Double cylinder sand filter is a kind of equipment used for ground test. 

It is used for well flushing and sand removal after fracturing. 

It can safely filter the fracturing sand of large- scale fracturing, fillter and calculate the sand production of formation,and effectively reduce the damage to downstream ground equipment.

The equipment is integrated into a skid and adopts a double cylinder structure. 

The filter cylinder switch is simple. The double filter cylinders can be used alterately and continuously. 

The sand discharge mode can choose to lift up or use the choke valve to discharge sand online.

The equipment is suitable for sand removal in low viscosity oil wells and gas wells, with limited capacity to handle viscous liquids.
