We produce two types of drums:
Internal/external slit drum: medium is fed to the inside surface of the filter element.
External/internal slit drum: medium is fed to the outer surface of the filter element.
Please note that the JSC PO STRONG produces drums only, not the whole installation.
RFDV drums produced by JSC PO STRONG can withstand high flow rates at a high filtration degree (250 μm).
