Automated VPA
According to type of protection against the access to dangerous parts and water
penetration:
the motors used in
VPA
are related to devices of Class IP 44 (protection against the
bodies with size more than or equal to 1,0 mm; protected against the water splashes);
—
VPA
installed in the pipeline is related to devices of Class IP 22 (protection against the
bodies with size more than or equal to 12.5 mm; protected against the water drops falling
down vertically when the casing is deVPAted at angle of 15 °).
Example of design letters:
Ventilation input unit VPA, diameter of connecting tubes 150 mm, heater power 6.0 kW,
phase connection:
«VENTS VPA 150-6.0-3»
Basic technical parameters correspond to values shown in table 1. Overall and mounting
dimensions are shown in table 2 and in fig. 1.
VPA design is improved continuously and, therefore, some models can slightly differ
from those described in this operating manual.
