This square wall exhaust fan adopts high toughness ABS plastic as the main housing material, paired with aerodynamically optimized multi-blade impellers to boost overall ventilation efficiency. The product lineup covers four complete specifications, with impeller diameters ranging from Φ150mm to Φ300mm and supporting matched standard square wall cut-out sizes for wall embedding installation only. Its core driving component is a DC variable frequency double ball bearing motor, built with comprehensive safety protection functions that effectively prevent motor burnout under abnormal operating conditions. Compared with traditional AC exhaust fans, the DC frequency conversion structure significantly reduces power consumption and suppresses operating noise during continuous use.

The fan provides a wide air volume range from 240m³/h to 1020m³/h, capable of handling ventilation tasks for small washrooms and large kitchens alike. The square compact body features a removable front cover, allowing users to disassemble the unit effortlessly to wipe away accumulated grease and dust on fan blades. All models are uniformly packed with ten units per carton with standardized carton dimensions, which greatly simplifies bulk transportation, storage and inventory management for wholesalers, project contractors and bulk purchasers.
