Reverse Jet Filter

	CROPCARE SYSTEMS Reverse jet filter is of robust construction and circular in design which also aides a smooth flow of the dust laden air into the filter chamber. The chamber contains a number of filter bags supported on a heavy filter cage and mounted within a sealed floor.
OPERATION The dust laden air is forced into the filter chamber via negative/positive pressure or a combination of both and the fine dust settles on the outside of the filter bags. This allows the air to penetrate the filter material, so clean air is discharged through the outlet in the top section of the filter.
	At a given frequency a pulse of scavenging air (short powerful blast of compressed air) is blown down the inside of the filter bag. This momentarily inflates the filter bag causing the combined effect of a ‘shake’ and a reverse air blast. It is a combination which efficiently cleans the filter bag. The frequency of the pulses and the pauses can be adjusted to suit the actual site conditions by the operator. The scavenging system control will pulse through each individual valve in turn, this minimises the filter air required and reduces the compressed air requirements. Once the dust has been removed from the filter bag, it settles in the bottom of the cone where it can be discharged and handled in different ways, such as rotary valve, screw conveyor, etc. this depends on the amount of dust and the type of plant/factory.
