Lennox 18Y93 Relay Kit 30067439-890 Key Benefits: Precise Pressure Calibration:

Key Benefits: Precise Pressure Calibration: Factory-set at 165Op/130Cl to ensure accurate compressor protection without the need for field adjustments

eliminating the risk of bypass leaks or improper drainage slopes during HVAC condensate pan replacement

providing technicians with a reliable solution for restoring system timing sequences

High-Durability Metallurgy: Stainless steel ball and stem prevent premature wear and chemical degradation compared to chrome-plated alternatives

as the artificial heat will skew the readings and degrade system performance

Lennox 18Y93 Relay Kit 30067439-890 Key Benefits: Precise Pressure Calibration:The Lennox 18Y93 Delay Relay Kit is a critical OEM component designed to regulate blower motor timing and facilitate efficient sequence operations in commercial HVAC equipment. As a primary delay relay kit, the 18Y93 provides a fixed 45 second blower on delay and a 150 second blower off delay, ensuring the heat exchanger is adequately warmed before airflow begins and residual heat is fully utilized post cycle. This HVAC time delay relay is the factory
