1. Product overview

YANOR HVLS ultra-large energy-saving industrial fan (model YN-HF7300M) is specially designed to provide integrated customized solutions for ventilation, cooling, dehumidification and dust removal for high spaces. It is widely suitable for steel structure factories, warehousing and logistics parks, large venues, animal husbandry and breeding bases, and high-rise open places such as supermarket exhibition halls.

Different from traditional small industrial fans, HVLS large fans rely on large-diameter wing-type blades to push massive amounts of air at low speeds, achieving global three-dimensional air circulation with extremely low energy consumption. While greatly saving electricity costs, they also improve the stifling, dampness, and dust accumulation in the workshop. and other issues create a comfortable and dry working environment.

2. Core product parameters (YN-HF 7300M)

Core advantages of triplex vector frequency converters

1. Adopting three-phase 380V vector drive technology, 180% high torque can be output under 0 Hz conditions, and the fan starts and stops smoothly without jitter;

2. Standard RS485 (Modbus) communication interface and centralized control cabinet can realize synchronous speed regulation and zone control of multiple fans;

3. Built-in multiple detection modules for current, vibration and speed, automatically alarm and shutdown when the equipment is abnormal, comprehensively protecting the motor and the whole machine.

4. Demonstration diagram of air circulation of large fan

1. Low energy consumption and large air volume core logic

When large-diameter airflow moves, the friction force is much smaller than that of small fans. After overcoming the initial inertia of the air, only a very small amount of power can be required to maintain a continuous flow of air over a large range. Coupled with YANOR's exclusive wing-type streamlined variable-section fan blades, wind resistance is minimized, electrical energy is efficiently converted into air kinetic energy, and "low power and large air volume" are truly achieved.

2. Global three-dimensional circulation airflow mechanism

The six fan blades are designed with an upturned 3-degree streamline. When slowly rotating, they push air downward to the ground in a cone shape. After the airflow touches the ground, it spreads around, forming a large-area horizontal airflow layer:

·The airflow can radiate to a maximum of 20 meters of the Youth Games center, covering a space 6 times its own diameter;

·Horizontal airflow hits walls and large equipment and flows back upward to the roof, forming a 360 ° three-dimensional air circulation without dead corners;

·Completely eliminate the temperature stratification above and below the factory building, and solve problems such as sultry top, wet ground, and stuffy smell of dust in corners.

3. Natural wind body cooling effect

The fan wind speed can be freely adjusted infinitely at 1 - 5 m/s. The circulating air flow simulates soft gusts in nature, accelerates the evaporation of sweat on the body surface, dredges skin heat dissipation pores, and achieves 5 - 8 ℃ body cooling. Continuously flowing air can also replace dirty indoor air, carry away moisture and suspended dust, effectively improve the high-temperature working environment, reduce the risk of heat stroke for workers, and improve overall work efficiency.

4. Multiple hard-core security protection technologies

The YANOR industrial large fan builds a full-link multi-layer safety protection structure to avoid the risks of fall and failure in all aspects from parts, installation structures to intelligent control systems. The product has gone through many years of testing under harsh working conditions, and has zero safety accidents throughout the process.

1. High-strength fastening system: All connecting fasteners are made of industrial high-strength bolts, and the actual bearing stress reaches more than 10 times the standard;

2. Double steel wire traction protection: A single traction wire can bear up to 1000 KG, and each hoisting point is equipped with double steel wire dual protection to eliminate the hidden danger of single cable rupture;

3. External safety protection ring for the whole machine: a special safety ring is equipped on the periphery of the fan to lock all moving parts when encountering impact from foreign objects to prevent the fan blades and motor from falling off;

4. Type I integrated fan blade chassis structure: 6 fan blades and the main engine chassis lock are an integrated structure, which is resistant to impact and shake, and the fan blades are not easy to break when emergency stop;

5. Intelligent frequency conversion fault warning: Monitor equipment vibration, current, and speed in real time. If there is any abnormality, the control system will automatically alarm and immediately stop the machine;

6. Structural safety commitment: Impact from foreign objects, emergency shutdown, and irregular start and stop operations will not cause fan components to fall; equipment will only be affected when the main body of the load-bearing building collapses.

The company has its own team of professional electrical, mechanical, and construction engineers, who can visit the factory building structure, complete load-bearing stress analysis, customize standardized safety hoisting plans, and follow strict installation specifications throughout the entire construction process.

5. Adapt to building and standard installation requirements

1. Adaptable to hoisting main beam type

H-shaped steel, I-shaped steel, steel-concrete square beams, spherical grid frames, and concrete load-bearing main beams can be installed in most factory building structures on the market.

2. Hard installation basic conditions

1. The indoor clear height of the factory must be greater than 4.5 meters;

2. The minimum safe distance between fan blades and obstacles such as walls, equipment, lights and other obstacles shall not be less than 0.3 meters;

3. There is no fixed production equipment or long-term fixed station for personnel vertically below the fan;

4. The power supply supports 220V single-phase and 380V three-phase industrial power supplies.

6. Full-cycle warranty and after-sales service

1. Official quality assurance standards

The whole machine has a 3-year warranty, and the supporting motor and triplex frequency converter simultaneously enjoy a 3-year free warranty; all products undergo full-process quality inspection and no-load trial operation before leaving the factory, and are produced in strict accordance with national and industry ventilation equipment standards.

2. Improve the after-sales response system

1. Speed online response: If the equipment fails during the warranty period, the customer service will follow up and handle it within 24 hours;

2. On-site maintenance services: For on-site failures, professional engineers will be arranged to visit within 48 hours. All parts and repairs within the warranty scope are free;

3. Safety responsibility guarantee: During the warranty period, if safety accidents occur due to product design, manufacturing and installation defects, the manufacturer shall bear all relevant responsibilities;

4. Lifelong maintenance support: After the warranty expires, continuous on-site maintenance and fault repair services are still provided, and only the cost of parts and basic labor service fees are charged.

VII. Standardized equipment maintenance guidelines

Standardized and regular maintenance can extend the service life of the fan and ensure long-term stable and safe operation.
