FUME CUPBOARDS DESIGNED FOR WORKING
WITH STRONG ACIDS AND HIGH HEAT
COMMONLY REFERRED TO AS: ZAFE 81 AC HH OR ERGO ZAFE 83 AC HH
DEFINITION
This fume cupboard is intended for working with strong
acids and high temperatures.
king with strong acids and high heat. Given the extreme
conditions, we strongly recommend a ceramic worktop,
as high temperatures and high acid concentrations can
severely damage other materials.
FUME CUPBOARD CONSTRUCTION
- The interior is lined with polypropylene.
- Equipped with a ceramic heat shield above the worktop to protect the cabin from heat radiation.
- The extraction duct is made of polypropylene.
- Metal components are coated with technical Teflon polytetrafluoroethylene (PTFE), resulting in a black appearance.
- Worktop material: Ceramic only, to withstand high
temperatures and strong acid exposure.
- The front glass is made of tempered safety glass.
- The front glass is top-hinged with wire suspension.
- Includes temperature monitoring.
- Requires extra-high ventilation volume, with the
airflow speed recommended to be at least three times
that of a standard fume cupboard.
- It is recommended to install the fume cupboard at a
fixed height, avoiding height adjustment to prevent
the need for highly chemical-resistant flexible piping.
- Fittings can be Teflon-coated, depending on requirements,
and should always be rinsed after boiling processes.

MAINTENANCE AND INSPECTION
It is recommended that the fume cupboard be inspected
and serviced at 3-6 month intervals, depending on its use.
For safety reasons, it is critical that mechanical components,
load-bearing parts, and the ventilation system are frequently checked, at a minimum, according to the suggested interval. Zystm offers a service package specifically designed for
this type of fume cupboard.
