Oil-Sealed Rotary Screw Vacuum Pumps » Entagear Co., Ltd.
Atlas Copco’s oil-sealed rotary screw vacuum pumps bring reliable, efficient rough vacuum to the general industry. The GHS 1200-4800 combines a robust oil-sealed rotary screw technology with Atlas Copco’s advanced screw element design.
Providing up to 4778 m3/h of vacuum pumping performance across six models, the GHS series is ideal for critical applications in printing, electronics, plastics, packaging, woodworking, bottling, canning and similar exacting industries.
The GHS 1200-4800 combine a technologically advanced screw design with robust and highly regarded oil-sealed rotary technology to produce a state-of-the-art, market-leading product.
In the GHS 1200-4800 range of vacuum pumps, industry-leading screw technology meets many years of vacuum know-how. Add a conservative approach to machine speed and you have all the benefits of Atlas Copco’s screw element, including inherent reliability, optimal efficiency and life cycle costs.
GHS rotary screw vacuum pumps outperform many other vacuum technologies in their operating pressure range. They are available ready to use, with all the options you need, and supported by the best know-how.
• Ensuring that GHS 1200-4800 vacuum pumps are quiet – from 82 dB(A) – so they can be located alongside your machine in areas where people work.
• Guaranteeing high reliability and extreme durability.
Eliminating the need for swing-out doors, saving valuable space.
• Optimizing performance when cycling from atmospheric pressure to the operating vacuum level.
• Preventing internal and efficiency sapping back-pressures during operation close to atmospheric pressure. The result is fast response to process changes.
• Enhancing the appearance of the vacuum pump.
• Allowing delivered performance to be matched to actual demand.
• Minimizing fluctuations in system vacuum level.
• Reducing wear and maintenance, as a result of fewer stops/starts.
• Preventing condensed water vapor from contaminating the oil reservoir, even in demanding conditions.
• Consistent and continuous performance during humid duties with minimal impact on component lifetime within the oil circuit.
GHS 1200-4800 vacuum pumps are durable, highly reliable and fitted with generously rated motors making them last a lifetime.
• Easily replaceable cartridge type elements sized to minimize back-pressure and optimizing the delivered performance.
• Ensuring long operating life with a minimum number of service interventions.
• Allowing operation close to atmospheric pressure, without the consequences often found when excessive optimization takes place.
Our new innovative and intelligent vacuum pump – the GHS VSD+ range of screw vacuum pumps with capacities up to 1900 m³/h – representing a real leap forward in the vacuum industry.
• Quiet operation – Noise levels are around half that of comparable technologies.
• Sustainable productivity due to built-in efficiency. Conforms to energy management and environmental commitments according to ISO 50001/14001.
• Reduced environmental impact due to ultra-high oil retention at all operating pressures – from ultimate pressure to atmospheric pressure.
