- True Balanced Airflow: This single compact ceiling unit extracts stale, humid air and supplies filtered fresh air at the exact same time. It is India's first true balanced ventilation unit built specifically for the Indian bathrooms, wardrobes, and small rooms.
- Advanced Twin Motors: The system utilizes two independent DC EC centrifugal motors. These supply and extract speeds are perfectly matched to ensure your room never experiences negative pressure.
- Streamlined Installation: It completely replaces the need for two separate fans. This design requires only one ceiling cutout and uses four neatly paired ducts, eliminating competition for ceiling space.
- Smart Control & Filtration: Both motors are easily operated from a single control point, using either a 3-speed wall panel or a mobile app. Incoming air is kept clean thanks to a built-in, washable G4 pre-filter.
- Discreet & Durable: The unit is flush-mounted and silent, designed to completely disappear into your ceiling. It is built with a matte black galvanized steel body, features IP44 ingress protection for wet areas, and comes with a 1-year standard warranty.

India’s First Balanced Bathroom Ventilation Unit: Breathes Out, Breathes In Together
In the modern era of airtight construction with fixed aluminium and double-glazed windows, traditional exhaust fans only do half the job. When doors are closed, exhaust fans choke for lack of make-up air. When doors are open, they pull expensive conditioned air from your bedroom, sending electricity bills soaring. The Dwell BALANCE Series changes the equation: powered by twin synchronized DC centrifugal motors inside a single concealed ceiling cassette, it exhausts stale, humid air while simultaneously delivering purified, filtered outdoor fresh air—restoring perfect pressure equilibrium to your bathroom.
The Modern Window Dilemma
- The Choked Fan Phenomenon: With fixed aluminium windows and closed bathroom doors, exhaust fans pull against a vacuum, reducing air movement to near zero while doors stick shut.
- The Air Conditioning Penalty: If the door is left open for make-up air, the exhaust fan greedily sucks chilled air from your bedroom, overloading your air conditioner.
- Odor & Humidity Migration: Unbalanced pressure causes moisture and odors to whistle through gaps into adjoining walk-in wardrobes and hallways.
The Dwell BALANCE Solution
- Breathes Both Ways Simultaneously: Motor 1 pulls humid steam out while Motor 2 delivers filtered outdoor fresh air in, keeping room pressure perfectly balanced.
- Zero AC Load Penalty: Make-up air is sourced entirely from outside through dedicated ducting—your bedroom climate and air conditioning remain untouched.
- Purified Inflow: Outdoor air is stripped of dust, pollen, and PM2.5 particulates via a washable G4 pre-filter and high-efficiency HEPA filtration core.
Twin Synchronized DC Centrifugal Motors
Built with two dedicated, energy-efficient DC motors inside a single casing. Factory-tuned with an exhaust-led ratio (e.g. 230 m³/h extract vs. 180 m³/h supply on Balance 100), it maintains a slight controlled negative offset that prevents odors from escaping while ensuring smooth, continuous airflow.
Dual-Stage G4 Pre-Filter + HEPA Purification
Never pump raw outdoor pollution into your home. Incoming fresh air passes through a washable G4 coarse dust pre-filter and an integrated HEPA filter, trapping atmospheric dust, soot, and allergens before delivering purified air into your bathroom.
Sleek Wireless Touch Controller
Complete control without trenching bathroom marble. The included wireless digital controller features a sleek capacitive interface displaying real-time ambient temperature, WiFi connectivity, Smart automation, and 3-speed manual control.
Ultra-Slim Matte Black Ceiling Cassette
Engineered to disappear completely above the false ceiling. With casing heights as slim as 123 mm (Balance 100), it fits easily into shallow ceiling voids, replacing two separate machines, dual wiring, and cluttered ceiling cutouts with a single unified unit.
True Balanced Pressure Engineering
When a room cannot breathe in as fast as it breathes out, standard exhaust fans struggle against vacuum resistance. Dwell BALANCE synchronizes supply and exhaust volumes dynamically, eliminating door-sticking, gap-whistling, and unconditioned air backdrafts entirely.

How the 4-Duct Balanced Flow Operates
Dwell BALANCE integrates two independent centrifugal fan paths within an acoustically insulated galvanized steel chassis, connected to four dedicated duct collars.
Outdoor Fresh Intake
Draws clean, oxygen-rich outdoor air through an external weather louvre into the primary filter chamber.
Dual-Stage Purification
Incoming air passes through a washable G4 pre-filter and HEPA core, discharging purified fresh air into the room.
Targeted Stale Extraction
The exhaust blower pulls steam and stale air directly from high-humidity zones (shower cubicle and WC).
Exterior Discharge
Pressurized humid air is expelled outside through an independent exhaust duct with zero room backdraft.
