Install the Nilfisk exhaust filter when the cleaner's exhaust air must be "white-room" clean. This is especially important in chemical, pharmaceutical, ceramic, asbestos, lead, electronic, pesticide pro cessing areas and other high-hazero industries. Ideal as well for laboratories, "white rooms," computer centers and hospitals.
Special versions of the Nilfisk GA72 and GA73 have been approved by the Bonn Institute for Dust Research, for use in areas where high-hazard dust such as asbestos, is being processed. Both ma chines are equipped with exhaust-filters, a main filter which can be shaken externally, and a manometer to indicate to the operator when the main filter needs to be shaken.

All Nilfisk filters are oversize. This allows the air to pass through them more slowly, insuring better filtration. It also means that only a very small percentage of ultra-fine dust particles reaches the exhaust filter, extending its life.

Dust particle size is measured in micrometers ||im, which equals 1/1000mm). Human hair is 60-80pm thick (60-60/1000mm). Niifisk exhaust filters retain 100% of dust particles 1pm (1/1000mm) and 69.99% of particles down to 0.3pm in size. The following table shows the particle size of various dusts:
the exhaust filter is installed or removed by turning clockwise or counterclockwise. The cartridge is replaceable.

NILFISK exhaust filter
Improves air quality in high-hazard workplaces
Pharmaceuticals By using the Nilfisk exhaust filter, the operator is protected against dangerous dust exposure while cleaning equipment.
Lead In spite of strict employee protection measures in force where lead compounds are processed, hazardous dust is generated when com ponents are moved. Vacuuming with a Nilfisk machine equipped with exhaust filters is the best way to prevent this dust from being
raised and inhaled.
Ceramics The dangerous microscopic dust found in ceramic works causes silicosis. It is so fine, that only by using Nilfisk exhaust filters,
can it be dealt with hygienically.
Health Care Facilities To maintain the highest possible standards of hygiene, use Nilfisk vacuums fitted with exhaust filters, for effective control of dustborne bacteria.
