Core Benefits of Air Compressors
Energy Efficiency
Energy is converted between different forms. With air compressors, large internal engines take electrical energy as an input and convert it to kinetic energy. Energy efficiency is highly related to engine size/horsepower, air pressure capability, and storage tank capacity.
A compressor’s design and operational efficiency affect how much electrical energy is required to reach a certain pressure level (PSI). Not all equipment requires the same pressure level, so having flexibility can save money. Newer compressors, such as variable speed drive (VSD) compressors, adjust speeds up or down as needed – further improving possible efficiencies.
Versatility and Portability
Many industrial tools plug directly into a compressed air source – air sprayers in a car repair workshop and pneumatic air tools come to mind. Without compressed air, they will not operate.
Industrial-sized modern air compressors use smart unit controllers. These allow precise operations to minimise total operating costs while maximising efficiency. Greater versatility is made possible, allowing for a smaller equipment footprint. Halting air operations for maintenance without suffering serious downtime is easier to achieve.
By correctly choosing the size of the air compressor and related equipment, smaller and more portable air compressors are possible. Talk with our team at J LL Leach to explore what size of air compressor you need.
Safety and Reliability
Electrically powered equipment, generating internal kinetic energy, is prone to malfunction and potentially causing electric shocks. Air-powered tools operate differently, dramatically enhancing operator safety. This applies even when operated at a higher temperature or raised torque.
Air-based tools are functionally more reliable. Fewer malfunctions and reduced downtime result in smoother operations. Compressor maintenance is still necessary, however, the improved design minimises it.
Operational Efficiency
Newer air compressors include remote monitoring features using SmartLink software solutions or similar. Which permits control from an office location or remotely using a secure internet link.
For operations managers, precise software control of air compressor technology reduces service interruptions. Air production is more manageable to balance near-term needs versus production costs to meet specific air volume and pressure level requirements.
Noise Reduction
Noise reduction is necessary to prevent potential operator hearing loss. The latest air compressors use various sound reduction technologies to reduce emitted decibels to safe levels. This includes canopies, the use of sound-absorbing materials, and well-made parts.
Sound dampening, smoother internal operations, and pairing usage and pressure levels to air generation requirements, do the rest.
Choosing the Right Air Compressor
Technological improvements have expanded the range of air compressors. Choosing the most applicable compressor for clean air is now possible based on operational needs, demand for compressed air, and energy efficiency.
Types of Compressors
Piston Compressors – Piston compressors are the smallest and most portable. They rely on a simpler system using pistons to produce compressed air. For example, tyre specialists wheel them out, attach the air hose to the customer’s air valve, and re-inflate a low-pressure tyre. The trade-offs are that they are relatively noisy, are less energy efficient, and are less suited to industrial environments.
Rotary Screw Compressors – Rotary compressors range from 2kw to 300kw in size and can be floor or tank mounted. They are sometimes portable, depending on their size but more often stationary. They use multiple rotary screws compressing air between them, instead of using a piston. This is a more energy efficient way of producing compressed air .
Variable Speed Drive Compressors – The latest VSD compressors are more energy efficient matching the load of the compressor with the end user’s demand and can also be integrated with remote control systems for improved control and flexibility and remotely monitored to support for intermittent operations, and the ability to adjust speed based on demand.
