TWIN FILTER - CARTRIDGE AND BAG FILTER UNITS

 

CARTRIDGE AND BAG FILTER UNITS

Cartridge and Bag Filter Units are the most commonly used units in the filtration of fluids for Oilfield Services. The units offer the flexibility in a wide range of applications from polishing after DE (Diatomaceous Earth filter) to hydrocarbon removal. The units can accommodate a wide range of cartridge and bag configurations depending on removal, flow, pressure and retention requirements.

Twin filter has also developed a combination unit, which offers the option of using filter cartridge and/or filter bags in the same unit without the need for tools, making it a “field friendly” unit.
