Industrial mobile fans are high-power ventilation and cooling equipment designed for industrial scenarios such as factories, workshops, warehouses, and construction sites. Their core features revolve around the high load, large space, multi working conditions, and easy mobility requirements of industrial scenarios. Unlike household fans, which have lightweight and low-power characteristics, their core advantages are concentrated in four dimensions: power performance, structural durability, mobility flexibility, and safety protection. The specific core features are as follows:
1、 High power and high air volume, suitable for ventilation and cooling in large spaces
This is the core performance characteristic of industrial mobile fans, designed specifically for open spaces such as factories and workshops, to meet the needs of large-scale air circulation and cooling:
High power motor and high air volume: Equipped with pure copper core industrial grade motor, the power is usually between 0.5~2.2kW (household fans are generally only 0.05~0.15kW), the air volume can reach 18000~80000m ³/h, and the coverage radius can reach 20~30 meters. A single fan can meet the ventilation needs of hundreds of square meters of space.
Wide range speed regulation and high wind pressure: supports 3-5 speed regulation, and some high-end models are equipped with variable frequency speed regulation function, which can accurately adjust the air volume according to the needs of the scene; The wind pressure is much higher than that of household fans, which can penetrate the dust and hot air layer in the workshop, achieving forced convection of air instead of simply blowing on the surface.
Large diameter fan blade design: The fan blade diameter is mostly industrial grade specifications such as 750mm, 1000mm, 1250mm, 1400mm, etc. It adopts streamlined biomimetic design (such as three leaf/five leaf curved blade shape) to ensure high air volume while reducing wind resistance and operating noise.
2、 High strength structural design, durable and adaptable to harsh working conditions
Industrial scenes often encounter problems such as dust, vibration, and collisions, so the structural durability of fans is key. The overall design follows the principle of "heavy-duty, anti loss":
Thickened metal body: The frame, base, and protective cover of the body are made of cold-rolled steel plates or galvanized steel plates, with a thickness of 1.2-2.0mm. The surface is treated with spray rust prevention, which can resist dust, water vapor corrosion, and slight mechanical collisions in the workshop. The service life can reach 5-8 years (usually 1-3 years for household fans).
Stable heavy-duty base: The base is made of reinforced cast iron or thick steel plate welded structure, with a weight of up to 20-50kg. Some models are equipped with water tank/sand box counterweight design, which can ensure the stability of the body and prevent tipping even when the fan is running at full load or strong wind is pushing back; The connection between the base and the bracket is reinforced with bolts, which have strong vibration resistance.
Wear resistant transmission and bearings: using high-precision ball bearings (instead of oil containing bearings for household fans), wear-resistant, high temperature resistant, suitable for 24-hour uninterrupted operation; The connection between the fan blades and the motor is reinforced with a coupling to avoid transmission looseness caused by long-term high-speed rotation.
3、 Highly flexible design, adapted to the mobility and adjustment needs of industrial scenarios
In industrial production, the demand for ventilation and cooling will change with the production process and material stacking location, so "easy to move and adjust" is an important feature:
Convenient mobile structure: The base is equipped with heavy-duty universal wheels (diameter 8-12cm), two of which have brake functions. Even if the fan weighs over 100kg, 1-2 people can easily push it; The wheel axle adopts a sealed bearing design to prevent dust and iron filings from entering and causing jamming.
Multi dimensional angle adjustment:
Up and down adjustment: The fan head can achieve 0~90 ° pitch adjustment, which can blow air separately for ground operation areas and high-altitude equipment areas;
Left and right rotation: The connection between the bracket and the base adopts a 360 ° rotation structure, and the fan head can rotate horizontally by 180 °~360 °, covering no dead corners;
Height adjustment: Some large industrial fans are equipped with extendable brackets, which can be adjusted in height between 1.5 and 3.0 meters to meet the ventilation needs of different heights (such as cooling high-level equipment in the workshop and cooling in the ground personnel operation area).
Split/Folding Design: Some models adopt a bracket and base split structure for easy transportation and storage; Small industrial fans are designed as foldable brackets, which can be folded and stored when idle, saving space.
4、 Comprehensive safety protection, in compliance with industrial safety regulations
The industrial scene has strict requirements for equipment safety, and the safety protection design of industrial mobile fans is much higher than that of household fans. The core meets the norms of workshop safety production:
Encryption type safety protection cover: The protective cover is welded with thickened steel wire (diameter 4-6mm), with a mesh spacing of ≤ 50mm (the mesh spacing of household fans is usually ≥ 80mm), which can effectively prevent the operator's fingers, clothing, as well as debris and tools in the workshop from being rolled into the fan blades, avoiding safety accidents.
Motor overload and leakage protection: Built in overload protector, when the motor is overloaded due to unstable voltage, foreign object jamming or other reasons, it will automatically cut off power protection to prevent the motor from burning out; Simultaneously equipped with leakage protection plugs or grounding terminals, in accordance with the grounding safety regulations for industrial electricity, to avoid the risk of leakage and electric shock.
Anti dumping and anti vibration protection: Some high-end models are equipped with a dumping power-off switch. When the fan tilts more than 15 degrees due to collision or external force, the power will be automatically cut off and the operation will stop; The motor casing is wrapped with shock-absorbing rubber pads to reduce vibration transmission during operation and lower noise.
High temperature resistant and explosion-proof design (special models): For high-temperature workshops (such as forging and casting workshops) and flammable and explosive workshops (such as painting workshops and chemical workshops), there are dedicated high temperature resistant and explosion-proof industrial fans, using high temperature resistant insulation materials, explosion-proof motors, and sealing structures to meet the safety requirements of special working conditions.
5、 Low noise operation, taking into account the comfort of the production environment
Despite its high power and air volume, industrial mobile fans achieve low-noise operation through structural optimization, avoiding interference with production operations: the operating noise is usually controlled at 65-85dB (1 meter away from the fan), far below the environmental noise standards of industrial scenes. Some variable frequency models can reduce the noise to below 60dB when operating at low gears.
