Description
This professional plastic ventilation flange is designed to provide a secure, sealed connection point for ducting and ventilation pipework in demanding industrial and commercial environments. Manufactured from robust, chemically resistant plastic, it offers a reliable interface between ventilation systems and walls, ceilings, equipment housings or enclosures.
Engineered for durability and long service life, the flange is ideal for use in workplaces where resistance to moisture, chemicals and mechanical wear is essential. A wide choice of diameters, from 63 mm and 75 mm through to 90 mm, 110 mm, 125 mm and additional larger sizes, makes it suitable for both small local extract points and larger centralised ventilation or process air installations.
Product Features
- Available in a range of diameters including 63 mm, 75 mm, 90 mm, 110 mm, 125 mm and several additional sizes to suit common ductwork standards.
- Manufactured from high-quality, chemically resistant plastic for reliable performance in harsh industrial atmospheres.
- Flanged design provides a stable, flat mounting surface for securing to walls, panels, ducts or machinery housings.
- Smooth internal bore helps to minimise airflow restriction and pressure losses within the ventilation system.
- Compatible with rigid plastic ventilation pipes and associated fittings used in industrial and commercial ducting layouts.
- Lightweight construction for easy handling and installation, even at higher mounting points or overhead locations.
- Corrosion-resistant material suitable for use in humid, damp or chemically aggressive environments.
Key Features and Benefits
- High chemical resistance – ideal for extraction systems handling fumes, vapours or process air that may be corrosive to metal components.
- Durable construction – tough plastic offers long service life with good resistance to impact, abrasion and general wear in busy plant areas.
- Secure, leak-reducing connection – flanged interface allows for effective sealing to surrounding surfaces, helping to reduce air leakage and maintain system efficiency.
- Versatile sizing range – multiple diameters support both new installations and retrofitting into existing ventilation networks.
- Low maintenance – corrosion-free material reduces the need for repainting, rust treatment or frequent replacement.
- Easy installation – simple geometry allows fast fitting by maintenance teams, helping to minimise downtime during upgrades or repairs.

Frequently Asked Questions
Which diameter of ventilation flange should I choose for my ducting?
Select the flange diameter to match the outside or nominal size of your ventilation pipe or duct. Common options include 63 mm, 75 mm, 90 mm, 110 mm and 125 mm, with additional sizes available for larger systems. Always confirm the duct dimensions and any relevant standards used on your site before ordering.
Is this plastic ventilation flange suitable for use in chemically aggressive environments?
Yes. The flange is made from a chemically resistant plastic designed to withstand many common industrial fumes and vapours. For particularly aggressive chemicals or high-temperature applications, check your process requirements and, if necessary, seek confirmation against the specific substances involved.
Can the flange be used with both new and existing ventilation systems?
Yes, the wide range of diameters makes the flange suitable for new installations and for retrofitting to existing ductwork. As long as the selected flange size matches your ducting and mounting arrangement, it can be integrated into current systems during maintenance, modification or extension work.
