Fabricated Fan Boxes
Range: Cooling / Ventilation Enclosures – 200 mm to 600 mm Fan Modules, for Electronics Cabinets, Outdoor Panels, and HVAC Applications.
Our Fan Box is a powder-coated octagonal ceiling box built to carry the full weight of a ceiling fan. A 12 MM mounting rod
runs through the body and is welded to opposite walls, protruding on both sides to take the fan hook directly — no separate
rod or shackle needed. Multiple knockouts on the side and top walls allow flexible conduit pipe entry from any direction.
Features:
- Sheet metal enclosures fabricated from CRCA steel or 304/316 stainless, with powder-coated finish
- Designed to house axial or blower fan modules (standard sizes 200 mm / 300 mm / 400 mm / 600 mm)
- Includes louvers, rain-shields, vent grills, filters, and drip trays where needed
- CAD-based fabrication including CNC punching, bending, and spot welding for precision fit
- Vibration dampening mounts, gasketed doors, and thermal insulation layers
- Vent ports and internal baffling optimize airflow and provide dust ingress protection
- Fixed welded rod removes the need for a separate fan rod + shackle assembly; rated for standard ceiling fan loads.
- Confirm rod protrusion length suits your fan hook before ordering; match cut-out diameter to the ceiling opening.
