If you are sourcing industrial vacuum equipment from China, you have probably come across InPowerVac. The brand is operated by Zhejiang Yingpa Electromechanical Co., Ltd, a manufacturer that entered the vacuum field in 2000 and launched its global brand strategy in 2019. Today the company runs production bases in Zhejiang and Hebei, operates 92 sets of processing equipment, and supplies customers such as Foxconn, Huawei, Samsung, and the Tata Group. So what are the main InPowerVac products? This guide walks through the seven product lines, explains what each one does, and shows where it fits best.
1. Rotary Vane Vacuum Pumps
The rotary vane vacuum pump range is the historical core of the InPowerVac catalog and comes in single-stage and two-stage versions. The oil sealed models cover a wide model lineup from V004 up to V1200, with an ultimate vacuum of ≤20 Pa and pumping speeds from 4 to 1,200 m³/h at 50 Hz. Imported bearings and oil seals, British oil mist filter technology, and an anti-backflow oil design give these pumps a long service life and low running costs. Specialty variants round out the line: explosion-proof pumps for hazardous areas, portable oil vacuum pumps for mobile service work, single-phase units for small workshops, pumps built for packaging machines, and vacuum aspirators for laboratories.
2. Roots Vacuum Pumps
InPowerVac roots vacuum pump models use a pair of figure-8 rotors that counter-rotate without contact, moving large gas volumes at high speed. Because a Roots pump cannot exhaust directly to atmosphere, it works as a booster in front of a backing pump, multiplying the pumping speed of the whole set. The range covers vacuum assist pumps, multi-stage Roots pumps, air-cooled and gas-circulation-cooled versions for thermal control, and big-pumping models for large chambers. Typical uses include metallurgy, freeze drying, vacuum coating, and any process that needs fast evacuation in the medium vacuum range.
3. Turbo Pumps
For high vacuum work, InPowerVac offers turbo vacuum pumps and complete turbo pump systems. These are oil-free pumps in the process chamber, and the top models reach pressures down to 10-7 mbar when backed by a suitable front stage pump. This product line serves applications such as semiconductor processes, surface coating, and analytical and laboratory instruments, where a clean, hydrocarbon-free vacuum is essential.
4. Dry Vacuum Pumps
Dry pumps are the largest InPowerVac category and reflect where the company has invested most heavily, including 32 Mazak machining centers dedicated to screw rotor production. The dry screw vacuum pump family uses two intermeshing rotors that compress gas with no oil in the chamber, so there is no risk of process contamination. Buyers can choose air-cooled versions noted for extremely low noise, water-cooled versions for tougher thermal duty, chemical-resistant builds, and even a TA10 titanium alloy oil-free screw pump for corrosive gases. Dedicated models serve lithium battery production, semiconductor manufacturing, pharmaceutical processing, and medical gas systems.
5. Oil Sealed Screw and Central Vacuum Solutions
Beyond classic vane pumps, the oil-sealed category covers centralized and intelligent vacuum supply. Central vacuum pumps use frequency-controlled speed adjustment to match output to demand and extend system life. The line also includes oil type screw energy-saving pumps, intelligent oil screw pumps with smart control features, high flow models for large-volume duties, and side channel blowers for combined vacuum and pressure tasks.
6. Vacuum Pump Systems
When a single pump is not enough, InPowerVac builds complete engineered systems. The catalog includes complex multi-pump units, vacuum pump booster systems, tank-mounted packages for compact installation, dry and oil vacuum systems, vacuum condensate return systems, and medical vacuum pump systems for healthcare facilities. The company also designs customized vacuum solutions for special fields, combining pumps, controls, and accessories into one ready-to-run unit.
7. Vacuum Components and Spare Parts
To keep equipment running, InPowerVac supplies the matching consumables: replacement vanes, vacuum pump oil, dust filters, oil filter systems, oil mist filters for exhaust recovery, and spare parts kits for rotary vane pumps. Long replacement cycles for consumables are part of the brand's low-maintenance, economical positioning.
InPowerVac Product Lines at a Glance
| Product Line | Key Feature | Typical Applications |
|---|---|---|

| Turbo Pumps | Oil-free, down to 10-7 mbar | Semiconductors, surface analysis |
| Dry Vacuum Pumps | Oil-free screw design; air- or water-cooled; titanium options | Lithium batteries, chemical and pharmaceutical plants |
| Oil Sealed Screw / Central Pumps | Frequency-controlled, energy-saving | Centralized factory vacuum supply |
| Vacuum Pump Systems | Engineered multi-pump units, customized builds | Medical facilities, special industrial processes |
| Components and Spare Parts | Vanes, oil, filters, oil mist filters | Maintenance and consumable replacement |
How to Choose Among InPowerVac Products
The right choice comes down to four practical questions:
- What vacuum level do you need? Rough vacuum duties such as packaging point to rotary vane pumps; medium vacuum with high throughput calls for a Roots booster combination; high vacuum work needs a turbo pump backed by a front stage pump.
- How harsh is the process gas? Corrosive or dusty gases favor dry screw pumps, with titanium alloy versions available for the most aggressive chemical duty.
- Is oil contamination acceptable? If not, choose from the dry pump or turbo ranges rather than an oil-sealed model.
- One machine or a whole plant? For centralized supply, an engineered vacuum system with frequency control usually beats multiple standalone pumps on energy cost.
Final Thoughts
The main InPowerVac products span seven lines: rotary vane pumps, Roots pumps, turbo pumps, dry vacuum pumps, oil-sealed screw and central pumps, engineered vacuum systems, and components with spare parts. Together they cover the spectrum from rough workshop vacuum to 10-7 mbar high vacuum, across industries from lithium batteries and semiconductors to packaging and medicine. If you are not sure which line matches your process, the InPowerVac engineering team can recommend a configuration or build a customized solution for your application.
