Wacker Neuson 5200023159 Secondary Air Filter

The Wacker Neuson Secondary Air Filter is a genuine OEM component designed for the HIF 690 Flameless Air Heater series, including both the standard and Kubota Engine variants. As a factory-sourced part, the is manufactured to the exact specifications required by Wacker Neuson for these machines, ensuring a direct, trouble-free installation. This is the correct OEM replacement when the secondary filter element on your HIF 690 is due for service or has become restricted. Keeping the secondary air filter in good condition is essential to protecting the heater's engine and combustion system from contaminant ingestion.

Key Features

• OEM Filtration Media: — Manufactured to Wacker Neuson's specified particle-capture rating for the HIF 690, so the filter performs exactly as the machine's air intake system was engineered to expect.
• Drop-In Service Replacement: — Sized and ported to match the factory air filter housing on the HIF 690, allowing straightforward swap-out during scheduled maintenance without adapting or trimming.
• Confirmed HIF 690 Fitment: — Verified for both the standard HIF 690 Flameless Air Heater and the Kubota Engine variant, covering the primary configurations in the HIF 690 line.
• Engine and Combustion Protection: — A functioning secondary filter catches fine particulates that bypass the primary element, preventing premature wear to internal engine components and maintaining consistent combustion air quality.
• Combustion Air Quality Compliance: — In heater applications, clean, correctly filtered combustion air directly affects flame stability and emissions output — using the specified OEM filter helps the unit operate within its designed parameters.

The secondary air filter sits downstream of the primary filter element in the machine's air intake path, acting as a final barrier against fine dust and debris before air reaches the engine or combustion chamber. In demanding jobsite environments — particularly where dusty or particulate-laden air is common — the secondary filter carries significant responsibility for protecting internal components. When this filter becomes clogged or damaged, restricted airflow can cause hard starting, loss of heat output, elevated exhaust temperatures, and accelerated engine wear, making timely replacement a critical part of routine heater maintenance.
