FUME CUPBOARDS FOR WORKING WITH
WEAK ACIDS OR ACIDIC SUBSTANCES
COMMONLY REFERRED TO AS: ZAFE 81, ZAFE 82, AND ERGO ZAFE 83
DEFINITION
This fume cupboard is exclusively intended for working
with weak acids, with no heat involved.
FUME CUPBOARD CONSTRUCTION
- The interior of the fume cupboard is lined with laminate.
- The extraction duct is made of galvanized steel or
polypropylene.
- Metal components are either made from acid-resistant
stainless steel or coated with polyester powder paint.
- Worktop materials can include: polypropylene, epoxy,
acid-resistant stainless steel, or a ceramic material.
- The front glass is made of tempered safety glass.
- There is no temperature monitoring in the fume cupboard.
- The fume cupboard is available with a height-adjustable worktop/cabinet.
CONSIDERATIONS
Choosing this fume cupboard is close to selecting a
standard fume cupboard, with only a few exceptions,
making it more cost-effective than an acid fume cupboard. Since the work involves only handling weak acids
or acidic substances, there are more options for selecting the worktop material.
As stainless steel is typically visually affected by substances that come into contact with its surface — and as
cleaning and maintenance are needed to maintain its
original appearance — we recommend using a polypropylene, epoxy, or ceramic worktop instead.
CERTIFICATION OF THE FUME CUPBOARD
If certification of the fume cupboard is required, it will
fall under EN 14175 Part 3, which covers the testing and
certification of standard fume cupboards. This model
will not require compliance with EN 14175 Part 7, as the
testing in EN 14175 Part 3 is sufficient.
Additionally, in Denmark, it is required that the fume
cupboard undergoes tracer gas testing according to DS
457 in the laboratory before it is put into operation.
MAINTENANCE AND INSPECTION
It is recommended that the fume cupboard be inspected
and serviced at 12-month intervals, depending on usage.
For safety reasons, it is crucial that mechanical components, load-bearing parts, and the ventilation system
are checked frequently, at a minimum following the
suggested interval.
Zystm offers a service package specifically designed for
this type of fume cupboard.
