More About Vacuum Flow
I can always tell when I touch on a new subject – I get emails. As I said in my last post, the amount of open flow is the most important spec to look at when choosing a hearing aid vacuum. Flow is a concept that is a little more difficult to understand, so advertisers use the “Hg specification to prove they have the most power. I would rather have less power and more flow for cleaning hearing aids because flow is the movement of air, and that is going to move the debris out of the hearing aid. Of course, if you can have flow and power you’ve got a winner.
Here’s an example: I got a call from a local Beltone dealer who had questions about her vacuum pump. She had just bought an Aura-Clean and she was really expecting more results. I had never seen an Aura-Clean in person, so I volunteered to stop by with our VAC-1 to compare. I turned her vacuum pump on and plugged the end of the vacuum tubing with my finger. Maximum vacuum was 22” Hg – not bad for power. But, what I did notice was it seemed to take forever for the vacuum gauge to get there. That told me the pump didn’t have a lot of flow, and therefore wasn’t going to be effective for cleaning hearing aids. I demonstrated the VAC-1 and it just blew the Aura-Clean away (plus it’s less expensive). We also compared our Lightning Vac 2. That is a smaller unit with 15”Hg, but has an incredible 4 lpm of flow.
She ended up getting our VAC-1 – everyone that tries one does.
