Centralised filtration system is basically a common filtration system for a group of machines. If you want to reduce your Cost per component ( CPC ) then centralized filtration system along with swarf handling system can go a long way in helping you.

By implementing a central filtration system you can save upto
• 25% in shop floor area
• 50% in electricity cost
• Increase life of coolant by 10 times
• Reduce manpower required by 50%

True to our motto DISCUSS DESIGN DELIVER we will help you out from concept to after sales.

Veeraja has successfully implemented hundreds of central filtration systems for :
• Aluminum machining
• Cast Iron Machining
• Steel grinding
• Steel Honing

Working :
A perforated top vacuum chamber is placed at the bottom of dirty coolant tank. Machine outlet lets dirty coolant in this tank. A pump sucks coolant through filter paper laid on top of vacuum chamber, leaving dirt on filter paper. Pump suction generates vacuum increasing dirt layer thickness & hence finer filtration.

After preset level of vacuum is reached, it is broken temporarily by opening actuated by-pass valve. Part of dirt-laden filter paper is pulled out to be replaced by fresh filter paper. Dirt is dumped in a bin while dirty filter paper is wound on a shaft.

Applications :
Suitable for fine filtration of coolants used in grinding, honing, gun drilling & component washing applications.

Features :
Better filtration is achieved using lesser filter paper. This gives better quality at lesser operational cost. Can handle more viscous fluids. Totally automatic operation. Can be built as individual machine unit or centralized plant.

Working :
Fluid with dirt is exposed to finned magnetic separator first. After magnetic separation the fluid drops in paper band filter trough. A float-actuated clutch derives motion from a common drive & indexes dirty filter paper.

Applications :
Suitable for fine coolant filtration for honing, grinding, lapping, gun drilling etc., for small individual machines.

Features :
• Very compact. Magnetic separator & band filter combination is accommodated within
• 150 mm above the tank top, reducing the floor area for same volume of tank.
• Band filter unit is mounted on rollers for ease of shifting during tank cleaning.
• Common drive for magnetic separator & paper band filter, makes it economic.
• No electrical panel hence reduced cost & maintenance.
• Dirty filter paper is wound on a mandrel for easy disposal while the dirt collected is stored in a bin.
• Absence of conveyer, shafts, rollers, makes it more maintenance friendly.

Self Cleaning filter holds multiple elements ( based on flow capacity ) housed in a pressure vessel. The dirty fluid enters from the bottom into the inner side of these elements. The dirt starts accumulating on the inner surface. This accumulated dirt increases the differential pressure, which is sensed by a pressure switch.

On reaching a set differential pressure an dedicated panel start the backwash cycle.
A rotating arm, placed under the elements, connects the element opening to atmospheric pressure. As the complete housing is operating at a higher pressure, the fluid starts a reverse flow from outside to inside for that particular housing. This flow dislodges the accumulated dirt on the inner surface and that particular element is backwashed.

After a set time delay the backwash arm rotates to the next element. This countinues until all elements are backwashed. Various elements of filtration level upto 150 micron are available. Number of elements in the housing are decided on the process, flow and dirt load.

Features :
• Completely automatic
• Robust design

Application :
• Roll coolant filtration system
• Cooling tower water filtration
• Water filtration system for Boiler feed
• Food processing etc.

Working :
Dirty fluid is fed under pressure in to inlet manifold. It is distributed equally in 4 different plates. Filter papers clamped & supported between plates separate the dirt & form a layer (cake). This effects finer filtration. The same filter with pre-coating can add further to fineness of filtration.

Applications :
Suitable as centralized fine coolant filtration for finish grinding, filtration of high viscosity grinding fluids & filtration of honing oil with pre-coat arrangement.

Features :
• Very large filtration area is accommodated relatively small dimensions. The unit shown is having 10 m2 filtration area.
• Totally automatic pneumatically actuated operation.
• Dirt is purged with compressed air to recover fluid.
• Low initial & operational costs.
