| AIR AGITATION
UNITS |
|
Many modern plating and subordinate solutions
use agitation, in one form or another, to improve the
conditions of operation.
In electroplating, agitation serves the purpose of frequently
renewing the cathode film, thus decreasing polarization
and enabling the use of higher current densities with
consequent finer grain deposits at higher speeds.
|
| These
are available in different types:- |
|

TURBINE
BLOWER
|
|
These blowers consist of
a dynamically balanced impeller, which revolves
in as stator-cum compression chamber having
very fine clearances between them. The impeller
is fitted directly on to the motor. Both
the suction and pressure openings are located
on the outer periphery of the stator to
reduce impedence to the air flow thereby
developing vacuum and pressure.
|
| Feature: |
|
•
|
No
lubrication is required since there
is no friction and hence the air is
absolutely oil free. |
|
•
|
Practically
nil maintenance cost. |
|
•
|
Extremely
compact unit and can be mounted inside
the machines. |
|
•
|
Silencer
ensures low noise. |

WATER
WASHED AIR AGITATION
|
|
This is a rotary air unit,
complete with air vessel, fitted with safety
valve and water level indicator. It provides
clean, water washed air for agitation and
does not require oil for lubrication. It
is kept cool and lubricated by the circulation
of water. On account of this, danger of
contamination of plating solution with atomised
oil of air is avoided. The air receiver
vessel is hot dip galvanised to resist against
rusting.

DIAPHRAGM
BLOWER UNITS
|
|
These are portable Mini
Diaphragm Compressor. They provide oil free
air with built-in Micro Air Filter. Noise
volume is low and hence they are suitable
for small Plating Plants and Laboratory
etc. Capacity 1.75 CFM & 50 Psi in single
Diaphragm Die and 2.8 CFM & 50 Psi in double
Diaphragm Die.
