Area of use

heating air in ventilation systems with
circular ducts.
The casing of galvanized steel, copper
tubes and aluminium fins. An inspection
hatch, easily opened with a quick release,
can be completely removed for cleaning
and maintenance.
The VBF has two nipples (ø 5 mm) which
make it possible to measure the pressure
drop over the filter.
Cleaning
The bag filters must be changed once a
year, or more often if necessary.
Dust, dirt and deposits on the fins reduce
the battery’s efficiency. Dry particles can be
blown away with compressed air or steam,
