Dry Screw Vacuum Pumps | IDS 850 and 1100
Oil-Free Vacuum for Demanding Applications
The Elmo Rietschle IDS Series is a dry screw vacuum pump built for process-critical applications where cleanliness, uptime, and operating cost matter most. Available in two models, the IDS 850 and IDS 1100, it delivers up to 1,030 m³/h (606 CFM) and an ultimate vacuum down to 0.003 mbar (abs), with no oil in the pumping chamber.
Aircom Technologies, an authorized Elmo Rietschle distributor based in Kirkland since 1999, provides sales, service, and genuine parts across Eastern Canada.
Why a Valve-Free Design Matters
In real industrial processes, gases don’t stay clean. Vapors can condense or form solids, deposits build up inside valve mechanisms, and traditional unloading valves can become unreliable. The IDS removes this risk with a valve-free compression design that keeps operation stable, even with vapor-laden or dusty process gases.
Key Features
- Oil-free dry screw technology: no oil contamination in the process environment
- Deep ultimate vacuum: down to 0.003 mbar (abs) on the IDS 1100
- High pumping speed across a wide operating range, thanks to precision-machined screw geometry
- Variable speed drive (VSD) on the IDS 1100: matches pump speed to demand, reducing energy consumption by up to 50%
- Up to 40% lower total cost of ownership: fewer wearing parts, fewer service interventions, and lower energy use
- Valve-free compression and anti-condensation design for dust and vapor tolerance
- Low internal temperatures: optimized screw pitch and an advanced water-cooling circuit support continuous duty
- High mechanical stability: shaft support bearings on both ends
- Multi-stage shaft seals protect components from aggressive or contaminated gases, with optional gas pressurization and purging
- Water-cooled motor as standard, air-cooled available on request

IDS: Frequently Asked Questions
What is the difference between the IDS 850 and the IDS 1100?
The IDS 850 runs at fixed speed, with 810 m³/h and an ultimate vacuum of 0.03 mbar (abs). The IDS 1100 has a variable speed drive and reaches 1,030 m³/h and 0.003 mbar (abs). It is available with an 18.5 or 22 kW motor; the 22 kW is recommended for better performance in rough vacuum.
What is the difference between the IDS and the SVT?
The IDS is a dry, oil-free pump designed for deep process vacuum. The SVT is an oil-lubricated screw pump with variable speed drive, optimized for energy-efficient centralized vacuum between 100 and 250 mbar (abs).
Can the IDS handle vapors and dust?
Yes. Its valve-free compression and anti-condensation design avoid the deposits that build up in traditional unloading valves. Multi-stage shaft seals protect the components, and gas pressurization and purging are available as options for aggressive gases.
Is the IDS water-cooled or air-cooled?
The standard configuration uses a water-cooled motor. An air-cooled motor is available on request for both models.
Does Aircom provide service and genuine parts for IDS pumps?
Yes. Aircom supplies genuine Elmo Rietschle parts and offers preventive maintenance, troubleshooting, and repairs for industrial vacuum systems throughout Eastern Canada.
