Cyclone

The Dyson vacuum cleaner was first promoted with a downright lie.

No bag = 100% suction & efficiency

A bag is a filter that collects all particulates and the fines clog up the pores and restrict the airflow, Dyson replaced the 300 sq in. bag with two inline much smaller 20 sq in. filters.

In my opinion the bag is more efficient, cleaner and easier and the bag cost less to buy and RUN

INDUSTRIAL CYCLONES

CAN‘T BE 100%

EFFICIENT

OR CAN THEY

I should not call this an invention even though I

have done a lot of work and development on it. It's

probably better to call it a concept. It started because I

had spent 15 years fitting duct, filters and cyclones in

factories and as is usually the case, I thought I could do

better. I knew that cyclones weren‘t that efficient and

were now being phased out in favour of cloth filters

because with the advent of cheap composite boards it

was no longer acceptable to have 15 to 20% of now

toxic fines venting to atmosphere. It would be more cost

effective to dispose of the cyclone altogether and make

large filter bags big enough to take large particles like

wood shavings as well as the fine saw dust.

I reasoned that a crude centrifugal pre-separator

made from a cheap standard 45gal drum would allow

for a much slimmer cloth filter in a smaller housing and

might be better overall.

I knew that centrifugal separation depended on

the air speed attained in a cylinder and I also knew that

conventional cyclones depended in part on the cone

shape to increase the speed and make them

economically separate out around 90 to 93% in a high

efficiency one. YOU can possibly understand my

surprise and disbelief when I got 98% in my

configuration with a standard 45gal drum. Not possible,

I‘ve done something wrong. But now I know it is

possible the tests are absolutely correct, because I

understand the HOW and WHY logically.

Manufacturers did not want to know unless it

was proved to be 100% efficient on particles of .1 of a micron.

Based on the results never before seen in such a

crude prototype I pinpointed the only possible reason

why 100% is not attained. Tests have been done on the

point mentioned and I have the results from the tests

that suggest that 100% is attainable BUT it's beyond

my financial capabilities. If you want to know more you
