Daikin-McQuay 349956812 Control
The Daikin-McQuay 349956812 Control is a precision-engineered differential pressure switch designed specifically for dirty filter alarm applications in commercial HVAC units. As an authentic OEM Daikin replacement part, this pressure control switch ensures your air handling units maintain design-spec airflow by monitoring the pressure drop across the filter bank. For seasoned technicians, this is a non-negotiable component to prevent static pressure spikes that lead to premature blower motor wear and decreased system efficiency. The 349956812 utilizes a binary signal to trigger an alert at the building automation system (BAS) or a local indicator the moment the filter differential pressure reaches its calibrated setpoint, eliminating the guesswork of schedule-based maintenance. This HVAC pressure sensor is compatible with various legacy and modern McQuay and Daikin Applied systems, providing a reliable dirty filter indicator for high-performance service contracts.
Key Benefits
- Ensures HVAC airflow optimization by providing real-time notification of clogged filtration media.
- Maintains indoor air quality (IAQ) and protects system components from the strain of high static pressure.
- OEM compatibility ensures seamless integration with Daikin and McQuay control logic without field modifications.
- Robust construction specifically calibrated for the low-pressure environments typically found in filter monitoring.
Common Questions
Does this control work with variable air volume (VAV) systems?
While this binary switch is ideal for constant volume systems to trigger a dirty filter alarm, technicians should verify the specific pressure setpoint for VAV applications where airflow fluctuations can affect differential readings.
What is the primary function of the 349956812?
It serves as a safety and maintenance control that monitors air pressure before and after the filter, closing a circuit to signal that the filter is loaded and requires replacement.
Can this replace third-party differential pressure switches?
Using this original equipment manufacturer part is the preferred method for maintaining the integrity of Daikin-McQuay equipment, ensuring the electrical ratings and pressure ranges match the factory sequence of operations.
