These fans may be used to supply relatively low volumes of air under pressure of up to 10 000Pa. These fans are highly efficiency. High-pressure centrifugal fans are used as blowers, or for delivery pressure-pneumatic systems, etc.
ВР-120-28 fans are:
• manufactured according to the 1st or 5th design versions
• manufactured with right-hand or left-hand rotation;
• manufactured with direct motor drive or with belting drive.
These fans are designed for operation in temperate (У), moderately cold (УХЛ), cold (ХЛ), dry tropical (ТС), humid tropical (ТВ), or maritime tropical (ТМ) location climate category 2 as per GOST 15150.
Operation of У, УХЛ, ХЛ, ТС, ТВ, or ТМ climatic category fans of the 1st category of location is possible providing that fan is weather-protected.
