1. Quick Answer: Which CHINENG Fume Solution Do You Need?

If the kitchen fails odor or oil-mist checks, or you are opening a new restaurant and must plan exhaust, do not buy a “bigger hood” alone. Match capture (hood), purification (electrostatic / oil-slinger / carbon), and airflow m³/h to the cookline length and cooking style.

Direct answer:

• Need capture only above the wok / range → frequency-converted range hood (from about $235.94)

• Need oil-mist cleaning before discharge (indoor / compliance focus) → integrated commercial cooking fume purifier — Indoor Direct Exhaust (CSP), Chain (STC), or Engineering (STPC)

• Need a stainless electrostatic package with listed oil-slinger discs → integrated fume purifier / electrostatic line (from about $2,008.33)

• Heavy chain / project sites wanting higher stated purification rate → Engineering STPC (catalog: 95%) or Chain STC (catalog: 90%); Indoor CSP highlights activated-carbon odor deep-clean claims on the product page

Prices on catalog pages exclude shipping, on-site service, and tax. Confirm live quotes and local exhaust rules before ordering.

2. Who These Systems Are Built For

CHINENG oil-fume equipment targets:

• Restaurants, Chinese kitchens, and chain outlets — see commercial kitchen solutions

• Hotel and catering kitchens with long cooklines

• Canteens and central kitchens that must control grease and odor

• Export buyers using the English site (plus Vietnam / Malaysia hubs)

You are in the right place if you want factory model ladders (hood → integrated purifier → electrostatic package) and clear airflow figures. Plan local electrical work, duct fabrication, and a cleaning schedule — grease modules and activated carbon are consumables / user-maintained items on the warranty notes.

3. Hood vs Purifier vs Integrated Unit

Rule of thumb: A hood without purification only moves grease farther down the duct. A purifier without enough capture still leaves smoke in the room. Most restaurant projects need both roles planned together.

4. Size by Airflow (m³/h), Not by Seat Count Alone

Undersized systems fail at wok peak, not at average covers. Use four steps:

1. Measure cookline length and cooking intensity (steam vs heavy frying / wok hei)

2. Target a purifier airflow class (e.g. 2500–5000 m³/h on CSP; 4000–6000 m³/h on CN-JD)

3. Match hood width (600–2000 mm classes on YDC) to the appliance run

4. Confirm 380V three-phase for most integrated purifiers; many hoods are 220V

Worked example: A 2.0 m Chinese cookline with heavy frying needs ~4000 m³/h class purification. On the integrated page, CN-8156-CSP-2.0 (4000 m³/h, 380V/1720W) or Chain CN-8156-STC-2.0 are the catalog matches — a 90D hood alone (24 m³/min ≈ 1440 m³/h capture rating) is not a full substitute for the purifier airflow row.

5. Integrated Commercial Cooking Fume Purifier Lines

Product page: Integrated Commercial Cooking Fume Purifier. Contact sales for unit pricing (starting price field may be empty on the English page).

5.1 Indoor Direct Exhaust (CSP)

Catalog notes for CSP: 1-year warranty; activated carbon for deep odor removal; cleaning/maintenance and carbon modules are user responsibility and excluded from warranty coverage as stated on the product page.

5.2 Chain Edition (STC) vs Engineering Edition (STPC)

Both editions list oil-slinger discs and electrostatic fields (plus high-voltage ionizer on selected rows). Choose STPC when the project brief asks for the higher catalog purification rate; choose STC for chain rollout with a lower profile height than CSP indoor units.

6. Stainless Electrostatic Precipitator (CN-RC-JD / CN-JD)

Product page: Integrated Fume Purifier — starting about $2,008.33.

Choose this line when: you want stainless electrostatic modules with explicit disc/field counts and 4000–6000 m³/h. Confirm whether the site needs the B-R dual-voltage listing or the CN-RC-JD 380V-focused codes.

7. Frequency-Converted Range Hoods

Product page: Frequency-Converted Range Hood — starting about $235.94. Most series use 220V and Ø200 mm exhaust duct.

Choose higher static pressure (≈1086 Pa VF series) when duct runs are long or have many bends. Dual-motor models roughly double exhaust rate for wider cooklines.

8. Power, Ducting, and Maintenance

• 380V is standard on CSP / STC / STPC integrated rows; electrostatic CN-JD often lists 380V with selected 220V options.

• Hoods are mostly 220V with Ø200 mm duct — plan make-up air so the kitchen is not starved.

• STC/STPC outlet size on catalog: 320 × 450 mm.

• Manual measurement tolerance noted on the integrated page: about 1–3 cm.

• Cleaning, corrosion from cleaning chemicals, and activated carbon modules are called out as user / consumable items outside the 1-year machine warranty on CSP.

9. Decision Tree — Buy This, Not That

• Only need capture above a short cookline → YDC hood (match width; pick VF if duct is hard)

• Indoor discharge / odor focus + carbon story → CSP Indoor Direct Exhaust

• Chain rollout, ~914 mm height, 90% catalog rate → STC

• Project brief needs 95% catalog rate → STPC

• Want stainless ESP with 3–5 discs and 4000–6000 m³/h → CN-JD / CN-RC-JD

• Long cookline + heavy frying → size purifier airflow first (4000–5000+ m³/h), then hood width

10. Application Examples

• Street-front Chinese restaurant (~1.6–1.8 m line): YDC-HZB or DX hood + CSP-1.6/1.8 or STC-1.6/1.8 for purification before discharge.

• Multi-unit chain: standardize STC-2.0 (4000 m³/h) so spare parts and cleaning SOPs match across stores.

• Hotel / banquet kitchen: STPC or CN-JD-200/240 for higher airflow and disc/field counts; pair with engineering VF hoods on long duct runs.

11. Frequently Asked Questions

11.1 Is a range hood the same as a fume scrubber?

No. A hood captures and moves air; a purifier / scrubber removes oil mist (and sometimes odor). CHINENG sells both under Oil Fume Purification.

11.2 How much does a commercial fume purifier cost?

Listed starting prices (machine only): about $235.94 for frequency-converted hoods and about $2,008.33 for the CN-RC-JD integrated fume purifier line. Integrated CSP/STC/STPC pricing is via customer support on the product page. Shipping, on-site service, and tax are extra.

11.3 What do the 90% / 95% / 99.8% figures mean?

They are manufacturer catalog claims on the integrated product page (Chain 90%, Engineering 95%, CSP activated-carbon indoor IAQ wording). Always verify against your local acceptance test method — do not treat catalog % as a substitute for site commissioning.

11.4 Do I need 380V?

Most integrated purifier rows are 380V. Many hoods are 220V. Some CN-JD models list 380V/220V — confirm the exact SKU with sales.

11.5 What is excluded from warranty?

CSP notes: 1-year on the unit; cleaning/maintenance damage and activated carbon modules are excluded as stated on the product page. Plan a grease-cleaning calendar regardless of model.
