Why Air Motors Work Well in Sterilized Environments

Air motors are efficient and safe. They can dynamically load torque to match the needs of an application. It is unlike the fixed torque of an electric motor. They work well in high temperatures, humidity, and corrosive or flammable environments. They also work well in sterilized environments. The fundamental idea is that compressed air containing stored energy enters the sealed motor chamber and applies pressure to the rotor’s vanes.

They are Safe

Air motors can work well in hazardous environments because they don’t use electricity and don’t produce sparks. They are also self-cooling and can withstand high ambient temperatures. In addition, they don’t require special housing and cost less than an explosion-proof electric motor. Additionally, air motors can operate in a wide range of positions and rotate in both directions. They can be controlled easily by regulating the air supply’s flow and pressure without expensive electronic speed controls. They can also be stalled without harm and don’t lose power like electric motors when they are reversing quickly. However, electrical motors have more precise speed control and can be linked to sensors, programmed, and even alert operators when preventive maintenance is due. They can also be operated from a conditioned compressed air system, making them more energy efficient than an air motor operating directly from the plant air source. It makes them more suitable for applications that require a higher level of control and precision.

They are Versatile

Air motors can be used in many industrial applications, such as mixing liquid substances, moving materials, powering conveyor belts, machine tools, and bottling machines. They are also suitable for harsh and hazardous environments because they do not generate sparks. In addition, they can operate in wet and corrosive environments. Some of them even come with ATEX certification to allow them to work in explosive environments. Most Gast air motors comply with ATEX 100a and EC Directive 94/9EC standards. They have fast response times, allowing them to adjust their speed instantly and accurately.

Moreover, they consume less energy than electric motors due to their constant displacement design. Utilizing the proper regulator is crucial since the air supply to the air motor determines its speed in inverse proportion to that quantity. Limiting the rated motor inlet pressure to around 2/3 of its maximum line air pressure is a general rule of thumb. It will prevent it from starting too quickly and stalling.

They are Easy to Maintain

Air motors can be used in various industrial applications, including raising foundry copes and drag, mixing mixers, and cranes. They are also an excellent choice for sanding, grinding, and other abrasive activities in environments that might be hazardous to electric motors. One of the main advantages of air motors is their ease of maintenance. They are instantly reversible without sparking, create no heat buildup, and have a broad torque and speed range. Moreover, they can save energy by running only when activated.

Additionally, they can be easily controlled by using simple flow control valves. Their performance depends on the dynamic air pressure measured at their air inlet, and by regulating the air pressure and flow, you can get proportional torque and speed variation. This way, they can run only when necessary and consume about three times less energy than an electric motor. They also have low noise levels and are suitable for sterilized environments.

They are Efficient

Air motors use compressed air to set a rotor in motion within an eccentric cylinder. As the rotor spins, its vanes press against the cylinder wall, transforming pressure into rotational energy. The motors are very efficient and require minimal maintenance. They produce a constant torque at a fixed speed, even when the air supply flow and pressure vary. The speed can be controlled by regulating the air supply pressure and flow. The motors do not need expensive electronic speed controls, which can cost several times more than an air motor. They are excellent for portable applications because of their high power-to-weight ratio. They are also safe in hazardous environments since they do not generate electrical sparks and can operate safely in areas with explosive gases or vapors. They are often available in explosion-proof or ATEX versions. Unlike electric motors, they are also suitable for wet or corrosive working conditions. They can support continuous start and stop cycles without damage and run cool at all speeds.
