Batch centrifugal screens Ferguson Perforating supplies batch centrifugal screens for all major types of centrifuges worldwide. Both round hole and slotted screens are available in stainless steel or brass. Our slotted screen has a higher open area than comparable screens that other suppliers offer. Precision aligned locklap joints allow easy insertion during installation. Mud filter screens We have developed a mud filter screen with an improved hole pattern. Our screens have a uniform flatness, have straight and parallel long sides, and a flatter working surface with minimal residual stress. All these characteristics together make the screens easier to install, extends the service life and reduces failure due to cracking. Our focus is on providing you screens that lower your operating cost.
