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.

1300D Reinforcement Inside the Composite

The 1300D base specified for DLT-5308 is enclosed by PVC film faces in the stated structure. It should be reviewed together with the finished 600gsm nominal mass and layer bond. Denier describes yarn size rather than a completed connector’s strength. The source tensile and tear entries need verification, so they should not be used to calculate an allowable connector load without corrected supporting information.

Joining the Connector to the Duct

The material-to-material seam and the connector’s fastening edges are separate fabrication details. Test both on a DLT-5308 sample made with the selected face and intended joining method. Define any fire or static requirements with an applicable test method. Because the static-resistance figures in the source conflict, the intended acceptance limit must be confirmed before it becomes part of a technical order.

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.

Duct Construction And Connections

Layflat Blowing Duct
DL

A welded top fin carries the suspension points. The end sleeve seals the connection between sections.

Spiral-Reinforced Extract Duct
DL

The reinforcement supports the duct wall during extraction. Wire specification and pitch follow the suction duty.

Duct Connector Fabric: Layers, Joints and Attachment Edges

DLT-5308 is duct connector fabric with a 1300D polyester base between PVC film faces. Its nominal mass is 600gsm with a ±10gsm tolerance. The base entry identifies the reinforcing yarn size, while the finished mass includes the complete composite. This distinction matters when selecting sheet material for a connection that will also contain seams, clamps or other fastening details.

The PVC faces provide the surfaces handled during fabrication. Their bond to the textile is separate from a joint made to connect two duct sections. The source includes an adhesion value, but a connector seam still needs its own trial using the actual overlap and production method. The specification does not identify the precise coating or laminating route used to produce the sheet.

The stated width range is 1.02m to 3.2m, with black and yellow RAL 1018 listed and custom colours available. Self-extinguishing and antistatic descriptions also appear in the source. These should be supported by agreed methods and requirements for the supplied configuration. The static-resistance expressions need clarification, and the listed tensile and tear entries need verification before they are used for design.

For ventilation duct joints, develop the connector around the actual diameter, movement and fastening arrangement. A representative assembly can show whether reinforcement or changes to the edge construction are required. The material data alone does not establish pressure capacity or service life. Confirm the sheet configuration, joint construction and operating conditions as linked parts of the proposed connector.
