China Manufacturer Air Cooling Elgi Twin/Double Oilless Screw Air Compressor Low Pressure

Product Description


Under varying conditions, gas demand can fluctuate significantly. Extensive research and market analysis confirm that only about 10% of applications require a consistent air supply. Therefore, frequency conversion compressors can play a pivotal role in energy conservation.

Energy costs often constitute 70% of a compressor’s life cycle expenses. The production of compressed air may account for 40% of a plant’s total electricity costs. In nearly every factory, gas consumption varies across different time periods, with peaks and troughs. The permanent magnet variable frequency screw air compressor can adapt to these changes, providing air according to consumption requirements. This not only saves energy but also contributes to environmental preservation for future generations.

Performance Characteristics of Oilless Air Compressors

Oilless air compressors are designed to operate without the need for oil lubrication, which distinguishes them from traditional air compressors. Here are the key performance characteristics:

Oil-Free Operation

An oilless air compressor does not require oil for lubrication, which reduces the risk of oil contamination in the compressed air. This feature is particularly beneficial in industries such as food and beverage, pharmaceuticals, and electronics manufacturing where clean air is crucial.

Low Maintenance

Without the need for oil changes and related maintenance, oilless air compressors offer lower maintenance costs and simpler upkeep. This leads to less downtime and more reliable operation.

Environmental Friendliness

Oilless air compressors produce fewer emissions and are more environmentally friendly due to the absence of oil disposal issues. This makes them a sustainable choice for various applications.

Quiet Operation

These compressors typically operate more quietly than their oil-lubricated counterparts, making them suitable for environments where noise reduction is important.

Enhanced Durability

Oilless air compressors often feature advanced materials and design that enhance their durability and longevity, providing long-term reliability.

Types and Characteristics of Oilless Air Compressors

Oilless air compressors come in various types, each with unique characteristics and suitable applications.

Reciprocating Oilless Air Compressors

These compressors use a piston driven by a crankshaft to deliver air at high pressure. They are known for their compact size and efficiency in delivering high-pressure air.

Rotary Screw Oilless Air Compressors

These compressors use twin screws to compress air, offering continuous operation and reduced noise levels. They are ideal for industrial applications requiring a steady supply of compressed air.

Scroll Oilless Air Compressors

Scroll compressors use two spiral-shaped scrolls to compress air. They are appreciated for their quiet operation, reliability, and low maintenance requirements.
