Protection measures for outdoor storage
� Cover the machine with waterproof cloth to ensure that the motor parts of the machine are well protected;
make sure ventilation is enough to prevent water condensation; cover the air inlet and air outlet.
(warning: using black plastic cover may cause excessive moisture conden-sation and corrosion.)
� If there is water condensation and accumulation, appropriate draining should be undertaken.
Protection measures for indoor and outdoor storage
� If the machine is stored for a long time (4-6 months or longer), it is necessary to turn the fan monthly
to prevent bearing damage.
� Do not place heavy objects on top of the machine.
� PURAFIL filter material should be stored in a dry place with relative humidity lower than 95%.
1.5 Space reserved for installation
Space reserved for installation
� The machine should be installed in a place where the air inlet and outlet are not blocked.
� The machine should be installed in a place convenient for loading and unloading the molecular filter
module and the particle filter.
2.0 Machine design
2.1 Product application
PURFAFIL commercial air purifier CPUM-1000 is an internal circulation air purification system. Its main
components include a two-stage gaseous pollutant purification module, a particulate pollutant filter, an air
blower and motor components.
2.2 How the machine works
PURAFIL PuraShield commercial air purifier uses a two-stage molecular filter module to recycle and
purify air in the controlled space. The two-stage molecular filter section can effectively remove corrosive
gas pollution with an efficiency of more than 99%.
