7. Special options
Blastrac offers a few special options. On request we have got advanced solutions for working conditions were
the use of special equipment might be desired or required by law.
7.1 HEPA filter
The purpose of this option is to ensure clean air at the work space. This is achieved by using our high class
HEPA filter. The Blastrac HEPA filters can be ordered in filter class H13 or H14
Our HEPA filters are tested according to EN 1822:2009 and classified H13 or H14 to test result.
7.2 Difference vacuum gauge
A vacuum gauge measures the difference between the under pressure above the filters and inner filter house.
This readout indicates the degree of pollution of the filters, with this system you can always keep an eye on
the condition and pollution of the filters inside the dust extractor. It can also help you fine-tune the airflow
when precise adjustment is required for the job.
