Key Features

1. 2-Stage Rotary Vane Design-Dual compression stages achieve deeper vacuum than single-stage pumps, reaching ultimate pressure of 0.5 Pa for demanding applications.
2. Oil-Sealed Operation-Built-in oil reservoir lubricates and seals vanes continuously, reducing friction and extending pump lifespan significantly.
3. Built-in Gas Ballast Valve-The gas ballast system prevents oil contamination when pumping condensable vapors, protecting performance and reducing oil change frequency.
4. Low Noise Operation-Precision-balanced rotor and quality bearings keep operating noise low, making this pump suitable for lab environments and enclosed workspaces.
5. Universal Motor Voltage-Compatible with 220V/50Hz power supply standard in Bangladesh, with thermal overload protection for reliable long-term operation.
6. Easy Maintenance Access-Simple oil drain and fill ports, plus an accessible exhaust filter, allow technicians to service the pump quickly without specialist tools.
7. Compact, Portable Frame-Sturdy handle and compact footprint allow easy transport between job sites while maintaining stability during operation.
8. Anti-Suckback Protection-Integrated anti-suckback valve prevents oil from entering the vacuum system when the operator switches off the pump.

Frequently Asked Questions (FAQ)

Q1. What makes the VP245 a 2-stage rotary vane vacuum pump different from a single-stage model?

A 2-stage design compresses gas in two sequential steps, which allows the VP245 to reach a much deeper ultimate vacuum — down to 0.5 Pa — compared to single-stage pumps that typically reach only 5–10 Pa. This makes the VP245 suitable for laboratory and precision industrial work where high vacuum quality matters.

Q2. How often does the VP245 need an oil change?

Under normal operating conditions, the pump requires an oil change every 500 hours of use or every six months, whichever comes first. Users who pump condensable vapors regularly should change the oil more frequently to maintain pump performance and protect internal components.

Q3. Can HVAC technicians use the VP245 for evacuating refrigerant lines?

Absolutely. HVAC professionals widely use this pump to evacuate refrigerant systems before recharging. The deep vacuum capability removes moisture and non-condensable gases effectively from AC and refrigeration systems, ensuring a clean and efficient charge.

Q4. What vacuum pump oil does the VP245 require?

The pump requires dedicated vacuum pump oil with a viscosity grade of ISO VG 68. Standard motor oils or hydraulic oils damage internal components and void the warranty. ASTZBD stocks compatible vacuum pump oil separately for purchase alongside the VP245.

Q5. Does the VP245 come with a warranty when purchased from ASTZBD?

Yes. Every VP245 purchased from ASTZBD includes a 12-month warranty. The local after-sales team handles warranty claims directly, so buyers do not need to contact overseas manufacturers or ship the pump abroad for service.
