Comparing numerous air pollution control devices, the dry fabric filter is by far the most efficient and reliable. Contrary to other filtering methods, variations in dust loading or air volume will not change the outlet conditions of a well-designed dry fabric collector. Of the types of dry fabric filters, the pulse-jet is far superior since it allows the use of highly efficient felt filter fabric.
The dust is collected on the outside of the filter bags. At regular intervals, a burst of
metered compressed air is injected through the PULSE collector parabolic velocity stacks to dislodge the agglomerated dust which falls into the hopper.
Maximum filtering efficiency is attained by using top quality needled felt media of appropriate weight and construction. a full range of natural and synthetic felts are available to suit specific requirements; fibreglass, polyester, nylon, Nomex, etc. All bags are accessed from the top of the collector, eliminating the need for dirty side entry to change and service bags.
