CAT Air Filter 586-5323, 494-6995 is Suitable for Caterpillar C32 Engine.

# Genuine Cat Air Filter: 586-5323 & 494-6995 for Caterpillar C32 Engines   Genuine Cat Air Filters 586-5323 and 494-6995 are OEM-engineered filtration components exclusively designed for Caterpillar C32 diesel engines—delivering industry-leading air purification to protect critical engine internals (pistons, cylinders, turbochargers) from harmful contaminants like dust, dirt, and debris. By ensuring clean, unrestricted airflow, these filters optimize combustion efficiency, reduce premature wear, and maintain the C32 engine’s rated power output and fuel economy, even in high-pollution environments (e.g., construction sites, mining operations, marine bulk handling).   ## 1. Core Specifications   | Parameter                | Details                                                                 | |--------------------------|-------------------------------------------------------------------------| | Part Numbers             | 586-5323 (Primary OEM Air Filter); 494-6995 (Alternate OEM Equivalent)  | | Application              | Caterpillar C32 diesel engines (Industrial, Marine, GenSet, Petroleum)  | | Filter Type              | Heavy-Duty Pleated Air Filter (for engine intake air purification)     | | Filtration Efficiency    | Captures ≥99.9% of particles ≥3 microns (per Cat’s ISO 16889 testing)   | | Operating Temperature    | -40°C to 120°C (suitable for extreme hot/cold operating conditions)     | | Compatibility            | 100% OEM-matched to C32 engine air intake housing—no modifications needed for installation | | Warranty                 | Cat Genuine Parts Warranty (12 months from installation, per Cat’s terms) | ## 2. Design & Performance Advantages   - **Multi-Layer Filtration Media**: Constructed with a durable, pleated synthetic-cotton blend media that balances high dirt-holding capacity (extends service intervals) and low airflow restriction (prevents power loss from intake starvation). The media’s dense structure traps fine particles while resisting clogging from oil or moisture.   - **Heavy-Duty Housing/Seal**: Features a rigid, impact-resistant plastic or metal frame (varies by part number) and a premium rubber seal around the filter edge. This seal eliminates “bypass air” (unfiltered air leaking into the engine) and withstands vibration from heavy machinery or marine propulsion.   - **OEM Fit Precision**: Engineered to match the exact dimensions of the C32’s air intake system—ensuring seamless installation into the factory air cleaner housing. No adapter plates or custom modifications are required, reducing maintenance time.   - **Engine Protection Focus**: Tested to Cat’s strict durability standards, including exposure to dust, temperature cycles, and mechanical stress. This ensures the filter maintains performance over its service life, preventing abrasive wear to turbochargers (a common failure point in unfiltered C32 engines).   ## 3. Application Scope   These air filters are approved for all C32 engine-powered equipment across key sectors, where clean air is critical to reliability:   - **Industrial**: C32-powered crushers, screeners, heavy-duty loaders, and industrial pumps (common in mining, construction, and aggregate processing).   - **Marine**: C32 marine propulsion engines (yachts, workboats, offshore support vessels) and auxiliary generators—where salt air and coastal dust require robust filtration.   - **Power Generation**: C32 generator sets (GenSets) for prime/standby power (data centers, remote industrial sites, emergency backup systems).   - **Petroleum**: C32 engines in oilfield equipment (drilling rigs, well-servicing units) exposed to dust, sand, and hydrocarbon-based contaminants.   ## 4. Maintenance & Replacement Guidelines   - **Service Interval**: Recommended replacement every 500–1,000 operating hours (varies by environment—shorter intervals for dusty/mining applications, longer for clean marine or indoor GenSet use). Always inspect the filter monthly for visible dirt buildup or damage.   - **Replacement Steps**: 1) Turn off the C32 engine and relieve intake system pressure; 2) Remove the air cleaner housing cover (typically secured by clips or bolts); 3) Replace the old filter with a genuine 586-5323/494-6995 unit, ensuring the rubber seal is properly seated; 4) Reattach the housing cover and verify no air leaks.   - **Core Disposal**: Dispose of used filters in compliance with local environmental regulations (most are recyclable via industrial waste programs).   ## 5. Critical Note on Part Numbers   586-5323 and 494-6995 are **fully interchangeable for all C32 engine models**—both meet identical OEM performance and fitment standards. The part number difference reflects minor variations in manufacturing sourcing (e.g., regional supplier batches) or housing material (plastic vs. metal, depending on application), not functional or filtration differences.   For exact replacement timing, availability, or technical support (e.g., custom filtration for extreme environments), contact an authorized Cat dealer with your C32 engine’s serial number and equipment application.
