Adapter Ring with Vacuum Indicator and Shock Valve
The motor top is mounted on the adapter ring and fastened with three
container clips. A vacuum indicator (1) and a shock valve (2) are mounted
on the adapter ring.
The vacuum indicator measures the vacuum between the multi-tube filter
and the HEPA-filter. The scale of the vacuum indicator has a green and
red area. If the pointer reaches the red area during operation, it indicates
that the filter is being blocked and that the air velocity in the suction hose
consequently will fall and become too small. You can clean the filter
during operation by using the shock valve.
Filter Container with Multi-Tube Filter
The large multi-tube filter of the RONDA
the filter container. The multi-tube filter has been tested with
quartz-dust particles, of which more than half is less than 5 m. (5
m is the same as 0.005 mm.)
The surface of the filter is 1.87 m
The Teflon-coating repels the dust, which will in this way not stick
so easily to the filter material.
The filter consists of a large number of tubes (channels) mounted
on springs. During operation the tubes vibrate, and part of the
dust sucked on to the surface of the filter will fall down in the
collection container.
