Cleveland Controls DDP-106-216 Switch

The Cleveland Controls DDP-106-216 is a professional-grade differential air pressure switch designed for critical monitoring in HVAC units and energy management systems. This unit features dual-switching action, utilizing two independently adjustable SPDT snap-acting switches mounted on a common foot bracket. This configuration allows technicians to establish a precise adjustable deadband for control circuits that require distinct high and low actuation points. Each sensing element is housed in a plated enclosure containing a diaphragm and a calibration spring, ensuring reliable airflow proving across diverse environmental conditions. With a pressure switch set point range adjustable up to 2" w.c., the DDP-106-216 provides the granular control necessary for duct heater protection and complex air handling sequences.

Engineered for versatility, the HVAC duct pressure sensor includes a common high-pressure sample connection and two individual low-pressure connections, all of which accept 1/4" OD metallic or rigid plastic tubing via integral compression ferrules. The electrical rating of 15 amps non-inductive at 277 VAC ensures compatibility with standard industrial air flow switches and heavy-duty HVAC controls. For optimal accuracy and to maintain the lowest specified operating set point, the device must be surface-mounted with the diaphragm in a vertical plane. This rugged Cleveland Controls air switch is a standard choice for contractors looking to replace worn-out differential sensors in commercial air handlers or cooling towers where multi-point sensing is required.

• Independent Dual Switching: Two separately adjustable SPDT switches allow for complex "high-low" or lead-lag control logic.
• Precision Differential Sensing: Capable of measuring sensitive air pressure differentials with a high degree of repeatability.
• Rugged Industrial Build: Plated housings and high-quality diaphragm materials designed for 100,000+ cycles at maximum electrical load.
• Standardized Connections: Features 7/16"-24 UNS threaded connections with nuts and ferrules for secure 1/4" OD tubing attachment.
• Versatile Application: Ideal for proving airflow in ovens, duct heaters, and advanced building automation sequences.

Can I use the DDP-106-216 to monitor two different pressure sources?
Yes, the dual-switch design allows you to monitor two separate low-pressure sources against a common high-pressure reference, providing two independent relay outputs.

What is the best mounting orientation for this switch?
To ensure the calibration remains accurate, always mount the unit with the diaphragm in a vertical plane. Avoid mounting with sample line connections facing upward to prevent moisture or debris accumulation.

Does this switch work with plastic tubing?
The integral compression fittings are designed for 1/4" OD rigid or semi-rigid tubing, including copper, aluminum, or standard industrial plastic lines.
