Technical SpecificationsAs the primary economic powerhouse of Moldova, Chisinau is experiencing a comprehensive industrial transition. The rise of designated economic areas, such as the Tracom Industrial Park and the subzones of the Free Economic Zone "Bălți" located in Chisinau, has catalyzed demand for advanced manufacturing equipment. Leading sectors, including wine bottling, food processing, pharmaceuticals, automotive component assembly, and construction materials production, now require state-of-the-art utility setups to stay competitive.
Within these sectors, rotary screw vacuum systems play a vital, often invisible role. In bottling lines, vacuum suction handles container transfer and de-aeration to preserve food and beverage quality. In the pharmaceutical and packaging sectors, maintaining clean, uninterrupted pressure vacuums determines the safety and shelf-life of final products. Adapting to fluctuating energy prices in Moldova requires localized industrial equipment to prioritize power efficiency. Shanghai Honest Compressor's variable speed drive (VSD) systems address this directly by matching motor speed dynamically to current system demand.
Our export models strictly follow EU directives adopted by Moldova, ensuring rapid customs clearance and compliance on the factory floor.
Engineered to operate reliably in summers exceeding 38°C, our thermal control systems prevent overheating and avoid unexpected downtime.
With electricity costs directly affecting overheads, our permanent magnet (PM) motors lower startup currents and improve part-load efficiency.
For industrial applications in Chisinau, selecting between rotary screw vacuum technologies and older liquid-ring or rotary-vane systems is critical. Standard liquid ring pumps are highly dependent on continuous water supplies, making them vulnerable to water hardness, corrosion, and municipal water costs. Our dry screw vacuum technology runs without process-side sealing oil or water inside the compression chamber. The non-contact, matching rotors ensure long service lives with minimal wear.
| Performance Parameters | Honest Dry Screw Vacuum Pumps | Traditional Liquid Ring Pumps | Rotary Vane Pumps |
|---|---|---|---|
| Process Purity | 100% Oil-Free & Water-Free chamber | Water dependent (risk of back-migration) | Oil sealing required (oil carryover risk) |
| Ultimate Vacuum Pressure | Down to 0.01 mbar (abs) | ~33 mbar (limited by water vapor pressure) | ~0.5 mbar (single stage) |
| Energy Consumption | Low (optimized by VSD PM Motor) | High (losses due to liquid shear) | Medium |
| Maintenance Interval | Up to 20,000 hours (Rotor Inspection) | Frequent (scale buildup & cavitation repair) | High (vane replacement every 3,000 hrs) |
Modern production facilities in Moldova benefit from dry-run rotary screw vacuum pumps by eliminating liquid disposal concerns and maintaining stable ultimate pressures. This stability is essential for automated packaging, thermoforming, and industrial drying, where minor pressure drops can impact product quality.
Every facility has unique requirements. We don't just ship machinery; we deliver complete vacuum and compressed air installations. Our packages include integrated control systems, filtration units, oil-water separators, and receiver vessels tailored to Chisinau's manufacturing standards.
Our technical sales team collaborates with local engineering firms in Chisinau to integrate PLC networks. This allows centralized SCADA platforms to monitor running conditions like temperature, motor speed, and oil levels, supporting predictive maintenance models that prevent unplanned stops.

Request QuoteFounded in 2004 as a British-owned enterprise, Shanghai Honest Compressor Co., Ltd. operates a manufacturing facility located at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China. We specialize in the large-scale production of twin-screw air compressors and advanced air system solutions.
Our product lineup features piston air compressors (low, medium, and high pressure; oil-free models), screw compressor systems from 3kW to 480kW, gas separation equipment, refrigerant compressors, cold dryers, ceramic membrane filtration units, and replacement consumables. We provide engineered solutions tailored to the needs of modern industrial operations worldwide, including Chisinau's manufacturing sectors.
We work to support clean, reliable production processes with energy-efficient equipment designed to reduce overall maintenance costs.
Industry reports estimate the global dry vacuum pump market size at US$ 5.97 billion in 2024. The market is projected to expand from US$ 6.17 billion in 2025 to US$ 8.28 billion by 2034, registering steady growth driven by the demand for clean, oil-free processing.
This growth reflects a broader shift across manufacturing sectors, where industries are replacing oil-sealed pumps with dry screw systems to minimize environmental impact and lower operational overhead. We showcase our latest VSD systems and dry screw designs at major regional trade exhibitions, supporting customers in upgrading their industrial utility setups.
Dry screw vacuum pumps run without oil in the compression chamber, meaning there are no oil filters, exhaust filters, or lubricating oil charges to replace regularly. While oil-sealed rotary vane pumps require oil changes every few thousand hours to prevent performance loss, dry screw pumps typically only need gear oil changes and bearing inspections at much longer intervals, reducing overall maintenance downtime.
Industrial electricity costs can be variable. Standard fixed-speed pumps run at full capacity regardless of actual demand, wasting energy during lower-load stages. VSD technology matches the motor speed to the real-time vacuum demand, helping to lower energy usage by up to 30-50% depending on the process cycle.
We handle export logistics directly from our Shanghai manufacturing hub. Shipments are typically routed through European ports like Constanța, Romania, and then transported by road to Chisinau. We supply all required export documentation, including CE declarations, certificates of origin, and technical files, to support clear customs processing in Moldova.
Yes, all export systems destined for Moldova and the wider EU are built with standard European electrical configurations (typically 380V/400V, 50Hz, 3-Phase). We use CE-certified electrical parts and components to ensure compatibility with local industrial grids.
We provide full technical documentation, detailed installation guides, and remote video commissioning support with our field engineers. For larger installations, we can coordinate with regional service partners in Eastern Europe to assist with startup, system optimization, and routine maintenance.
