BioGuard™ Flexible Polyolefin Ducting
BioGuard Flexible Ducting inhibits mold growth while being extraordinarily easy to install and economical.
Its unique polyolefin material is light weight. Because it is round and light permeable, it has no dark corners, the most common breeding ground for mold in rigid metal ducting.
Does your facility need BioGuard ducting?
Yes! Almost every building suffers from negative pressure which is created by exhaust fans. This negative pressure has very expensive consequences and also makes for a less comfortable work environment:
- Heated air is vented by Roof Fans
- Temperature stratification causes Hot and Cold Spots
- Windows are Drafty
- Dust and fume issues are exacerbated
- and much more...
Did you know that facilities with negative pressure are also losing almost 90% clean and/or treated air through roof fan exhaust systems?
Conventional HVAC systems are inefficient at controlling air distribution. The BioGuard ventilation system, with its flexible ducting, distributes air evenly throughout the building giving you much greater control of air distribution. So, by using the basic principles of air pressure and the physical laws of nature, air distribution and control are easily solved by BioGuard.
So, why BioGuard?
- It saves you money
- Itís inexpensive and easy to install
- It will save you huge amounts of money ó payback of two years or less are common
Your people will be breathing easier and working better. Employees have been known to give management a round of applause once the BioGuard ventilation system is installed.
Hereís how BioGuard works in a typical winter application in a facility with fume, stratification, negative pressure, draft and stagnation problems:
- Fumes are exhausted at the floor level
- Cool make-up air is brought in at ceiling height and dispersed evenly over a long path through holes punched in the tube at 10 oíclock and 2 oíclock. (Engineering results determine number of holes, size and exact location.) More air is brought in than is exhausted, creating a slight positive pressure.
- Wasted stratified heat is used to preheat the cool make-up air. A side benefit is the dramatically reduced amount of energy required to heat your plant. BioGuard evens the temperature from floor to ceiling and reduces heat loss through the roof.
- Air flow is now from the ceiling to the floor, trapping fumes at floor level and forcing them down and toward the production exhausts, keeping heated air where itís needed. The building is now at a positive pressure, eliminating drafts and reducing worker discomfort, complaints and illness.
