Engineered for maximum reliability, lower operational costs, and absolute energy efficiency under rigorous continuous operations.
As one of the most industrialized nations in the European Union, the Czech Republic’s economic engine thrives on advanced machinery, automotive manufacturing (Mladá Boleslav and Kolín clusters), metallurgical processing in Ostrava, and world-renowned precision glassmaking in Northern Bohemia. Under the pressure of volatile European energy markets and the strict mandates of the EU EcoDesign Directive, Czech industrial operators are aggressively phasing out inefficient, legacy liquid ring and rotary vane vacuum setups.
Modern screw vacuum pumps represent the pinnacle of this efficiency paradigm. By integrating Permanent Magnet (PM) synchronous motors and Variable Frequency Drive (VFD) controls, our solutions directly match pump displacement speeds to real-time industrial demand. This transition eliminates system pressure spikes, protects tooling interfaces, and slashes electrical consumption by up to 35% compared to fixed-speed vacuum equipment.
Whether it is managing thermoforming processes in plastic manufacturing, driving pneumatic transport loops in food processing, or securing continuous degassing cycles in high-precision glass melt furnaces, our twin-screw and rotary vacuum systems deliver the reliable performance profiles needed to maintain high-yield production runs across Bohemia and Moravia.
British-owned legacy combined with advanced engineering scale to power industrial operations worldwide.
Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise. It was founded in early 2004. Our manufacturing plant is strategically located at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China. We are a large-scale manufacturing enterprise specializing in the production of twin-screw air compressors in China. At the same time, we are also an important supplier of air system solutions globally.
Our comprehensive production matrix includes piston air compressors (low pressure, medium pressure, high pressure, oil-free designs), screw air compressor systems ranging from 3kW to 480kW, gas separation equipment, refrigerant compressors, cold dryers, specialized filters, ceramic membrane filtration systems, and all corresponding equipment accessories and consumables.
We fully implement strict management protocols throughout the entire manufacturing process, keeping a meticulous eye on product quality, environmental protection compliance, and thermal efficiency. Our production lines are certified in complete accordance with the ISO9001:2015 Quality Management System. Our focus remains deeply rooted in tracking technical developments to match modern, dynamic market demands.
By absorbing the operational advantages of leading international brand structures and integrating our own design principles of simplified maintenance access, the vacuum systems and compressors we produce demonstrate superior energy-saving statistics. Tested and verified by the National Compressor Inspection Center, our energy consumption data consistently outperforms global benchmark standards. We provide complete site layout design and consulting, comprehensive user training, and complete maintenance hosting programs, backed by our dedicated customer service channels.
Unlocking thermodynamic and mechanical advantages for high-performance applications.
The variable-pitch rotor design provides internal compression within the screw channels, lowering discharge temperatures. This approach achieves a compression profile that runs closer to isothermal conditions, decreasing power draw and increasing volumetric performance.
Featuring IE4/IE5 ultra-high efficiency permanent magnet motors, our VFD controllers respond dynamically to system pressure changes. By adjusting motor rotation speed, the system keeps the operating vacuum constant without the power losses linked to traditional throttling valves.
For chemical and pharmaceutical operations where contamination is a risk, our dry screw pumps feature intermeshing rotors that run without contact. Free of process-chamber lubricants, they eliminate the risk of oil backstreaming and reduce downstream disposal requirements.
Individual pumps perform best when integrated into a properly balanced, centralized network. Shanghai Honest Compressor Co., Ltd. designs and supplies integrated vacuum stations engineered to manage fluid, pressure, and gas flow rates across complex industrial setups. By networking multiple twin-screw and rotary pumps, our configurations handle variable system demands while keeping backup capacity in place.
Every setup shipped to the European Union market conforms to modern electrical, mechanical, and safety standards, and is configured to run under local plant control networks. This helps maintain stable pressure controls for processes that cannot tolerate vacuum fluctuations, such as glass handling, automated pick-and-place lines, and chemical separation processes.
Ensuring seamless import, compliance safety, and long-term service support for Czech customers.
Every vacuum system and screw compressor sent to the Czech Republic is built in compliance with EU Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility Directive 2014/30/EU, carrying the official CE marking.
Our permanent magnet synchronous motor technology meets the strict efficiency standards of European Commission Regulation (EU) 2019/1781, helping local companies qualify for regional environmental and energy grants.
Via our corporate hotlines and local distributor networks in European business centers, we support operators with engineering guidance, troubleshooting, fast parts delivery, and diagnostic checkups.
Explore our complete range of twin-screw compressors, oil-free vacuum lines, and permanent magnet air systems.
As factories transition toward Industry 4.0 models, vacuum systems must evolve beyond simple mechanical setups to become smart, interconnected nodes in an automated system. At Shanghai Honest Compressor Co., Ltd., our engineering roadmap focuses on integrating advanced industrial IoT capabilities directly into our vacuum and compressor controls. This integration allows our equipment to continuously monitor parameters like rotor temperature, vibration profiles, and discharge pressures, enabling predictive maintenance schedules before operational issues occur.
Furthermore, we continue to refine our twin-screw rotor profiles. By using high-precision machining centers and updated surface coatings, we keep volumetric leakage paths minimal, even under high pressure differentials. These steps ensure our equipment continues to meet the requirements of energy-sensitive markets like the EU, helping operators lower energy use and reduce carbon output.
Expert answers to common engineering questions regarding the application and operation of screw vacuum pumps in Central Europe.
Dry screw pumps do not require water as a sealing medium, eliminating wastewater disposal costs and water consumption. They provide high, stable volumetric performance across their operating range and are immune to fluid cavitation issues caused by hot water.
Because the twin-screw rotors run without contact, wear in the process chamber is minimal. Maintenance is primarily focused on changing gear lubricants and replacing inlet filter elements, which keeps overall maintenance costs low.
Yes. Our systems can be configured with intake separator liquid traps and gas ballast valves to safely handle condensable vapors, preventing internal condensation and protecting the pump chambers.
Our standard PLC systems support Modbus TCP/IP, Profibus, and CANopen protocols, allowing integration into DCS and SCADA networks for monitoring and system control.
