Vacuum Generation & Power Solutions

Q: How do I choose between a dry scroll pump and an oil‑sealed rotary vane pump for my lab?

The choice depends on your required ultimate pressure, gas composition, and tolerance for oil vapor. Dry scroll pumps reach 0.02–0.05 mbar and are 100% oil‑free — ideal for analytical instruments (mass specs, SEM) and cleanroom environments where hydrocarbon back‑streaming cannot be tolerated. Oil‑sealed two‑stage rotary vane pumps achieve 10⁻³ mbar or better, but they emit oil mist (even with exhaust filters) and require regular oil changes. For general chemistry applications like rotary evaporation or vacuum ovens, an oil‑sealed pump is cost‑effective. For UHV systems, a turbo pump backed by a dry scroll is preferred. We can advise based on your specific process.

Q: What is the typical service interval for a roots pump booster system?

Roots pumps (dry running) typically require bearing and gear inspection every 15,000–20,000 operating hours, or every 2–3 years. The backing pump (rotary vane or dry screw) has its own maintenance schedule — oil changes every 2,000–4,000 hours for oil‑sealed, and bearing replacement every 10,000–15,000 hours for dry screw. Our control system tracks runtime and alerts you when service is due. We also offer preventive maintenance contracts with on‑site or exchange service.

Q: Can I use a dry pump for aggressive gases like chlorine or silane?

Standard dry scroll pumps use aluminum housings and PTFE tip seals, which are resistant to many solvents but not to halogens or silanes. For aggressive chemistries, we offer specialized pumps with nickel‑plated rotors, stainless steel gas paths, and purge ports to dilute reactive gases. For example, our corrosion‑resistant dry screw pumps (model DRY‑CR) are rated for continuous exposure to chlorine, fluorine, and silane mixtures in semiconductor CVD processes. Please consult our application engineers with your gas composition and concentration.

Q: What is the advantage of a central vacuum plant over distributed pumps?

A central plant offers three main benefits: (1) Energy savings — multiple smaller pumps often run inefficiently at partial load; a central system with VFD and sequencing runs only the needed capacity. (2) Reliability — N+1 redundancy and automatic standby switching eliminate production stops if a pump fails. (3) Maintenance convenience — all pumps are in one location with proper ventilation and exhaust treatment. Additionally, central plants reduce heat and noise in the production area. The break‑even point is typically 10+ connection points or a total pumping speed > 1000 m³/h.

Robust Vacuum Generation & Power Solutions

The heart of any vacuum system is its pumping architecture. AIMRSE delivers a full spectrum of generation technologies — from dry oil‑free scroll pumps for cleanroom load‑locks, to oil‑sealed rotary vane pumps for rough vacuum, high‑speed turbo‑molecular pumps for UHV, and roots booster combinations for high‑throughput industrial processes. We also design factory‑wide central vacuum plants with automatic standby switching and variable frequency drives. Every system is sized using rigorous gas load modeling and backed by lifetime support. Whether you need a standalone laboratory pump or a fully integrated pumping skid for semiconductor etching, our solutions prioritize pumping speed, ultimate pressure, energy efficiency, and uptime.

Engineering Priorities for Vacuum Generation

Maximized Pumping Speed & Throughput

Optimizing effective pumping speed (Seff) for each process regime — from rough vacuum to high vacuum — by matching pump type, foreline conductance, and gas load. Our designs reduce evacuation time by up to 40% in large chambers.

Ultimate Pressure & Base Vacuum Stability

Achieving and maintaining base pressures down to 10⁻⁸ mbar for turbo‑molecular systems and 10⁻³ mbar for dry scroll pumps. We use helium leak‑tested flanges and low‑outgassing materials to eliminate virtual leaks.

Energy Efficiency & Lifecycle Cost Reduction

Variable frequency drives (VFD) on roots pumps, automatic idle‑mode for turbo pumps, and centralized plants with staggered startup reduce energy consumption by 25–35% compared to fixed‑speed systems.

Real users' feedback from industrial and research clients on our reliable vacuum equipment and professional support.

"We replaced four distributed oil‑sealed pumps with a single AIMRSE central vacuum plant for our packaging lines. The energy saving has been 32%, and the automatic standby switching eliminated production stops during pump maintenance. Their team did a full site survey, installed the receiver tank and filtration, and integrated the system with our existing PLC. Highly recommended for any factory looking to reduce vacuum energy costs."
