Can a Ventless Hood Mobile Cooking Station Be Used for Smelly Foods?
Yes, a ventless hood mobile cooking station can be used for smelly foods, but it reduces odors rather than completely eliminating them. Its real-world performance depends on the filtration technology, cooking method, menu intensity, and how consistently the system is maintained.

In any ventilation system, air removed by an exhaust fan must be replaced. If it is not, the room will develop negative pressure. This can reduce exhaust performance, make doors hard to open, cause drafts, and pull unfiltered air into the workspace.
The replacement air is called makeup air.

A ductless hood can reduce grease and odor from a commercial griddle, but it is not automatically suitable for every high-volume setup. Whether it works depends on the cooking method, smoke level, filtration design, local fire codes, and how well the unit is maintained.

The most common simplified method for calculating the required airflow (CMH) for a CNC oil mist collector is: Internal Enclosure Volume × Air Changes Per Minute × 60. Measure the effective internal volume (V) of the machining chamber (Length × Width × Height in m³), ​​deducting the volume of major internal components (approx. 10–20%).
Select the air change rate (N) (changes/minute): Light mist/low-pressure coolant: 4–5
Standard cutting fluid: 5–6 (most common)
High-pressure coolant/heavy mist/smoke: 8–10

Calculation:
CMH = V × N × 60

Example: Effective volume 5.25 m³, N=6 → 5.25 × 6 × 60 = 1890 CMH. Add a 20–50% margin (to account for filter clogging and ducting losses). Opening method (for poor sealing):
Opening area (m²) × Capture velocity (0.5–1.0 m/s) × 3600 = CMH. Empirical reference: Small enclosed machine tools: 500–1200 CMH
Standard machining centers: 800–1500 CMH
Large/heavy-duty machines: 1500–2500+ CMH

For actual model selection, it is recommended to provide the machine model, chamber dimensions, and coolant pressure to the manufacturer for confirmation, while also considering ducting resistance and filter pressure drop.
