Description
This premium PVC ventilation pipe reducer is designed to provide a smooth, reliable transition between different duct sizes in industrial and commercial ventilation systems. Manufactured from robust PVC with excellent chemical resistance, it helps maintain consistent airflow while connecting mismatched pipe diameters in extraction, supply air and general HVAC layouts.
Ideal for use in factories, workshops, warehouses, laboratories and plant rooms, this reducer is suitable for both new installations and upgrades to existing systems. Available in a wide range of size combinations, it allows installers to adapt to site conditions quickly and efficiently while ensuring a secure, airtight connection.
Product Features
- Manufactured from durable PVC for long-lasting performance in industrial and commercial environments.
- Available in multiple size combinations, including 110 x 75mm, 110 x 90mm, 125 x 110mm, 160 x 110mm and 200 x 110mm, plus additional options to suit varied duct layouts.
- Precision-moulded internal surfaces promote smooth airflow and help minimise pressure loss across the reduction.
- Excellent resistance to many common industrial chemicals and cleaning agents.
- Lightweight construction for easier handling and quicker installation compared with metal fittings.
- Compatible with standard round PVC and similar rigid duct systems used in HVAC and process ventilation.
- Suitable for both horizontal and vertical duct runs in extract and supply air applications.
Key Features and Benefits
- Ensures efficient system performance by providing a controlled transition between different pipe diameters, helping to reduce turbulence.
- High chemical resistance makes it well suited to ventilation of areas where fumes, vapours or cleaning chemicals may be present.
- Simple push-fit or solvent-weld installation (depending on system design) can reduce installation time and labour costs.
- Corrosion-resistant PVC construction offers a low-maintenance alternative to metal reducers in harsh environments.
- Wide choice of size options allows flexible system design and straightforward integration into existing ductwork.
- Robust moulded body provides a secure, stable connection for long-term reliability in demanding applications.

Frequently Asked Questions
How do I choose the correct size of PVC ventilation pipe reducer?
Select a reducer with inlet and outlet dimensions that match the external or nominal diameters of your existing ductwork or equipment spigots. For example, if you need to connect 160mm duct to 110mm duct, choose a 160 x 110mm reducer. Check your system drawings or measure the ductwork to confirm the required sizes.
Can this PVC reducer be used with both extract and supply air systems?
Yes, the reducer is suitable for use in both extract and supply air systems, provided it is installed within the recommended temperature and chemical exposure limits for PVC. It can be used in general HVAC, dust and fume extraction, and other low to medium pressure ventilation applications.
Does the reducer need to be solvent welded, or can it be push-fitted?
The installation method depends on your duct system design and site requirements. In many cases, the reducer can be used as a push-fit component with suitable seals or duct tape, but for a more permanent and airtight connection in demanding environments, solvent welding with a compatible PVC adhesive is often recommended. Always follow your system specifications and local installation guidelines.
