Planning for safety
From the design phase to the BHA application of all filter subs, we keep safety our first priority.
All of our subs are only 5-1/2 feet long for easy and safe handling on the rig floor.
We also designed a filter that can be placed in and taken out of the sub with ease.
We offer filter subs in all sizes and connections as well as in non-magnetic and steel, giving you the ability to place in multiple locations in the BHA or above. Research on flow simulated software plus extensive and continuing studies give us the ability to provide one of the best products in the drill string used for filtration today. Read more..
