  • Custom Sizes & Spec

    Custom built to suit you and your application

The ISG Polypropylene Walk-in fume cupboards are the ideal choice for protecting operators who are using large or heavy equipment that needs containment yet will not fit into a “bench-top” design cupboard.

Available in both ducted and ductless models.

  • Ducted: Harmful fumes and particulates and vented away from the user via ductwork and externally mounted fan(s) controlled by user-friendly touch screen panels.
  • Ductless: Harmful fumes and particulates are drawn away from the user and then filtered before being recirculated into the room.

The large front opening allows access for mobile benches or trolleys and the one-piece metal-free construction* ensures zero corrosion over time – ideal for the majority of applications** especially where corrosive solutions are being used – A variety of linings are available.

Sealed LED lighting offers eco-friendly, cost-effective 800 LUX illumination that will last many times longer than older fluorescent types.

We make these to ANY size (height, width, depth etc) and without any bespoke charge. You simply pay for the material used as the manufacturing costs are identical regardless of size.

We have had them independently tested and certified to not only BS EN 14175 but also to ASHRAE 110-1995 for international Clients.

Safety and Compliance

Our cupboards are built to comply with BS EN14175 and also to ASHRAE 110 – 1995. There are many safety features that can be built into the design of our fume cupboards. These include low air flow alarms (both visual and audio), VAV (Variable air volume) systems to ensure constant face velocity and other systems such as fire suppression and fire collars can be installed to maintain a safe working environment.
