Clean Air Walk-In Fume Cupboards

Clean Air designs and manufactures a series of standard walk-in fume cupboard ranges to keep you safe and protected. We also design custom walk-in units precisely tailored to your specific application.

A walk-in fume cupboard is appropriate for projects that utilise large equipment. It may also include a particular drainage or spillage containment feature.

Both the High Performance Radius Profile range and the cost-effective, angle sided Standard range are available as a walk-in option. Each model has its own strengths.

Our experience and success in bespoke design capability speaks for itself. Our specialist walk-in fume cupboards are installed in prestigious projects such as The National Graphene Institute, the Graphene Engineering Innovation Centre (GEIC), Imperial College London and several of the Henry Royce Institute locations.

Walk-in Fume Cupboard Ranges

Clean Air’s robust, high-quality High Performance Radius Profile and Standard walk-in fume cupboard models are designed to perform.

They are designed to meet the requirements of BS EN 14175 and type tested on a project specific basis for assurance of their excellent containment.

Bespoke walk-in fume cupboards

Our professional 3D design teams can tailor your walk-in fume cupboard to your exact specification. We are always happy to work with you to innovate and adapt designs.

Pass-through ports, bespoke sash arrangements, relocated service outlets, internal drip cups, VAV control and fire suppression systems are just some of the extra features we can add into the units.

Our walk-ins can also be manufactured from Grade 316 Stainless Steel, with Trespa®, stainless steel, PVC or polypropylene linings.

Sash arrangements

The standard arrangement is a double sash opening. However, Clean Air has a wealth of experience in the design of bespoke sashes for specialised applications.

We can include motorised or counterbalanced sashes and sashes with horizontal openings for operator comfort and protection.

Our auto sash closing system can keep operators safe and reduce energy costs.

Bespoke flooring and sumps

Clean Air walk-in fume cupboards can be supplied with a selection of different flooring and drainage options:

  • Open to floor
  • Removeable stainless steel perforated walk-on panels with bunded sump
  • Cast epoxy resin or Trespa® TopLab®BASE bunded working level
  • Low profile ramp for easy equipment access

Working level

The unit can be manufactured to accommodate an intermediate removable working level at heights to suit your requirements. Because this slides out when not required it adds flexibility of use to the unit.

The working level can be fabricated from stainless steel, Trespa® TopLab®BASE or cast epoxy resin.

Energy-saving fume cupboard technology

Clean Air’s walk-in designs can be supplied as Constant Air Volume (CAV), Low Volume or Variable Air Volume (VAV) units.

Our technologically advanced energy efficient system reduces the volume of air pulled through the fume cupboard. As a result the lab requires less conditioned air to replace what has been extracted.

In combination with an auto sash closure system this can significantly reduce energy costs.
