Description
Introduction VALUE VE225N vacuum pump
The VALUE VE225N vacuum pump removes air and moisture from refrigeration systems quickly and completely. Its two-stage rotary vane design reaches an ultimate vacuum of 15 microns, therefore it outperforms single-stage pumps on moisture-heavy jobs. The 1/4 HP motor drives a 2.5 CFM flow rate, so you evacuate split units, chest freezers and small commercial lines in minutes rather than hours. VALUE VE225N vacuum pump, VE225N price in Bangladesh

Key Features VE225N price in Bangladesh
- Dual-stage rotary vane design — the second stage pulls the system down to 15 microns, so moisture leaves the lines completely.
- 2.5 CFM free air displacement — the pump clears typical 1–2 ton split systems in minutes.
- 1/4 HP high-torque motor — it starts reliably under load, even during low-voltage conditions.
- Forced oil-cooling circuit — this system controls heat, therefore the pump runs longer without fade.
- Gas ballast valve — it purges vapour from the oil and consequently protects vacuum depth.
- Oversized sight glass — you read oil level and colour without opening the housing.
- Integrated aluminium body — the one-piece casting seals better and resists workshop knocks.
- 1/4″ SAE flare inlet — it connects straight to standard manifold gauge hoses.
- Low-noise operation — the balanced rotor keeps sound levels comfortable indoors.
- Portable 7 kg frame — the moulded handle makes rooftop and ladder work manageable.

Who Uses This VALUE VE225N vacuum pump
- HVAC technicians rely on the VE225N for daily installation work.
- Refrigeration mechanics use it while repairing fridges, freezers and display chillers.
- Automotive AC workshops evacuate car systems with it before charging R134a. Moreover,
- laboratory staff connect it to filtration flasks and desiccators for routine degassing.
- Polytechnic and vocational institutes buy it for RAC training labs, since students learn deep-vacuum procedure on real equipment. Finally,
- facility maintenance teams in hotels, hospitals and factories keep one on hand for in-house AC servicing.

Frequently Asked Questions (FAQ) dual stage vacuum pump
Q1. What vacuum level does the VALUE VE225N vacuum pump reach?
It reaches 15 microns of total pressure. Therefore, it pulls a deeper vacuum than any single-stage pump in the same power class.
Q2. Which systems suit this 2.5 CFM capacity?
Use it on split ACs up to roughly 2 tons, refrigerators, freezers, water coolers and car AC systems. For large VRF or commercial chillers, however, choose a 6–12 CFM model instead.
Q3. Does the pump work with R410A?
Yes. The VE225N handles R410A, R134a, R404A, R407C, R507 and R22 systems.
Q4. Which oil does it need, and how much?
Use genuine VALUE vacuum pump oil. The reservoir holds 250 ml. Moreover, you should change the oil after every 20–25 hours of running or whenever the oil turns cloudy.
Q5. How long should I run the pump on a split AC?
Run it for 20–30 minutes on a standard indoor-outdoor installation. In humid weather, however, extend the time and open the gas ballast valve to purge moisture.
Q6. Does the package include hoses or a gauge set?
No. The box contains the pump, oil and the manual. You can add a manifold gauge set and micron gauge from our accessories range.
Q7. Can I use it for laboratory filtration?
Yes. Many labs connect it to filtration flasks and desiccators. Because of the dual-stage design, it also degasses resins and silicone effectively.
Q8. What warranty does ASTZBD provide?
We provide a 6-month seller warranty against manufacturing defects. Normal wear items such as oil and seals fall outside this cover.
Q9. Do you deliver outside Dhaka?
Yes. We ship nationwide through trusted couriers, and most districts receive delivery within two to three working days.
Q10. Why does my pump not reach 15 microns?
Check the oil first, since contaminated oil limits vacuum depth. Next, inspect the hose gaskets and the flare connections for leaks. Finally, confirm your micron gauge reads accurately.
