Our Foul Air – Air Conditioning Triangles provide a clear, high-visibility solution for marking airflow direction in ventilation and ductwork systems. Whether you are installing new HVAC ducting, carrying out maintenance, or upgrading existing systems, these triangles make it easy for contractors, engineers, and inspectors to follow airflow paths accurately. Furthermore, the bold design ensures visibility even in complex or low-light installations.

Standout Features for Professional HVAC Projects

• Clear Airflow Identification – Improves accuracy in system labelling.

• Permanent Adhesive – Bonds securely to most clean, smooth surfaces.

• Durable Gloss Vinyl – Resists moisture, dust, and frequent handling.

• Supplied in Sheets of 5 – Convenient for storage, transport, and bulk use.

• DW/144 & Appendix C Compliant – Meets recognised sheet metal ductwork standards.

Built for Compliance and Long-Term Visibility

From large-scale ventilation projects to smaller ducting systems, these triangles perform reliably in demanding environments. The permanent adhesive ensures they stay exactly where placed, while the robust gloss vinyl keeps colours bright and lettering sharp over time. Consequently, airflow direction markings remain visible and compliant throughout the life of the installation.
