APPLICATIONS:
Product Features
- AntistaticHelps manage electrostatic charge build-up in the fabric, giving manufacturers a material option for assemblies with specified static-control requirements.
- Flame retardantA flame-retardant formulation for fabricators supplying projects with defined fire-behaviour requirements. Select the grade around the test method required for the finished application.
680gsm Composite, Specified Layer Structure
DLT-5306 is described as PVC film on both sides of a 1000D polyester base. Its nominal 680gsm includes that complete construction. Check the supplied sample’s surfaces and layer bond before trial fabrication, keeping the distinction between material adhesion and seam strength. The data does not identify the exact production route, and the source tensile and tear entries need verification before being used for design calculations.
Specifying Temporary Ventilation Material
A temporary duct specification should connect DLT-5306 to a defined diameter, joining method and support layout. Include the required fire and static test criteria if they apply. The source uses inconsistent static-resistance expressions, so confirm the intended limit rather than carrying those numbers into an order. The finished system’s pressure performance depends on the assembled duct and cannot be inferred from its sheet mass.
Application requirements — Ventilation Ducts
Specify duct diameter and section length, positive or negative operating pressure, airflow conditions, connector design and suspension spacing. Review tensile and tear properties, coating adhesion, seam integrity and leakage in the assembled duct. Identify any required fire behaviour, static-control and temperature criteria for the installation; these must be checked against the selected configuration and applicable test evidence. Another application is dog play and agility tunnels. For these, specify the tunnel diameter, length, support hoops, anchoring and cleaning needs; assess the seams and the finished tunnel around the intended dogs and setting.
Common Finished Ventilation Duct Specifications
| Specification | Typical Configuration |
|---|---|
| Duct Construction | Layflat blowing duct; spiral-reinforced duct for extraction or bends |
| Layflat Diameter Examples | 300–3000 mm nominal diameter |
| Layflat Section Lengths | 5, 10, 20, 30 or 50 m sections |
| Reinforced Duct Examples | 250–1400 mm diameter; 5 or 10 m sections |
| Section Connections | Zip, hook-and-loop, reinforced eyelet or end-ring connections |
| Suspension | Welded suspension fins or reinforced patches on layflat ducts; rings on reinforced ducts |
| Seams And Attachment Areas | Welded body seams, sealed connection sleeves and reinforced suspension areas |
| Operating Duty | Define blowing or extraction, fan airflow, static pressure and installed length together |
Duct Construction And Connections
A welded top fin carries the suspension points. The end sleeve seals the connection between sections.
The reinforcement supports the duct wall during extraction. Wire specification and pitch follow the suction duty.

Ventilation Duct Fabric: A Reinforced Sheet for Assembly
DLT-5306 is listed as a 680gsm ventilation duct fabric with a ±10gsm tolerance. The stated structure places a 1000D polyester base between PVC film faces. This identifies a reinforced composite rather than an unsupported PVC sheet. Its mass includes the textile and covering layers together, so weight should be considered alongside the construction and required assembly tests.
The layer bond and the duct’s fabricated joints need separate attention. An adhesion entry is provided for the sheet, but that value does not describe a seam made later by a duct manufacturer. The exact coating or lamination route is not established in the model information. Confirm the selected material and joining method together on a representative piece before producing long duct sections.
The listed colours are black and yellow RAL 1018, with custom colours available, and the stated width range is 1.02m to 3.2m. Self-extinguishing and antistatic characteristics are included in the source. Their acceptance should be tied to defined test methods and the actual supplied version. The static-resistance figures require clarification before they can be used as a numerical procurement requirement.
For temporary ventilation ducts, the diameter, length, suspension and air conditions shape the finished assembly. Review seams, joints and any supporting reinforcement under the intended conditions. The tensile and tear entries in the source require verification, so they should not be used to derive a working pressure or load. A completed duct system needs its own performance assessment beyond the choice of roll material.
