Draft-Free Ventilation and Climate Control Solutions
Q-duct provide a sure solution to all ventilation problems.
Regardless of whether it is high-tech industry, the office, food industry, or simply if
rapid air renewal is required, Q-duct always present a reliable solution to circulation
problems. Even in cold rooms, with temperatures down to -30o F, food & meat
preparation or storage, sterile rooms, sports halls or in the chemical industry, Q-duct
provides the best solution to non-condensing, cold air distribution.
General facts about Q-duct:
- Q-duct is a polymeric fabric impregnated with pinholes to discharge the
air in multiple, tiny air streams that do not induce room air. (This is NOT plastic duct
with dime-sized holes meant to INDUCE room air and mix it up.)
- Q-duct is available in 8 different densities of tiny holes to permit the
desired fabric air velocity and consequent length of fabric duct required.
- Optional "Air-Slots" constructed of polyester fabric can be sewn into the Q-duct
to create a slot diffuser of location and size required for the project. These
"Air-Slots" are integral to the Q-duct, located and sized to
direct a burst of air directly onto specific objects such as windows (to prevent
condensate) or in a continuous linear airstream downward toward the floor (to direct heat)
or horizontally pitched to discharge along a roof (to dry-off moisture).
Unlimited combinations available make Q-duct uniquely desirable for
design engineers to provide the exact air distribution pattern required on each part of
the project. A guideline for selection is attached.
Q-duct SELECTION
- Decide the CFM quantity required for a given building area.
- Determine specific directions and locations where this air should and should not be
distributed (i.e. 4 & 8 o'clock for heating air, 2 & 10 o'clock for roof
blanketing, 4 o'clock for 4' over windows, or "no-slots" for 10fpm, no draught
air.)
- Determine the percent of CFM that should discharge through each of identified slots
(i.e. 75% on a heating application, 100% for roof blanketing, 60% over windows or 0% from
air slots for 100% draft-free air.)
- Decide on the length of Q-duct required to satisfy air distribution requirements.
- Select Q-duct connection diameter with 1500 fpm velocity and 1/2" SP.
(Locate supply duct connection in the middle with multiple side/side fabric ducts to
minimize cost.)
Given this selection information, the engineers at Q-duct will locate
"Air-Slots" of the proper width and length and the fabric with an appropriate
opening density to accomplish the exact air distribution pattern and air quantity
required.
Q-duct OWNER & USER BENEFITS
Q-duct provides a vastly improved method to distribute conditioned
air exactly where required while providing many other benefits:
- Installed ducting and diffuser costs should decrease by 1/3rd.
- Zippers installed at 16' or specified intervals permit periodic, quick washing of the
duct.
- UL NFPA 90A Fire and Smoke Safety listing on Q-duct.
- USDA authorizes use where the inspector in charge of the process approves.
- No rust or condensate can form on Q-duct.
- Four standard color selections (blue, red, yellow & white) and infinite custom
decoration and advertising signs available.
