EN Series Lubricated Screw Air Compressor 4-20 hp

WHY ELGi EN Series Screw Air Compressor?

Best-in-Class Reliability
ELGi’s EN Series 4-20 hp rotary screw air compressors are designed to encapsulate all functional components and the compressor within one common housing. With their small footprint, high reliability, and low maintenance requirements, the EN Series compressors are ideal for small and medium-scale industries such as food packaging, sorting, garages, machining, and fabrication workshops.

Compact & Elegant Design
The EN Series air compressor is compact and offers a space-saving design powered by ELGi’s energy-efficient η-V profile, with reduced risk of leaks due to integrated components and connections.

Energy-efficient
ELGi’s EN Series screw air compressors come with our unique, compact, and silent assembly that offers energy-efficient operations with minimal pressure drops across the system.

Best-in-class Maintenance & Operation Cost
The EN Series has a slow-running airend with fewer parts and connections than any other compressor in its class, which ensures minimal maintenance.

Efficient Air-Oil Separation
The air-oil separation in the EN Series air compressor is achieved through the impact and deceleration. In the circumferential tank area, the impact of the air-oil mixture prompts deceleration action to remove the oil particles from the compressed air. The air with minor traces of oil then enters the separator for further purification.

Optional Variable Speed Drive for Energy Efficiency
ELGi offers a variable speed drive option for the EN Series EN07-EN15 models. Variable Speed Drives help air compressors match the compressed air output with demand by varying the motor’s speed. When the demand goes down, the power consumption also goes down, eliminating the frequent load-unload cycle and saving energy over time.

Indigenously Designed Neuron Control System Offering Operational Data & Safety Measures
The EN Series screw air compressors are equipped with a custom-engineered Neuron XT controller. They come with several features, like malfunction alarms, safety shutdowns, and easy-to-use service indications, allowing you to monitor and control the machine's overall performance.

Low Noise Levels
ELGi’s EN Series screw compressors are known for their low noise levels. At 65 dBA the EN Series offers the lowest sound level in the industry, making them perfect in conditions where noise levels can affect the working conditions of your staff.

CAR WASH

A 4 hp air compressor is a simple and reliable compressed air solution that ensures you receive reliable and quality compressed air with low maintenance costs. Its low noise levels make the EN Series air compressors ideal for car washes with compressor rooms adjacent to customer service areas.

WOOD WORKING

ELGi’s rotary screw compressors offer efficiency in the woodworking process by enabling continuous operations with maximum productivity and profitability, making them suitable for the demands of medium to large furniture manufacturing operations. With robust design and energy-efficient operation, a 20 hp screw compressor ensures reliable compressed air supply for medium to large-scale operations.

TEXTILES

Industrial rotary screw compressors are used for various purposes in the textile industry. Powering looms, textile spinning machines, and machinery for handling fabric are all made possible by compressed air. ELGi’s EN Series 4 hp-20 hp rotary screw air compressors support textiles and apparel manufacturing by enabling precise control over operations.

AUTOMOTIVE SHOPS

EN Series rotary screw compressors can be found powering tools across many automotive shops across North America. The EN Series is compact and quiet making it perfect for car shops. The ELGi EN Series compressor is best suited for car shops that require consistent compressed air flow throughout the day.

MACHINING AND FABRICATION WORKSHOPS

With a compact design and low noise levels, ELGi’s EN Series screw-type compressors are well suited for small workshops and fabrication units to ensure constant and efficient compressed air supply. They are energy efficient and are low maintenance. Their flexible sizes allow for a balanced compressed air supply for diverse applications, enhancing the process. With advanced cooling and encapsulated design, the 20 hp screw compressor guarantees reliable output even in challenging environments.

How do EN Series compressors work?

The ELGi EN Series compressors work systematically to produce compressed air for a range of industrial applications. An intake filter ensures that contaminants are eliminated before the air enters the system, starting with the intake of atmospheric air. The air is cleared of dust and other contaminants after going through a filtering stage, which is essential for avoiding internal component damage. The compressor's heart is located in the compression chamber, where male and female rotors of interlocking helical screws rotate. The air is drawn into the profiles of these screws as they rotate, gradually compressing the air inside. Some designs inject oil into the compression chamber to seal screw gaps, improve compression and dissipate heat.

After compression, the compressed air is cooled to retain efficiency, and any remaining oil is removed using an oil separation mechanism. The pressure of the compressed air is carefully controlled by sensors and control systems, and it is kept in a receiver tank to buffer variations in demand. In the end, pipelines distribute the compressed air for numerous industrial applications.

FAQ'S

What maintenance is required for an oil-lubricated rotary screw air compressor?

Keeping your air compressor on a regular service schedule is key to having it perform optimally and extend its lifespan. Regular maintenance includes changing the compressor oil, replacing oil filters, checking and tightening belts, inspecting air and oil coolers, and cleaning or replacing air filters. Refer to the ELGi product manual for a detailed maintenance guide.

When should one consider upgrading from a reciprocating compressor to a small screw air compressor?

If your application demands a constant flow of compressed air at a consistent pressure level, a small screw air compressor might be the ideal choice. 4 hp to 4.5 hp air compressors are known for their efficiency in handling large volumes of compressed air. Additionally, if your focus is on energy efficiency, reduced maintenance downtime, and a compact design, upgrading to a screw compressor becomes a viable option. Screw compressors excel in maintaining a stable airflow and are generally more compact and quieter, making them suitable for applications with space constraints. The decision to upgrade to a 4 hp air compressor should align with your specific application needs. Our compressed air experts are available to help you make an informed choice tailored to your requirements.

What are the advantages of using an oil-lubricated rotary screw compressor?

Oil-lubricated rotary screw compressors offer superior cooling and sealing, ensuring efficient operation and longer lifespan. Rotary screw compressors are excellent for high-demand industrial applications, delivering consistent and reliable compressed air.

How noisy are oil-lubricated rotary screw compressors compared to piston compressors?

Oil-lubricated rotary screw compressors operate at much lower noise levels than reciprocating compressors. Their smooth rotary motion and enclosed design make them suitable for indoor installations where reduced noise is a priority.

Why should I choose a 20 hp screw compressor instead of a piston compressor?

A 20 hp screw compressor is more energy-efficient, operates with lower noise, and is designed for continuous duty applications, unlike piston compressors that are better for intermittent use. A 20 hp rotary screw air compressor is widely used in textiles, automotive, packaging, and general manufacturing industries where continuous, large-volume compressed air supply is required.

Are oil-lubricated rotary screw compressors suitable for continuous 24/7 operation?

Yes. Oil-lubricated rotary screw compressors are specifically designed for continuous duty applications. Their efficient cooling system and lubrication design allow them to run reliably around the clock, making them ideal for industries such as manufacturing, metal fabrication, and oil & gas where uninterrupted compressed air is essential.
