Uses and Features
PB fan series are industrial centrifugal fans designed to operate at high pressures. The fans are built with a HEAVY DUTY industrial design and are suitable for continuous process operation, under extreme conditions of pressure, temperature, dust, and corrosion. PB type fans are used for high-pressure suction and filtration systems, edge extraction systems, pneumatic conveying and waste removal systems, and 'air knife' systems. A fan can be supplied with an open radial booster PBM for air intake with a high particle load and waste conveying.
