Axial Fans (Industry Standard) | General ventilation, low-pressure systems | Sleeve bearings (ISO 5593 compliant), 12V DC (IEC 60038), Plastic blades (ASTM D638) | Affordable, compact, widely compatible with basic systems | Short lifespan (1-2 years), lower efficiency, limited voltage flexibility |
EBM-PAPST 4184NX (Base) | Office cooling, small HVAC systems | Ball bearings (ISO 5593, reduces friction by 40%), 24V DC (IEC 60038), Plastic blades (ASTM D638) | 43 dBA (quieter than a refrigerator), energy-efficient, 1-year warranty | Plastic blades degrade in harsh environments, limited voltage options |
EBM-PAPST 4184NX (Advanced) | Industrial cooling, heavy-duty equipment | Stainless steel bearings (ISO 5593, ▲ lifespan +50%), 48V DC (IEC 60038, ▲ voltage flexibility), Aluminum blades (ASTM B209, ▲ corrosion resistance) | 3-year warranty (▲), handles extreme temperatures, 35 dBA (▲ quieter) | Higher cost, heavier weight, requires专业 installation |
Centrifugal Fans | High-pressure duct systems, industrial exhaust | Cast aluminum housing (ISO 9001), 230V AC (IEC 60038), 115 dB noise (ISO 3744) | Delivers 1000+ CFM airflow (▲ pressure capacity), durable construction | Noisier (▲ loud), bulky design, higher power consumption |
Inline Fans | Ducted HVAC systems, air purifiers | 24V DC (IEC 60038), 120 mm diameter (ISO 2848), 0.5W power (IEC 60038) | Space-saving design (▲ compact), low energy use, easy to install | Limited airflow (▲ lower CFM), incompatible with high-pressure needs |
EBM-PAPST Competitor Fan | Commercial ventilation systems | Sleeve bearings (ISO 5593), 24V DC (IEC 60038), Steel blades (ASTM A36) | Steel blades (▲ stronger), 2-year warranty, 45 dBA | Higher noise than EBM-PAPST, no advanced voltage options |
