Why Has My Kitchen Chimney Lost Suction? (Baffle Filter Cleaning)

The Importance of Strong Suction

Indian cooking uses heavy oil, spices, and frying, which creates sticky grease smoke. A kitchen chimney relies on a high-velocity blower motor to pull this grease through filters and vent it out. When suction drops, grease starts settling on your kitchen cabinets.

Clogged Baffle Filters

Baffle filters work by forcing smoke to change direction rapidly, separating grease droplets from the air. Over weeks, this grease accumulates in the grooves. If not cleaned, it acts as a wall, blocking airflow and straining the motor.

Degraded Exhaust Blower & Motor

If grease gets past the filters due to poor maintenance, it sticks to the plastic or metal fan blades. This adds weight, unbalances the blower, and leads to high vibration, loud humming noises, and a drop in suction RPM.

Technician's Tip

While filters can be cleaned at home with caustic soda, a deep service requires dismantling the blower assembly and using specialized degreasers. Our chimney specialists restore factory suction in under an hour.
