AirIQ Technology — the first kitchen chimney in the Mahajan Electronics range that tells you what's in your kitchen air
Standard kitchen chimneys perform a single function: extract air at a fixed speed when manually switched on. The user decides when to turn the chimney on, at what speed to run it, and when to turn it off — there is no feedback from the appliance about whether the kitchen air quality is actually improving, whether the current speed is sufficient, or whether the chimney can be slowed down to reduce noise because cooking intensity has dropped. AirIQ changes the paradigm from manual ventilation tool to active air quality management system. Particulate matter sensors in the chimney continuously sample kitchen air and calculate a real-time AQI (Air Quality Index) score — the same standardised measurement used by Delhi's air quality monitoring stations and the CPCB's Sameer App. This score is displayed on the chimney's panel in real time, giving the cook an objective reading of kitchen air quality rather than relying on visual smoke cues (which underestimate pollutant levels, as many combustion products from tadka and frying are invisible). AQ Sync then uses this continuous measurement to automatically modulate suction speed — accelerating during a heavy tadka or deep-fry session when AQI spikes, slowing during a simmer when less extraction is needed, and stopping automatically when air quality returns to baseline. For Delhi NCR households where ambient outdoor AQI is frequently 150–300 (Unhealthy) during October–February, kitchen cooking adds a further indoor AQI increment — AirIQ quantifies this addition and manages it actively rather than relying on manual estimation.
AQ Sync BLDC Motor — why brushless motor technology is the right choice for a chimney running 2–4 hours daily
A kitchen chimney in an active Indian household runs for 2–4 hours daily across multiple cooking sessions — that's 700–1,400 hours per year of continuous motor operation. Standard induction motors maintain constant speed regardless of cooking intensity, consuming the same energy at medium suction as at full suction because the motor always runs at full load with speed reduced via dampers that waste power. BLDC (Brushless DC) motors vary actual motor speed in response to the required suction level — at low suction (simmering, warming), the motor runs genuinely slowly and consumes significantly less power; only at peak suction (frying, tadka) does it draw maximum current. Over 700 hours of annual use, the energy saving of a variable-speed BLDC vs fixed-speed induction motor is meaningful. The absence of brushes also eliminates the primary mechanical wear mechanism — brushed motors' carbon brushes degrade and require replacement every 3–5 years; brushless motors have no such wear component, which is why Crompton can offer a 15-year motor warranty that would be commercially untenable on a brushed design.
Smart ON — the chimney that starts before the smoke reaches it
Standard chimney operation requires the cook to remember to turn it on before cooking begins — a step that is frequently missed or delayed, allowing the first burst of smoke and oil vapour from heating oil or initial tadka to enter the kitchen air before the chimney is activated. Smart ON uses thermal sensors that detect the temperature rise above the hob as cooking begins — the infrared heat signature of a gas burner or induction top activating is detected before any smoke is generated, and the chimney starts automatically at low suction. By the time the first tadka hits the oil, the chimney is already running and capturing the initial smoke burst at source rather than after it has dispersed into the kitchen. For households where the cook frequently handles multiple tasks at once (monitoring children, attending to other preparations, conversations), Smart ON removes chimney activation from the mental checklist entirely — the chimney becomes a background appliance that manages itself from first heat to air quality baseline without manual intervention.
Motion Sensor Gesture Control
Wave a hand within the sensor's detection zone to control the chimney — adjust speed, toggle power, or activate AutoClean without touching the panel. Hygienic and practical during cooking when hands are oily, wet, or covered in masala — no contact required to adjust settings. For open kitchen designs where the chimney panel is within reach of the cooking area, gesture control eliminates the "touch the panel with oily hands" problem that makes standard chimney controls unhygienic to use during active cooking.
Intelligent AutoClean
Internal heating element activates during AutoClean cycle to liquefy accumulated oil deposits in the baffle/mesh filters, draining them into the built-in oil collector. Standard chimney maintenance requires removing filters, soaking in hot water + detergent, scrubbing, and reinstalling — a 20–30 minute task that most households defer until filters are heavily clogged, reducing suction efficiency. AutoClean reduces this to pressing a button — the chimney cleans itself and the oil collector is emptied periodically. For households where chimney cleaning is the most avoided appliance maintenance task, AutoClean converts a 30-minute chore into a 30-second intervention.
1800 m³/hr — Indian Cooking Rated
1800 m³/hr suction is appropriate for a 75cm chimney serving 3–5 burner hobs with heavy Indian cooking. The standard formula for chimney sizing is kitchen volume (m³) × 10–15 air changes per hour = required suction; a 3×3×3m kitchen requires 270–405 m³/hr minimum — 1800 m³/hr provides 4–7× this minimum, ensuring effective extraction even during simultaneous multi-burner heavy cooking with frying, tadka, and grilling running together.
Midnight Black Toughened Glass
Toughened safety glass in Midnight Black — resistant to thermal shock from the heat cycles of daily cooking, chip-resistant edges, and fingerprint-showing reduced compared to polished black. Midnight Black's dark matte-adjacent finish reads as a premium design choice against both white and dark modular kitchen cabinetry, providing the visual anchoring of a statement appliance without the maintenance burden of mirror-polished surfaces.
Free Installation + Ducting Kit
Installation by Crompton's authorised team is included — chimney wall mounting, duct routing, and connection to existing or new external ventilation. The ducting kit covers standard installations; non-standard installations (long duct runs, concealed ducting through walls, ceiling routing) may require additional components. For buyers upgrading from an older chimney, the installation team handles removal of the existing unit. Getting chimney installation right — correct duct diameter, minimum bends, appropriate external terminal — determines the actual suction the chimney delivers vs its rated capacity; professional installation ensures the rated 1800 m³/hr is achieved in practice.
47 dB — Kitchen Conversation Friendly
47 dB is quieter than normal conversation (60 dB) and similar to a quiet library (45–50 dB) — the AQNova can run at medium suction during dinner preparation without requiring raised voices in an open kitchen, making it suitable for kitchen-dining spaces where conversation continues while cooking. The BLDC motor's lack of brush friction and the AQ Sync's speed modulation (running at genuinely lower RPM during lighter cooking) both contribute to the low noise floor.
