All about Cartridge & Bag Filter

• A surface filter is useful when concentrations are above 5 mg/m3, while for below 0.5 mg/m3 concentrations, depth filters are more preferable.

• Surface filters can be cleaned or backwashed very easily while depth type filters need to be disposed when clogged.

• Normally, Cartridge filter can be surface type filter or depth type filter.

• In surface filters, particles are blocked on the filter surface while particles are captured in depth-type filters and contaminant through the thickness of the medium.

• For filtering sediment of similar sized particles, surface filters works best.

• In comparison with pleated surface filters, depth filters have the advantage of depth but have a restricted surface area.

• If the filter surface size is increased, it allows higher flows and increase dirt holding capacity as well as the filter last for a long time.

• Mostly, Bag filters are surface type filters.

• Normally, Cartridge filters are specifically designed disposable means it needs to be replaced when the filter is clogged.

Features: 

• Compact Design and Low weight

• Low pressure drop across the filter

• Adequate strength of element and housing

• Permits rapid servicing i.e. ease of cleaning or replacing the element

• Component or parts suitable for and compatible with hydraulic fluid concerned.

• Interchangeability of component with another of same type.

• Energy Efficient

• Surface filtration prevents micron particles to penetrate

• Low installation and construction cost
