Cartridge Recovery Powder Spray Booth

Please refer comparison chart.

The high efficiency fan sucks the air and overspray powder through spray booth towards the cartridge filters. The powder is blocked by the cartridge filters and only clean air is released into the atmosphere.

Powder deposited on the outer surface of the filter will be dislodged by the high pressure air which is purged by Mitsuba’s unique Rotating Wing Cleaning Mechanism.

Rotating Wing Cleaning Mechanism rotates inside the cartridge filter at very high speed for the set time. While rotating inside the cartridge it also purges the air at pressure inside the cartridge. The purged air is introduced across the height of the cartridge. The purged air will dislodge the powder which is deposited on outer surface of the cartridge filter.

Conventionally, cartridge filters are cleaned by reverse pulse jet system. Reverse pulse jet system releases a high pressure jet of air inside the cartridge. The shock generated by the air blast dislodges the powder deposited on the outer surface of the cartridge. The shock of air in this cleaning mechanism never reaches the bottom section of the cartridge filters. The powder will accumulate on the cartridge and will result in higher pressure drop and powder will escape out of the booth into the atmosphere. While rotating wing cleaning mechanism will purge the air uniformly throughout the height of the cartridge and will keep the cartridge clean all the time. With Rotating Wing Cleaning Mechanism no powder will escape out in the atmosphere.

The old powder is mixed with new powder to achieve the desired powder particle size distribution. In the cyclone recovery, powder particle size changes after every cycle. To maintain the desired particle size distribution new and old powder is mixed. The cartridge recovery does not change the particle size distribution in recovered powder over fresh powder. Recovered powder can be used as it is for consistent quality coating.

No, it is not recommended. There is a very high possibility that it will contaminate the powder. The standard practice is to keep dedicated cartridge filters for each colour.

Yes, we can.

We need sizes of the products to be coated, conveyor speed, entry-exit cut out of the booth and the number of colours you will operate.
