Frequently Asked Questions
- Q: Does this fan come with a power cord?
- A: No. It has a terminal block for hardwiring.
- Q: Can I use it with 240V?
- A: No. Rated voltage is 85-132V AC only.
- Q: How loud is the alarm?
- A: 85 dB at 1 meter – audible in most industrial settings.
- Q: Is the alarm adjustable?
- A: Trip point is factory-set, not user adjustable.
- Q: What if the fan fails within warranty?
- A: Contact us – we ship a replacement immediately.
- Q: Can I mount it horizontally?
- A: Yes, the bearings support any orientation.
- Q: Does it include a filter?
- A: No, but optional filter kit is available separately.
Selection Guide
- For small cabinets (< 50 L): one fan is enough.
- For high-ambient temps (> 50°C): consider adding a second fan.
- For silent environments: use with external speed controller.
- For safety-critical applications: always connect the alarm output.
- Spare parts: order extra fuse and mounting screws.
