Frequently Asked Questions
What is the difference between a single-stage and a dual-stage vacuum pump?
A single-stage vacuum pump exhausts directly into the atmosphere and is ideal for standard vacuum requirements (down to 2 Pa). A dual-stage vacuum pump features two rotors and chambers in series, where the second stage exhausts into the first stage, resulting in a much higher ultimate vacuum (down to 2x10⁻¹ Pa / 15 Micron).
What voltage range do these vacuum pumps support?
Our vacuum pumps are designed to be highly versatile, supporting a voltage range from 110V to 220V, making them compatible with various power grids globally.
What are the primary applications of these pumps?
These rotary vacuum pumps are suitable for family homes, the food and beverage industry, HVAC OEM, industrial boilers, industrial utilities, temperature control systems, and washing/cleaning applications.
How does the anti-suckback design protect the system?
The integrated anti-suckback mechanism prevents vacuum pump oil from flowing backward into the vacuum chamber when the pump stops, protecting your vacuum system and workpieces from contamination.
Why is the aluminum alloy casing beneficial?
The durable and robust aluminum alloy casing offers excellent heat dissipation properties, keeping the pump running cool and extending its overall service life while reducing the unit's weight.
