Plenum starting points for 14 fan coil brands

Every manufacturer preset in our 3D plenum designer on one page: Ability Projects, Carrier, Daikin, Diffusion, FläktGroup, Fujitsu, Hitachi, LG, Midea, Mitsubishi Electric, Panasonic, Samsung, Toshiba and TROX. Each brand section lists our estimated supply and return connection sizes, the preset body, and a live price excluding VAT, with a link that opens the designer with that brand preselected.

Estimated, editable — not verified fits. Brand and model names identify units only. We are not affiliated with or approved by any manufacturer, and preset sizes are not taken from manufacturer data. Always confirm against your unit drawing.

Before you order — site checklist

1. Confirm the exact unit model and variant against the schedule and unit drawing.
2. Measure supply and return connection openings separately.
3. Check the connection type needed at the unit end.
4. Measure the clear ceiling void and choose flat top or flat bottom.
5. Mark grille or diffuser positions and spigot sizes.
6. Allow access space for filter sections, panels and hangers.

Pricing is based on body dimensions: £64.00 for 600×200, 400 deep, two Ø150 spigots (£68.69 with 6mm foam; £73.39 with 12mm); £110.00 unlined for 980×180, 400 deep, with four Ø150 spigots. Lining is charged by gross body surface area, with 12mm at twice the 6mm rate. Filter sections are confirmed by our team.
