The Wacker Neuson Cover is a genuine OEM component designed for the HI750 and HI900 series indirect-fired air heaters. As a factory-sourced part, it is manufactured to the exact specifications of the original, ensuring a direct, correct-fit replacement for a wide range of HI750 and HI900 configurations — including diesel, natural gas, LP, and DGM surge-brake variants. Whether you are servicing a skid-mounted unit or a mobile heater, this cover matches the original in form and function across the full HI750 and HI900 model lineup.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original material and dimensional specifications, ensuring the cover seats, seals, and fastens exactly as the factory-installed unit.
- Drop-In Replacement — Engineered to match the original mounting points and profile on HI750 and HI900 series heaters, allowing straightforward reinstallation without modification.
- Broad HI-Series Fitment — Compatible across HI750G, HI750D, HI750GM, HI750GMHD, HI900D, HI900G, and HI900DGM variants, covering diesel, natural gas, LP, skid-mounted, and surge-brake configurations.
- Protects Internal Components — A properly fitted cover shields critical heater internals from jobsite debris, moisture, and physical damage, maintaining heater output and heat-exchanger integrity over extended use.
- Verified Part Number — Part number 5000181881 cross-references directly to the HI750 and HI900 series, giving you confidence you are ordering the correct cover for your specific unit.
The cover on an indirect-fired air heater serves as a protective enclosure for the unit's internal heat exchanger, burner assembly, and associated components. It shields these parts from environmental exposure — including moisture, dust, and physical impact — that can degrade performance or cause premature failure of sensitive components. When a cover becomes cracked, warped, or damaged, it can compromise the integrity of the heater's housing, leading to heat loss, contamination of internal components, or unsafe operating conditions in cold-weather construction and temporary heating applications.
