Plastic ductwork in an industry setting?
People are often surprised to hear that plastic ductwork can be used for ventilation in industries that are generating volatile fumes. The truth is that chemically resistant plastic ducting can be just as effective as traditional metal ducting, if not even more so.
Johndec can install plastic ductwork in PVC, PP, PPs, HDPE, and PVDF, ensuring that a suitable material can be used for your ducting, no matter the composition of the fumes that are generated in your line of work.
All of our ducting is manufactured specifically to be used for ventilation and conforms with the fume cupboard design standard AS2243.8 which specifies the safety requirements for laboratory fume cupboards and the test methods that should be used to determine their performance. Additionally, Johndec uses seamless moulded fittings that are segment free, capable of containing gaseous, abrasive, and corrosive media.
We’ve successfully installed plastic ventilation ductwork within the industrial, scientific, commercial laboratory, mining, and commerce markets, including environments where corrosive and volatile fumes are routinely produced.

Why use plastic ducting?
Plastic ducting has several advantages over traditional metal ductwork including cost, adaptability, performance, safety, and durability.
- Plastic ducting is lightweight and simple to install. This means costs are greatly reduced in the installation. With metal ducting, strong ceiling and wall supports are required to support the weight of the ducting. Additionally, plastic ducting is easy to cut on-site.
- The ducting itself is generally cheaper. The cost of plastic ducting is almost always much lower than traditional metal ducting.
- Plastic ducting isn’t as vulnerable to corrosion. Metal ducting is vulnerable to corrosion over time, meaning you may need to replace it sooner. Plastic ducting that is resistant to the fumes it is venting will be less vulnerable to corrosion.
- Plastic ducting offers greater flexibility and adaptability. For example, it’s normally simple to switch between round and rectangular plastic ducting.
- Expanding the ventilation system is easier. Creating branches of the ventilation system to cover other areas can be done with minimal disruption.
- Plastic ducting that has been properly installed can be air-tight, offering maximum efficiency for the material used.
- PVC ventilation ducting of good quality is self-extinguishing. This minimises concerns of fire risk.
Quality you can trust—Beck & HoKa
Johndec Engineering Plastics WA is a distributor of Beck and HoKa products. Both of these companies are German-based companies that specialise in the manufacture of moulded polymer chemical-resistant ventilation ductwork and fittings.
Beck has been involved in the development and production of thermoplastic polymer moulded pipe components for ventilation systems for over 50 years. Hock has been producing plastic ventilation mouldings for more than 30 years with the motto, ‘highest quality in the fastest way’.
Our plastic ducting specifications
The plastic ventilation ductwork suitable for your needs will depend on your industry and activities. We offer prefabricated ducting with diameters ranging from 75 to 1000 mm. In terms of the type of plastic, PVC ducting is suitable for the majority of our customers’ needs. If you need to vent fumes that are incompatible with PVC, an alternative type of plastic material can be used.

Conclusion
Plastic is a versatile material that is exceptionally suited to ventilation ductwork and fittings. Using plastic ductwork can save you money through the cost of materials and installation. Plastic ventilation ductwork is much quicker to install than traditional metal ductwork, and you’ll experience much less disruption to your operations by choosing plastic ventilation ductwork. Plastic is not as vulnerable to corrosion as metal ducting, and plastic ducting can be more durable and last longer.
Johdec offers a huge range of plastic ventilation ductwork and fittings that will satisfy the needs of most customers without them needing to invest in custom plastic fabrication.
