Cartridge flow direction is from outside-to-in. Water is repelled by the hydrophobic separator medium on the cartridges' outside surface. Hydrocarbon fluids, on the other hand, easily pass through and exit the separator cartridge.
DHA Filter carries cartridges with three different types of repelling media:
Teflon Coated Screen (TCS) Cartridges
-by far, the most popular type of separator cartridge.
With proper cleaning and inspection they can be reused over several coalescer cartridge change out cycles. TCS cartridges generate considerably less static charge than pleated paper cartridges. These features have made them the preferred choice for aircraft fueling applications.
Pleated Paper Cartridges
-cannot be reused and are replaced at every coalescer cartridge change out. They are often used with diesel and other fuel oils which may contain materials that adhere to TCS cartridges and cannot be cleaned off.
Synthetic Media Cartridges
-can be cleaned a maximum of two times. They are lower in price than TCS cartridges and are intended for customers who do not want to take the time to clean separators.
