Linear vents must be sized in 1 CFM per linear foot increments (based on .5” SP), starting a 1 CFM through 90 CFM per linear foot.  Linear vent is to consist of an array of open orifices rather than a mesh style vent to reduce maintenance requirements of mesh style vents.  Linear vents should also be designed to minimize dusting on fabric surface.
2.	Size of vent openings and location of linear vents to be specified and approved by manufacturer. 
b.	Fixed Nozzles

3.	Location and number of nozzles to be specified and approved by manufacturer.
c.	Adjustable Nozzles 
1.	Air dispersion accomplished by adjustable ball nozzles and permeable fabric.  Adjustable ball nozzles to have multiaxial rotation to redirect airflow to desired area.  Adjustable ball nozzles are able to completely close off airflow without adding caps or plugs.  Adjustable ball nozzles should lock into place once set, preventing constant adjustment.  Adjustable ball nozzle should have inset design to be a condensation resistant product.
2.	Colors of adjustable nozzles available are white and black.  With white material receiving white adjustable nozzles and all other material colors receiving black adjustable nozzles unless otherwise specifically mentioned on drawings or otherwise in the specification.
3.	Quantity and location of adjustable ball nozzles to be specified and approved by manufacturer.
3.	Inlet connection to metal duct via fabric draw band with anchor patches as supplied by manufacturer.  Anchor patches to be secured to metal duct via. zip screw fastener – supplied by contractor.
4.	Inlet connection includes zipper for easy removal / maintenance.
5.	Lengths to include required intermediate zippers as specified by manufacturer.
6.	System to include Adjustable Flow Devices to balance turbulence, airflow and distribution as needed.  Flow restriction device shall include ability to adjust the airflow resistance from 0.06 – 0.60 in w.g. static pressure.
7.	End cap includes zipper for easy maintenance.
8.	Each section of the textile shall include identification labels documenting order number, section diameter, section length, piece number, code certifications and other pertinent information. 

D.	DESIGN PARAMETERS:
1.	Textile air diffusers shall be designed from 0.25” water gage minimum to 3.1” maximum, with 0.5” as the standard.
2.	Textile air diffusers shall be limited to design temperatures between 0 degrees F and 180 degrees F (-17.8 degrees C and 82 degrees C).
3.	System overall design; diameter, length, airflow, operating static pressure and dispersion shall be designed or approved by the manufacturer.
4.	Do not use textile diffusers in concealed locations.
5.	Use textile air dispersion systems only for positive pressure air distribution components of the mechanical ventilation system.  

PART 3 – INSTALLATION

3.1	INSTALLATION OF TEXTILE AIR DISPERSION SYSTEM:
A.	Install chosen suspension system in accordance with the requirements of the manufacturer.  Instructions for installation shall be provided by the manufacturer with product.

3.2	CLEANING AND PROTECTION:
A.	Clean air handling unit and ductwork prior to the DuctSox system unit-by-unit as it is installed.  Clean external surfaces of foreign substance which may cause corrosive deterioration of facing.
B.	Temporary Closure: At ends of ducts which are not connected to equipment or distribution devices at time of ductwork installation, cover with polyethylene film or other covering which will keep the system clean until installation is completed.
C.	If DuctSox systems become soiled during installation, they should be removed and cleaned following the manufacturers standard terms of laundry.
