The Wacker Neuson is a genuine OEM Differential Pressure Gage designed for the HI750 and HI900 series mobile indirect fired air heaters. As a factory-sourced component, it meets the exact specifications set during original manufacture, ensuring accurate pressure readings and proper integration with the heater's monitoring system. This part covers a broad range of HI750 and HI900 configurations including diesel, natural gas, LP, skid-mounted, and surge brake variants. When you need a direct, verified replacement, the is the part to specify.
Key Features
- Calibrated OEM Accuracy — Sourced directly from Wacker Neuson, this gage delivers the precise differential pressure measurement range the HI750 and HI900 heater systems are engineered around — no guesswork on calibration or scale.
- Drop-In Replacement — Matches the original port connections and mounting configuration, so installation goes straight in without reworking fittings or brackets.
- Broad Series Fitment — Compatible across HI750G, HI750D, HI750GM, HI750GMHD, HI900D, HI900G, and HI900DGM model families, including skid-mounted and surge brake variants.
- Protects Heater Performance — Accurate differential pressure monitoring keeps airflow and combustion efficiency within spec; a failed or drifted gage can mask filter blockages or airflow restrictions that degrade heat output.
- Operational Safety Relevance — In indirect fired heating equipment, monitoring differential pressure across the heat exchanger is a critical safety function — using a correctly rated OEM gage ensures the system responds accurately to potentially hazardous conditions.
A differential pressure gage measures the difference in pressure between two points in a system — in this application, typically across the air filter or heat exchanger in the indirect fired heater. This reading tells the operator whether airflow is unrestricted or whether a blockage is developing, which directly affects combustion efficiency and safe heat output. When the gage fails or reads inaccurately, filter restrictions and airflow problems can go undetected, leading to reduced heater output, overheating, or unsafe operating conditions.
