CAUTION
The nitrogen generator will be permanently damaged by oil vapor or aerosol from
a compressor. The damage will not be repairable and will require replacement of
the product
CAUTION
Oil-free compressors may still deliver oil (hydrocarbons) to the nitrogen generator
if the inlet air is contaminated. It is essential that clean air, free of hydrocarbons
and acid, is supplied to the inlet of the compressor. A three-stage filter is used
between the compressor and nitrogen generator to protect the nitrogen
generator from any remaining contamination.
CAUTION
Even when an oil-free compressor is used the filter unit incorporated in the
nitrogen generator must be used.
