Patterson-Kelley 86-8335-0170 Air Flow Switch
The Patterson-Kelley 86-8335-0170 Air Flow Switch is a critical safety and operational component designed for high-performance commercial boilers and water heaters. As an OEM airflow switch replacement, this unit utilizes a sensitive differential pressure diaphragm to detect proper combustion air or exhaust flow. It is engineered to interface directly with Patterson-Kelley industrial air flow switch control systems, ensuring the burner only fires when safe airflow thresholds are met. This HVAC airflow sensor features a durable housing and an adjustable diaphragm airflow switch mechanism, allowing technicians to calibrate the set point to specific static pressure requirements of the venting system. For contractors maintaining commercial HVAC monitoring devices, using this Patterson-Kelley 86-8335-0170 Air Flow Switch ensures precise compatibility and maintains the original equipment’s engineered safety sequences, preventing common pressure-related lockout issues in demanding mechanical environments.
Key Benefits for Technicians:
- System Protection: Prevents unsafe ignition cycles by accurately monitoring differential pressure across the heat exchanger or blower.
- Contractor-Grade Durability: Constructed with industrial materials to resist vibration and thermal stress common in boiler rooms.
- Field Calibration: Features an adjustable set point to accommodate various venting lengths and field conditions without replacing the entire assembly.
- Direct OEM Fit: Eliminates the need for field modifications or generic brackets, ensuring rapid installation and reliable terminal connections.
Common Questions:
How do I calibrate the set point on this air flow switch?
The switch includes a calibration screw that adjusts the diaphragm tension. Use a digital manometer to measure the system's actual pressure and set the switch to trip at the manufacturer’s specified minimum inches of water column (WC).
Can this switch be used for both positive and negative pressure applications?
Yes, the dual-port design allows for differential pressure sensing, making it suitable for monitoring supply air, exhaust draft, or pressure drops across filters and coils.
What causes a "no air flow" error if the blower is running?
Typically, this is caused by a ruptured internal diaphragm, clogged sensing tubes, or an incorrectly adjusted set point. Replacing the worn component with a genuine Patterson-Kelley 86-8335-0170 restores factory-spec reliability.
