The Wacker Neuson Filter Seal Kit is a genuine OEM component designed for the HD 50, HD 70, and HI 90 indirect-fired air heaters. As a direct factory replacement, this kit ensures the filter housing maintains a proper airtight seal, keeping combustion airflow clean and controlled across all supported heater models. Sourced directly from Wacker Neuson, part number delivers the exact material grade and dimensional tolerances required for a correct, lasting installation. If your heater is showing signs of air leakage, contamination ingress, or reduced heating efficiency, this kit addresses the root cause at the filter connection.
Key Features
- OEM Sealing Material Grade — Genuine Wacker Neuson seals are manufactured to the precise compression and temperature tolerances required for indirect-fired air heater filter assemblies, where heat cycling and airflow pressure demand consistent seal integrity.
- Direct Filter Housing Fit — Engineered to locate and seat correctly within the filter housing of supported heater models, restoring the original clamping surface without shimming or adjustment.
- Confirmed Fitment: HD 50, HD 70, and HI 90 Heaters — Verified for use across the HD 50, HD 70, and HI 90 indirect-fired air heater models, covering a range of Wacker Neuson's portable heating lineup.
- Preserves Combustion Air Quality — A properly sealed filter assembly prevents unfiltered air from bypassing the filter media, protecting the burner and heat exchanger from particulate contamination that can shorten service life.
- Fuel System Integrity — On indirect-fired heaters, compromised filter seals can allow contaminants into the fuel-air circuit, potentially affecting burner performance and combustion safety. Replacing worn seals restores the barrier between the environment and the combustion system.
The filter seal kit serves as the sealing interface between the air filter element and its housing on indirect-fired air heaters. Its role is to prevent unfiltered ambient air — carrying dust, debris, and moisture — from bypassing the filter and entering the heater's combustion or fuel-air system. When these seals degrade through heat cycling, compression set, or physical damage, the filter loses its effectiveness, and contaminants can reach sensitive internal components. Replacing the seal kit at each filter service interval is a straightforward step that protects the broader heater system and ensures the unit continues to deliver clean, efficient heat output.
