Anest Iwata Scroll Pumps

Anest Iwata Scroll Pumps for Clean, Oil-Free Vacuum

Anest Iwata is a leading global manufacturer of vacuum pumps, compressors, and related equipment. With a history spanning over 90 years, the company has extensive experience in the industry and is recognized for its high-quality products and exceptional customer service. Anest Iwata's products are used across pharmaceuticals, electronics, automotive manufacturing, and many other industries, with each solution built around the unique needs of the application.

Anest Iwata was the first in the world to develop air-cooled, oil-free, scroll-type vacuum pumps. The ISP series that resulted from that innovation remains one of the cleanest, quietest ways to generate roughing and backing vacuum, and Provac stocks new and rebuilt units across the full range, along with the pump modules and parts that keep them running.

Why Choose Anest Iwata Scroll Pumps?

Anest Iwata's oil-free scroll vacuum pumps are compact and emit less noise and vibration than other dry vacuum pumps, which is why they are highly valued by customers who need clean, high-quality vacuum, especially in analytical and semiconductor-related fields. The ISP series eliminates the nuisance of lubricant maintenance or sealing water administration entirely.

• Oil-free, air-cooled scroll technology
• Compact design with low noise and low vibration
• No water utility required for cooling
• Low power consumption from atmosphere to maximum vacuum
• No gears, so no gear oil to exchange and no risk of leaked lubricant
• Minimal routine maintenance, with no oil changes, filters, or foreline traps to replace

Because the ISP series runs completely dry, it is free from many of the installation restrictions that come with oil-sealed or water-cooled vacuum technology, making it a flexible choice for labs and production floors alike.

The ISP Scroll Pump Range

Anest Iwata builds the ISP line in a range of sizes so you can match pumping speed to your chamber and your process. The lineup runs from the compact ISP-50 through the ISP-90, ISP-250, and ISP-500, up to the high-capacity ISP-1000, giving facilities a scroll pump sized for everything from a single benchtop instrument to larger industrial roughing and backing duty.

How a Scroll Pump Works

An Anest Iwata scroll pump uses a unique scroll impeller design, with one fixed scroll and one orbiting scroll working together. As the orbiting scroll moves, it creates a continuous process of suction, compression, and exhaust with little change in torque, which is what gives these pumps their characteristically low vibration and quiet operation. Because there is no oil or sealing water in the gas path, the pump stays clean over its entire service life, and the only meaningful wear item is the scroll tip seal.

Anest Iwata Scroll Pumps FAQ

1. What makes Anest Iwata scroll pumps different from other dry pumps?

Anest Iwata was the first in the world to develop air-cooled, oil-free, scroll-type vacuum pumps. Their unique scroll impeller design creates a continuous process of suction, compression, and exhaust with little change in torque, resulting in lower noise and vibration than other comparable dry vacuum pumps.

2. Do Anest Iwata scroll pumps require a water utility?

No. The ISP series is fully air-cooled, so it is free from the installation restrictions that come with water-cooled vacuum technology and does not require sealing water administration.

3. What sizes are available in the ISP range?

The ISP line runs from the compact ISP-50 through the ISP-90, ISP-250, and ISP-500, up to the high-capacity ISP-1000, allowing you to match pumping speed to your chamber size and throughput.

4. What industries commonly use Anest Iwata scroll pumps?

These pumps are widely used in pharmaceuticals for distillation, drying, and evaporation, in electronics for semiconductor manufacturing and vacuum deposition, and in food and beverage processing for freeze-drying and vacuum packaging, along with chemical processing, aerospace, and medical applications.

5. How much maintenance does an ISP scroll pump need?

Very little. Because the pump has no gears and no oil in the gas path, there are no oil changes, filters, or foreline traps to replace, and routine maintenance mainly comes down to periodic scroll tip seal service.
