Hazardous dust, fumes, and vapours in a workplace can create havoc. A Local Exhaust Ventilation (LEV) system is one of the most effective solutions to combat this. However, this raises a key question/decision that your business will have to make: should you invest in a bespoke LEV system design, or choose an off-the-shelf solution?
Both options come with their own set of advantages and challenges. The right choice depends on your operations, risks, and long-term goals. This guide explores the differences between a custom-made LEV system design and standard equipment, the role of LEV testing, and how to decide what’s best for you.
Why does an LEV system matter?
LEV systems are designed to capture airborne contaminants at source before they spread through the workplace. Why would you choose a LEV system design?
- Professional LEV systems are efficient, resulting in lower costs and better performance.
- Customised LEV designs factor in your workplace structure, resulting in a more efficient set-up.
- Regular testing helps keep your workplace safe, legally compliant, and up to date with UK health and safety standards.
What is an off-the-shelf LEV system?
Off-the-shelf LEV systems are pre-designed and manufactured ventilation systems available for purchase, offering a more readily available solution for businesses.
Before making a purchase, what should businesses know about off-the-shelf LEV systems?
Advantages of an off-the-shelf LEV system
- Lower cost – Since the solutions are standard, they can be slightly cheaper than a bespoke system.
- Quicker installation – As the equipment is ready-made and requires less design work, the installation process is usually quicker.
Limitations of an off-the-shelf LEV system
- Less flexible – An off-the-shelf system is less flexible as they are more standard-made.
- Potential inefficiency – The airflow for an off-the-shelf LEV system may not be fully optimised as it can not be customised to your needs.
- The system may not provide adequate control if not specified correctly.
- Possible higher maintenance costs- A poor fit can lead to frequent failures and repeated LEV testing issues.
Therefore, for businesses with more standard and straightforward needs and smaller budgets, an off-the-shelf option might be more practical. However, you should always seek guidance from a reputable LEV provider before making any decisions. When it comes to more complex environments, bespoke is usually the way to go.
What is a bespoke LEV system design?
A bespoke LEV system design is a custom-made system that is better suited to the facility’s specific needs, layout, risks, and processes. This approach starts with an expert assessment of the workplace and results in a local exhaust ventilation (LEV) design that integrates seamlessly into your operations.
What factors should you account for while going for a bespoke LEV system design?
Advantages of a bespoke LEV System design
- Tailored performance – Since the bespoke design is custom-made, it ensures maximum efficiency.
- Compliance confidence – LEV systems are designed to prevent the exposure and inhalation of airborne contaminants and harmful substances, reducing risks in the workplace. Vent Tech’s bespoke LEV systems are fully HSE compliant.
- Scalable and efficient – As bespoke LEV design systems are customised, they are also scalable and designed for long-term use, ensuring efficiency and reduced costs.
Limitations of a bespoke LEV system design
- Higher initial costs – Customised solutions and tailored installation make the process slightly more expensive compared to an off-the-shelf solution. Although purchasing the incorrect off-the-shelf solution and having to replace it can end up costing considerably more in the long run.
- Design and installation time – As the systems are customised and tailored to your facility, the process might take longer than buying a readily available off-the-shelf solution.
LEV Testing and Equipment
Whether a business chooses a customised LEV system design or an off-the-shelf solution, commissioning followed by regular LEV testing is a legal requirement and an essential part of maintaining an effective LEV system.
Why is LEV Testing Important?
- It keeps your LEV system efficient
- Ensures your warranty and insurance are validated
- Helps businesses stay safe, vigilant, and compliant with safety standards.
Both bespoke LEV systems and off-the-shelf options can be effective, depending on a business’s needs. While a bespoke system is ideal for complex environments, an off-the-shelf solution may be suitable for certain applications.
Whichever route you take, remember that success does not stop at installation. Proper commissioning and regular LEV testing is essential to keep your workplace safe, compliant, and efficient.
