Centrifugal fan (belt driven)
Single-width single-inlet centrifugal fan for HVAC and process extract: hollow spiral scroll (you see the backward-curved wheel through the bellmouth and down the outlet) with flanged side sheets, inspection door, drain, rotation arrow and nameplate; shaft in two regreasable pillow-block bearings on a pedestal; V-belt drive under a mesh guard; IEC motor on slide rails; steel base frame on open spring isolators; optional flexible duct connectors with companion flanges. Outlet up-blast or top-horizontal; wheel diameter and kW scale the set. Ports are duct flanges (kind utility, NPS = equivalent round duct).
Installation
Copies rotating/centrifugal-fan.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.
Usage
import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { CentrifugalFan } from './components/deck-twin/rotating/centrifugal-fan'
export default function Scene() {
return (
<Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
<Stage>
<CentrifugalFan />
</Stage>
<OrbitControls makeDefault />
</Canvas>
)
}

P&ID
Circle (scroll) with a wide rectangular outlet duct leaving tangentially and curved blades or a hub drawn inside; inlet through the centre. Axial fans are drawn as a propeller (bow-tie) inside a circle or duct.
Looks like a pump but the outlet is a wide duct and it sits on HVAC ducting (often drawn double-line) rather than a pipe. Air cooler fans are part of air-cooled-exchanger.

For agents
Machine-readable entry with props, ranges, defaults and ports:
Or fetch /r/centrifugal-fan.json, or copy a ready-made instruction:
Add the Deck Twin "Centrifugal fan (belt driven)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add centrifugal-fan` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info centrifugal-fan` for its props, ranges and ports. Render <CentrifugalFan /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
