Sanitary CI Series with Quick-Clean RotorRail™

The CI Series airlock features RotorRail™ technology, which facilitates disassembly and ensures accurate reassembly of the rotor and endplate. With no internal crevices and joints, the CI airlock’s quick-clean design saves time and effort when it comes to meeting industry standards for inspection and sanitization.

Standard features

Cast with superior solidification and metallurgy, the 304 or 316 stainless steel housing eliminates pits and dimples where contaminants could accumulate.
All rotor surfaces and product-contact surfaces of the housing are a No. 4 finish.
Cleaning, validation and inspection are easy with tool-less, single-step access to the rotor and internal surfaces.
RotorRail™ technology maintains rotor–endplate alignment during disassembly and ensures precise realignment during reassembly.
The Run-Clean™ design includes angled surfaces, rounded edges and factory-applied internal coatings to reduce material buildup in the housing.
Valves are available in seven heights (10” to 44”) and seven square-flange sizes (6” to 18”).
CNC-machined components and housing provide precision tolerances, eliminate axial shaft movement and extend maintenance cycles.
The outboard-bearing design protects bearings in high-temperature and high-PSIG applications, as well as removes bearings from the direct path of damaging contaminants.
CI-Series airlocks easily manage pressure differentials up to 15 PSIG.
CI-Series airlocks deliver excellent performance in applications up to 500°F.
Every CI-Series airlock features an 8-vane rotor with beveled tips and sides.

Optional features

304, 304L, 316, 316L or 2205 cast stainless steel valve housing.
