Qualified engineers are on hand to survey your site and put together the
best solution for your individual application.
Modular design
Different applications produce different types
and amounts of particulates and gases so a variety of filters and extractors is required. Purex provide the correct combination of components
to be implemented to do the job correctly. These can include:
Reverse airflow
As soon as air is drawn into a Purex machine, its direction of flow is diverted through 90 degrees. This throws larger particles out of the air stream and into a collection tray or pre-filter bag, thus preventing them from entering the main filter and prematurely reducing its life span.
The Reverse Airflow system has an added benefit. When vapour is present in the extract air (e.g. from lasing PVC) it will condense into a liquid inside the filters and drip downwards. In other top loading fume extractors this liquid could potentially drip onto any electrics and motors below to cause a hazard. In Purex systems any liquid is collected in a tray or absorbant pad.
Pre-filters
Inexpensive pre-filters are used to collect larger particles over 1-3 microns to prevent them from prematurely blocking the main filters.
Several options are available for processes that produce large quantities of dust; high capacity pre-filters, various types of bag filter and Cascade boxes.
Main HEPA (High Efficiency Particle Air) filters
The filters used in Purex fume extractors have been designed to offer
many unique features.
Filter Features:
- Maximum airflow - The filter design allow the use of high pressure blowers
to overcome the resistance to airflow through a filter for much
longer as the filter begins to block. This means the filters last
longer.
- Guaranteed unburstable - By employing reinforcing.
- Design - The size, design and production technique gives more filter media surface area than in many other filters, thus extending life span.
- Maximum filtration - In independent tests, these filters remove 99.997% of all particles above 0.3 microns and 95% down to 0.01 micron.
- Flow equalisation plates - Help to distribute the airflow over the filter media and make the whole filter more robust.
- Precise and rigid construction - Helps ensure that no fumes are allowed to pass around the filter and escape into the workplace.
