Product Features & Fitment

Constructed with durable aluminum blades attached to a rigid steel spider, the Lau 4C2033CW is engineered to resist corrosion and structural distortion in harsh outdoor environments. Its 33-degree blade pitch maximizes air volume across condenser coils for efficient heat rejection. Designed for use with an interchangeable hex hub (sold separately), this blade allows technicians to quickly match the required motor shaft diameter during field service.
