Pre-Coat Pressure Filters

Additional Details

We manufacture Pre-Coat Pressure Filters which are designed for easy manual cleaning. Dirty fluid with “filter aid powder” is fed under pressure at the filter inlet so that it forms a uniform layer on the filter discs in the filter shell. During this process the filter outlet fluid is diverted back to dirty fluid tank. This operation is called “pre-coating”. It is performed every-time after the filter is cleaned & put to use again. 

After pre-coating the filter used to clean the fluid tank. Through separate pump the clean fluid is supplied to the machine. To increase the time of service for the filter a small amount of filter aid powder is fed periodically at the dirty pump suction point. This operation is called “body feeding”. Excellent filtration clarity is generated for high finishing. Once the filter is choked, (usually at pressure drop of 1.5 bar.) the filter housing is drained, purged with compressed air & then opened. The discs are dismantled & cleaned manually using compressed air. Our pre-coat pressure filter give a Super-finishing, finish grinding, honing etc. It can commonly be used for individual machines.
