, or a combination of the three? Are there any specific air velocity requirements? Do the requirements differ from room to room? There are more questions that may be asked, and the answers determine what flow model will be the best fit for your application. Rest assured, no matter what the requirements are for your application, we has the flow model to fit your needs.
