CLEARANCE POCKETS

Custom-designed or reconditioned to fit your operating conditions.


Most high-speed units run unattended and operating conditions continually change. With CECO Automatic Machined Clearance Pockets the units can be kept closer to 100% load. These pneumatically-actuated valve cap unloaders allow you to change load and capacity with varying operating conditions while maintaining high compressor efficiency. Custom-designed and exactly tailored to your size requirements, our machined pockets can be fitted with pneumatic actuators to open and close with a low-pressure air or gas signal and comply with API 618.

For shorter delivery and exact volume, the pockets are made from machined parts – not castings. They are tested to 1.5 times the maximum working pressure. We can assist you in determining the optimum cubic-inch-size pocket required to satisfy your operating conditions.
