6074 BLDC BLACK 90cm Specifications, Features & Compatibility Guide

The auto-clean system works by running the motor at maximum speed while activating a thermal cycle in the filter chamber. The heat causes solidified grease to liquefy and drain by gravity into a removable collection cup. This engineering approach prevents the motor from bearing additional load from a grease-clogged filter — a root cause of premature motor failure in chimneys without this feature. Thermal protection in the motor circuit prevents the motor winding from overheating during extended high-speed operation — a common occurrence in Indian households during festival cooking marathons. The protection triggers a temporary shutoff rather than an irreversible failure, resuming operation once the motor cools.
