Compliance
Meets industry spark suppression standards (e.g., USFS Standard 5100-1c, SAE J350)
Mobile Equipment: Forestry machinery, forklifts, tractors, and other internal combustion engines operating in combustible environments (sawmills, dry fields, forests).
Industrial Equipment: Boilers, incinerators, or any process exhausting hot particulate matter.
Important Considerations for Purchase & Installation
Verification: Double-check the connection type (e.g., NPT, flanged) and thread pitch against your exhaust pipe before purchasing.
Compatibility: Ensure the 1.5" inlet size matches your exhaust system diameter. Do not use reducers/adapters that significantly restrict flow unless engineered for it.
Maintenance: Spark arrestors require periodic cleaning (e.g., tapping to dislodge carbon buildup) to prevent excessive back pressure. The M045123 is likely a serviceable centrifugal/cyclonic type.
Regulations: Confirm that the specific "industry standards" it meets are acceptable for your local regulations and insurance requirements (e.g., USDA Forest Service approval for certain machinery).
Source: Purchase from an authorized Donaldson distributor or reputable heavy equipment parts supplier to ensure you receive a genuine, compliant part.
In summary, the Donaldson M045123 is a robust, industry-standard spark arrestor designed for engines with a 1.5" exhaust outlet, providing critical fire prevention for operation in hazardous areas. Always consult the official Donaldson documentation or a qualified technician for final installation and compatibility checks.
