The Wacker Neuson Pressure Switch is a genuine OEM component designed for the CUB200, CUB300, and CUB300HD series portable indirect fired air heaters. As a direct factory replacement, this pressure switch restores correct combustion air monitoring to your heater, ensuring safe and consistent operation on the job. Wacker Neuson OEM parts are manufactured to the same specifications as the original components installed at the factory, so you can be confident in fit and function across the supported CUB series models.
Key Features
- OEM-Calibrated Switching Threshold — Manufactured to the exact pressure setpoint specified for CUB series heaters, ensuring the control circuit responds correctly under real operating conditions.
- Drop-In Replacement — Matches the original mounting configuration and electrical connection of the factory-installed switch, allowing straightforward installation without modification.
- Broad CUB Series Compatibility — Fits the CUB200 Portable Indirect Air Heater (Diesel), CUB300 Portable Indirect Air Heater (Diesel w/37 Gal Tank), and CUB300HD Portable Indirect Fired Air Heater Heavy Duty models.
- Sustained Heat Output — A properly functioning pressure switch keeps the burner and airflow system in sync; a failed switch can cause nuisance shutdowns or prevent the heater from firing altogether, cutting heat delivery when it matters most.
- Fuel System Safety Compliance — The pressure switch is a critical safety-circuit component that monitors combustion air conditions and shuts down the burner if pressure falls outside safe limits, protecting the heater and the surrounding work area.
A pressure switch in an indirect fired air heater monitors the airflow or combustion chamber pressure to confirm that the burner has the correct operating conditions before allowing ignition or continued fuel delivery. When pressure is within the acceptable range, the switch closes its circuit and permits normal heater operation. If the switch fails or wears out, the heater's control board may prevent startup, trigger repeated lockouts, or fail to detect a loss of airflow — all of which result in inconsistent heating or a heater that will not run at all.
