Frequently Asked Questions
What is the Holland Green Science Anemos scroll pump?
It's an oil free dry scroll vacuum pump with a 12 m³/h displacement and a 0.15 mbar ultimate vacuum. It suits freeze drying, short path distillation, vacuum ovens and general lab work, anywhere you want a clean vacuum with no oil in the mix.
Does the Anemos scroll pump work with the Xiros Mikro freeze dryer?
Yes. There is an installation video online showing it fitted to a Xiros Mikro, and its 400W motor sits well inside the 3A maximum the Xiros Mikro lists for its pump. It is sold separately from the freeze dryer.
Does the Anemos scroll pump need oil?
No. It's a dry scroll design, so there is no oil to top up or change and no oil to contaminate the system you are pumping on. Upkeep is a periodic check over and keeping the inlet filter clean.
How loud is the Anemos scroll pump?
54 dB(A) on the listing. That is quiet for a vacuum pump, but you will still hear it, so give it some breathing room rather than sticking it right next to your desk.
What vacuum can the Anemos scroll pump reach?
0.15 mbar ultimate vacuum, with a 12 m³/h displacement. That is the pump on its own, so the vacuum you actually see in a chamber also depends on your fittings, seals and what you are drying.
Is a pump included with the Xiros Mikro freeze dryer?
No. The Xiros Mikro ships without a vacuum pump and needs an oil free scroll pump rated 3A max, so you buy one separately. The Anemos is the one to pair it with.
Description
The Holland Green Science Anemos is an oil free dry scroll vacuum pump, 12 m³/h with a 0.15 mbar ultimate vacuum, for anyone who wants a clean vacuum without messing about with pump oil. Mostly that means people running a freeze dryer, and there is an installation video online showing it being fitted to the Holland Green Science Xiros Mikro Benchtop Freeze Dryer. It also suits short path distillation, vacuum ovens and drying chambers, and general lab vacuum work.

In the box
The Anemos scroll pump itself. The supplier does not publish a full contents list, so check what turns up before you bin any packaging. Power lead, NW25 clamps, centring rings, O-rings and any hose adaptors are exactly the sort of small bits that get thrown out with the box by mistake. If you need to know what comes with it before you order, get in touch and we will find out.
Why Go for a Dry Scroll Pump
A dry scroll pump has no oil to change and no oil to contaminate whatever it is connected to. That is the whole appeal over a rotary vane pump, which needs regular oil changes and can backstream oil vapour into the system. The Anemos is also compact at 430 x 255 x 290mm and runs at 54dB(A), so it is not the screaming beast a lot of vacuum pumps are.
Setting Up and Looking After the Anemos
Stand it on a stable, level surface with plenty of ventilation, because it is air-cooled and needs to breathe. Check it over now and then and keep the inlet filter clean. Keep corrosive gases and particulates out of it, as they can damage the scroll internals. It weighs 28kg, so get a second pair of hands when you move it.
Who the Holland Green Science Anemos Is For
Anyone running a freeze dryer who needs a proper oil free pump, mainly Xiros Mikro owners. It is also a sensible pick for short path distillation setups, vacuum ovens and drying chambers where oil contamination would ruin the batch.
