Know the intended pairings
| Fan | Published application | Discuss with FumeCare |
|---|---|---|
| Fumeflow D250 | Designed to complement Smoothflow and SashDrive cupboards. | System duty, drive/control arrangement, support and discharge configuration. |
| Fumeflow TD250 | In-line centrifugal fan designed to complement Student cupboards. | Exact Student model, stack mounting, existing support and installation details. |
Identify what is already installed
For a replacement enquiry, provide photographs of the fan label, cupboard identification and any accessible drive or controller label. Include the asset number and site location. Do not access a roof or open an electrical enclosure just to collect information; explain what is not safely available.
The D250 has an inverter-based arrangement that can support SashDrive control. The TD250 uses a direct-drive, stack-mounted design for the Student package. Those differences make confirmation of the complete arrangement important before ordering.
Give the selector a system brief
- Cupboard model, intended use and current operating requirements.
- Known duct size and route, with drawings where available.
- Existing test or commissioning information and any measured airflow data.
- Power supply and control information from available records.
- Mounting, maintenance access and noise concerns.
If the fan is part of a new system, ask who will establish the required airflow and system resistance and select the operating point. If it replaces a failed fan, ask why the previous unit failed and whether any associated defects need attention. Repeating a model number is not a full review of the system.
Agree what happens after selection
Confirm the scope for supply, mounting, electrical and control work, system checks and handover. Ask which drawings and performance information apply to the selected unit. Check the exact document title: an old file name or copied performance sheet may not identify the installed model reliably.
We also make the D65 for chemical-storage-cabinet ventilation. That is a separate application; do not substitute it into a fume cupboard project on the basis of availability or size. Explain the extraction task first so the discussion follows the correct product family.
For an initial enquiry, “Student cupboard, existing TD250 label attached, replacement following a reported fault” is more useful than “250 mm fan required”. Add the site constraints and service history for a better assessment.
