Key Technical Features & Performance Advantages

🌿

100% Oil-Free & Zero Maintenance

Self-lubricating piston seals eliminate oil contamination in vacuum lines, requiring no lubrication maintenance and guaranteeing pure process exhaust environments.

🎯

High Vacuum Depth (-740 mmHg / -98 kPa)

High-vacuum "H" models reach up to -740 mmHg (-98 kPa), providing exceptional holding force for suction cups, laboratory filtration, and medical negative pressure.

🤫

Ultra-Quiet Operation (56 - 60 dB)

Precision-balanced internal drive coupled with noise-dampening intake mufflers maintains quiet sound levels suitable for direct indoor laboratory and hospital use.

🛡️

Built-In Overload Thermal Protection

Integrated thermal cut-off switches prevent motor overheating or damage under severe voltage fluctuations or continuous heavy-duty work cycles.

Target Applications & Industry Uses

🏥 Medical Systems & Hospital Negative Pressure

Essential for dental suction units, hospital negative pressure cabinets, medical aspiration systems, and bio-pharmaceutical equipment.

🔬 Laboratory Devices & Analytical Instruments

Provides stable vacuum for rotary evaporators, vacuum filtration manifolds, desiccators, and mass spectrometer backing setups.

🤖 Electronics, Semiconductor & Pick-and-Place

Frequently Asked Questions (FAQ)

What are the core technical specifications of the VB series oil-free piston vacuum pumps?

The VB series covers power options from 0.16 kW to 0.67 kW across 110V/220V dual voltages (50Hz/60Hz). It offers maximum flow rates from 50 L/min to 208 L/min, ultimate vacuum levels up to -740 mmHg (-98 kPa), quiet operation between 56 dB(A) and 60 dB(A), and standard 1/4" or 3/8" NPT/G port connections.

Why is 100% oil-free design critical for medical and laboratory applications?

The 100% oil-free construction eliminates oil mist contamination in exhaust streams and working environments, making it mandatory for hospital negative pressure suction, dental equipment, laboratory filtration, electronics manufacturing, and food packaging.

How does the built-in overload protection ensure pump longevity?

Every VB series piston pump is equipped with an integrated thermal overload protector that automatically cuts power if excessive current or high ambient temperatures occur, preventing motor burnout during continuous duty cycles.

What standard accessories are included with each VB vacuum pump shipment?

Each pump includes a complimentary accessory kit containing a high-efficiency inlet air filter, exhaust silencer/muffler, rubber anti-vibration feet, and quick-connect pneumatic hose fittings.
