What happens if there is dust emission lost the function:
Check the filter system and Change the filter bags every 3 months.
The price of each is $30 /pc
– Remarks
Starsplas will send the operation mode of dust collectors, and DWGs
Starsplas will check to cope with the 5mg/m³ emission rate
Filters installation method will be sent. Maintenance every 3-4 months but it depends on usage.
Pneumatic pulse generates dust waves due to the reduce dimension of the pilot line dust collector.
Sealing of inspection door with rubber band.
– During FAT
Verification of dust emission rate of 5mg/m³.
