Kashiyama NeoDry 100E Oil-Free Dry Vacuum Pump

Overview

The Kashiyama NeoDry 100E is an oil-free, dry rotary vane vacuum pump engineered for high-reliability operation in demanding laboratory and pilot-scale industrial applications. Unlike traditional oil-lubricated pumps, the NeoDry 100E employs a precision-machined, non-contact rotary vane architecture—where vanes float within the stator chamber without mechanical contact against each other or the housing wall. This eliminates wear-induced degradation, enabling stable vacuum performance over extended service life and eliminating oil contamination risks critical in ultra-clean processes such as lithium-ion battery electrode drying, vacuum deposition, and analytical instrumentation interfacing. Its air-cooled thermal management system removes dependency on external cooling water, reducing footprint, installation complexity, and potential leakage hazards. Designed and manufactured in Japan under stringent quality control standards, the NeoDry 100E delivers consistent ultimate vacuum down to 2 Pa (without gas ballast) and achieves a maximum pumping speed of 1670 L/min at atmospheric inlet pressure—making it suitable both as a primary vacuum source and as a robust forepump for high-vacuum systems including turbomolecular and cryogenic pumps.

Key Features

• Oil-free dry operation ensures zero hydrocarbon backstreaming—essential for contamination-sensitive processes in semiconductor fabrication, battery R&D, and surface science.
• Non-contact rotary vane design eliminates friction-based wear, supporting maintenance intervals up to three years under ISO Class 5 (cleanroom-grade) ambient conditions.
• Integrated gas ballast valve (optional) enables continuous removal of condensable vapors—including water vapor—up to 600 g/h, significantly extending pump life during vacuum drying and solvent degassing cycles.
• Variable-frequency drive (VFD)-compatible motor delivers precise speed control, low acoustic emission (≤58 dB[A]), and minimal mechanical vibration (≤8 μm p-p), ensuring compatibility with vibration-sensitive instruments such as electron microscopes and mass spectrometers.
• Compact air-cooled construction (576 × 320 × 365 mm; 93 kg) simplifies integration into benchtop enclosures, gloveboxes, and automated vacuum workstations without requiring dedicated coolant infrastructure.
• Robust 3-phase motor (1.1 kW, 200–240 V AC, 50/60 Hz) provides stable torque across operational load ranges and complies with IEC 60034 efficiency standards.

Sample Compatibility & Compliance

The NeoDry 100E is compatible with a broad spectrum of sample types and process environments where hydrocarbon-free vacuum is mandatory. It is routinely deployed in vacuum ovens for moisture removal from cathode/anode slurries, in vacuum chambers for physical vapor deposition (PVD) and chemical vapor deposition (CVD), and as a forepump for high-vacuum analytical tools including scanning electron microscopes (SEM), transmission electron microscopes (TEM), and residual gas analyzers (RGA). The pump meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Its design supports compliance with Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) frameworks when integrated into validated systems—particularly where audit trails for vacuum parameter logging (e.g., via optional analog/digital I/O interfaces) are required per FDA 21 CFR Part 11 guidelines.

Software & Data Management

While the NeoDry 100E operates as a standalone unit, its electrical interface supports integration into centralized vacuum system controllers via standard 0–10 V analog input/output and RS-485 Modbus RTU communication. When paired with Kashiyama’s optional NeoControl monitoring module, users gain real-time access to operational parameters—including actual pumping speed estimation, motor current draw, temperature trends at critical bearing locations, and cumulative runtime hours. All logged data can be exported in CSV format for traceability and long-term trend analysis. The system architecture allows synchronization with LabVantage, Thermo Fisher SampleManager, or custom LIMS platforms—facilitating alignment with ISO/IEC 17025 accreditation requirements for calibration and preventive maintenance scheduling.

Applications

• Vacuum drying of hygroscopic materials (e.g., LiCoO₂, NMC cathodes, polymer electrolytes)
• Deaeration of resins, adhesives, and composite precursors prior to casting or molding
• Evaporation and distillation under reduced pressure in organic synthesis labs
• Primary vacuum generation for freeze-dryers (lyophilizers) and rotary evaporators
• Forepumping for turbomolecular pumps in surface analysis systems (XPS, AES, SIMS)
• Vacuum packaging of oxygen- and moisture-sensitive pharmaceutical intermediates
• Gas purging and inert atmosphere establishment in glovebox transfer lines
• Vacuum-assisted resin transfer molding (VARTM) in aerospace composites manufacturing

FAQ

Is the NeoDry 100E suitable as a forepump for turbomolecular pumps?

Yes—the NeoDry 100E’s ultimate vacuum of 2 Pa (without gas ballast) and high pumping speed make it well-suited as a forepump for turbomolecular pumps with inlet conductances ≥200 L/s.
Can it handle solvents like acetone or ethanol during vacuum distillation?

Only when the optional gas ballast is engaged and operated within the specified 600 g/h water-equivalent vapor load limit; aggressive organic vapors may require additional cold traps or scrubbers.
Does the pump require periodic oil changes?

No—this is an oil-free dry pump; no lubricating oil is used in the compression chamber.
What is the expected service life under continuous operation?

With proper inlet filtration and operation in particulate-free environments, mean time between failures (MTBF) exceeds 25,000 hours; scheduled maintenance is recommended every 36 months or 12,000 operating hours, whichever occurs first.
Is the motor compatible with variable frequency drives (VFDs)?

Yes—the 3-phase induction motor is VFD-rated and supports speed modulation between 30–100% of nominal RPM for energy optimization and process tuning.
