9.0 COMPRESSED AIR SUPPLY
NOTE: The compressed air installation should be performed by a qualified installer and in accordance with local, state, and national codes/regulations/laws (if any).
9.1 The compressed air supply is used to clean the dust coated cartridge filters with a high pressure reverse jet pulse. A 2” diameter (minimum 1.5” diameter) dedicated supply with a mi nimum of 90 PSI and a maximum of 100 PSI is recommended. If a supply line smaller than 1.5” is used, then a 30-gallon accumulator tank should be installed with a 2” line from the tank to the collector manifold. The largest supply line available should feed the accumulator tank. The unit has a 2” diameter connection. 9.2 The air supply line to the accumulator tank must include water, oil and particulate filtration. Water and, especially, oil in the compressed air will significantly reduce the effectiveness of the reverse jet pulse cleaning by destroying the cartridge filters and causing excessive differential pressure across the filters, which results in greatly reduced air flow along with premature filter replacement.
NOTE: The air line MUST be free of oil and water to avoid failure of cartridge filters
9.3 A 200 PSI gage must be installed to monitor air pressure. Prior to the final connection of the air line to the collector manifold, the air line should be purged. This will remove debris that could damage the valves and block the nozzles in the blow pipes.
9.4 When installing the compressed air supply to the air manifold(s), refer to the diagrams below.
