4. Air Permeability: per design – 6, 13, 20 and 29 (+3/-3) cfm/ft² per ASTM D737, Frazier

5. Temperature Range: 0 degrees F to 180 degrees F

B. SYSTEMS FABRICATION REQUIREMENTS:

1. Air dispersion accomplished by linear vent and permeable fabric. Mesh type to include mesh vent to resist stress of frequent laundering.

2. Size of and location of linear vents to be specified and approved by manufacturer.

3. Textile permeability specified and approved by manufacturer.

4. Inlet connection to metal duct via cinch and loop DuctBelt supplied by manufacturer.

5. Lengths to include required 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. Fabric system shall include connectors to accommodate suspension system listed below.

8. Any deviation from a straight run shall be made using a gored elbow or an efficiency tee. Normal 90 degree elbows are 5 gores and the radius of the elbow is 1.5 times the diameter of the DuctSox.

C. DESIGN PARAMETERS:

1. Fabric system shall be designed from 0.25” water gage minimum to 3.0” maximum, with 0.5” as the standard.

2. Fabric porosity (6, 13, 20, or 29 cfm/ft²) determined by manufacturer per airflow.

3. Fabric system shall be limited to design temperatures between 0 degrees F and 180 degrees F (-17.8 degrees C and 82 degrees C).

4. Design CFM, static pressure and diffuser length shall be designed or approved by the manufacturer.

5. Do not use fabric diffusers in concealed locations.

6. Use fabric diffusers only for positive pressure air distribution components of the mechanical ventilation system.

D. SUSPENSION HARDWARE: (one of following)

1. Tension Cable: System shall be installed using a tension cable system including a single (1 Row) or double strands (2 Row) of cable located 3” above top-dead-center (1 Row) or 3” above the 10 and 2 o’clock locations of the DuctSox system. 2 Row supports are required for systems of 32” diameter and larger. Hardware to include cable, eye bolts, cable clamps and turnbuckle(s) as required. System attachment shall be made using nylon snap clips spaced 24 inches. Component options include (must specify per area if multiple on same project):

1. Galvanized Steel Cable

2. Stainless Steel Cable

3. Plastic Coated Stainless Steel Cable

2. 3×1 Suspension: (Available on duct diameters from 16” to 48”) System shall include a 3 Row connection to fabric system at 10, 12, and 2 o’clock locations. Attachment spacing is not to exceed 3 feet. The powder-coated aluminum hangers are secured and integrated to a single (1 Row) tension cable every 3’ and connect to the fabric system at the 10 and 2 o’clock locations with detachable D-Clasps. The fabric system will also have clips located at 12 o’clock to attach directly to the single tension cable system located 3” above top-dead-center location of the fabric system. Tension cable hardware to include cable, eye bolts, cable clamps, and turnbuckles as required. Component options include:

a. Galvanized Steel Cable
b. Stainless Steel Cable
c.

3. Suspended H-Track: System shall include a single (1 Row) or double (2 Row) runs of aluminum H-Track system located 1.5” above top-dead-center (1 Row) or 1.5” above the 10 and 2 o’clock (2 Row) locations of DuctSox system. 2 Row supports are required for systems of 32” diameter and larger. Hardware to include 10’ sections of track, splice connectors, track end caps and vertical cable support kits – consisting of a length of cable with a locking stud end and Gripple quick cable connectors.
