FAQ (Frequently Asked Questions)
Q1: What’s the difference between IP44 and higher ratings?
A:
- IP44: Resists dust (>1mm) and water splashes (all directions). For harsher conditions (e.g., water jets), consider IP55+ models.
Q2: Can this W4E350-DA20-52 fan be speed-controlled?
A: Yes—use a triac-based AC motor controller (external) for RPM adjustment.
Q3: How does W4E350-DA20-52 compare to EC fans?
A:
✔ AC fans (W4E350): Higher initial torque, simpler control
✔ EC fans: More energy-efficient, variable-speed capable
Q4: What maintenance of W4E350-DA20-52 AC Fan is required?
A: None—sealed ball bearings are lubricated for life.
Q5: Is W4E350-DA20-52 suitable for outdoor use?
A: Limited—IP44 resists rain splashes but isn’t waterproof. For outdoor use, choose IP55+.
Q6: What’s the typical lifespan of W4E350-DA20-52?
A: 50,000+ hours under normal conditions (40°C ambient).
Why Choose the W4E350-DA20-52?
✅ Unmatched airflow (1935 CFM) for large-scale cooling
✅ Industrial durability (diecast aluminum + ball bearings)
✅ Thermal protection against overloads
✅ Certified safe (UL/CSA compliant)
Ideal for factory ventilation, HVAC, and heavy machinery, this fan balances power, reliability, and efficiency.
Need Higher Voltage?
For 230VAC operation, the W4E350-DA06-52 offers similar performance with lower current draw.
