• a workbench finished in hard-wearing, acid resistant ceramic tiles with rounded corners to facilitate easy cleaning;

Single Sided Fume Cupboards

Main Body

The main body of each Viking Plastics’ fume cupboard is fabricated from welded unplasticised Polyvinyl Chloride (uPVC). uPVC is one of the best materials for use in highly corrosive environments as uPVC:

• retains its smooth gloss surface permanently, even in the presence of gases and chemical;
• is hard to ignite and will not support combustion once the source of ignition is removed;
• provides a neat appearance as well as a high level of chemical resistance.

Base

Each workbench is finished in hard-wearing acid-resistant ceramic tiles with rounded corners to facilitate easy cleaning. The front edge of the workbench area is raised to contain spillages.

Door/s (Sash)

Each unit is fitted with a vertically sliding counter-weighted, 4.5mm thick, clear PVC sash (door) to adjust the size of the opening. To ensure there is always air flow through the fume cupboard, when the sash (door) is fully lowered, a 70mm opening remains.

Air flow / Baffles

Airflow is regulated within the fume cupboard to maintain a minimum face velocity of 0.5 metres per second, regardless of the position of the sash (door) opening.  Baffles are fitted to the rear of the work-chamber to facilitate efficient airflow and direct air to the back of the cupboard and out through the exhaust duct. Baffles are easily removed for cleaning and no tools are required for their removal or re-installation. Vents located on the upper front panel ensure the face velocity air flow remains constant.

Double Sided Fume Cupboards

Double sided fume cupboard have all the standard features of single sided fume cupboards plus the following:

• two vertically sliding counter-weighted, 4.5mm thick, clear PVC sashes (doors). Doors are located on opposite sides of the cupboard;
• each side of the fume cupboard has a full set of controls;
• to prevent cross-draughts, a door alarm is fitted to ensure only one door is open at any one time.

Fittings and Controls

Lighting

Fitted with an internal fluorescent light to illuminate the work surface to a minimum of 400 lux.

Control System

Each fume cupboard is fitted with a comprehensive control system.  The control system runs the gas, power, light, extraction fan (with pre & post purge time periods), display status and visual and audible alarm functions. The control panel automatically ensures the fan is running with a 5 minute pre-purge and 20 minute post-purge time periods to ensure all toxic fumes are extracted from the cupboard. An emergency stop button (manual reset type) immediately disconnects the electrical power and gas to the fume cupboard while allowing the exhaust fan to continue operating to ensure the fume cupboard is completely purged of fumes.
