Portable Screw Air Compressors are widely used in various industries for mines, water conservation and supplies, shipbuilding, city development, energy development, military services, and others.
Kaishan's Electric Screw Air Compressors (LG portable series) has a power range from 11 kW to 250 kW, as well as a displacement covering up to 40 m3/min. Each basic model can transform into a series of products with different displacement and discharge pressure based on customers' requirements.
Screw Air Compressors feature the following main advantages:
1. High reliability: These air compressors have less components and parts, none of which are prone to wear and tear. Thus, it offers reliable operation with a long service life. The overhaul gap may reach 40,000 to 80,000 hours.
2. Easy operation and maintenance: It is highly automated. Operators are not required to receive extensive professional training. It can operate on its own without the presence of technicians.
3. Good dynamic balance: It can steadily operate at high speeds without any unbalanced inertial force. It can operate without any designated space, which is particularly suitable for small, lightweight, and portable air compressors that require little spatial occupation.
4. Strong adaptability: With forced air injection, its flow capacity is almost free from discharge pressure, and maintains its high efficiency within a large rotational speed range.
