Description

Sullair Sullicon Control External Diaphragm Kit Replacement – 250020-028

Sullair Sullicon Control Parts Kit Replacement (250020-028) is a factory-defined service kit that includes the external diaphragm and associated service components used on compatible Sullair stationary rotary screw air compressors with Sullicon control systems.

This external diaphragm is part of the Sullicon control assembly and helps regulate pressure and control signals within the compressor’s pneumatic control system. The diaphragm flexes to open and close passages, helping manage transitions between load and unload states and supporting stable pressure response.

This replacement parts kit is installed as a complete service assembly and is commonly used during corrective maintenance when the existing external diaphragm shows signs of wear, cracking, hardening, or inconsistent response to pressure changes.
