01 / UNDERSTAND THE EQUIPMENT

Bring directed circulation to a defined temporary work zone

Bigfans’ XM mobile family is a guarded floor fan on a wheeled frame, intended to direct circulation where a fixed ceiling installation is unsuitable. XM15 and XM20 are listed at 1.5 and 2.0 m diameter with masses of 140 and 172 kg, making handling, floor space and cable routes important purchase decisions. The original image shows a guarded wheel and castors but supplies no brake specification, transport procedure or complete stability assessment.

The source lists XM20 motor power as 0.5 kW, while XM15 is printed as 0.5 W. That unit conflict must be resolved before approving an electrical budget; it is not silently corrected here. Claimed effective coverage near 300 m² and perceptible air beyond 30 m have no reviewed velocity map or test conditions. Select the unit against an actual working zone and obtain its current electrical, movement and guarding instructions.

Selection and application review

Map the directed airflow to the occupied zone

Issue working positions, aisles, obstacles and the intended fan direction. Obtain measured or selected air speeds at the required distances, rather than using 300 m² as a universal coverage guarantee. Define comfort without treating circulation as fresh-air exchange or a refrigeration load.

If a process generates contaminants, select extraction/ventilation separately. The source supplies no filter, contaminant removal or outdoor-air duty. Arrange the unit through an approved site assessment instead of assuming more airflow solves every work-zone problem.

Approve movement and floor restraint for the actual mass

At 140–172 kg, the assembly is a handled industrial unit, not an assumed hand-carried appliance. Obtain castor/brake, stability, permissible surface/slope and movement instructions. The photograph does not prove how it is locked or moved safely in the customer’s aisle.

Close footprint, access and guarding with the current assembly drawing. Define who relocates it and how the electrical connection is isolated and protected during movement. No universal clearance or stability limit is invented from the family image.

Resolve the power row and temporary electrical connection

Request written confirmation of XM15’s 0.5 W entry and the selected motor/controller schedule. Both rows share a 1.8 A / 220 V reference but no phase/startup or full operating-input definition. Do not convert an ambiguous motor entry into a verified consumption or energy-saving figure.

Obtain cable, protective, control and environmental requirements for the actual work area. The page supplies no whole-assembly ingress or hazardous-area rating. PMSM and gear-free language does not establish universal electrical suitability or zero maintenance.

Accept one mobile configuration and its service instructions

Approve the current model, guarding, movement/locking procedure and electrical documents. Verify direction/speed, controls, restraint and actual occupied-zone delivery at the agreed operating range. Record how the guard/wheel can be cleaned and inspected without guessing a lubrication interval.

Supplier reliability and maintenance-free adjectives are not independently tested life guarantees. Price, delivery and a measured 300 m²/30 m performance map remain unknown. Both diameters remain in this one practical mobile-family page.
