Global commercial kitchen operators are facing a 25-40% increase in energy overheads. High-efficiency upblast fans with PMSM technology are no longer a luxury but a strategic necessity for ROI.
From NFPA 96 in the USA to ErP directives in Europe, the demand for certified, fire-safe, and grease-extracting fans is reaching an all-time high in 2024-2025.
As cities become denser, roof-mounted upblast fans must manage noise pollution and odor dispersion more effectively, leading to innovations in variable speed control and sound dampening.
Established in March 2018, Suzhou Liangzhi has emerged as a premier manufacturer of PMSM motors and HVLS fans. Our independently developed permanent magnet motors and controllers represent over 6 years of industry-leading innovation.
Our company vision is to provide reliable and affordable HVLS fans for every large space, ensuring safety and thermal comfort through advanced engineering.

Upblast fans discharge air vertically away from the roof surface. This prevents grease from accumulating on the roof, which is a major fire hazard and can damage roofing materials.
Permanent Magnet Synchronous Motors (PMSM) offer higher efficiency (up to 95%), less heat generation, and better variable speed control compared to traditional AC induction motors.
For high-volume cooking, fans should be inspected and cleaned monthly. Low-volume operations may require quarterly maintenance to ensure fire safety compliance.
Yes, our heavy-duty series are designed for both kitchen grease and industrial smoke, provided the static pressure requirements match the facility design.
