Industrial exhaust fan, also known as negative pressure exhaust fan, discharges air outward to reduce indoor air pressure, make indoor air thinner, and form a negative pressure zone. The air will compensate for the pressure difference and enter the room, thus forming a canyon airflow belt with one in and one out. In practical applications, negative pressure fans are centrally installed on one side of the factory building. Through specific engineering design, the ventilation speed and wind speed are designed according to the needs, and any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop. Within a few seconds of turning on the fan, the negative pressure exhaust fan can be used to discharge the workshop. The doors and windows near the negative pressure fan should be kept closed, forcing air to flow into the workshop through the compensating doors and windows on the intake side. The air lined up and orderly flowed into the workshop through the air intake, forming a canyon airflow belt.



A、 Suitable for workshops with high temperatures or odors:Such as heat treatment plants, casting plants, plastic plants, aluminum profile plants, shoe factories, leather factories, electroplating plants, and various chemical plants.
B、 Suitable for labor-intensive enterprises:
Such as clothing factories, various assembly workshops, and internet cafes.
C、 Ventilation and cooling in horticultural greenhouses, as well as cooling in breeding and livestock farms.
D、 Especially suitable for places that require cooling and a certain level of humidity. Like tobacco warehouses, cotton mills, wool mills, linen mills, weaving mills, chemical fiber mills, warp knitting mills, knitting mills, etc.
E、 Suitable for the field of warehousing and logistics.




The Jiayou negative pressure fan series fan blades are made of 201 stainless steel material, which has the characteristics of high air volume, low noise, low energy consumption, long service life, stable operation, and beautiful appearance. It is easy to maintain and saves the trouble of changing belts! The automatic closing and opening of blinds can achieve dust-proof and waterproof effects, and can be used for blowing or drawing air. It is a good choice for cooling and ventilation in greenhouses and factories. Main structure:
The fan is mainly composed of fan blades, motors, frames, protective nets, support frames, louvers and other components. The motor drives the fan blades to generate airflow, and the movable louver type can be equipped according to user needs. After starting up, the louvers can automatically open, and when stopping, the louvers will automatically close to prevent outdoor dust, foreign objects, etc. from entering, as well as to avoid the influence of rain, snow and backflow.
Performance characteristics:
The outer frame adopts advanced automatic processing technology with a thick galvanized layer, which has strong corrosion resistance. Aluminum alloy die-casting wheel hub, new twisted stamping fan blade; A reasonable blade angle can achieve a large air flow rate; The microcomputer assisted manufacturing system can enable the fan to exert greater efficiency. 5 strict quality inspection procedures: noise detection, vibration detection, concentric rotation performance detection, fan blade speed detection, and overall efficiency detection; High performance 380V three proof dedicated motor. Adopting iron collectors, fiberglass collectors, and ABS engineering plastic collectors (three types) for easy disassembly; CAD optimization design.
