Super-sized walk-in fume cupboards for the pharma industry

Two extra-large stainless-steel walk-in fume cupboards have been dispatched from Clean Air’s Bolton factory bound for the States. The advanced specification units have been specially designed for Howorth Air Technology.

The Brief

Two super-sized stainless-steel walk-in fume cupboards were required as an integral part of a pharmaceutical project for the States. Howorth USA called in UK fume cupboard specialist Clean Air to design and manufacture the units to an exacting specification for a HPAPI (Highly Potent Active Pharmaceutical Ingredients) installation.

Stainless-Steel Walk-in Fume Cupboards

Clean Air’s priority is keeping operators safe. As with every Clean Air model, these walk-in fume cupboards are designed to meet the stringent containment requirements of BS EN 14175.

The giant units measure an impressive 2.4 m wide by 1.5 m deep by 3.6 m high to accommodate the apparatus used in the pharmaceutical application.

To ensure the end user’s high standard of clean room conditions is maintained, they are fabricated internally and externally from 316 grade polished stainless-steel.

Walk-in Fume Cupboard Access

As a safeguard for the operating personnel, Clean Air recommended a combination of horizontal and vertical sliding sashes. This feature offers simple and safe access with the added benefit of energy cost savings.

Each fume cupboard has three vertically rising sashes. The middle sash also has horizontally sliding windows. This system keeps any gases and fumes contained and offers ease of access to the operator. It also minimises the volume of conditioned air the unit pulls through from the lab.

The top two sashes are fitted on a linked pulley system which allows both to rise quickly and smoothly. The middle sash is designed to rise twice as fast as the top one, so both arrive at their final position simultaneously. This arrangement makes manoeuvring equipment into or out of the units simple and safe.

Custom Flooring Solution

Clean Air has also designed and manufactured a specialist flooring arrangement for the stainless-steel walk-in fume cupboards. The base of the units is a stainless-steel sump that will be sunk flush with the floor and fitted with mesh lift out floor panels. The sump will accommodate any spillage, keeping it safe and contained.
