The high precision of filter: the primary filter material adopts PTFE filter material and the secondary filter material adopts HEPA or ULPA filter. Against the interception of ultra-fine dust up to 0.3um, the dust removal rate is over 99.9%.

Reasonable design: modular design, block type assembly, extremely convenient installation.

The high precision of processing technique: laser cutting technique, NC punching and shearing technique, NC bending technique, automatic welder machine and model fixture assembly.
