1.5 inch Donaldson M045123 - Spark Arrestor

A 1.5-inch (38mm) inlet/outlet spark trap for fire prevention in exhaust systems. Constructed from high-grade alloy steel, it meets critical spark suppression standards for safe operation in combustible environments like forests or dry fields.
1.5 inch Donaldson M045123  Spark Arrestor 

• Part Number: M045123

• Description: Spark Arrestor / Spark Trap

• Primary Function: To prevent hot carbon particles (sparks) and embers from exiting an exhaust system, thereby mitigating fire hazard risks.

Key Technical Specifications

Typical Applications

This is a medium-duty arrestor suitable for:

• Stationary Engines: Generator sets, pumps, compressors.

• 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

1. Verification: Double-check the connection type (e.g., NPT, flanged) and thread pitch against your exhaust pipe before purchasing.

2. 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.

3. 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.

4. 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).

5. 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.
