Before you understand the difference between a ventilation fan and an exhaust fan , you must first understand the concept between a ventilation fan and an exhaust fan. So what is a ventilation fan? Ventilating fan A type of air conditioning appliance that is driven by a motor to rotate the air flow of a fan blade to allow indoor and outdoor air exchange. Also known as the ventilation fan. The purpose of ventilation is to remove the dirty air in the room and regulate the temperature, humidity and sensory effects. What is an exhaust fan? Exhaust fan, driven by the motor to rotate the air flow fan blade, so that indoor and outdoor air exchange a class of air conditioning appliances. Also known as the ventilation fan. The purpose of the exhaust is to remove the dirty air in the room and adjust the temperature, humidity and sensory effects. After reading the above introduction, next, we will come to understand the difference between ventilation fans and exhaust fans and other related knowledge.
Ventilation fan specifications
Specification one:
Some bathroom exhaust fans are a closed type. Their function is different from that of the first exhaust fan, but there is a certain difference in appearance. This type of exhaust fan is generally a 30.5cm*30.5cm square design and is more stylish.

2, the kitchen can use 250 mm shield ventilation fan, if the kitchen has been equipped with exhaust hood, ventilation fan can not be installed.
3, bedroom and living room area is generally about 12-16 square meters, with a 250-300 mm two-way ventilation fan is more appropriate.
When choosing, pay attention to the following points:
1. The ventilator fan has a novel appearance, the color is coordinated with the color of the room, the plane has no warping phenomenon, the plastic parts are smooth and smooth, the electroplating parts are bright, there are no traces of rust marks, and the fan blades can rotate.
2. After the power is turned on, the blade rotates smoothly, without abnormal noise, and the air volume is large. Self-bleaching shutters are flexible and flexible. Linked shutters turn sensitively on all sides. Bi-directional ventilation fans convert freely. The temperature of the motor is not too high and the noise is low. With the speed control function of the ventilation fan speed obviously, capacitive motor is not more than 65%, cover plate type is not more than 80%.
Ventilation fan installation method
Before the ventilation fan is installed
1. Before installing the ventilation fan, you should carefully check whether the machine is intact, whether the fastener bolts are loose or fall, whether the impeller bumps, and whether the blades or louvers are damaged during transportation is carefully checked.
2. When selecting the air outlet environment, it should be noted that the air outlet can not have too many obstacles within 2.5-3M.
Ventilation fan installation
1. Installation is stable: When the ventilation fan is installed, attention should be paid to the horizontal orientation of the fan, and the fan should be adjusted to the same level as the foundation plane. After the ventilation fan is installed, there can be no skewed appearance.
2. When installing the ventilation fan, make the adjustment bolts of the motor easy to operate. In order to use, adjust the ventilation fan belt elasticity.
3. When installing the ventilation fan bracket, make sure that the bracket is horizontally aligned with the ground plane, and if necessary, reinforce the angle iron next to the ventilation fan.
4. After installing the fan, check its surrounding tightness. If there is free space, it can be sealed with a sun plate or glass glue.
Exhaust fan installed
1. After the installation is completed, check if there are any leftover objects and debris inside the ventilation fan. Move the fan blade with your hand or lever to see if there is overtightness or scratches on the surface, and there is no abnormality in the items that hinder the transformation. Can do trial work.
2. If abnormal ventilation or other anomalous appearances of the ventilation fan appear when the fan is oscillating or if the motor has “嗡嗡†or other anomalous appearances, it shall be stopped for inspection.
Ventilation fan installation precautions
1. Ventilation fan must be firm and strong when installed, and it is 2.3m above ground.
2. The interval between the ventilation fan and the roof must reach 5CM or more;
3. The ceiling ventilation fan should not be installed in places with many fumes and dust, and should be installed near the high temperature source.
4. The wall type of the fan can be ventilated and ventilated at all locations and can also be used for oil smoke;
Difference between ventilation fan and exhaust fan

Guide sleeve is a mold accessory which is used together with guide pillar to play a guiding role.
Mold Components, used together with guide pillars, play a guiding role. Generally, the fit clearance is very small, within 0.05mm; generally, they are mostly used in molds or some machines to ensure the accuracy of movement.
Die Guide sleeve, also known as die guide sleeve, high-strength brass bearing, is on the base of high-strength brass. A high performance solid lubricant product embedded with graphite or MoS2 Solid lubricant. It breaks through the limitation that the general bearing relies on oil film lubrication. In the process of using, the solid lubrication and the shaft are rubbed by the friction heat, forming the excellent condition of oil and powder coexisting lubrication, which not only protects the shaft from wear, but also makes the solid lubrication characteristic eternal. Its hardness is twice as high as the common copper sleeve, and its wear resistance is also twice as high.
shape
There are five basic shapes of solid inlaid bearings: straight sleeve, flange sleeve, sliding block, thrust gasket and bearing bush. In case of good hardness, high wear resistance, no oil supply, high load and low speed, it can give full play to superior performance, superior drug resistance, corrosion resistance, flexible design, simple, convenient and rich standard products, which can be used with standard axis.
application
It is widely used in high temperature, high load, low speed and heavy load occasions such as metallurgical caster, train support, steel rolling equipment, mining machinery, ships, steam turbines, etc.
