High-Efficiency China OEM 8~10 Bar Oilless Food and Medical Grade 100% Oil-Free Silent PM VSD Rotary Single Screw Air Compressors

Product Description

The China OEM 8~10 Bar Oilless Food and Medical Grade 100% Oil-Free Silent PM VSD Rotary Single Screw Air Compressor is designed for excellence in both food and medical applications. This innovative air compressor stands out due to its advanced features and dependable performance.

2~40bar Direct-Drive Water-Injected Oil-Free Screw Air Compressor (PM VSD)

1. Low Temperature for Enhanced Efficiency

Operating at an exceptionally low running temperature of less than 60ºC, the compressor achieves near isothermal compression. The superior cooling capability of water effectively removes heat, delivering more air per kW of power, thereby eliminating the need for an internal cooler and aftercooler, and reducing pressure drop to a minimum.

2. Cost-Effective Maintenance

Spare parts required are limited to air filter elements and water filter elements. The low operating temperature ensures the long service life of the screw air end, avoiding expensive maintenance costs for the screw rotor and reducing stress on other components.

3. Energy Efficiency to Avoid Pressure Drop Costs

Despite being non-apparent at the purchase time, the costs associated with combating pressure drops are significantly high and contribute to the total cost of ownership. This compressor mitigates such costs efficiently.

4. No Gearbox Required

Eliminating the need for a gearbox also negates the necessity for associated oil lubrication, simplifying maintenance and operation.

5. Simplified Structure

With fewer moving parts compared to a dry oil-free screw air compressor, there is less that can go wrong. The balanced bearing loads extend the compression element service life, ensuring low-cost operation.

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.
