Wacker Neuson 5000181913 Inlet Plug Plate

The Wacker Neuson Inlet Plug Plate is a genuine OEM component designed for the HI750, HI900, HI1000, and HI260 series indirect fired air heaters. As a factory-sourced part, it matches the original specifications of the heater it replaces, ensuring a correct, consistent installation every time. This plate is confirmed to fit a wide range of HI-series configurations including diesel, natural gas, LP, and dual-fuel DGM models, as well as skid-mounted and trailer-mounted variants across the HI750, HI900, and HI1000 lines.

Key Features

• Genuine OEM Construction — Sourced directly from Wacker Neuson, this inlet plug plate is manufactured to the same dimensional and material standards as the original, ensuring a proper seal at the inlet port without improvisation.
• Direct-Fit Replacement — Designed to drop into the same mounting position as the factory part, aligning with existing fastener points on the heater housing with no rework to surrounding components.
• Broad HI-Series Compatibility — Fits HI750 (gas, diesel, DGM), HI900 (diesel, gas, DGM), HI1000 (diesel, gas, DGM), and HI260 indirect air heaters across skid, trailer, and surge brake configurations.
• Maintains Combustion Chamber Integrity — A correctly seated inlet plug plate prevents unwanted airflow or exhaust bypass at the inlet, keeping combustion efficiency and heat output consistent across operating conditions.
• Fuel System Safety Relevance — On indirect fired heaters operating with diesel, natural gas, or LP fuel, a secure and correctly fitted inlet plug plate supports proper fuel-air containment, reducing the risk of uncontrolled gas migration near combustion components.

The inlet plug plate seals the inlet port on an indirect fired air heater, blocking off unused or service openings in the heater's combustion or air-handling section. On indirect heaters, maintaining a sealed airflow path is critical — the heat exchanger must channel combustion gases completely away from the output air stream. A damaged, missing, or incorrectly fitted plug plate can allow air leakage that disrupts burner performance, reduces heating efficiency, or allows exhaust gases to enter areas of the unit where they should not be present. Replacing a worn or failed inlet plug plate restores the sealed integrity the heater depends on to operate safely and efficiently.
